Conform celor 238,468 recenzii, clienții îi evaluează pe Java Developers cu 4.9 din 5 stele.I’m ready to turn a fresh idea into a fully-functional Android app and I need an experienced mobile software developer to work with me from concept to launch. This project is strictly for Android, so deep familiarity with Android Studio, Kotlin or Java, common libraries, and Google Play deployment is essential. Here’s what I have so far: a clear problem the app will solve, basic wireframe sketches, and a short feature wish-list. What I’m missing—and what I’m hiring you for—is the technical build, iterative testing, and guidance on best practices so the final APK meets current Play Store requirements and runs smoothly on modern Android devices. Deliverables I expect: • Clean, well-commented source code hosted in a shared repo • A signed, rel...
I’m ready to turn my working title “GoGogogogogp” into a fully-featured Android application. The project is strictly app development—no web or iOS work for now—so I need someone who can take the idea from blank screen to a polished release on Google Play. Here’s what the engagement will look like: • Collaborate with me to refine the feature set, then translate it into a clean, modern Android interface. • Build the app natively in Kotlin or Java inside Android Studio, following Material Design best practices for performance and accessibility. • Connect any required back-end services (Firebase, REST API, or a solution you recommend) and implement secure local data storage. • Run thorough functional and usability tests, fix bugs,...
I need a straightforward Android application that simply wraps my existing site, shiftxpress.in. When a user opens the app, it should load the public website exactly as it appears in a mobile browser—no extra screens, log-in, or separate navigation. Behind the scenes, my private web application (the admin area) must still be reachable through its current URL, yet remain invisible to normal users just as it is on the site today. I am only targeting Android, so please build with native Android Studio (Java or Kotlin) or a reliable cross-platform tool that compiles to a clean Android package. A lightweight WebView container with proper handling for links that open outside the domain, file uploads, basic permissions, and back-button navigation will cover everything I need. Deliverables...
I’m building a new Android-only social media app focused on two pillars: rich media sharing and a Stories feed. The experience should feel familiar to users of today’s visual networks, yet remain lightweight and smooth on a wide range of devices. Key requirements • Seamless integration with Snapchat’s SDK so that users can sign in with, share to, or pull content from their Snapchat accounts. If you have a preferred method for handling Snapchat’s Login Kit or Creative Kit, let me know—flexibility is welcome as long as the final flow is frictionless. • Core features: photo / video uploads (both from camera and gallery), an auto-expiring Stories carousel, basic reactions, and a clean, swipe-driven interface. • Modern Android stack—Kotlin...
I already have the core of an ERP SaaS platform in place, built with Java 17, Spring Boot, Spring Data JPA, RESTful APIs, and a MySQL backend. What I need now is a fully-featured Customer Relationship Management module that my employees can use day-to-day inside the same application. The scope of this engagement is limited to CRM functions only, but they must plug seamlessly into the existing codebase and follow its clean-architecture approach: • Lead Management – endpoints, UI pages, and persistence layers that let staff capture, qualify, score, and assign leads. • Sales Tracking – pipeline views, deal stages, and automated status updates tied to existing authentication and role policies. • Customer Support – ticket creation, SLA timers, comment thre...

I run an online store and need a robust AI-driven chatbot that can live on my website, greet visitors, and resolve their questions without human intervention. It must respond in a formal, professional tone and reliably cover three core request types: • Product information • Order tracking • Technical support From natural-language understanding to API hookups, every element has to feel seamless to the user. I am comfortable with Dialogflow, IBM Watson, Microsoft Bot Framework, or any comparable stack—choose the tech you believe will deliver the fastest, most accurate results and let me know why. Key results I expect: • A fully trained, production-ready chatbot embedded on my site • Smooth handoff to live agents when a query falls outside the bot&rsq...
I’m building a bite-sized learning section inside our portal and want it stocked with engaging, India-made “reel” videos that make programmers stop scrolling and start coding. Every clip should focus on Programming Languages, specifically Python, Java, or JavaScript, and can take one of three angles: a concise tutorial that teaches a single concept, a rapid-fire set of tips & tricks, or a quick project walkthrough that shows the real-world use of the topic. Here’s the flow I have in mind • Format: vertical (9:16) or square, 60-90 seconds each, HD, .mp4 • Delivery style: screen capture with clear voice-over in neutral English; on-camera intro/outro optional but welcome • Tools: feel free to record with OBS, Camtasia, ScreenFlow, or any edito...
I have an Android app concept ready to move from wireframes to working code, and the first milestone is a solid, secure user-authentication flow. The job is to create a native Android application where new users can sign up, existing users log in, and forgotten passwords are recovered. Social sign-in (Google, Facebook, email/password) would be an added bonus if you’re comfortable wiring it up with Firebase Authentication, AWS Cognito, or another reliable backend. The design assets and basic screen sequence are finished; what’s missing is production-quality code that follows current Android guidelines, runs smoothly from Android 8 upward, and is easy to maintain. Kotlin or Java are both acceptable—just keep the project cleanly structured (MVVM preferred) and well document...

I keep a master Google Sheet that lists every authorised VIP in my Telegram community—username, numeric user-ID and email address on a single row. I need a scenario (formerly Integromat) that turns those records into a working identity-verification bot. Workflow I expect 1. A newcomer starts the bot in Telegram. 2. The bot asks for their Telegram @username (or reads it automatically) and, if not present, requests the numeric user-ID. 3. The scenario pulls the relevant row from my Google Sheet and cross-checks both fields (plus email when provided). 4. If the data matches, the bot sends a “Verified VIP” confirmation and automatically grants access to my private channel or group. 5. On any mismatch it returns a polite rejection message and logs the attempt in an...

Deliverable An installable APK plus complete, well-documented source code hosted in a private Git repository...
I have fallen several days behind on a set of Python-based programming and machine-learning assignments that live in Google Colab (links below). The notebooks already include starter code and task prompts, but a number of cells remain unfinished or are throwing errors. I need someone who can step in quickly, finish the required functions, debug the failing sections, and make sure each notebook runs top-to-bottom without issues. Google Colab notebooks 1. 2. 3.

I’m ready to move forward with a fresh Android application focused on smooth, reliable social-media integration. The core idea is to let users connect their existing social accounts, pull in profile details, and share in-app content directly to the major platforms without friction. Here’s what I need from you: • A clean, modern Android code-base (Kotlin preferred, but Java is fine) that follows current Google Play and Material Design guidelines. • Secure social sign-in and token handling for at least Facebook, Instagram, and X/Twitter, expandable to others later. • An intuitive UI/UX that shows off the social feed or sharing options clearly. • Clear, well-commented code plus a short setup README so I can compile and test builds locally. When we...
I have a complete Figma file and now need to see it running on real devices for an initial round of testing on both iOS and Android. The goal at this stage is to turn every screen in the design into a build that lets testers move through the full navigation flow, tap on all interactive elements, and submit information through the data-input forms exactly as they will in production. I’m still deciding whether user authentication is necessary for this phase, so structure the code in a way that will let us drop a simple login module in later without major refactoring. You can work with React Native, Flutter, or any other cross-platform stack you’re comfortable with; what matters is that I receive: • Two installable builds (TestFlight and an Android APK/Bundle) • Sou...

ErrorAnalyzer • Ingest console or build logs, identify stack traces, and correlate them with source files. • Primary p...
I run a large tech-news site with several thousand articles currently powered by Contentteller (PHP/MySQL). I have already chosen and purchased a new WordPress theme; what I need now is a developer who can move every piece of existing content into WordPress while keeping the site live, the URLs intact, and the search traffic unaffected. The job breaks down into three core pieces: • Export the full article archive—including body text, images, authorship data, dates and categories—from the Contentteller MySQL database. Whether you script the export in Java, generate XML, or follow another reliable route is completely up to you; my only requirement is that the process is seamless and nothing is lost. • Import that data into WordPress so it maps cleanly to the new them...

I’m providing the existing APK only and need it modified, re-compiled and signed so the app behaves and looks the way I want. The core focus is user interaction: • Buttons – several must be removed entirely, along with the code they trigger, so they no longer appear or respond. • Text and labels – copy needs updating to match new wording and, where necessary, stylistic changes (font size, colour) so the UI feels cleaner. • Data presentation – adjust how the current information is laid out on screen; cleaner grouping and clearer hierarchy are key. If altering these elements touches the navigation flow or form behaviour, feel free to propose improvements that remain consistent with the overall UX. Deliverables 1. Re-built APK ready to install and tes...
I need a robust YOLO model that spots vehicles with high accuracy. Because I do not yet have a labeled dataset, the job begins with sourcing or capturing varied vehicle images and annotating them in classic YOLO format. Once the dataset is in place, the next step is to train and validate the network—YOLOv5 or YOLOv8 are both fine as long as the final mAP holds up under real-world conditions. Please apply best-practice augmentation, tune hyper-parameters, and track training with clear metrics so I can reproduce the results later in PyTorch. Deliverables • Curated and fully annotated vehicle image dataset (bounding-box labels in YOLO txt format) • Trained YOLO weights and configuration files • Short report summarising dataset composition, training settings, and ev...

Ensure data integrity (no duplication or overwriting issues). Skip Already Processed Records Before processing, the system should: Check the Excel report/log file. Identify records that ...
I’m building an on-demand service that lets customers order groceries and medicines from neighbourhood shops straight from their Android phones. The core build I need focuses on two things: • Real-time delivery tracking so customers can watch their rider’s progress on a map, receive status updates, and get an ETA that refreshes automatically. • Seamless, secure online payment that supports major Indian cards, UPI and popular wallets, with receipts issued instantly inside the app. The flow should stay light: customers choose items from our partnered stores, pay, then follow the delivery in real time until it arrives. I will supply all product-data endpoints and the store list; you wire them into a clean Kotlin/Java codebase (no cross-platform frameworks, please) an...

Functional Requirements The platform should ideally support most of the following modules. Distributor Management Inventory and warehouse management Batch and expiry tracking Purchase and sales workflows Supplier and customer management GST/tax invoicing Credit and payment tracki...
I’m building a web-based platform that screens applicants automatically. The core workflow needs to: • parse incoming résumés/CVs, • embed both the résumé data and our job descriptions, • run a retrieval-augmented generation pipeline that compares the two, • return a clear numerical fit score so the recruiter can decide whether to proceed. All candidate data will be embedded with FAISS, while LangChain will orchestrate the retrieval and callouts to the OpenAI GPT endpoints. I already have the OpenAI key and hosting in place; what’s missing is the complete back-end logic, the scoring algorithm, and a simple front-end view that lists the ranked applicants and their matching rationale. Deliverables 1. End-to-end web applicat...
I want to push AI beyond conventional data science by weaving arcane principles into its learning loop.

I need an application that reads a multipage PDF, pulls out all the text, and then pours that content into a fresh one-page PDF that follows a custom layout I already designed. The flow is simple: open PDF → extract every text element in reading order → map each string to its assigned field or zone in my supplied template → generate a brand-new single-page PDF ready for distribution. My design file shows exact font sizes, margins, headers, and footers, so the app must respect those specifications pixel-for-pixel. Dynamic text should auto-shrink only when a block overruns its allotted space; everything else should remain fixed. No images or tables need processing—pure text only. I’m open to your preferred stack (Python with PyPDF2/PDFPlumber, Java with PDFBox, o...

I need a browser-based AI app that behaves much like but tailored to doors. The user will upload a floor plan as a single PDF; the system must automatically read the drawing, identify every door, count them, and then draw on our own product universe to suggest the most suitable models in line with the client’s stated specifications.
