Subject: Seeking Help Building a Real-Money Chess Feature I’m looking for experienced help adding a feature to my chess website that would allow players to compete for real money. The basic idea is to let two eligible players enter a paid chess match, with the winner receiving the prize after the platform deducts an appropriate service fee. I’d like guidance on designing and implementing the feature safely, securely, and in compliance with applicable laws. In particular, I need help understanding the legal and regulatory requirements for offering real-money chess, since rules can vary significantly depending on the player’s location and whether the activity is considered gambling, a game of skill, or something else. From a technical perspective, I would like assistance...

I need a complete blueprint for a Workforce Management system that fits a small-to-medium enterprise where every user signs in with an offline local account—no Active Directory or Azure AD in sight. Core capabilities I must see running smoothly are employee scheduling, time tracking, task management, an organisation chart, and integrated leave & roster handling. The front end has to feel equally at home in a browser on a Windows PC and inside a lightweight mobile app for iOS and Android, with a single code base if possible. Because there is no domain infrastructure, please propose a secure sign-up / sign-in flow that lives entirely inside the application (email, phone, or device-based) and outline how you will keep roles and permissions straightforward for non-technical staff...

I need a reliable, fully-automated bridge that sits between my supplier’s REST API and my online store’s REST API. The aim is to remove every manual touchpoint, so products, prices, stock levels and digital-key orders flow on their own. Here is the workflow I want to see running end-to-end: • Product side The bridge pulls the full product catalogue from the supplier, stores it locally, then pushes mapped items, prices and inventory to my store. Mapping must be preserved so future updates keep everything aligned. • Order side When a customer places an order, the bridge catches it instantly, calls the supplier API to purchase the corresponding digital key, retrieves the key and posts it straight back through the store API so the customer receives it without d...

I need a modern, fully responsive website built from the ground up. The front-end should be crafted with Bootstrap so it scales gracefully across desktop, tablet, and mobile. On the server side please use Laravel; take advantage of its routing, Eloquent ORM, and built-in security features to deliver clean, maintainable code. Core scope • Set up a relational database, create the schema, and wire it to Laravel’s models. • Implement secure authentication and role-based authorization using Laravel Sanctum or Passport. • Expose key functionality through RESTful API endpoints and document them briefly for future integration. • Apply robust error handling and input validation on both client and server. • Write concise unit and feature tests; make sure criti...

I have the core concept and a technical outline for a new medical platform that puts patients first, and now I need a full-stack developer to turn it into a production-ready application. Platform focus The entire experience must revolve around patients—everything from the landing pages to each dashboard screen should guide them effortlessly toward the information or action they need. In addition to the features outlined below, patients will be encouraged to stay engaged through an integrated blog section that delivers health tips and practice news. Stack and architecture • Back-end logic is planned in PHP for traditional server tasks and Node.js for any real-time components that benefit from non-blocking I/O. • A secure SQL database needs to be designed, populated, ...

I need a fully custom-built business website that goes beyond a simple brochure and includes core e-commerce capabilities: a secure payment gateway and an intuitive product search with robust filtering. I am not looking for a WordPress or Shopify solution—I want clean, maintainable code written from the ground up so I am free of template constraints and monthly platform fees. Key deliverables: • End-to-end design and development of a modern, responsive business site • Seamless payment gateway integration (PCI-compliant, major cards + wallets) • Fast, accurate search and filter functionality for my product catalogue • Admin dashboard where I can add or edit products, prices, and inventory • Deployment to my hosting environment with basic docum...

Key Requirements: - Case history tracking: Document and retrieve details on cases each expert has worked on. - Access restricted to company employees. Ideal Skills and Experience: - Database design and development - Experience with secure access controls - Familiarity with case management systems

I need a straightforward system that lets us follow every 5-gallon / 20 L bottle from the moment it leaves our factory until it comes back again. Each container already carries a permanent QR code such as “BTL-000127”, so the job is to capture those scans and turn them into clear, actionable data. Scope of work • Web dashboard – a browser-based control centre where I can see, at a glance, where every bottle is, which customer it is linked to, its full scan history, and any units that are overdue, lost, or marked damaged. • Mobile application – the drivers’ tool for scanning and assigning bottles while they are on the road. This must run on both iOS and Android, work with the phone’s camera QR reader, and allow quick offline capture that sy...

I need to organise all of my customer information in a structured SQL database and give my team a simple way to add or update those records directly from their phones. The core of the job is two-fold: first, design and deploy a clean relational schema that captures names, contacts, addresses, notes and whatever other standard customer fields you would normally expect; second, build a mobile interface that lets users create, read, update and delete those records through straightforward forms. The mobile side can be cross-platform in Flutter or React Native, or native Android if that is faster for you—what matters most is that it connects securely to the database, validates input, and presents a searchable list of existing customers. No CSV imports or external APIs this time; everythi...

Acceptable: STC Cloud, SCCC Alibaba Cloud, Google Cloud Dammam, Oracle Riyadh. Bids proposing hosting outside KSA will be rejected without review. Platform architecture — two layers 1. Tenant application — the workspace each client company uses, fully isolated 2. Owner console — our internal layer for client provisioning, plan management, entitlements and revenue Scope — 50+ modules a...

I need a full-scale hotel management platform, but the very first milestone has to be a rock-solid Reservation System that guests can use end-to-end online. Visitors must be able to check real-time room availability, create a booking, receive instant confirmation, and manage their stay dates from any device. On the back end I want a clean dashboard where staff can see incoming reservations, apply rate rules, block rooms, and override allocations without delays. Online Booking is the only feature that must ship in this phase; modules such as Billing & Payment or broader Inventory Management can wait until the reservation flow is proven in production, yet the architecture should leave room for those add-ons. A responsive web interface, secure database design, role-based access, and succ...

We are looking for an experienced n8n automation developer / automation engineer to complete, debug, configure, secure, and production-test an existing AI-powered business automation system. The system is already built as a collection of n8n workflows. The goal is NOT to rebuild everything from scratch unless technically necessary. IMPORTANT: Existing working functions must NOT be removed or replaced without approval. The developer must first review the complete existing system, document all workflows and functions, and then improve it without losing existing functionality. CURRENT / REQUIRED FUNCTIONS: • AI Lead Qualification • Lead Processing and Routing • Recruiting & Candidate Analysis • Media Analysis • Customer Review Analysis • AI Content Gener...

I need a complete slot-style casino game that players can enjoy in their browsers or in a dedicated mobile-ready build, plus a secure back-office where I can run every aspect of the operation. Gameplay • Smooth, modern slot mechanics with engaging graphics, sound, and a provably fair or RNG-certified engine. • All core player actions—spin, stake selection, auto-play, win animations—must be fluid and performant across devices. Admin & Analytics The back-office is just as important as the game itself. From one panel I have to: 1. Create, edit, suspend, or delete player accounts (user management). 2. View real-time and historical game statistics—RTP, turnover, active users, hit frequency, top wins, etc. 3. Credit and debit balances, approve withdr...

I have a production oracle instance that has grown beyond 100 GB and it now needs to live on SQL ,Server postgres sql . The task covers everything from preparing the source, mapping the schema, transferring the data, and validating that every object—tables, views, functions, and constraints—behaves exactly the same once it lands in SQL Server. Here is what I expect to walk away with: • A fully migrated SQL Server database, ready for cut-over • A repeatable migration script or SSIS/ADF/DMS pipeline so I can re-run the process for future refreshes • A concise migration report highlighting any datatype conversions, performance tweaks, and objects that required special handling • Verification scripts or queries that prove row counts, checksums, and refe...

Our Oracle E-Business Suite instance and its core databases are straining under heavy loads, and I need an experienced hand to restore peak performance. The assignment centers on performance tuning, specifically: • Query optimisation – analysing execution plans, AWR/ASH reports and SQL traces to cut response times and CPU usage. • Index management – auditing existing structures, redesigning or rebuilding where needed, and advising on partitioning or compression if it brings measurable gain. I will grant full access to the non-production environments first, then schedule controlled moves into production once we agree on the changes. Clear before-and-after metrics are essential; please include a concise report that shows what you changed, why, and the improvemen...

I need to take Dukandar a step further by giving my store managers and cashiers true real-time visibility into inventory. The single focus is improving inventory tracking, and within that, delivering live stock updates. Every update must show two things side by side: the exact current stock level for each SKU and the most recent sales history that caused the change. Supplier information can stay out of scope. Your solution has to work in an offline-first retail environment—our shops lose connectivity at times—so local writes must sync automatically once the network is back. Whether you prefer Node, Laravel, Python, Firebase, Flutter, React, or something similar, the code must be well documented and production-ready. Clean database design, efficient change listeners, and a push...
