Exclusiv pentru developeri din Romania. Detinem un magazin online de anvelope si dorim crearea unui modul de import produse din diverse feeduri xml, csv sau aproximativ 20 de feeduri diferite, de la diversi furnizori, toate difera deci va fi vorba de mapare corecta. In urma importului as vrea sa ramana in baza de date numele furnizorului de la care s-a adaugat produsul. Toate produsele vor fi adaugate pe baza Ean-ului care este unic incat sa evitam dublarea produselor in baza de date proprie. As vrea sa facem un sistem care stie sa citeasca cel mai bun pret de la acesti 20 de furnizori si de acolo sa afisam produsul in magazin-deci furnizorul va fi dinamic, se va tot schimba in functie de bestprice feed. De asemenea as vrea sa rulam update-uri de stoc/pret periodice (cron). Sistemul va...

...in the Matlab simulation environment. Consider a MIMO system in a configuration with 2 transmitting antennas and 2 receiving antennas (2x2) MIMO) when a random string of bits will be transmitted, with and without the V-BLAST detection algorithm implemented. The performance of the proposed system will be tested through scenarios in which the number of active users at a given time in the network will vary, different modulation techniques will be used (BPSK, QPSK) when the channel is affected by different types of fading (Rayleigh, Rice ) and Code Division Multiple Access (CDMA) using real spread codes (Walsh-Hadamard and PN). Different types of equalizers will be implemented at the reception. The evaluation of the performance of the system in question will be performe...
called automatic labeling of reviews with Clustering, it can be done by automatic labeling of texts, you should have a set of reviews labeled positively / negatively and then run an automatic classifier that learns from these labels after to run such of the classifier you must first "clean" the text, remove all words without content, figure out what words you have left (bring them to the dictionary form) and then see if based on the remaining words the classifier can determine the class of your review: poz or neg .... with a small interface. Python has these clarifiers in English ... romanian: Se numește etichetarea automata a recenziilor cu Clustering, se poate face prin etichetarea automata a textelor, tu ar trebui sa ai un set de recenzii etichetate pozitiv/negativ si apoi s...

I need help bringing a raw inventory CSV into a clean, well-structured Excel workbook that my team can expand and report on. The focus is solid data organisation first, with some light analysis tools added so anyone in the warehouse can slice the figures later. Here’s what I’d like delivered: • Import the supplied comma-separated file and convert it into a properly formatted Excel Table. • Resize the table so all active rows and columns are included, then give it a clear, descriptive name that makes future formulas easy to read. • Build an Advanced Filter that lets us pull subsets (e.g., by location or stock level) without copying the whole sheet around. • Add a multi-level sort (think category → sub-category → SKU) so items appear i...
I have a raw CSV that needs to become a streamlined analysis workbook. The goal is to bring the data into Excel, shape it into a named table, and layer on the tools I use most—Advanced Filters, Conditional Formatting, and PivotTables—so I can slice, summarise, and visualise the information quickly. Here’s the flow I want to see inside the final file: • Import the CSV and convert it to a properly sized, named table. • Build an Advanced Filter (criteria on a separate sheet) so I can isolate records by multiple fields. • Apply a multi-level sort to any filtered view to keep results in logical order. • Add conditional formatting that highlights key exceptions or trends; rules should be easy for me to adjust later. • Demonstrate conver...
...the Entra admin portal (and, if useful, PowerShell and/or the Teams Admin Center) to trace the Teams sign-in flow, identify the misconfiguration, and apply the fix so the Teams desktop client launches and signs in normally again. You’ll receive admin access to the tenant and access to a test device where the tenant has been installed and the issue can be reproduced. Deliverables Root-cause analysis of the Teams desktop startup failure. Configuration change(s) applied in Entra ID and/or Teams that resolve the error. A brief hand-off note summarizing what was changed and why. Acceptance criteria Microsoft Teams desktop launches and signs in successfully on the test account without errors. No other tenant services or Microsoft 365 applications are disrupted by the fix....
My Shopify store is driving steady, qualified traffic through ads and social channels, yet sales stall once visitors reach the site. I need a seasoned conversion-rate optimisation speciali...Evidence: analytics screenshots, session-recording snippets, or other data that supports your findings. • Clear, actionable explanations of why each issue hurts conversions and what to fix first (no broad marketing advice—this is a diagnosis, not campaign management). This engagement ends once I have a crystal-clear picture of what’s stopping customers from completing their purchase. If your analysis proves accurate, we can discuss an implementation phase later; for now I only need the diagnostic. Final notice I have one arder at all so no technical problem with the websit...

I have a data-analysis pipeline that relies on a steady flow of fresh product images from a well-known e-commerce site. What I need is a robust scraper that can navigate the catalog, collect every product’s main and variant images, and deliver them to me neatly organized. Key points you should know: • Target: a single e-commerce platform (URL supplied after award). • Payload: high-resolution image files plus a CSV/JSON map linking each file to product ID, title, price, and category text that you extract during the same run. • Scale: thousands of products per crawl; a resumable approach is essential so partial failures don’t force a full restart. • Frequency: I’ll trigger the crawl weekly, so reusable code is a must. I’m happy wit...
...ASHRAE 62.1 ventilation rates and demonstrates compliance with the local energy code. 3. All equipment and duct sizes clearly labeled and referenced so my installer can quote without extra field redesign.

Let me know your usual turnaround time and which software you prefer for load analysis (Manual J, HAP, TRACE 700, etc.)....
...weaknesses before launch, demonstrate real-world exploitability, and give me a clear, prioritized plan for remediation. Scope • Full application security testing: authentication, authorization logic, input validation, business-logic flows, session management, server configuration, and third-party integrations. • Black-box techniques are fine, but I can supply test credentials for deeper analysis if that helps you reach code paths hidden behind login. • Industry-standard tooling such as Burp Suite, OWASP ZAP, Nikto, or your preferred commercial scanner is expected, followed by manual verification so I’m not just getting automated false positives. Deliverables (acceptance criteria) 1. A concise executive summary highlighting critical findings in p...
...ready-to-go .3mf file that slices cleanly and prints reliably in PLA. The finished piece must sit in the medium size range—somewhere between 10 cm and 30 cm on its longest side—so please choose layer heights, infill, supports, and any adaptive settings with that envelope in mind. You are free to optimize within Bambu Studio’s tool-set, but the final file has to open with no errors, pass the built-in analysis, and be fully configured for PLA (standard 0.4 mm nozzle). If you feel multiple profiles will help, include them inside the same project file. I have a base file you can work off of, but I need it tweaked for a specific buyer which has requirements of 34.90mm coin and 6.51mm width. Box would need to fit 5 coins each and have a slot for each coin for retent...
...faster. To do that, I need a partner who understands the nuances of the UAE marketplace and can take full ownership of three core areas: product selection, listing optimisation, and sales-growth strategy. Product selection comes first. I already have a short list of ideas, but I expect you to validate each one and complement it with data-backed suggestions of your own. Full market research—demand analysis, competitor mapping, keyword depth, fee impact, and profit projections—must accompany every recommendation. Once products are approved, listings should be created or refined for maximum visibility. Titles, bullets, back-end keywords, imagery, and A+ Content must be optimised in both English and Arabic to secure indexing and conversions from day one. Finally, I wan...

I have a collection of text-only PDF files that must be converted into clean, fully editable documents so I can apply uniform headings, fonts, and spacing later on. Each page has straightforward paragraphs—no complex tables or heavy numerical data—so the job is all about accurate re-typing and tidy layout rather than data analysis. What I need from you is simple but exacting: replicate every word from the PDFs, preserve basic paragraph breaks, and return the content in an editable format (Word or Google Docs is fine). Spelling, punctuation, and line order must stay true to the source, yet the final file should look neat enough that I can jump straight into document formatting without extra cleanup. Deliverables • A separate editable document for each original PD...

...yet I want a fresh perspective on exploratory analysis, pattern discovery, and interpretation so the insights are both rigorous and clearly actionable. The core task is straightforward: ingest the raw text files I provide, clean and structure them appropriately, then run exploratory and statistical analyses that reveal key themes, sentiment trends, and any significant correlations you uncover. Feel free to use Python with pandas, NumPy, NLTK, spaCy, or other standard NLP and data-analysis libraries—whatever you are most comfortable with as long as the workflow is reproducible. Because I don’t have a hard deadline, quality and clarity matter more than speed. You will deliver: • Well-commented notebooks or scripts that walk through each analysis st...
I’m working on a macroeconomics assignment that focuses exclusively on fiscal policy. I need a concise, academically sound research and analysis piece that explains how government spending and taxation choices influence overall economic performance. Your job is to gather the latest scholarly and policy-based sources, identify key fiscal measures, and evaluate their short- and long-term macroeconomic effects. Clear arguments, well-interpreted data trends, and correct citation style are all essential. Deliverables • 2,000–2,500-word report in editable format • Minimum 8 reputable references (journals, IMF/World Bank, or comparable) • Supporting charts or tables that illustrate core findings • Brief executive summary (≈250 words) that h...
...not required for this engagement. Please turn the findings into clear, compelling way that I can drop straight into: • a live sales demo • case-study collateral • internal roadmap discussions I also want to see how results vary by conversion-time buckets (fast vs medium vs slow closes) so that dimension should be reflected in the visuals.

Primary Question to Answer: What measurably changed after the new sales workflow platform was adopted? Provide 5&...
I’m pulling together several small research datasets and need one reliable person who can do two things equally well. First, you’ll take the raw numbers I supply, enter them with perfect accuracy into my Google Sheets template, double-checking formulas as you go. This is classic spreadsheet data entry: clear headings, no stray spaces, every cell formatted correctly for later analysis. Once each sheet is complete, you’ll switch hats and write a brief, engaging summary (≈250 words) that explains what the data shows in plain English. Think of it as a mini blog post that highlights key findings and any surprising trends—concise, reader-friendly, and free of jargon. Because the project combines freelance writing and spreadsheet data entry, I’m ...
I have a backlog of information that must be transferred quickly and accurately into an online database. The task is strictly data entry—no analysis or design work—so your attention to detail and consistency are what matter most. Here’s what the job involves: • Receive raw worksheets, PDFs, or scanned notes from me. • Enter each record into the designated fields of the database interface I provide. • Double-check for typos, duplicate records, and missing values before submitting. Although my main focus is database entry, if you feel comfortable with light spreadsheet clean-up or transcription, let me know—I may have additional work later. Deliverable: a fully populated database table that matches my source files 100 % in content and ...

I’m sitting on a few spreadsheets filled with raw numbers that need to be turned into a clean, analysis-ready workbook. Everything lives in Microsoft Excel, so all cleaning and re-formatting must happen there—no exporting to other tools. Here’s what I need: • Strip out duplicates, stray characters, and blank rows. • Standardise number formats (decimal points, currency symbols, thousand separators) so every column reads consistently. • Re-calculate or flag totals where formulas were broken during data collection. • Hand back a single, well-structured .xlsx file plus a short “change log” sheet noting the main fixes. I’ll provide the original file as soon as we start. If you’re comfortable using Excel functions such ...
