Data Mining Jobs

I have worked on multiple AI data generation and model evaluation projects involving both Supervised Fine-Tuning (SFT) and Reinforcement Learning from Human Feedback (RLHF). My work included designing high-quality prompts, analyzing model responses, identifying reasoning and factual errors, and creating golden responses that served as the expected reference outputs. I worked extensively with repository-based tasks using Cursor, where I understood large codebases, executed run scripts, analyzed parse scripts, and validated both Pass-to-Pass (P2P) and Fail-to-Pass (F2P) test cases to ensure the generated solutions were functionally correct. I also reviewed code quality, verified outputs against expected behavior, and ensured compatibility with existing repositories. For tool-use and agenti...

I need a real-time data pipeline that ingests tick-by-tick football information from the Betfair API for each match taking place in the top five European leagues (Premier League, La Liga, Serie A, Bundesliga, Ligue 1). The feed must rely exclusively on this API—no scraping—so skill with Betfair’s Streaming or Historical service is essential. The stream should enrich every tick with contextual match metadata and persist it in an easily queryable store (PostgreSQL, parquet on S3, or a solution you propose). Low-latency processing is critical; sub-second lag from the API to storage is my target. I plan to run the pipeline on AWS, so please factor in services such as Kinesis, Lambda, Fargate or similar if they fit the design. Deliverables • Codebase (Python preferred...

I need a lean MVP that automatically hunts for conversations where my web app can be mentioned in a helpful, brand-building way. The workflow is straightforward: 1. Crawler • Scan Reddit plus Google News (blogs and articles surfaced). • Harvest threads and comments. 2. AI Scoring • Rank each conversation primarily on its relevance to the app and the overall popularity of the post or thread. • Ignore low-signal chatter; keep only high-potential mentions. 3. Drafting Replies • Use an LLM to generate a concise, promotional reply that feels organic and value-adding, not spammy. 4. Dashboard Review • Queue the top-scoring replies in a simple web dashboard. • I must be able to edit any draft before it goes live and q...

I’m organizing a 10-day, full-day Java Data Structures & Algorithms program in Chennai from 20 July to 30 July and need a trainer who can be on-site for the entire duration. Here’s what I’m after: • Content scope: please be ready to teach both basic concepts (arrays, stacks, queues, linked lists, trees, graphs, sorting/searching fundamentals) and advanced algorithms (dynamic programming, graph algorithms, greedy techniques, complexity analysis, etc.). • Mode: the sessions are strictly in-person; interaction and live problem-solving are key. • Experience level: an intermediate profile is ideal—someone confident enough to explain concepts clearly yet relatable to participants who may still be grasping the fundamentals. Trainers, freelancers...

I need help pulling strictly numerical data from a handful of online databases and entering it into a spreadsheet template I will supply. Everything you collect will come directly from those databases—no PDFs, scans, or web-scraping from regular sites—so the task is about careful extraction, accurate transcription, and a quick cross-check rather than guessing or reformatting text. You will log in, locate the specified tables or dashboards, copy the required figures (row by row), and paste them into the correct columns of my Excel/Google Sheets file. A few fields may require you to apply the database’s built-in filters or basic calculations before recording the result, but there is no heavy analysis involved.

I need a clear-cut market area analysis centred exclusively on customer demographics, with income levels as the key metric. The purpose is to define the real-world catchment zone around my retail site, quantify its buying power, and visualise that data on an easily shareable map and concise slide deck.

I already have a starter sheet with 300 Instagram profiles; I now need that list grown to 1,000 solid contacts. The focus is very specific: female models or single women aged 30–50 who live and work in the greater-DC, Northern Virginia, and Southern Maryland area (the DMV). I will share a few sample profiles so you can see the exact vibe and quality I’m after. Your search must stay on Instagram for this first phase and favour accounts that show real, active engagement on recent posts—empty-like or bot-driven pages won’t make the cut. When you find a match, add her details to the existing Google Sheet so everything stays in one place. Deliverables (Phase 1) • Google Sheet expanded from 300 to 1,000 entries • Columns: I will provide If the list mee...

I have a collection of unstructured data that needs to be mined and modelled in R so I can reliably forecast future trends hidden inside it.

The work centres on: • Ingesting and preprocessing raw, unstructured text or mixed-format inputs. • Applying appropriate R packages (tidyverse, text mining suites, caret, or any other you feel is best) to transform the data into an analysable structure. • Building and evaluating predictive models that reveal upcoming patterns or shifts I can act on. • Supplying reproducible R scripts/notebooks, c...

I need a meticulous pair of eyes—and hands—to bring together data from more than ten Excel sheets into one master workbook I will provide. Each source sheet carries a mix of plain text and live formulas, so every entry must be pasted or re-typed exactly as it appears, without disturbing any existing calculations. The template you’ll receive shows the precise column order. Simply populate it, keep all spacing, spelling, and capitalization intact, then run a full sweep for duplicates: flag them clearly, confirm counts with me, and remove any I approve for deletion. Nothing should be lost or unintentionally altered; a single stray character compromises our internal search results. When the import is complete, send me: • The updated master workbook, formulas functionin...
