I build custom web scraping systems in Python for JavaScript-heavy sites, browser automation flows, login-protected pages, and recurring data collection pipelines. If you need clean structured data delivered from a website into CSV, Excel, Google Sheets, APIs, or a database, I can build the scraper and the surrounding workflow. What I can help with: - Web scraping and data extraction - Python scrapers for dynamic websites - Selenium and browser automation - Reverse engineering XHR / network requests - Anti-bot aware scraping workflows - Scheduled scraping pipelines - Data cleanup, normalization, and delivery I work on both one-off scraping jobs and long-running scraping systems. My focus is reliability, maintainability, and clean output rather than fragile scripts that break after a small site change. Common use cases: - Lead and business directory scraping - E-commerce product and pricing scraping - Real estate and listing scraping - Report download automation - Internal dashboard and dataset generation Tech I use when appropriate: Python, Selenium, Playwright, requests, aiohttp, BeautifulSoup, lxml, browser automation, APIs, Docker If you have a target site and sample output format, send it over and I can tell you the best scraping approach.

Last 2 years I've been working as a Mac OS X developer. I have over 10 years of experience in developing SQL-reports, VBA. I've completed more than 600 Excel VBA projects on Upwork and Elance. I graduated from university majoring in Applied Mathematics. I am looking for challenging tasks, not copying existing solutions.

I build and ship production React Native apps — and the full backend and AI systems behind them. My flagship app, NotePal, is live on Google Play: an AI study tool that turns audio, PDFs, YouTube links, and text into notes, quizzes, and flashcards. One FastAPI backend powers both the React Native mobile app and the web app, with cross-platform subscriptions handled through RevenueCat (mobile) and Stripe (web). It's a real, monetized product in a store — not a demo. That's the difference I bring: I don't just build the screens, I ship the whole thing — store submission, in-app purchases, billing webhooks, and the scalable backend that keeps it running cheaply at volume. What I build: - Cross-platform mobile apps (React Native — Android & iOS), including store submission and in-app purchases (RevenueCat) - AI-powered apps (OpenAI, Claude, RAG pipelines, vector search with Pinecone) - SaaS platforms — multi-tenant architecture, auth, billing, dashboards - Full-stack web apps (Next.js, React, TypeScript, FastAPI, Node.js) - Backend & cloud infrastructure (AWS Lambda, SQS, Fargate, Docker, CI/CD) Recent work: - Built NotePal end-to-end — React Native app + web + AI backend — offloading heavy work (PDF/YouTube/long-audio processing) to serverless Lambdas to keep cloud costs low - Built GeoScraper, a B2B SaaS with a credit-based billing engine handling concurrent, race-condition-safe transactions - Lead full-stack development and DevOps on a HIPAA-compliant healthcare platform — encryption, RBAC, audit logging, CI/CD, and production reliability I'm a strong fit if you're: - Launching a mobile app and need it built, monetized, and shipped to the stores - Building an AI or SaaS product and want it production-ready, not a fragile prototype - Scaling an existing app without a costly rewrite Send me a message with what you're building. I'll reply with an honest technical assessment and the fastest path to shipping it.
