Automation, web scraping, and AI solutions for business

10 years of hands-on freelance delivery. I take a task from requirements to a tested launch: clarify the outcome, propose the simplest reliable architecture, build it, verify it, and provide clear handover instructions.

What I can build:

• web scrapers for websites, marketplaces, and catalogs with CSV, Excel, JSON, or database output;
• browser automation with Playwright and Browser Automation Studio: authentication, forms, report downloads, and repetitive workflows;
• Telegram bots and monitoring for prices, stock, and events;
• REST API and webhook integrations using FastAPI, PostgreSQL, Supabase, and external services;
• practical AI features, RAG search over a knowledge base, content generation and validation;
• Playwright end-to-end tests, QA audits, and stabilization of unreliable flows.

I work with difficult data sources: JavaScript-heavy pages, authentication, rate limits, proxies, anti-bot protection, and undocumented APIs. If a platform restriction makes a solution unreliable, I explain it before the project starts.

Selected delivery examples:

• a public media-center plugin with 50+ releases, unit tests, and Playwright e2e coverage;
• a RAG Telegram bot using Gemini embeddings, FAISS, hybrid search, and daily knowledge-base updates;
• an AI platform for batch processing marketplace product content;
• price and promotion monitoring, marketplace analytics, and Telegram alerts;
• full-stack services built with FastAPI/Node.js, React/Next.js, and PostgreSQL.

What you receive: a working result tested on real data, error logging where needed, setup instructions, and an honest estimate before work begins.

I do not take projects involving fake engagement, mass account creation, or abuse of third-party platforms.
