Igor B.

I build production-grade data extraction pipelines and search infrastructure. Scrapers that survive Cloudflare and account-warming requirements. Elasticsearch indexes that stay fast at scale. PDF/OCR pipelines that don't break on edge cases.
Production reference: I built and operate SearchIQ — a vertical search product on Java/Angular/Elasticsearch/Redis/AWS Lambda, end-to-end mine. Most freelancers can talk about distributed search; few have shipped a search product they own.
Stack: Python (FastAPI), Node/TypeScript, Java, Playwright/Puppeteer/Selenium, residential proxy infrastructure (BrightData, Oxylabs, Zyte), Postgres, Redis, Elasticsearch, AWS Lambda, Docker.
Engagements typically start with a paid 1-2 week scoping spike for non-trivial builds, or hourly for clear-scoped consulting on existing pipelines. Available for long-running maintenance retainers after initial delivery.
