I’m a scraping & automation engineer with 8 years of experience building reliable data pipelines for complex websites. My focus is reverse-engineering and anti-bot adaptation—making scrapers resilient when sites change quickly, add dynamic rendering, or tighten protections.

• Web reverse engineering: tracing data flows, understanding client-side logic, and restoring stable extraction paths
• AST / code analysis: parsing and reasoning about obfuscated or generated scripts when needed
• CAPTCHA handling (where permitted): integrating practical solving workflows without turning runs into fragile hacks
• TLS fingerprinting awareness (e.g., JA3): aligning HTTP clients and proxy setups to reduce blocking and improve consistency

Comfortable shipping production Actors in Python and Node.js, with an emphasis on maintainability, observability, and clean structured outputs on Apify.

I prioritize stability, observability, and fast iteration—clear inputs/outputs, predictable retries, and logs that help you debug real issues without guessing.

Note: I only work on projects that comply with applicable laws and each platform’s terms of service.
