I build backend systems that don't break under pressure. My work handles 10M+ monthly users at Freecash.com — and I've shipped everything from real-time trading platforms to fraud prevention systems with 0% fraud rate.
Specialized in NestJS, PostgreSQL optimization, and high-performance Node.js architectures. I prefer long-term collaborations where I can own the technical decisions and deliver clean, maintainable code.

You need data. Lots of it. I get data. Lots of it.
Tired of CTRL+C, CTRL+V? Me too. That's why I build bots to do it for me – way better. I basically lived and breathed b2bhint.com for 5 years, building 500+ scrapers, wrangling a 1TB+ database of 200M+ companies, and juggling everything from backend to Elasticsearch. If it had data, I scraped it.
Then, for a cool 2 years at artmetadata.io, I did it all again for 10M+ art lots with 50+ scrapers, plus built their internal dashboard because, why not? Oh, and there are 50+ smaller projects where I've played data superhero for various clients.
Bottom line: If there's data on the web, I can probably get it. And I'll build the system to manage it. Let's talk.
