I build small, precise tools and the backends behind them.
Backend developer working in Python, Go and JavaScript. Mostly automation, scraping at awkward scale, and utilities I got tired of not having.

Selected work
-
Captcha solver library One interface over 2Captcha, Capmonster and Anticaptcha, so switching provider mid-incident is a config change rather than a rewrite.
-
Checkout & raffle automation Sneaker and collectable releases. The hard part was never the request, it was staying plausible under rate limits.
-
Deals verification platform Email validation, live support and an API that keeps working when the upstream feed does not.
-
This site's tool suite Twelve utilities, no framework, no dependencies, no tracking. Everything runs in your browser.
