What I'm looking for

I'm looking to build reliable full-stack products, automation systems, and backend services where I can own features end-to-end, solve scaling and rate-limit challenges, and apply my cybersecurity and OSINT background.

I've commercialized Python and Selenium web automation tools used by 150+ customers, building the dashboards, backend logic, APIs, databases, and frontend interfaces needed to run them reliably at scale.

At FlyRank, I build REST APIs and a Stripe-based usage metering and billing engine with idempotent webhook processing. I also investigate web vulnerabilities through OSINT research and build projects spanning event-driven systems, scraping pipelines, and network monitoring.
