Every repetitive task is a small theft of human potential. I write code that steals it back.
I'm a Python Automation Engineer and Full-Stack Developer who builds software to solve practical problems. I take an idea from requirements to a working, secure solution: designing the logic, connecting APIs and services, and shipping an interface people actually use.
I value clear communication, dependable delivery, and code that stays maintainable after I hand it over.

Most freelancers build features. I also break them before anyone else can.
- Implementation: input validation, authentication, rate limiting, secrets handling, safe payment flows
- Testing: manual and tool-assisted checks against common web vulnerabilities before delivery
- Audits: review and fixing of AI-generated ("vibe-coded") web apps that ship with hidden security holes
