I started in Electrical Engineering before switching to Computer Science. I've always loved math, solving problems, taking on hard challenges, and building things from scratch (you can see some of them right here in this portfolio). Today I work as a full-stack developer and handle a bit of everything. I built the entire financial and audit side of a system with 120k+ users: modeling sensitive data, hardening the workflow, and integrating with payment platforms like Stripe. When needed, I optimized a problematic query, cutting response time from 2 minutes to ~300ms. If you need someone to take on your challenges and problems, reach out.
