What I'm looking for

I’m looking to lead backend and full-stack engineering on security-first, high-performance platforms—owning architecture to production, improving reliability and latency, and mentoring teams through code review and CI/CD.

I’m a software engineer with 7+ years architecting, building, and scaling high-traffic, mission-critical systems across FinTech, healthcare, education, and e-commerce. I focus on backend APIs, security, and performance—shipping solutions that stay reliable under real-world load.

I’ve delivered sub-50 ms latency for RESTful APIs, designed platforms for 100,000+ concurrent users, and contributed to tenfold database performance improvements. In leadership roles, I’ve owned architecture through production operations, including authentication, billing and payments integration, usage monitoring, and security.

As Lead Software Engineer & Technology Lead, I instituted a rigorous code-review process and CI/CD pipeline (GitHub Actions), reducing production bugs by 40% post-deployment. I also prototyped a Go service that delivered a 200% performance gain over a previous Python implementation, helping guide the team’s roadmap.

I also bring strong product ownership as a founder and lead engineer—scaling an educational platform from concept to 50,000+ registered users with 99.9% uptime, and integrating payments that processed 20,000+ transactions in the first year. My professional ethos is hands-on technical leadership: mentoring engineers, building for scale, and continuously improving both systems and teams.
