What I'm looking for

I’m looking for a team where I can lead engineering and deliver end-to-end features—modernizing legacy systems into scalable platforms—while maintaining clean code, test-driven development, and strong CI/CD practices.

I’m a seasoned software engineer with over 10 years architecting, developing, and deploying production-grade applications across Fintech, Ecommerce, Healthcare, and SaaS. I’m a strong advocate for clean code, test-driven development, and continuous integration practices.

I’ve led teams and mentored junior engineers while modernizing legacy systems into scalable, high-performance solutions. In ecommerce and embedded fintech work, I delivered a unified React/Node microservices platform handling 10,000+ monthly transactions, built a Stripe payment ecosystem (one-time, recurring, and BNPL), and reduced initial page load time by 40%.

I also drive measurable engineering outcomes through performance and reliability improvements—migrating 70% of a JavaScript codebase to TypeScript, improving query latency from 450ms to 85ms, and increasing test coverage from 45% to 78%. In healthcare, I designed HIPAA-compliant RESTful APIs with AES-256 encryption and RBAC, and integrated Sentry and ELK to reduce MTTD from 4 hours to 15 minutes.
