What I'm looking for

I’m looking for a hands-on engineering role building user-facing products and reliable backend systems, with collaborative teams, strong testing practices, and opportunities to improve performance and automation.

I am a full-stack developer with experience building scalable web applications and DevOps-aware deployments for enterprise and healthcare clients. I’ve shipped features used by hundreds of advisors and hundreds of thousands of members, and I prioritize test coverage, reliability, and measurable performance improvements.

My background blends software engineering coursework with hands-on internships where I implemented Redux Saga flows, automated billing with Stripe, built JSON-driven form builders, and developed Celery workers to remove API bottlenecks. I lead code reviews, maintain high test coverage, and collaborate closely with product and design teams to create reusable component libraries.

I focus on delivering tangible impact: reducing manual calculation time by 97%, accelerating feature delivery by 20%, improving system response time by 20%, and streamlining onboarding and development time across projects. I seek roles where I can continue building robust systems and user-focused products.
