What I'm looking for

I’m looking for a team where I can build scalable SaaS products end-to-end—shipping high-performance features, clean UI/UX, and dependable systems—while collaborating closely with product and design to improve user outcomes.

I’m a Full Stack Engineer with 4+ years of experience building scalable SaaS platforms and web applications, focused on clean UI/UX, scalable architecture, and reliable user experiences. I’ve led end-to-end development across multi-tenant environments, delivering performance improvements, better navigation, and robust workflows.

At Sponsorvista, I architected backend APIs for sponsorship operations, billing, reporting, permissions, and collaboration—while delivering Stripe subscription infrastructure and strengthening reliability through telemetry, API error tracking, automated testing, and Web Vitals monitoring. At Compfeed, I built and optimized Next.js + React frontend experiences for AI-powered design tools, shipped LangChain + OpenAI features, and implemented ticket automation that cut manual triaging by 40%. I also bring a product-minded engineering approach from earlier roles scaling to 10k+ users and supporting design-to-development feasibility, reducing revisions by 30%.
