What I'm looking for

I’m an immediate joiner looking for opportunities to lead projects, modernize frontends, and innovate in fast-paced tech environments—building reliable, real-time fintech experiences while mentoring engineers and collaborating closely with product and backend teams.

I’m a Senior Software Engineer with 7+ years of experience building data-intensive, high-performance web applications across fintech and enterprise platforms. I primarily work in React and Next.js, with deep Angular expertise from large-scale payment and financial dashboard products, and I’m known for delivering real-time payment dashboards, data-driven interfaces, and scalable UI architectures in mission-critical systems.

I’ve led frontend migrations, mentored engineers, and collaborated across product, design, and backend teams in Agile environments. In recent consulting work, I built serverless full-stack applications with Next.js, Angular, FastAPI, and Supabase—shipping real-time crypto analytics and reminder experiences with secure authentication (Cognito, NextAuth) and modular backend integrations. Earlier roles included Angular migrations (7→12+), performance improvements (lazy loading and modular refactoring), and real-time mission-critical features using WebSockets.
