What I'm looking for

I’m looking to lead modernization of high-traffic web apps, designing secure cloud-native architectures and crafting human-centered UX with React/Next.js and AWS. I value collaborative teams, measurable performance gains, and real ownership.

Senior Software Engineer with 6+ years at PayPal (Xoom), specializing in React, Next.js, and AWS. I've led frontend modernization initiatives at global scale and built cloud-native products from scratch — including PopAuctioon, a real-time auction platform powered by AWS IVS, Cognito, and Supabase.

I hold the AWS Certified Cloud Practitioner certification and am actively pursuing the AWS Solutions Architect – Associate. My technical interests sit at the intersection of application architecture and cloud infrastructure, and I'm building toward Staff Engineer and Solutions Architect roles.

Outside of PayPal, I've contributed to React Native apps, serverless architectures with Stripe, and full-stack systems across frontend and cloud layers. Passionate about scalable design, developer experience, and human-centered engineering.
