What I'm looking for

I seek roles building scalable, cloud-native systems where I can optimize performance, mentor engineers, and deliver user-centric, accessible products with reliable deployments.

I am a Full Stack Software Engineer with 5+ years building and scaling distributed systems using Java Spring Boot, TypeScript, React, and Angular.

I have delivered 10+ back-end microservices handling high-throughput messaging and used Kafka to reduce transaction latency from 1s to under 300ms, while deploying infrastructure with Terraform and Kubernetes for consistent, reliable releases.

I led a 3-engineer team to build a greenfield TypeScript (Angular + Angular Material) application that increased operational efficiency by 3x, and replaced REST calls with GraphQL to cut query latency by 70% and reduce support tickets by 20%.

I care about performance, accessibility, and user-centric design—improving WCAG AA compliance to 92%+ and delivering frontend proofs-of-concept that shaped product direction. I enjoy mentoring engineers and collaborating across functions to deliver transparent financial and healthcare products.
