What I'm looking for

I want to build mission-critical, high-impact products—modernizing complex systems, improving performance, and strengthening reliability. I’m eager to lead technical foundations in the commercial vehicle industry using cloud-native architectures and disciplined delivery.

I’m a Senior Full Stack Engineer with 9+ years of experience architecting and delivering scalable web applications. I specialize in modernizing legacy systems in Agile/Scrum teams and setting coding standards that help delivery move faster and stay reliable.

At Crate & Barrel, I architected and led the migration of a legacy e-commerce monolith to microservices on AWS, reducing deployment time by 40%. I delivered a high-performance GraphQL API layer that cut page load times by 25%, built real-time inventory tracking to reduce data latency from 5 minutes to 2 seconds, and implemented test automation (Jest and Cypress) to reach 95% code coverage on critical paths.

Previously, at Confluent and Visa, I built high-throughput data streaming infrastructure and enterprise-grade payment systems while strengthening operational excellence through monitoring, incident response, and performance tuning. I’m passionate about building mission-critical software that drives business impact—and I’m ready to lay the technical foundation for high-impact projects in the commercial vehicle industry.
