I build scalable cloud and event-driven systems that improve performance, reliability, and delivery outcomes.

At Sysco LABS, I've led the recovery of a delayed delivery team, taking it to successful UAT and production ahead of the committed timeline while owning architecture, code reviews, and offshore delivery coordination.

I've built full-stack and event-driven systems on AWS, including Next.js applications, asynchronous Python workers, and multi-topic Kafka consumers using Java Spring Boot. I also designed a multi-region active-active disaster recovery setup using AWS ECS, RDS, Route53, and Lambda to support 99.99% uptime.

Previously, I reduced API latency by 99.5%, from over four seconds to under 20ms, by re-architecting a tightly coupled monolith into an event-driven AWS architecture. I'm also researching workload-aware database sharding and building an AI-filtered content aggregation platform.
