About Me

Building systems that scale

I'm a software developer who thrives at the intersection of backend engineering and cloud infrastructure. Over the past 3+ years, I've worked across startups and enterprise organizations, tackling problems that range from migrating legacy COBOL systems to building event-driven architectures on AWS.

What drives me is the challenge of making systems resilient and performant at scale. Whether it's designing dead letter queues to achieve zero data loss, optimizing database queries to shave 80% off response times, or building batch processing pipelines that crunch 200,000 data points in under 3 minutes — I care about the details that make production systems reliable.

Currently at Quest Global, I'm engineering enterprise-grade workflow systems using Python, FastAPI, and React.js, with a focus on distributed messaging, database performance, and infrastructure automation.
