What I'm looking for

I am looking for a role that fosters innovation, values clean architecture, and offers opportunities for technical leadership.

I am a passionate Full Stack Developer with over a decade of experience in building fast, scalable, and reliable web applications. My expertise lies in JavaScript, TypeScript, React, and Node.js, complemented by strong backend knowledge in MongoDB, Redis, and cloud services like AWS. I thrive in collaborative environments, working closely with cross-functional teams to transform complex technical challenges into simple, scalable solutions.

Throughout my career, I have successfully modernized systems, reduced server costs, and optimized performance for real-world businesses. My recent role at the U.S. Environmental Protection Agency involved a significant overhaul of legacy systems, where I implemented a modular backend architecture and a smart caching strategy that improved performance and response consistency. I am currently seeking opportunities to bring startup-style innovation and technical leadership into ambitious new projects.
