What I'm looking for

I want to build scalable web and API products with modern JavaScript, ownership of performance and CI/CD, and strong testing. I’m excited to grow in dynamic teams by delivering reliable microservices and secure user experiences.

I’m a Full-Stack Engineer with 3+ years of experience specializing in web development and modern JavaScript technologies. I build scalable web applications with React, Express.js, and MongoDB, and I’ve improved application performance by up to 60% while reducing deployment times by 40%.

I thrive across front-end UX optimization and back-end API development, designing reliable systems and developer-friendly workflows. In a microservices role, I helped deliver a scalable 6-service architecture, integrated real-time commit testing, and deployed Prometheus/Grafana monitoring—cutting incident response from 30 minutes to under 5 minutes.

I also focus on quality and security, delivering robust testing and hardened authentication flows. From achieving 99.9% uptime in a ticketing microservices platform to reducing login times by 50% and unauthorized access by 65% with OAuth and email verification, I’m eager to contribute to and grow within dynamic teams.
