About Me

I am a Principal Software Engineer with a deep passion for building robust, scalable backend systems. I specialize in Node.js frameworks like Express and Fastify, as well as Laravel, and I have extensive experience migrating legacy platforms to modern microservices architectures.

Throughout my career, I've had the opportunity to lead and mentor engineering teams across the entire application lifecycle. At companies like Bykea and Canary7, I drove significant improvements in system latency by optimizing complex database queries across PostgreSQL, MongoDB, and Redis.

My focus is always on engineering excellence—whether that means implementing automated CI/CD pipelines, optimizing message broker communications with RabbitMQ, or fostering a collaborative environment through rigorous code reviews and architectural planning.
