What I'm looking for

I seek a hands-on engineering role where I can build scalable web products, lead small teams, work with React/Node/Python on AWS, and contribute to product strategy.

I am a full-stack software developer with 2+ years of hands-on experience architecting and delivering scalable web applications using React, Next.js, TypeScript, Node.js, and Python.

At Estospaces I built a Prop-tech MVP end-to-end, led a team of four interns, established Agile practices, and improved delivery speed by 30% while architecting AWS infrastructure to support 1,000+ daily active users with 99.9% uptime.

In prior roles I developed multi-tenant marketing platforms, a QR code certificate system that reduced verification time by 80%, and co-developed systems supporting 2,000+ concurrent users, while automating CI/CD to cut deployment errors by 90%.

I combine product research, user testing, and data-driven roadmaps with hands-on engineering to deliver robust, production-ready systems and mentor junior engineers to raise overall team quality.
