01. About me

Senior Full-Stack Engineer with 7+ years of experience turning ideas into production software. As a lead Full-Stack developer at Lokos AI, I have built AI-powered platforms end to end: Next.js and React front-ends, Python/FastAPI back-ends, AI voice agents, React Native mobile apps, payment integrations and Terraform-managed infrastructure on GCP and AWS. At Global Hitss I worked on Claro TV+, one of the largest streaming apps in Latin America: I led its Next.js App Router migration, owned login, checkout and payments, and supported on-demand video workflows with Bitmovin.

02. How I work

I care about the whole product, not just my layer: clear UX, type-safe APIs, automated tests, secure defaults and zero-downtime deploys. I work daily with AI-assisted development tools and enjoy integrating LLMs, voice and RAG into real products.

03. Interests and Hobbies

I am a devoted follower of technology; my hobby is more than just a pastime—it's a journey of discovery and innovation. Coding, tinkering with gadgets, or staying abreast of the latest tech trends, my passion for this field drives my curiosity and creativity in this ever-evolving landscape.
