What I'm looking for

Looking for a challenging role that leverages my technical expertise and leadership skills to drive innovation and growth.

I'm a seasoned software engineer and technical lead with nearly a decade of experience in full-stack engineering, primarily in the JavaScript ecosystem. I'm product-centric, passionate about leading teams, and eager to take on technological initiatives. Presently focused on building AI applications.

Throughout my career, I've led teams of engineers in developing innovative solutions, including a parameterized RAG platform and a generative AI engine. I've also co-founded and led Quinvio, an interactive video platform pivoting to AI-generated videos, reaching 15K users and SMEs within three months.

I'm skilled in a range of technologies, including JavaScript, NodeJS, React, NextJS, Vercel, QDrant, Postgres, and more. I'm a strong leader, able to architect applications, hire talent, and set company-wide code standards.
