What I'm looking for

I am seeking a remote role where I can provide technical leadership and hands-on engineering in an async-first team, focusing on scalable backend architecture, CI/CD automation, and mentoring while working on impactful products.

I am a Senior Full-Stack Developer and Team Lead with 7+ years building scalable production systems for companies across Spain, Canada, Belgium, and the US, delivering backend-first architectures and full-stack features using Node.js, NestJS, TypeScript, React, PostgreSQL, and MongoDB. I specialize in architecting backend systems from the ground up, optimizing data models and search with Elasticsearch, and owning end-to-end API delivery while mentoring teams and driving CI/CD and reliability improvements.

I have led cross-functional remote teams in async-first environments, shipped high-impact products including a regulated property valuation tool and an enterprise logistics tracking system, and reduced release time and API response latency through automation and migrations. I am seeking a remote role where I can contribute hands-on engineering and technical leadership to a product that matters.
