Hire me

I'm a senior full-stack engineer (React, Next.js, Node.js) with 12 years shipping products for companies in the US, Sweden and Argentina, most recently as Tech Lead at KitchenSync, leading a team of 4. For the last few years my focus has been putting LLMs and agents into products that handle real money and real documents.

What I'm looking for

• Roles: senior / staff full-stack, tech lead, or AI-integration engineer.
• Modality: remote, contract or full-time. I invoice in USD.
• Time zone: Medellín, Colombia, GMT-5: full overlap with US Eastern and Central business hours.
• Start: available now.

What I bring

• End-to-end ownership: architecture, code, CI/CD and infrastructure (AWS, GCP, Terraform).
• LLM features that hold up in production: structured outputs, validation, fallbacks, evals, cost control.
• Agents and tooling: Claude Agent SDK, MCP servers, multi-agent workflows.
• Leading small teams: code review, mentoring, turning fuzzy requirements into shipped features.
• Certified Scrum Master, Product Owner and Developer. English C1.

How I work

I start by writing down what success looks like and what could go wrong, ship the smallest version that proves it, and measure before I polish. I write decisions and trade-offs down, because the next person to touch the code is usually me in six months.

Proof

• Patas Arriba Travel: pet exports, from discovery notes to production in 16 days (case study)
• Building an LLM feature, end to end
• LLMs in production: the hard part is the contract around the model
• Designing an MCP server an LLM can use safely
• What I learned leading a team of four engineers
• Open source: auth-reference and ai-development-team
