About

You have product-market fit (or you're close), but you're stuck in the hiring loop — interviewing, onboarding, managing. Meanwhile, features aren't shipping. I skip that entire cycle. You get a senior engineer who's productive from week one, owns outcomes, and actually cares whether the thing works in production.

7+ years building production systems. TypeScript, React, Next.js on the frontend. Python (FastAPI) and Node.js on the backend. PostgreSQL, Elasticsearch, and vector databases for data. AWS and GCP for infrastructure. LLM orchestration, RAG pipelines, and agent workflows in production. The full stack, from UI to AI.

Based in Ecuador, working primarily with US and international clients. I overlap comfortably with US time zones and I've been remote-first for my entire career. I work best on long-term engagements, not one-off tasks — you're getting someone who owns the product end-to-end.

How I Help

01You need to ship but can't wait to hire

I embed into your team on a retainer — join your standups, own features end-to-end, ship on your cadence. You get the output of a senior hire without the recruiting, equity, or three-month ramp-up.

02You have an idea but no engineering team

I take it from concept to deployed product — architecture, backend, frontend, infrastructure. You get in front of users and investors with a real product, not a prototype.

03You're losing enterprise deals over missing features

SSO, audit logs, complex integrations, compliance requirements — the hard stuff that closes six-figure contracts. I've built these at scale and know what enterprise buyers actually need before they ask.

04Your product needs AI that works in production

If your product needs LLM orchestration, RAG pipelines, or agent workflows, I build those too — with structured outputs, cost control, and fault recovery. Not a standalone AI project, but AI that ships inside a real product.
