Hire · Full Stack Developer · Latin America
I'm Nixon Marrasquin, a senior full stack developer in Ecuador. Hire one engineer to own the whole product, React and Next.js on the front, Node and NestJS with PostgreSQL on the back, and the deploy in between. GMT-5, USD, no agency markup.
The slowest part of most projects is the seam between frontend and backend teams. Remove it. I take a feature from data model to shipped UI, so decisions are fast and nothing gets lost in translation between contractors.

The point of nearshore is that you actually work together. LATAM shares your business day; offshore doesn't. You keep senior quality and lower cost without living on async.

Not prototypes, production systems serving thousands of users daily, where I built both the API and the interface on top of it.

I slot into your team as a contractor and adapt to your stack and process, so onboarding is measured in days, not weeks.
What founders and hiring managers ask about a full stack hire.
I own a feature from the database schema and API all the way to a polished, fast UI, plus the deploy. Frontend: React, Next.js, TypeScript, Tailwind. Backend: NestJS, Node, GraphQL/REST, PostgreSQL. Infra: Vercel, Docker, CI. You get one person accountable for the whole path, not a frontend and a backend contractor pointing at each other.
LATAM gives US and Canadian teams real-time overlap instead of a 10-12 hour offshore gap, senior engineers at a fraction of US cost, and strong English. I'm in Ecuador, which is on permanent GMT-5 (US Eastern) and uses the US dollar, so hours line up and billing is in USD.
For MVPs, internal tools, dashboards and most SMB and startup products, one senior full stack developer ships faster than a fragmented team because there's no hand-off overhead. When a project grows, I can help you scope and onboard more people into a codebase that was built to be extended.
Production apps used by thousands of people: Nelson GO, Semillapp, Siglo 21 and DeWallet, plus their dashboards and APIs. 3+ years and 15+ delivered projects, front to back.
Native Spanish, B2 English. I run standups, code reviews, PRs and docs in English and handle async communication cleanly across Slack, Linear/Jira and Git.
All three. Full-time remote roles, ongoing contracts, and scoped end-to-end builds. Standard contractor agreement with full IP assignment, and I can usually start within a week or two.
