Founder & CEO at Arclo Systems · San José, Costa Rica
I build software other people use daily. I lead the architecture and the team, and I still write the code.
Kodi — Prep app for university admission, national tests and COSEVI licenses. Design, development, infrastructure and release.
React Native NestJS PostgreSQL
Transportes Acaya — They ran on a spreadsheet nobody could edit at the same time. Now it is the system they invoice from: every trip has a status and a calculated fare, third-party settlements and purchase orders come out of the same place, and each user sees what their role allows. Over 1,500 trips managed.
Next.js NestJS PostgreSQL Prisma
T-Ledger — Real double-entry accounting for your personal, couple and family ledgers. Budgets, debts, goals and investments that balance, and every figure traces back to its source.

MiBrete — Our own product, in development. Details when it ships.
Novelteak · 2024–2025 — I was part of the team that built the offline-first app crews use to run field work with no signal, and the multi-tenant platform behind it. I handled the per-area modules, role-based access control and the technical documentation. Both run in Costa Rica and Nicaragua.
GSIT · 2022–2023 — I led Scrum projects for banking, retail, tourism and industry clients across Costa Rica, Nicaragua and Guatemala. I built the test plans, the automated suites and the QA standard the team used afterwards.
TypeScript end to end. Next.js and Astro on the web, React Native and Expo on mobile, NestJS and Prisma on the back, PostgreSQL underneath. DigitalOcean for infrastructure.
