Full-stack developer in Colombia
I build web products end to end: from the data model and API to a PWA you can install on your phone. I work with specs, PRs and CI to ship small, verifiable changes.
I created the AllAtYou ecosystem: a family of products for fleet operations, workshops, bookings and communities, each deployed independently.
I work spec-first: every change starts from an issue and a spec with explicit scope, moves forward on a branch with conventional commits and merges only with green CI. That keeps the pace high without losing traceability, including when I work with AI assistants.
Products I built and maintain. Closed-source ones are shown as case studies.
Financial operations for a vehicle-rental fleet
Monorepo with an API and a web app to record payments, expenses and operating advances, attach receipts and produce arrears, monthly profit and ledger reports.
Multi-tenant SaaS for auto repair shops
Management and quick diagnosis for auto repair shops in Colombia. Each shop is an isolated tenant and the app is connected to the Renting Hub fleet.

Self-hosted app that measures mindset, execution and results through a daily check-in. Installable as a PWA, works offline, available in Spanish and English.

PWA with a TikTok-style vertical feed. Login is only asked when publishing, with Google or a WhatsApp code, and payments run through Stripe.
PWA for the Santa Elena market square (Cali)
Connects Cali shoppers with the market vendors. Deployed with SST and OpenNext on AWS Lambda and CloudFront.
Reservations and scheduling, with an aesthetics variant
Reusable booking system. A vertical variant serves an aesthetics clinic.
