Full-stack developer — Medellín, Colombia

I ship production software with real users behind it. Not tutorials, not clones.

I founded C3LECT, a premium watch and fragrance retailer, and I wrote the entire platform it runs on: the customer-facing catalog, the REST API, the payment integration, the inventory system and the admin dashboard. Real orders, real money, real customers on the other end.

By day I'm an electromechanical technologist at Metro de Medellín — critical infrastructure where a failure is not an inconvenience, it's a headline. That's where I learned to build things that don't break. I'm completing a Software Development degree at SENA.

Modular NestJS + Prisma + PostgreSQL API running the C3LECT store.

• Auth: email/password and passwordless OTP, JWT access + rotating refresh tokens, password reset, Argon2 hashing, per-route throttling, enumeration-safe responses
• Payments: MercadoPago integration with signature-verified webhooks and a pending-payment flow — the order is only created once payment is approved, so abandoned checkouts never leave orphan records
• Orders: guest and authenticated checkout, status machine with full history, automated customer email notifications
• Business layer: master inventory, cost/price calculation, purchases, expenses, historical sales and a financial metrics dashboard
• Hardened: Helmet, strict CORS, global validation pipe, RBAC guards, audit log on every mutation, graceful shutdown hooks
• 📘 Interactive API docs: Swagger / OpenAPI (hosted on Render's free tier — first request may take ~50s to wake the instance)
