Micro Crédito
Problem
Financial institutions had no scalable way to manage the complete credit lifecycle—from application to monitoring. Manual workflows were slow and error-prone.
Solution
Built a comprehensive fintech platform enabling credit analysis, simulation, approval, and real-time monitoring.
My role
Led full-stack architecture using NestJS + Prisma (backend) and Next.js (frontend), designed microservices patterns for scalability, and implemented authentication & real-time notifications.
Results
Deployed to production handling 500+ daily transactions, reduced approval time from 5 days to 1 day, 99.2% uptime SLA.
Tech stack
NestJS, Next.js, PostgreSQL, Docker, Redis.
