Full-Stack Developer at Physeter who led Cuencana’s backend and built its loan disbursement and collection workflows.

At Physeter, I led projects from client requirements through production, including Cuencana, where I developed the complete backend for a savings cooperative platform. Built with NestJS and hexagonal architecture, it handles loan disbursements and collections with automatic payroll deductions.

At Jelou AI, I built conversational agents and WhatsApp chatbots on Brain Studio. For Toni, I implemented an anti-race algorithm to prevent duplicate prizes and built a control panel to help find campaign errors in time.
