   Senior Software Engineer

   • Fintech & transactional core.

     Developed Golang microservices for the transactional core of a platform for employee fund management in Colombia, PCI DSS compliant, integrating the ISO 8583 protocol, an in-memory rules engine, and an event-driven architecture with Kafka, the Transactional Outbox pattern, and DLQ, with internal service-to-service communication over gRPC, achieving p99 latency under 500 ms under heavy load.

   • Multi-tenant & mobile platforms.

     Built a multi-tenant solution with a web platform (Next.js) and two mobile apps (React Native/Expo), featuring Socket.IO, Device Binding, OTP verification, and hybrid persistence (PostgreSQL/MongoDB).

   • Custom enterprise solutions.

     Developed platforms with NestJS, Prisma ORM, and PostgreSQL, featuring centralized SSO/RBAC authentication, multi-language (i18n) support, and a thermal calculation engine for automated equipment recommendations.

   • Modernization, security & observability.

     Migrated legacy services to Hexagonal Architecture and optimized MongoDB queries, reducing latency by 65%. Implemented structured logging, distributed tracing, rate limiting, and NoSQL injection protections.

   • Technical documentation & architecture.

     Produced technical documentation across several projects: C4 architecture, quality attributes, domain model, system flows and views, and functional backlog, working hand in hand with the client and the product team to gather requirements.
