Full-Stack Software Engineer building banking platforms at Banco Cuscatlán and concurrent microservices for TIGO Honduras.

Honduras

Message

At Banco Cuscatlán, I led a team of four developers for the main web banking platform and co-led the core platform Matrix. I also mentored more than eight developers and team members in SOLID, GitFlow, and testing.

I developed complex credit card and payment modules in a regulated banking environment. Earlier at Banco Cuscatlán, I migrated a regional platform from Angular 16 to Angular 18 and introduced automated quality gates.

At TIGO Honduras, via Baas Technologies, I designed and built a NestJS microservices ecosystem using Apache Kafka for asynchronous messaging and nationwide mass provisioning. I also designed persistence schemas with CassandraDB and PostgreSQL.

In my current independent projects, I develop full-stack applications and prototypes with TypeScript, React, Node.js, and NestJS, covering APIs, testing, and AWS deployments. I'm also designing a proprietary SaaS platform and exploring cloud architectures and distributed systems with Go.
