SYS_GREETING: Hi, I'm

Bernardo Carvajal Rivera

[Full Stack Engineer (Product Delivery)]

I turn complex fintech requirements into production-ready features. I build critical workflows with Angular, .NET, and Azure, from business discovery to deployment and operations.

About me

MY WORK DOES NOT END WHEN THE CODE COMPILES. I follow features from problem discovery to deployment and operations: UI, APIs, processes, validations, monitoring, and documentation.

  • Business understanding: My background in Organizational Psychology helps me translate business needs into technology, facilitate decisions, and grasp real impact.
  • End-to-end delivery: I ship complete features, not isolated components.
  • Built for operations: Solutions designed for auditability and maintenance (retries, idempotency, traceability).

I currently develop fintech products using Angular, .NET, and Azure.
