02Behind the work
A little about me.
I’m Johan, a software developer based in Lima. I like understanding how things work, and making them work better.
A Computer Science graduate from PUCP, I build web applications, ERPs and CRMs with a focus on practical, reliable solutions. My work spans full-stack development, deployment and the details that make a product useful.
For my thesis, I built an OpenMRS module that connects with Perú’s National Electronic Health Records Registry using HL7 FHIR. It brought together two things I enjoy: complex systems and work with a real-world impact.
I work across frontend, backend and deployment, with a focus on reliable systems, integrations and maintainable code.
