About Me

Computer Science graduate from PUCP

No. 1 university in Peru – Ranking QS
. I'm focused on software development and motivated to build efficient solutions with modern technologies like Java, React, SQL, and .NET. Self-taught and passionate about participating in projects that pose real technical challenges.

For my thesis, I built an interoperability module for OpenMRS integrating with Peru's National Electronic Health Records Registry (RENHICE) using HL7 FHIR R4 and Dyaku profiles. This deepened my understanding of healthcare standards and service-oriented architectures.

Outside of academics, I enjoy exploring game development, participating in game jams, and designing illustrations or logos as a hobby. These activities strengthen my creative thinking and practical approach.

What I enjoy most is developing systems, web applications, ERPs, and CRMs. I'm passionate about building robust and scalable solutions that solve real-world problems.
