Every solid system
starts with a strong foundation
Since beginning my journey as a backend developer, I’ve had the chance to build enterprise platforms and government applications — always with a focus on scalability, performance, and clean architecture. Over the years, I’ve worked with Agile teams, tackled ERP systems, automated DevOps workflows, and brought CI/CD pipelines to life. Lately, I’ve been diving into AI and Machine Learning, blending traditional software craftsmanship with cutting-edge tech. I’m quietly confident, endlessly curious, and constantly refining my skills — one line of code at a time.
