Charlie Casiano Mangyaw
Passionate Software Engineer
Computer Science student architecting performant web platforms, cross-platform mobile apps, automated pipelines, and civic intelligence engines. Grounded in clean architecture, practical systems engineering, and open source collaboration.
About Me
Architecting purpose-driven software with clean design patterns, practical systems engineering, and open collaboration.
Engineering Approach
I am driven by turning intricate problems into clear, dependable software. Rather than treating code as just syntax, I approach development from a systems perspective—prioritizing architectural clarity, maintainability, and real-world utility in every layer I touch.
My experience spans full-stack web platforms, cross-platform mobile apps, and automated data pipelines. Whether architecting civic intelligence engines like ProjectTrack to uncover public infrastructure insights through graph databases, or applying Domain-Driven Design to space exploration apps, I enjoy solving concrete challenges that deliver measurable value.
Outside of solo engineering, I thrive in collaborative hackathons and open-source ecosystems. I value clean abstractions, well-documented APIs, and continuous iteration with forward-thinking engineering teams.
