John Michael Buan

I am a full-stack software engineer focused on building cross-platform mobile apps and scalable web APIs using Flutter and Laravel. I combine mobile development expertise with backend and database design to deliver production-ready solutions.

I lead development for internal government systems and e-commerce platforms, implementing PostGIS-enabled geospatial queries and optimizing database structures for performance. I also design application architectures and coordinate development phases with stakeholders.

My tech toolkit includes Flutter, Kotlin, Laravel, ReactJS, PostgreSQL, MySQL, Docker, NGINX, and AWS services, and I actively participate in code reviews, query optimization, and deployment automation. I have hands-on experience integrating systems such as budget and accounting workflows.

I value clear planning, maintainable code, and collaborative handovers; I train client personnel, document solutions, and ensure deployments are secure and performant to support reliable, scalable products.
