About Me

Building apps that matter.

I'm Mark Muya, a full-stack and mobile developer passionate about creating software that genuinely helps people. Whether it's a mass intentions platform that unites Filipino Catholic parishes in prayer or an open event registration tool that makes gatherings effortless — I build with purpose.

My stack spans React Native for cross-platform mobile apps, Next.js for blazing-fast web experiences, and AI APIs like Claude and OpenAI to add intelligent features that delight users.

I'm currently open to new opportunities — full-time roles, contract work, or exciting collaborations. Let's build something great together.
