About
John Uel Mangaba
Full-stack developer based in the Philippines. I help clients and teams ship product interfaces, APIs, and databases. Sites and systems that are fast, easy to maintain, and ready to grow. Building and shipping since 2023.
Open to contract, freelance, and remote roles. If you need someone who can own the UI through the backend and into launch, let's talk.
