I'm John Garry Tan, a software developer based in the Philippines. I design and build websites, web apps, mobile apps, MVPs, and custom business systems — from early planning and UX to development and launch.
from a marketing site to a full web application, built to be responsive and maintainable.
iOS and Android apps for customers, teams, and mobile-first workflows.
chat, automation, and generative AI built into your product.
turn an existing design into a responsive, reusable frontend with the states and interactions worked through properly.
modernize an existing site or app, migrate what needs moving, and keep the useful parts.
join your team for focused implementation, backlog help, or a technical second opinion.
