I'm Long Hải, an independent developer focused on crafting polished, cross-platform mobile applications backed by scalable server-side services.
About
End-to-end development from mobile UI to production APIs.
Backend & APIs
Behind every app is a dependable backend. I build RESTful APIs and services with Node.js and NestJS — authentication, subscriptions, analytics pipelines, and integrations that scale with your product.
Privacy & Trust
User trust matters. My applications follow transparent data practices, clear privacy policies, and secure handling of account and usage information — ready for app store review and real-world use.
