Tung P.

Full-Stack Developer | Web Apps & Mobile Apps & SaaS

I build fast, modern web applications that ship on time. I'm a full-stack developer specializing in Next.js, React, Firebase, and Tailwind CSS, deployed on Vercel. Beyond client work, I build and run my own SaaS products, so I understand the full picture: clean code, conversion-focused UI, SEO, analytics, and payments integration. What I can do for you: • Build complete web apps and SaaS products from scratch (frontend + backend + database) • Landing pages that load fast and convert (SEO-optimized, mobile-first) • Integrate payments (Stripe, Polar), auth, email flows, and third-party APIs • Fix, improve, or extend existing Next.js/React codebases Recent work: • Built and launched PainBase, a research SaaS with AI analysis, payment processing, and automated email sequences • Built AImageResize, an AI image tool with credit-based pricing • Long-term development work for international clients I communicate clearly, give realistic timelines, and deliver working software, not excuses. Let's talk about your project.
