Thang T.

I'm a Full-Stack Developer and AI Product Engineer who helps startups turn ideas into production-ready products. I don't see myself as someone who simply implements tickets. I work closely with founders to review product decisions, challenge assumptions when needed, improve technical architecture, and build solutions that are practical to ship and maintain. Over the past 5+ years I've worked with startups across the US, UK, Australia, Singapore and Europe, building AI products, SaaS platforms, web applications and mobile apps from MVP to production. My core expertise includes: • AI applications using OpenAI, Claude and Gemini • AI agents, RAG systems and workflow automation • SaaS platforms with Next.js, React, Node.js and Supabase • React Native apps for iOS and Android • Multi-tenant architectures, authentication and subscription systems • Business automation and API integrations I have extensive experience with modern AI development beyond simple chatbot integrations. This includes document understanding, OCR pipelines, knowledge retrieval, AI-assisted workflows, structured outputs, agent orchestration and production AI systems that solve real business problems. One area I particularly enjoy is reviewing existing products and finding better approaches. Sometimes that means simplifying an architecture, improving database design, strengthening security policies like Supabase RLS, reducing AI costs, or identifying product decisions that could become problems later. I believe writing code is only part of delivering a successful product. Some recent projects include: • AI lead qualification platform that analyzes websites, uploaded documents and company information with LLMs • Desktop AI translation application with OCR and contextual translation • Enterprise multi-tenant SaaS platform built with Next.js and Supabase • React Native social platform with maps, subscriptions and real-time features • AI-powered customer support and business automation systems I work comfortably as an independent engineer, communicate clearly, and enjoy collaborating directly with founders and small teams where product thinking matters as much as implementation. If you're looking for someone who can contribute beyond writing code and help build the right product, I'd be happy to discuss your project.
