👋 Hey, I'm Dre

React Native iOS Engineer • Full-Stack Builder • AI Product Developer
Based in Bangkok • 11-Year U.S Air Force Veteran • Freelance Engineer on Upwork


I build mobile and web apps — fast, clean, and ready to ship.

I've spent years turning ideas into real products for founders, startups, and agencies. I care about clear communication, simple architecture, and actually getting things done. No fluff, no drama — just working software.


🚀 What I've Built

🧠 AI Assistant Platform

A fully working AI assistant with smart features:

  • Handles multiple tasks like billing, support, and policy questions
  • Real-time chat with smooth streaming replies
  • Clean dark-mode design with motion effects
  • Retrieves context from documents using RAG
  • Works with OpenAI and AWS Bedrock

Built with: Next.js, FastAPI, LangChain, ChromaDB


✅ Todox — Task Manager

A clean, modern task manager with everything you need:

  • Priorities, labels, due dates, and a simple UI
  • Next.js frontend + FastAPI backend
  • Fully documented API and end-to-end tests

🔒 Referral Tracking System (NDA)

A production-grade system for tracking referrals — can't share the name, but I can share what went into it:

  • Built with Next.js and PostgreSQL
  • Deployed on Vercel with error monitoring via Sentry
  • Full documentation, architecture, and clean Git workflow

🎯 How I Help Clients

I work with people who need:

  • React Native iOS apps — built from scratch or rescued from messy code
  • Dashboards and SaaS frontends — clean, responsive, production-ready
  • Backends that make sense — FastAPI or Node, simple and maintainable
  • AI features — chat, agents, document search using OpenAI or Bedrock
  • Fast MVPs — tight feedback loops, quick iterations
  • Deployment help — Vercel, Railway, AWS, Docker — whatever fits

If you want someone who ships, communicates, and keeps things moving — I'm your guy.

📌 How I Work

Step What Happens
1️⃣ Understand the goal — I ask questions until I get it right
2️⃣ Break it down — into clear, simple deliverables
3️⃣ Ship early — you see working builds fast
4️⃣ Stay in touch — regular updates, no surprises
5️⃣ Finish clean — stable code, docs, smooth handoff

I'm a good fit if you value speed, clear communication, and real progress over endless meetings.
