I’m a full stack developer with over 10 years of experience building all kinds of digital products—from websites and mobile apps to blockchain platforms, embedded systems, and AI-powered solutions. I’ve worn a lot of hats over the years, but the common thread has always been solving real problems with smart, reliable tech. Whether you’re looking to launch something new or need help improving what you’ve already built, I’m here to jump in and make it work. -Web & Mobile Apps: Clean, responsive designs and solid backend logic. I work with tools like React, Vue, Node.js, Django, Flutter, and more to build apps people actually enjoy using. -Embedded Systems & IoT: I build smart, connected hardware using platforms like Arduino, ESP32, and Raspberry Pi. From prototyping to production-ready firmware, I work with C/C++, MicroPython, and platform-specific SDKs to control sensors, motors, displays, and more. I also integrate these systems with web and cloud services—often adding AI for tasks like real-time data analysis, voice interaction, or image recognition at the edge. -AI & Machine Learning: I integrate tools like GPT-4, Whisper (speech-to-text), and DALL·E into web and mobile platforms—automating workflows, building chatbots, content generators, or even custom AI copilots for your users or team. I also work with Python-based ML frameworks like TensorFlow and PyTorch for custom models and training. -Blockchain & Smart Contracts: I’ve developed and audited smart contracts (mainly Solidity) and built dApps that connect seamlessly with Ethereum, Solana, and BNB networks. Let’s bring your vision to life with clean architecture, scalable code, and tech that lasts. I’m ready to contribute as your long-term tech partner or on-demand expert. ít hơn
