About
Hi! I'm Aufstin Filiko — a full stack blockchain and AI specialist based in San Francisco, CA.
I've always been drawn to solving complex problems with elegant, efficient code. Over the years, I've built everything from scalable web apps to sophisticated DeFi platforms and AI-powered applications, using languages like Python, C++, JavaScript, and modern frameworks like React, Next.js, and FastAPI.
My expertise lies in blockchain development and AI integration, where I've architected and deployed multiple DeFi protocols, DEX platforms, and crypto trading systems. I've built CEX-like trading environments with advanced features like TL/SL, developed mobile crypto wallets for both iOS and Android, and created staking platforms with tournament mechanics.
I have hands-on experience developing on multiple blockchain networks including Ethereum, Solana, and Bitcoin Runes, with deep knowledge of smart contract development using Solidity and Web3.js. My projects span from MMORPG3 gaming platforms on IMX to cross-chain payment solutions and automated trading bots.
In the AI space, I've developed AI response aggregation platforms, implemented computer vision solutions using OpenCV and TensorFlow, and built intelligent automation systems. I've worked with machine learning frameworks, data processing libraries like Pandas and NumPy, and created AI-powered tools that enhance user experiences and streamline complex workflows.
More recently, I've been focused on building comprehensive blockchain infrastructure and AI-powered solutions, from chain explorers and treasury management systems to automated workflow solutions that bridge traditional web technologies with cutting-edge blockchain innovations and artificial intelligence.
I specialize in creating scalable, secure, and user-friendly applications that solve real-world problems. Whether it's building DeFi protocols, developing AI-powered tools, or architecting complex web applications, I bring a unique blend of technical expertise and creative problem-solving to every project.
Take a look at what I've been working on — and feel free to reach out if you'd like to build something awesome together!
