Software Developer with ~4 years of experience spanning frontend, full-stack development, and cybersecurity. Started my career at DCKAP as a Frontend Developer and Penetration Tester, where I built scalable web interfaces using React.js and Next.js for international clients, and proactively identified critical security vulnerabilities such as XSS and HTML injection. Later, at Jardyan Inc., I worked as the sole Full-Stack Developer, building a complete journal publishing platform from scratch using React.js, Node.js, and MySQL. I handled everything from developing admin back-office portals and WYSIWYG editors to configuring VPS servers with Nginx load balancing and custom firewalls. After exploring quantitative crypto trading, building algorithmic strategies with the Binance API, and diving into DeFi protocols, I joined Potafo as a Full-Stack Developer in late 2025. Currently, I work with the Next.js and Python FastAPI stack, building real-time geospatial analytics heatmaps using open-source mapping solutions, and leading the transition of legacy Django monoliths into modern, AI-augmented microservices. My journey into tech is driven by an enduring curiosity to build, break, fix, and innovate.
