Specialization: Full-stack Developer

— Full-stack developer with a passion for building scalable, impactful software across industries. — My career began at IBM Research, where I worked on a web-scale text analytics platform, honing my skills in robust system design and testing. Transitioning to freelancing, I delivered tailored solutions for clients in healthcare, auction/project management, and startups—including projects for Fidelity Life’s Rapid Decision Software, Blitz Esports, and fintech/spreadsheet tools. — Since early 2024, I’ve pivoted to Web3 development, excited by blockchain’s potential to transform industries. My background in both enterprise and agile environments allows me to bridge technical depth with user-centric execution—whether refining legacy systems or prototyping decentralized apps.
