Available for work

I'm a software developer who builds things that work - and work well. I care about performance, clean architecture, and shipping products that people actually use.

When I'm not at the keyboard you'll find me gaming to ease my mind and having a fun time with my buddies. I bring the same focus and discipline to my code—and I put it to good use running circles around my mates on FIFA EA Sports FC .

Gaming is truly my second hobby next to coding. I also enjoying taking part in hackathons and I have a few projects from those in my GitHub. I have a passion for learning new technologies and applying them to solve real-world problems.

NanoPay

Built a per-request AI API where every query costs $0.001 USDC, settled onchain on Arc blockchain. Deployed a Solidity smart contract that accepts USDC micropayments, built a Node.js API server that verifies payments before returning Gemini AI responses, and demonstrated 57+ live onchain transactions. The project proves sub-cent API monetization is only economically viable on Arc, where gas costs are 100,000x cheaper than Ethereum.
