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.

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.
This was part of a hackathon submission for the Arc Blockchain Hackathon which you can view the details

An autonomous incident-response system that monitors cloud infrastructure in real time, diagnoses issues with a three-agent AI pipeline (Monitor, Diagnosis, Remediation), and executes safe SSH-based fixes on remote servers. Streams live metrics over WebSockets, searches past incidents with a ChromaDB vector store, and auto-generates PDF post-mortems. Handles CPU surges, memory pressure, disk I/O, DDoS, and DB bottlenecks with a whitelisted command set, no arbitrary shell input.
Built for the AMD Developer Hackathon 2025 under Track 1: AI Agents & Agentic Workflows. You can demo this system here.
