// Software Developer
Full Stack · System Design · Nairobi, Kenya
I build fast, reliable software - from scalable backends to sharp interfaces. Focused on writing clean code that solves real problems and delivers value.
About
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.

A Hub For Custom ROMS and Recoveries. I built a platform to simplify the process of finding and installing custom ROMs for Android devices. Integrated with multiple ROM repositories and provided a user-friendly interface for browsing, downloading, and installing ROMs.

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.

AI-powered contract risk analyzer that turns complex legal documents into clear, actionable insights. Upload PDFs, DOCX files, or paste text to automatically extract clauses, identify high-risk provisions across areas like liability, indemnity, data privacy, and IP, and generate structured investigator-style memos with evidence-backed findings, risk scoring, and negotiation-ready recommendations.
