Experience
INSA Cyber Talent Summer Camp July
Participant
Selected for Ethiopia's premier cybersecurity training program Completed hands-on labs in Linux administration, networking, OWASP Top 10, and API security Built an AI-powered penetration testing tool and presented at the camp's startup competition Worked on real-world CTF challenges and vulnerability assessments
Independent Contractor / Open Source Developer
Full-Stack & Web3 Developer
AI-Powered Smart Contract Auditor (Chain Sentinel): Built a tool that securely proxies Solidity code to Google Gemini AI to identify high-risk vulnerabilities and generate risk assessments. (Tech: Next. js, Type Script, AI Integration) Web3 Exploit Playground: Authored Proof-of-Concept exploits using Foundry, successfully recreating the DAO Reentrancy Attack to drain a vulnerable vault of 10 ETH in a single transaction. (Tech: Solidity, Foundry) Enterprise SaaS Dashboard: Architected a high-fidelity dark-mode platform with database-driven Role-Based Access Control (RBAC) and real-time data visualization. (Tech: Next. js, Type Script, Tailwind, Supabase)
