Yetesfa A.

I build AI-powered platforms and full-stack products that work in the real world — not just in demos. Right now, I'm the sole engineer behind an AI-powered advertising platform that integrates Google Ads, Meta Ads, OpenAI, Stripe, and Firebase — from the React frontend to the Cloud Functions backend to the shared type system in between. I designed the architecture, built the API layer, wrote the AI analysis pipeline, and debug across every boundary. I also build AI agents, custom skills, and multi-agent systems using Claude (Anthropic), OpenAI, and prompt engineering. I design agent architectures with specialized roles, tool use, autonomous task execution, and structured output pipelines. If you need an AI agent that actually does useful work — not just chats — I can build it. My stack: TypeScript, Next.js, React, Firebase (Cloud Functions, Firestore, Auth), Google Ads API, Meta Marketing API, OpenAI API, Claude API, AI agent development, prompt engineering, Zustand, Flutter/Dart. I have a Computer Science degree from Mekelle University and 7+ years of professional experience. I've spent the last 4+ years working remotely for a German tech company, shipping production code across time zones. I'll tell you honestly if I'm the right fit. If I'm not, I'll tell you that too. I don't take projects I can't deliver on. And when I commit, I build it like it's my own
