Yerinmene Abraham S.

I build production AI and backend systems that need to be reliable, secure, and ready for real users. My work includes AI agents, RAG pipelines, LLM integrations, TypeScript/Node.js APIs, PostgreSQL, AWS, and distributed backend systems. I currently lead backend engineering on a production core-banking platform that handled 65,000+ requests in 30 days with only 2 server errors. I also built Lira Intelligence, a multi-tenant AI support platform across chat, email, voice, and WhatsApp, and Trackline, an open-source reliability layer for AI agents. I can help with: • AI agents, RAG, memory, tool calling and LLM integrations • TypeScript / Node.js backend systems and APIs • PostgreSQL, Redis, Kafka and AWS • AI evaluation, debugging and reliability • Existing systems that need fixing, scaling or improving I work independently, communicate clearly, and focus on shipping things that actually work in production.
