Where dual expertise adds value.
Engage when the problem sits at the intersection of law, software architecture, and operational complexity — not when you need a generic developer or a traditional attorney alone.
- Building legal-tech platforms, AI agents, RAG pipelines, or document automation systems.
- Architecting enterprise software with compliance, data governance, and regulatory constraints.
- Transport, logistics, and commercial disputes requiring both legal and technical depth.
- Crypto, blockchain, and high-integrity systems where architecture and accountability matter.
Two professions,
one vision.
I'm not just a developer who happens to know law — nor a lawyer who dabbles in code.
I'm Önder Yıldırım — a licensed attorney registered with the Istanbul Bar Association, practicing at Yıldırım & Yurdaöl Law Office. My legal practice spans commercial law, intellectual property, international transport & logistics, labor law, enforcement & bankruptcy, family law and corporate legal advisory for domestic and international clients.
Parallel to my legal career, I graduated with honors from the Software Department at Istanbul University. Over more than a decade, I progressed from Software Engineer to Architect Software Engineer, designing cryptocurrency systems, blockchain infrastructure, real-time trading platforms and secure integrations.
Today I combine both worlds: building Bluetree (formerly LawToolsAI), a multi-tenant legal AI platform with RAG pipelines, LangGraph agents and MCP protocol integration. I speak English and French fluently, and bring a rare dual perspective that most legal-tech teams can only dream of assembling.
