About Rahul Kolekar
Hi, I’m Rahul Kolekar
AI Engineer – I build practical AI/ML tools, agentic workflows, and production-style RAG systems. Sharing code-first guides and open-source projects.
AI/ML breakthroughs, systems design strategies, software engineering deep-dives, and case studies delivered weekly.
About me
- I build practical AI/ML tools and learning resources
- Interested in: LLM systems, RAG, agentic workflows, LLM evaluation, MLOps, and applied ML
- I enjoy writing clear, code-first guides with real examples
- Open to collaborations, open-source contributions, and building useful AI products
