Abhishek Sharma

AI Engineer based in Berlin. I build production LLM agent systems — voice and chat agents, RAG pipelines, and the retrieval and orchestration plumbing that makes them reliable in the wild.

Currently building applied LLM systems in production. Off-hours I write about system design and turn research ideas — diffusion, clustering, rare-event learning — into small, readable repos.

Selected work

  • ai-phone-assistant — Production-grade healthcare phone agent. Google ADK, FastAPI, Kubernetes.
  • Trip-Planner — Autonomous AI agent that plans end-to-end trips.
  • feynman-technique — A Claude/Codex skill that turns resolved engineering work into reusable learning notes.
  • system-design-playbook — Mental models, tradeoffs, and failure modes for system design.
  • variational-fuzzy-kmeans — Soft clustering via a variational free-energy objective.
  • entropy-afl-reranker — Entropy-regularized focal filtering and calibrated reranking for rare-event classification.
