Hey, I'm Abhinash Dutta 👋

AI Engineer | Backend Engineer | Systems Programmer

I build applied AI products, backend systems, and low-level Linux software. Most of my work sits around retrieval and agent workflows, distributed services, and systems close to the kernel and networking stack.

Featured Projects

Applied AI

• Chiron • Python, FastAPI, LangGraph, React, SQLAlchemy, Gemini
  Evidence-grounded agentic medical research assistant for clinicians with LangGraph retrieval planning across medical sources, citation-backed synthesis, live run traces, and verification gates that clarify or abstain when support is weak.

• Anchor • Python, FastAPI, LangGraph, PostgreSQL, pgvector, Langfuse
  Citation-grounded RAG system over Indian financial regulations using hybrid retrieval, reranking, and continuous evaluation.

Backend / Infra

• Photon • Go, Postgres, Redis, Kubernetes
  Async image-processing backend with worker queues, object storage, and observability.

• Collaborate • TypeScript, React, Express, Socket.IO Anonymous real-time whiteboard with server-owned room state, typed shared contracts, reconnect-safe sessions, and bounded persistence.

• Guardian • Python, Prometheus, Ansible
  Monitoring and auto-remediation pipeline that bridges Prometheus alerts to automated Ansible playbooks.

Systems / C++

• K-Watch • C++, eBPF/XDP
  High-performance network observability engine with SYN-flood detection and auto-mitigation built on kernel-level instrumentation with sub-5% CPU overhead.

• Vortex • C++, Linux
  Zero-dependency container runtime built from scratch using Linux namespaces, cgroups, and filesystem isolation.

• PacketForge • C++20
  Userspace L2/L3 network stack that hand-crafts ARP, ICMP, and raw Ethernet frames over AF_PACKET.
