Om Jee Mishra

Senior Software Developer

Multi-agent RAG, real-time voice, and the infrastructure under it — with a heavy bias toward building in the open.

Gurugram, Haryana, India Open to senior backend & applied-AI engineering roles

I'm a Senior Software Developer with 3+ years shipping production systems at the intersection of full-stack engineering and applied AI. I architect multi-agent RAG platforms where a single agent runtime drives both streaming chat and realtime voice over the same tools, memory, and knowledge base — grounded in vector search, persistent conversational memory, and live CRM/EHR context, with server-authoritative workflows, prompt-injection defense, and per-turn LLM evals on top. I care about latency budgets, eval harnesses, and the boring reliability work that lets a team ship without rewriting on Monday — and I do a lot of that work in the open, contributing to RedPlanetHQ's Town and CORE.

Open source — built in the open

Open source is where I do my most deliberate engineering — small, well-tested, reviewable PRs against real production codebases. Two projects I care about most, with every merged PR one click away:

Senior Software Developer · HexaHealth

Architecting HealthGpt, the company's AI gateway — one agent runtime powering both a streaming text chatbot and a realtime voice assistant over shared tools, memory, RAG, and live patient context.

  • Architected HealthGpt, the AI gateway — one Mastra agent runtime powering both a streaming text chatbot (SSE) and a realtime voice assistant (WebSocket ↔ Gemini Live) over shared tools, memory, and RAG
  • Built namespaced Pinecone retrieval over treatments, hospitals, doctors, and uploaded medical PDFs, with an online ingestion pipeline and a query-rewriting symptom checker
  • Hydrated each conversation with live CRM/EHR context from MySQL via LLM summarization, and shipped a server-authoritative, restart-safe appointment-booking engine that never fabricates a lead
  • Hardened and instrumented both channels — prompt-injection defense, WebSocket rate guards, transcript-leak sanitization, sampled LLM-as-judge medical scorers, and end-to-end Langfuse tracing — with DB-driven, hot-swappable agent prompts, models, and tools

Software Developer · Wasserstoff RJ Innovations

Owned the backend for Lit Law — microservices, RAG pipelines, real-time collaboration and payments in legal-tech.

  • Built 40+ REST APIs over a gRPC microservices architecture (Node/Express, PostgreSQL, Redis, Drizzle) at 99.9% uptime and 2.3× throughput
  • Shipped RAG for legal contract generation with custom embeddings + Pinecone — 48% retrieval latency reduction, scaling to 1,500+ concurrent users
  • Delivered real-time collaboration (presence, concurrent editing) over SSE with a Next.js SSR front end
  • Integrated Razorpay/Cashfree with 100% reliability across 500+ monthly signings; migrated 8,000+ posts across CMSs with zero data loss

Writing

I write about the systems I ship — with a heavy focus on open source and the infrastructure decisions that decide whether it survives production.
