Multi-agent RAG, real-time voice, and the infrastructure under it — with a heavy bias toward building in the open.
I'm a Senior Software Developer with 3+ years shipping production systems at the intersection of full-stack engineering and applied AI. At HexaHealth I architect multi-agent RAG platforms over Mastra AI + Gemini, real-time bidirectional voice over WebSocket, and the observability and security layers around them. 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:
RedPlanetHQ/Town
Discord, but you walk around a pixel town — where the NPCs have skills
A pixel-world where AI NPCs walk around, chat, and act on real connected tools. My work made Town cheaper to self-host, gave NPCs real capabilities through CORE, and added the project's first test suite.
- Added Ollama as a third LLM provider (Ollama Cloud, OpenAI-compatible) so Town runs without a paid Anthropic/OpenAI key — with matching town-cli support and a fix so streamed Ollama chats correctly debit aura (#37, #45, #47)
- Wired CORE integrations into NPCs: owners can grant specific integrations and actions to characters, and signed-in visitors can lend their own CORE tools for a conversation (#71, #72)
- Bootstrapped testing — added Vitest and 61 unit tests over security-relevant modules (prompt sanitisation, town-code, events) (#34)
- Fixed onboarding by adding the missing .env.example files the setup guide referenced (#20)
- 7 pull requests, 4 merged — spanning provider support, agent capabilities and tests
RedPlanetHQ/C.O.R.E.
Your Personal AI OS
A shared memory graph and MCP layer for AI agents. I contributed read-only tools, self-hosting fixes, and a deterministic test suite over previously untested agent internals.
- Shipped 16 read-only MCP tools across two features — a full Postman integration (14 tools) and skills-as-tools (list_skills / get_skill) for coding agents
- Unblocked self-hosted deployments end-to-end: fixed four defects on the local-Ollama path with zero change to the hosted OpenAI / Anthropic / Google providers
- Fixed production bugs across API-key deletion, multi-step chat rendering and Ghost HTML publishing
- Added 62 fast, deterministic unit tests over previously untested agent helpers (action-plan parsing, tool-result truncation, history prep)
- 8 pull requests, all merged — roughly 4.1k lines contributed
Experience
Senior Software Developer · HexaHealth ↗
Architecting a multi-agent RAG platform with real-time bidirectional voice, persistent memory, and production-grade observability for healthcare workflows.
- Architected the Saksham multi-agent RAG platform on Mastra AI + Gemini 2.5 Flash with Pinecone (768-dim, 5+ namespaces), hitting sub-2s retrieval over 10K+ indexed documents
- Engineered real-time voice over WebSocket with a 4-state turn-management machine, cutting voice latency 40% while sustaining 50+ concurrent sessions
- Built persistent memory in PostgreSQL and 7 LLM-callable tools; wired end-to-end tracing via Langfuse + OpenTelemetry
- Hardened production with prompt-injection detection, one-time session tokens and IP rate limiting — 95% fewer unauthorized attempts
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

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