About Kumar Deepansh

I am a forward deployed engineer. I embed with a business, learn how the work really gets done, and ship the software or AI system that fixes it, end to end.

For the last year I have been the sole engineer on an AI workflow and messaging platform with 300,000+ sub-accounts and 100M+ messages. I rebuilt it from Bubble.io onto Next.js, Node/TypeScript and Postgres, which cut infrastructure spend 60%. I built the queue runtime behind its AI workflows (40+ queues, load verified at 1,000 req/s) and added Langfuse tracing on the LLM calls, so a failed run can be explained, not guessed at.

Before that, four years at an AI and software agency, shipping client work from scope to deploy: dashboards, client portals, multi-tenant SaaS, and an AI marketing ERP with 1K+ daily users. I became Team Lead over 14 engineers there.

On my own time I build agent infrastructure. Lumbox gives AI agents a mailbox, a browser session and a credential vault behind a 77-tool MCP server, and AgentCursor lets an agent drive any Mac app by reading windows as text instead of screenshots.
