I work on integrations, AI workflows, realtime systems, payments, and internal tooling - the parts of a product that are hard to fake and expensive to get wrong. My background spans founder-led products, in-house engineering, and solo client builds.
At Blitzit, where I work on integrations, AI tooling, and backend systems that support daily product use.
Before that, I co-founded MaddyCustom and built the platform behind a business that grew to 100K+ monthly users and ₹60L annual revenue.
I also run Spyll, a consumer app that reached 1,200+ Android downloads in its first month without paid acquisition.
That mix matters. I have shipped as a founder, as an in-house engineer, and as a solo builder - which makes me comfortable owning both product tradeoffs and technical execution.
Built a plugin-based integration SDK that reduced new integrations from 10+ files to a single 300–500 line plugin. Built an MCP server with 13 AI-callable tools using OAuth 2.1 (PKCE) and JSON-RPC 2.0 over Streamable HTTP. Also worked on bidirectional sync with Asana, ClickUp, Notion, and Google Calendar across 21 timezones.

More context, if useful
The best fit is work that sits between product judgment and technical complexity.
If that sounds close, email me with the problem, the current stack, and where things are blocked.
