Job Success
Chennai, India - 6:48 am local time
I work best with teams that have a real build behind a real reason: an AI product to take to market, a platform to move from prototype to revenue, or a costly workflow to automate away.
How I approach it:
- Start with the outcome — what does this need to earn, save, or unlock? Then design the smallest thing that gets there and grows from it.
- AI where it pays for itself — autonomous agents with tool use and retrieval (RAG), LLM chat and voice, and integrations. I've published my own MCP server (memgit) on npm.
- Automation that removes real cost — pipelines that cut manual operations and save teams 100+ hours a month.
- Full-stack product engineering — architecture, APIs, and a deployed, documented product you can build a business on.
- Security-aware when it matters — I can get a build SOC 2- and audit-ready, with controls in the stack.
A production AI SaaS MVP (my highest-rated delivery here), 10+ production voicebots automating ~80% of routine inquiries, and an event-driven platform handling 1M+ jobs a day at 70% lower latency.
I can run a build solo end to end, or embed with your team and lead the technical side — whichever ships it faster. Fixed-scope milestones, clear communication, and I own the result.
Have a serious AI or platform build in mind? Tell me the business goal behind it and I'll come back with an approach, scope, and timeline.
