Hey! I'm Sarthak — creator, AI architect, and systems thinker rewiring life one rep at a time.
I build real-world AI agents, chatbots, RAG systems, fine-tuned LLMs for fast-moving teams that don't have time to waste.
Featured Work
An agentic chatbot that translates investor queries into FinQL and returns data-rich insights.
Kind Words

I had the pleasure of working with Sarthak and his team on an MVP to validate a business idea. I’m extremely happy with the experience. Sarthak knows how to ship fast and is proactive in identifying and clearly explaining the trade-offs behind technical decisions. Overall, working with him felt almost like working with a cofounder.

His work ethic, attention to detail, and bias for action makes him stand out from the rest as he brings in expertise in technical architecting and project management. Would highly recommend working with him on ML/AI, and end to end product development.

Sarthak is a thorough purist and never hacks around to get things done. He believes in going deep and doing things the right way. And, many of his insights during code reviews has made many engineers better.
Helping Builders Build
I work with ambitious people who feel the itch to build.
Founders stuck in cushy jobs. Engineering leads fumbling through AI adoption. Business owners falling behind the curve.
They often show up with duct-taped agents, no-code demos, or low-accuracy pipelines that don't quite hold up. What they really need isn't more AI. It's clarity. It's momentum. It's systems that actually work.
That's where I come in.
Over the last ten years, I've worked with more than 15 startups, fine-tuned 20+ models, and built prototypes that went from idea to real-world validation in just a few weeks. One product scaled to 10 million users. A few raised their first round. Others finally got paying customers after months of spinning their wheels.
I bring deep AI experience, but I'm also an engineer at heart. Sometimes that means building an agentic system. Sometimes a simple ML model. Sometimes no AI at all. What matters is getting it working - fast, reliably, and in the hands of real users.
When I'm not building for others, I'm building for myself. I journal my life experiments on Rewiring Life, and I'm currently working on two projects I care deeply about — TinyShift and TryLess.
If you're sitting on an idea, or trying to move from a prototype to something real, I'd love to help. Let's figure it out together.
Build in 21 days. Validate faster. Impress investors.
Startups I've worked with have raised funding, closed enterprise deals, and shipped AI products that actually work. I move fast, so you can too.
