About

Eleven years across FinTech, InsurTech, and the architecture of agent systems.

Sagar Thakkar

I'm Sagar. I architect AI agent systems and production-grade FinTech / InsurTech platforms - the kind that have to survive 11:30 PM firefights, regulator audits, and quarterly cloud-cost reviews. I started in mechanical engineering, drifted into code because the hardest problems were there, and have spent the last 11 years learning the difference between systems that look elegant on a slide and systems that actually hold up at p99. I write about both.

Most production AI agent systems fail because people design them like chatbots. Agents need clear routing - orchestrator, leads, specialists - not free-form conversation. The same pattern as any well-run org.

On AI agents

I used to think LLMs would replace architecture work. Two years of building production AI systems convinced me of the opposite - LLMs amplify the cost of bad architecture. The harder the model, the more brutal the design debt becomes.
