AI & Platform Product Leader — Agentic AI, ML, APIs & Payments
I've built AI products since 2017, from ML recommendations at 8,000 merchants to agentic RAG systems that doubled leads closed, on top of payments and API platforms that moved $1B+ GMV. The lesson each time: AI and payments only matter once they're trusted in production.

What colleagues say
From people who worked with me on payments, product and platform work.
I have worked with Janahan quite extensively and on one notable project, he was instrumental in ensuring that the transition from one payments provider to another, was timely and smooth. That was an extremely complex task involving a new product, multiple stakeholders, and sensitive and aggressive deadlines. In the first 2 months of the launch itself, the product reached ~$10M in volumes!
Kanika Mittal
VP Fintech & Partner, Travel Payments
What stood out consistently was his sharp product intuition and his ability to craft solutions that were not just functional, but genuinely aligned to market needs. He has a rare ability to listen deeply, to customers, and to the market and translate that into extraordinary product outcomes. He was a true partner in every sense, collaborative, grounded in data, and always thinking a few steps ahead.
Sameer Kaushik
VP Sales, TabSquare AI
What makes Janahan stand out is his unique combination of technical depth and product vision. With his engineering background, he not only understands what it takes to build stable and scalable products but also brings great ideas that are practical, intuitive, and user-friendly.
