From automating 2D diagram analysis at Siemens to reimagining customer care for United Airlines, I’ve built products that solve real problems across industries. At Zinnia, I designed life insurance and annuity platforms, and today at Zaggle, I lead B2B spend management solutions that process crores in payments every month. Each step in my journey has been about one thing: turning complexity into products that scale with ease.

Zaggle

August 2023 - Present

Challenge: Corporates required a unified platform for handling payments, banking, and reconciliation.
My role: Oversaw the product lifecycle for Procure-to-Pay, Utility & Rental payments; developed reusable ERP connectors and integrated connected banking APIs.
Result: Onboarded over 30 top-tier corporates, achieving a 50% increase in MRR within six months; generated ₹12–15 Cr in revenue month-over-month.

Zinnia

Sep 2022 - August 2023

Challenge: Disjointed API access and manual handling of insurance processes.
What I accomplished: Created and initiated a centralized gateway (over 1,000 REST APIs) and streamlined policy workflows.
Results: API access improved by approximately 45%; the insurance policy processing timeline was shortened by 90%; production errors decreased from over 400 to fewer than 100.

Tata Consultancy Services

Jul 2016 - August 2022

Challenge: There was a high demand for support alongside minimal automation for travel customers.
Actions taken: I facilitated the development of products, conducted UX research, and created recommendation systems.
Outcome: The travel application attained a 99% satisfaction rate among customers and 100,000 active users in 10 different markets; machine learning recommendations decreased support workload by approximately 80% and saved around 20,000 hours of agent work every month.
