I build platforms that make other people faster, in domains where being wrong is expensive.
Ten years across Microsoft, Amazon, Paytm, and REVE Systems. Distributed systems, enterprise data security, and the seams between teams that nobody else owns.
A decade of shipping systems where mistakes are expensive: payments, fraud, and now enterprise data security.
Technical lead for a program unifying two Purview data loss prevention enforcement stacks onto a single policy platform, spanning four engineering organizations and three product surfaces, delivered from public preview through worldwide General Availability. Sole owner of Administrative Units support for SharePoint Online, shipped world wide. Also the team's security champion: replaced high privilege access tokens with scoped service identities and led a certificate authority migration with zero customer visible downtime.
Owned invoice payment compliance end to end. Rearchitected the central view tracking invoice states to a 90% SLA, then built a rule engine that turned ETL queries into a domain specific language, with a self serve interface so customers could write their own rules instead of filing tickets. Auto resolution rose 30%. Also introduced idle EMR cluster auto termination, cutting infrastructure costs 23%.
Built fraud prevention logic for Cancellation Protect that cut fraudulent activity 25%, alongside demand driven pricing based on travel and booking time. Authored an integration framework that cut insurance partner onboarding time 60%, bringing on 12+ partners in two months. Later built the onboarding engine behind the Paytm for Business platform.
Built a two factor authentication system for B2B customers spanning CLI terminal and web auth, then packaged the web login flow as a standalone SDK so other teams could integrate it without understanding the internals, cutting unauthorized access attempts 40%. Also led an adaptive payment gateway integrating PayPal and CCAvenue with automatic country based routing, lifting successful transactions 20%.
Assisted the team in formulating client proposals and gained a working understanding of business analytics.
Studied and implemented WEP and WPA attacks and their variants under Dr. Goutam Paul, alongside a project on practical crypto and security tools under Mr. Vijay Kumar.
A few of the harder problems, in more depth than a resume bullet allows.
Two separate enforcement stacks protected the same enterprise data through different rules, different APIs, and different rollout paths. I led the technical program that unified them onto a single policy platform, coordinating across four engineering organizations and three product surfaces, and drove the rollout from public preview through worldwide General Availability into Government Cloud.
Defect tagging on disputed invoices meant hand writing ETL queries, a job only engineers could do. I designed a domain specific language that expressed the same logic declaratively, then built a self serve interface so customers could write and test their own rules without filing a ticket.
As my team's security champion, I owned the security and compliance backlog end to end: replacing high privilege access tokens with scoped, forwardable service identities across two platform workloads at zero regression, and serving as directly responsible individual for a service wide certificate authority migration.
A two factor authentication system built for one product became genuinely reusable once I packaged its web login flow as an SDK, spanning both CLI terminal and browser based authentication. Other teams could drop it in without understanding the internals.
Outside of shipping systems, I shoot photographs. It's where I learned that framing is most of the problem.
Two notes from the mentors during my first internships, before any of the rest of this page existed.
Your contributions during the 2 month internship were really noteworthy and commendable. I wish you all the success in your future years in education and going forward.
Ankur is a very enthusiastic programmer and has the capability of quickly understanding problems. He likes to explore new things. I wish him all the best in his future.
