About

I've spent the last four years working on payments infrastructure, mostly on distributed backends that move real money for real users. It's the kind of work where correctness matters a lot, especially when the network doesn't cooperate. I'm currently at Techmojo on project, a modular wallet and payments platform running 30+ Spring Boot microservices on AWS EKS. A lot of my work sits in the layer where things tend to get tricky: card network integrations (Mastercard MDES, Visa VTS, Network International), payment gateway abstraction with HMAC-SHA256 webhook signature validation, idempotent APIs keyed on partner request IDs through Redis SETNX, and Resilience4j fixed-delay retries with dead-letter queues for failure recovery. Some of the deeper technical work I've been part of: Kafka Streams pipeline processing around 5K events/sec across 24 partitions, running effectively-once semantics for payment reconciliation OAuth2 authorization server backed by a shared security library used across the microservice fleet, plus RBAC, Microsoft SSO, and Azure AD integration on the org-management service (dropped access-support tickets 35%) KYC/AML workflow with HyperVerge, UAE Pass, and AWS KMS, cutting manual review load 50% Custodial crypto wallet service integrated with Aquanow for BTC and multi-asset flows, with parent-reference mapping and full Hibernate Envers audit trails p99 latency work on payment APIs, 380ms down to 245ms through composite indexing, multi-tier caching (Redis + local), and query rewrites Kafka-based notification platform delivering 45% higher throughput under peak concurrency 90% test coverage on critical flows using JUnit, Mockito, Testcontainers, and WireMock, which has helped catch a few bugs that slipped past code review Before Techmojo I worked on a large-scale Meter Data Management System at Landis+Gyr in Java/Spring Boot with MySQL and Oracle, and did an internship-to-full-time stint at Samsung SDS building enterprise web apps and improving CI/CD. B.E. in Electronics and Computer Engineering, Thapar Institute (2018 to 2022). On the side, I try to keep my fundamentals sharp: CodeChef 4★ with a 1800+ rating, and 400+ LeetCode problems across DP, graphs, trees, and concurrency. Things I care about: distributed systems that stay correct under load, idempotency and effectively-once semantics that hold up when the retry storm hits, observability that actually helps when you're debugging at 2am, and code that's easy to read for whoever picks it up next.
