Staff engineer leading the design, architecture, and delivery of scalable backend systems supporting high-traffic, consumer-facing financial platforms. Drive technical direction across teams, own critical architectural decisions, and balance hands-on development with technical leadership and mentorship.

Key contributions include architecting white-label platform offerings under aggressive timelines, improving system reliability and performance at scale, and leading initiatives around security, IAM, and resiliency. Partner closely with product, infrastructure, and leadership to unblock execution and ensure long-term platform health.

I worked closely with stakeholders to resolve technical challenges and led architectural design meetings to facilitate cross-team knowledge sharing. I optimized the performance of a Spring Boot application by identifying and resolving CPU bottlenecks using VisualVM. Additionally, I architected and implemented an Identity and access management(IAM) module with KeyCloak to ensure backend SSO compliance. I engineered a cross-DC failover solution to improve system resilience by enhancing the Cassandra driver with a custom strategy.

I developed a custom in-memory caching solution to reduce external database and Redis calls, adopted a contract-first approach for API design to enable parallel development, built a secure Two-Factor Authentication framework, streamlined the user onboarding process to reduce friction, and migrated Spring Aspects to AspectJ for improved runtime performance.

As part of an agile team, I helped migrate an inventory update module from Tibco queues to Google Cloud, re-architected it to consume data from Kafka topics without disrupting domain objects, implemented a custom multi-threaded Kafka consumer with externalized partition offset storage, enabled timestamp-based recovery on consumer failures, and utilized Datastax Cassandra as the primary data store, integrating it through Datastax libraries.

I re-architected a monolithic transaction processing application into a microservices-based solution to improve scalability and maintainability, optimized data migration performance using ThreadPoolExecutor and object locking to prevent contention, built a Spring Boot microservice to extract data from Oracle DB, convert it to JSON, and publish it to Kafka, and developed a library to facilitate seamless migration from RDBMS to Kafka topics based on domain objects.
