Software Development Engineer 2 at WEX INC
September 1, 2025 - PresentLed the decomposition of a 30-year-old, 25-module monolithic payments platform (IFCS) into AWS-based microservices, managing 3 engineers and driving end-to-end architecture and execution, eliminating critical performance bottlenecks, reducing release cycles from months to weeks and improving deployment scalability. Architected and built a high-throughput Pricing Engine and Pricing Configuration Service from scratch using Java 21, Spring Boot 3, and AWS, replacing a critical monolith module responsible for complex multi-party pricing, surcharges, fuel rebates, merchant agreements, and tax calculations. Reduced pricing computation latency by 10× (1.5s → 150ms) through deep performance engineering, including schema redesign, Redis caching, and parallelized computations using Java 21 virtual threads, significantly improving scalability and responsiveness for high-volume transaction processing. Migrated 20M+ legacy pricing configurations with zero downtime using a fault-tolerant Kafka-ba
Senior Software Engineer at Samsung Research Institute
August 1, 2023 - August 1, 2025Built a Kinesis-based payment queue microservice using Java, Spring Boot, and gRPC to process 10M+ peak-hour payment events with ordered loanId partitioning, consumer-side deduplication, and race-condition prevention, eliminating duplicate payment callbacks and significantly reducing downstream service overload during high-traffic periods. Engineered a multi-account device orchestration microservice managing 6M+ active Samsung devices, introducing intelligent Samsung KNOX account routing, in-memory TPS tracking, and migration-driven scaling to eliminate systemic rate-limit failures and improve reliability during peak onboarding. Re-architected delinquency notification delivery from a once-daily batch workflow into an hourly event-driven pipeline using EventBridge and AWS Batch, enabling near real-time repayment reminders for 17M+ notifications/day. Migrated the payment queue infrastructure from AWS Kinesis to GCP Pub/Sub to enable multi-cloud availability for non-AWS regions, improving
Software Engineer 1 at Samsung Research Institute
August 1, 2023 - PresentImplemented a Kinesis Queue microservice using Java, Spring Boot, and gRPC to resolve concurrency and duplicate callback issues, handling over 10 million peak-hour payments. Developed a device-specific microservice managing over 6 million active devices with dynamic request routing and real-time tracking, ensuring scalability. Migrated services from AWS Kinesis to GCP Pub/Sub for non-AWS regions and upgraded multiple microservices from JDK 8 to JDK 17, enhancing performance, maintainability, and cross-platform compatibility. Optimized a notification pipeline to deliver over 17 million notifications daily within 10 hours using batch processing and AWS batch queues, ensuring reliability and compliance with partner TPS limits.
Software Engineer Intern at Samsung Research Institute
July 31, 2022 - August 4, 2025Developed a C++ application to optimize storage of relational data in Redis, reducing query latency by 50% (from 90ms to 40ms), significantly improving data retrieval performance. Automated partner dashboard tasks using Selenium to secure loaned devices in absence of a partner API, enabling crucial business operations within the organization.
