Cut average API response time by ~75% by implementing Redis caching across banking platform APIs, reducing database query load during peak hours. Migrated long-running workflows into a dedicated BullMQ consumer service, now handling 2M+ records per day. Delivered secure, scalable backend services using TypeScript and Express.js, deployed on AWS EKS with S3 for storage and Scalyr for observability. Improved usability across multiple operational departments by building modern, responsive internal UIs with Next.js and Mantine UI. Turned operational requirements from product owners and business stakeholders into production-ready features in a cloud-native AWS environment.

Shipped 3 production microservices using Fastify and NestJS, sustaining up to 100 RPS with stable performance under real transaction load. Improved cross-service integration reliability across corporate banking workflows by building event-driven asynchronous pipelines with RabbitMQ and Redis to decouple service dependencies. Reduced processing time compared to prior synchronous implementations by developing and maintaining Go services for high-throughput background data processing. Reduced manual intervention in operational processes by automating recurring business tasks with scheduled jobs and background workers. Accelerated feature delivery across the corporate banking platform by building reusable frontend components with Next.js and Material UI. Improved overall system performance through code optimization, query tuning, and architectural enhancements.

Delivered scalable, maintainable RESTful and GraphQL APIs supporting multiple enterprise and web-based applications, with an emphasis on clean code. Improved application responsiveness at high-traffic endpoints by resolving critical API and database performance bottlenecks through query optimization and Redis caching. Served as a primary technical reference for data modeling decisions by designing and leading database schema design (ERD) for new applications. Improved code quality and development consistency by conducting code reviews for a 2-person backend team and establishing engineering standards. Delivered integrated business solutions across diverse client environments by collaborating with frontend engineers, GIS specialists, and project stakeholders.
