Led the development of scalable microservices and full-stack applications, significantly enhancing system performance and security within an agile environment.

• Increased service throughput by 50% through re-engineering synchronous processes to asynchronous using Kafka and Reactive Programming.
• Reduced React.js front-end application build time by 15% through strategic refactoring and upgrades on Node.js.
• Achieved 100% test coverage for Spring Boot applications using Testcontainers, significantly improving reliability and reducing production bug rates.
• Implemented OpenTelemetry for comprehensive tracing and observability across all services, enhancing visibility into key metrics like throughput and failure rates.

Developed and optimized robust software solutions, focusing on performance enhancements, security improvements, and efficient data processing.

• Revamped PDF generation by integrating Thymeleaf templating, reducing code cognitive complexity by 40% while processing nearly a million bank statements efficiently.
• Reduced user dashboard processing costs and improved loading speed by 95% through pagination and an aggregator pattern for efficient data handling.
• Introduced dynamic query generation at runtime, eliminating static SQL strings and mitigating injection vulnerabilities, resulting in an 80% reduction in query size and improved response time.
• Maintained and upgraded existing Spring Boot applications, resolving critical CVE vulnerabilities and enhancing security postures across services.

Recognized for Exceptional Performance during tenure at Optum.
