Summary

Developed scalable and secure APIs to facilitate seamless data exchange across multiple platforms and partner systems. These APIs ensured high availability and robustness in handling sensitive transactions. Engineered microservices focused on user session management, rate limiting, and identity workflows. This improved system reliability and provided a smoother user experience across applications. Built and optimized ETL pipelines to ingest and transform large volumes of JSON data from cloud-based data lakes into relational databases. This enabled advanced analytics and accurate reporting for business insights. Integrated CRM APIs to synchronize data in real time, enhancing collaboration and operational efficiency across business units. This integration helped maintain up-to-date customer records and improved workflows. Modernized legacy SOAP services by refactoring them into lightweight, high-performance REST APIs. This transition reduced technical debt and significantly improved system response times. Automated end-to-end CI/CD pipelines using industry-standard tools, enabling seamless containerized deployments on orchestration platforms. This automation increased deployment speed and reduced manual errors. Implemented Role-Based Access Control (RBAC) policies to enhance security and ensure compliance with internal and regulatory standards. This strengthened the system's security posture and protected sensitive data. Leveraged monitoring and logging tools such as ELK Stack, Prometheus, and Grafana for comprehensive application observability. These tools enabled rapid detection and resolution of production issues. Collaborated closely with cross-functional teams on API design, error handling, and system architecture to drive project success. This collaborative approach fostered innovation and improved overall system quality. Mentored junior developers, conducted thorough code reviews, and supported incident response and post-mortem analysis. These activities helped maintain high code standards and operational excellence. Delivered robust backend solutions emphasizing scalability, security, and maintainability. This experience ensures readiness to tackle complex enterprise challenges in demanding environments.
