Led the migration of legacy Java batch processing systems to modern, scalable Scala pipelines using Apache Spark on Google Cloud Dataproc, enabling processing of over 500 million transactions daily and improving throughput by 40% through custom partitioning and lazy evaluation. Designed and deployed cloud-native microservices with Akka HTTP (Scala) and Spring Boot (Java) on Google Kubernetes Engine (GKE), supporting real-time fraud detection and alerting for financial applications. Architected and maintained event-driven architectures using Apache Kafka and Kafka Streams, integrating Java and Scala services for seamless, scalable data flow across distributed systems. Implemented robust CI/CD pipelines for GCP-based deployments using Jenkins, Docker, and Kubernetes, automating testing, building, and zero-downtime releases for RESTful microservices. Developed and maintained RESTful APIs using Spring Boot, JAX-RS, and Akka HTTP, enabling secure, scalable integration between frontend, mobile, and third-party applications. Implemented secure REST endpoints with JWT-based authentication and OAuth 2.0, ensuring compliance with financial data privacy standards and protecting sensitive data. Built versioned REST APIs with backward compatibility, supporting multiple client applications while minimizing production service impact and ensuring seamless upgrades. Documented and managed APIs with Swagger, facilitating clear API documentation, streamlined onboarding, and efficient testing for internal and external stakeholders. Applied advanced Scala functional programming paradigms, including case classes, pattern matching, monads, and immutability, to deliver safe, maintainable, and high-performance code for distributed data processing. Mentored and trained junior developers in Scala best practices and functional programming concepts, elevating team productivity and code quality.
