I am a software engineer with 4+ years of experience building scalable distributed systems, cloud-native microservices, and AI-driven fintech applications. I specialize in Java, Spring Boot, Python, Node.js, REST/GraphQL APIs, and AWS (EKS, Lambda, S3, API Gateway), Kubernetes, Docker, Terraform, with hands-on experience in event-driven architectures using Kafka and Redis, and microservices patterns like Saga and Circuit Breaker. I also work with RAG-based AI systems, vector databases, LLM applications, and secure system design (OAuth2, JWT, RBAC, encryption). I’m adept at CI/CD automation and observability tooling to ship reliable software at fintech scale. Beyond coding, I’m a collaborative teammate who loves solving complex problems, designing robust architectures, and delivering value quickly while maintaining quality. I’m open to relocation and eager to contribute to innovative fintech and cloud-native projects with a focus on security, scalability, and measurable impact.

Work Experience

Software Engineer at Paypal
September 1, 2024 - Present
Architected a production-grade RAG-based AI support system using LangChain, OpenAI APIs, and FAISS/Pinecone vector databases to support 10K–15K queries/day with peak throughput of 120–180 QPS across distributed channels. Built scalable microservices in Java/Spring Boot exposing REST and GraphQL APIs; implemented an LLM-driven agent for dispute classification and integrated PostgreSQL/MySQL pipelines. Established real-time event processing with Apache Kafka and Redis caching; containerized services on AWS (EKS, Lambda, S3, API Gateway) with Terraform, enabling faster deployments. Implemented CI/CD pipelines with Jenkins and GitHub Actions, automated testing (JUnit, Jest) and rollback strategies; set up observability with Splunk and CloudWatch.
Software Engineer at Accenture
October 1, 2020 - August 31, 2023
Developed a highly scalable digital banking application using Java, Spring Boot, Hibernate, and REST APIs, delivering secure core banking features with 99.9% uptime. Implemented OAuth2, JWT, and AES-256 encryption with TLS 1.2, improving API security and risk posture. Built a component-based frontend with React and Redux, integrated with backend microservices (Node.js/Spring Boot), reducing page load latency by 40%. Designed and implemented a legacy-to-modern integration layer with API gateway orchestration and service mesh for secure interoperability. Engineered real-time, high-throughput transaction processing via event-driven microservices, Redis caching, and MongoDB, handling 10,000+ concurrent transactions/min with sub-200ms latency. Automated CI/CD pipelines with Jenkins and GitHub Actions for AWS deployments, and developed automated testing frameworks (Jest, Mockito) achieving 85%+ code coverage.
