Java & J2EE Development
Expertise in Java and J2EE (multiple versions after Java 8), including large-scale custom-built application development using Spring, Spring Boot, Web-Services, Micro-Services/Micronaut, and IBM WebSphere for enterprise-grade systems.
Microservices & Cloud-Native Architecture
Strong background in designing and implementing microservices using event-driven patterns (pub/sub, event sourcing), cloud-native application development, and deployment on multi-cloud platforms including AWS and Azure.
API Design & Integration
Proficiency in building and optimizing secure REST and GraphQL APIs for authentication, content management, analytics, and third-party integrations, as well as system integration using MuleSoft, Apache Kafka, Apache Camel, and SOA/ESB/EAI middleware.
Cloud Platforms (AWS & Azure)
Hands-on experience with AWS services (S3, Lambda, EC2) and Microsoft Azure for cloud migration, deployment, and scalable infrastructure management.
Databases & NoSQL
Working knowledge of NoSQL and SQL databases including MongoDB, PostgreSQL, LDAP, Hazelcast, Redis Cache, and ELK stack for data management and performance optimization.
DevOps & Build Tools
Practical experience with DevOps tooling including Maven, GIT, Kubernetes, Docker, Jenkins, JIRA, and CI/CD pipelines such as GitHub Actions for streamlined deployment and delivery.
Frontend Technologies
Familiarity with frontend technologies including React and NodeJS for supporting full-stack development and connecting frontend systems with backend APIs.
Apache Kafka & Messaging Systems
Experience with Apache Kafka for messaging, including creating topics and consumer groups, implementing exactly-once semantics (EOS), and reducing consumer lag through partition tuning and batching optimization.
Agile & Scrum Leadership
Experience leading Scrum teams, organizing Agile planning meetings, tracking progress using JIRA, and ensuring timely delivery of projects through structured sprint management.
NLP-Driven Automation & Analytics
Implementation of NLP-driven automation via REST APIs to analyse user interactions, detect anomalies, deliver real-time corrective recommendations, and support API-driven data workflows for analytics dashboards.

Project history
Developed backend systems with Spring, ORM and RESTful and GraphQL APIs. Created scalable microservices using event-driven patterns. Improved security for APIs, modernized legacy systems, improved database performance with MongoDB and PostgreSQL, implemented exactly-once semantics (EOS), and managed deployments using CI/CD tools like GitHub Actions and Docker.
Worked on Fusion Essence, a cloud-based core and digital banking solution deployed on Microsoft Azure and AWS Cloud. Responsibilities included MongoDB data management, AWS services (S3, Lambda, EC2), reducing consumer lag by 40%, troubleshooting production issues, implementing machine learning algorithms for payment processing forecasting, and using Jenkins pipeline for microservices deployment.
Led development for client DF/AMEX on a private student loan platform. Converted monolithic app to microservice architecture using Micronaut and Spring Boot, integrated messaging systems and GraphQL, developed RESTful APIs, worked with Kafka using Spring APIs, and improved delivery agility. Achieved 90% test coverage using Mockito framework.
