Project : Crime Management Program - Crime management program is a web application to digitise the Jurisdiction System in the UK.

• Led the transformation of a web application into a microservices architecture, utilizing Java, Postgres, and Azure services (Api Management, Azure Functions, Azure Blob Storage, Azure Kubernetes Services) along with Docker. Implemented CQRS principles and Event Sourcing, enabling efficient handling of millions of global users and processing 30-50K requests per second.
• Designed and built an in-house data processing tool using Java, Kafka, PostgreSQL, and Apache Guava APIs for data modeling. Achieved a remarkable 98% reduction in client reporting time by streamlining data from external services.
• Created a streamlined data processing tool that improved data indexing and real-time monitoring using Elasticsearch, Kibana, and Logstash
• Implemented automated API test suite covering 90% of critical endpoints, resulting in a 50% reduction in manual testing time and early defect detection.
• Integrated API tests into the CI/CD pipeline, ensuring that all new code changes were automatically validated, leading to a 20% reduction in production defects.
• Led the upgrade of multiple microservices from Java 1.8 to the latest version (Java 17) by addressing compatibility and modernization challenges.
• Managed the transition from Vagrant to Docker and orchestrated deployments on Azure Kubernetes, overcoming configuration and deployment complexities.
• Ensured a seamless migration, minimizing disruptions and enhancing the team's efficiency.
• Provided technical leadership and mentorship to junior team members, sharing expertise in architectural best practices, code optimization, and technology upgrades ,code reviews.

Project Summary: Transportation Management Web Application
The Transportation Management Web Application is a comprehensive system designed to streamline and optimize the management of a company's fleet of drivers and trucks. This web-based solution encompasses various functionalities critical to efficient transportation operations:

• Implemented mechanisms to integrate real-time data sources for traffic updates and fuel pricing e.g., Google Maps API or custom algorithms) for calculating the shortest and most efficient routes.
• Contributed to the development of route optimization algorithms for the shortest and most efficient delivery routes.
• Improved the user interface to provide drivers with intuitive route guidance and load management features.
• Collaborated with QA teams to conduct testing, identify and address bugs, and ensure the application's reliability.
• Ensured the route planning system could scale horizontally to handle increased traffic and route requests efficiently.

Project : Labor Management System - LMS serves as a vital tool for optimizing labor resources, enhancing employee productivity, and streamlining warehouse operations like attendance tracking, performance metrics, warehouse Area Allocation, Salary Structure Management, access control etc.

• Involved in the migration of a monolithic LMS application to a microservices-based architecture ensuring uninterrupted operation of core LMS functionalities during the migration process by implementing careful scoping and testing strategies to prevent disruptions to critical features.
• Implemented caching techniques strategically within the microservices architecture to optimize data retrieval and improve system performance.
• Utilized Docker containers for database management and testing
• Collaborated closely with cross-functional teams to align the migration with business objectives and requirements.
• Provided guidance and mentorship to team members throughout the migration process.
• Created documentation outlining the microservices architecture, deployment procedures, and best practices.
• Facilitated knowledge sharing sessions with team members with expertise in microservices.
• Designed the services to be scalable and resilient, allowing the LMS to handle increased workloads and maintain operational stability.

Project : Smart Catalog - To view and edit a N tier application using cloud services.

• Designed and developed a dynamic Smart Catalog Web Application with Java backend and React.js frontend.
• Integrated RapidJs for graphical representation, aiding clients in selecting cloud services for N-tier applications.
• Responsible for complete service development and deployment in production
• Participating in discussions with team to clarify the requirement.
• Responsible to improve the code Quality.
