Designed, developed, and implemented scalable metadata storage service using Java SpringBoot, AWS Lambda, and S3, which hosted the images of 10,000 rental properties with 99.99% availability every month. Currently working with a team of 11 members contributing towards providing the robust microservice-based application for the warehouse rental management system. Implemented Kafka as streaming and queuing services for asynchronous message passing between microservices.

Using Java Spring Boot & Kubernetes, created secure and Robust REST APIs for the order management system, allowing customers to generate revenue reports. These APIs handle around 1 million update calls per hour. Acquired significant proficiency in SQL, stored procedures, functions, and triggers through extensive experience with MS SQL Server and PostgreSQL databases.Developed and executed robust integration and user acceptance tests to ensure system reliability and user satisfaction.Additional

Utilized Java, Spring Boot, nodeJs, JavaScript, and AJAX(asynchronous Calls) to create an end-to-end microservice-based distributed System for IGRS (Indian state Government of Tamil Nadu) which seamlessly allows the search/index of chit funds for 71 million people. Utilized Spring boot to create the backend Authentication and CRUD REST APIs. Developed efficient data management APIs using object-oriented principles and Hibernate to persistently store the object-styled data in PostgreSQL. Led the architecture design of the birth/death certificate issuance and implemented the POC. Created the authentication and authorization service for secure access to the public APIs using Oauth 2.0 and Spring Boot. Also enabled the service to provide role-based access. Created the terraform scripts to automate the deployment of the application on AWS.Enhanced the GitLab CI pipeline runtime by optimizing the sequences and Jenkins artifacts re-using across various pipelines. Resulted in a 20 percent S3 storage cost and an 18 percent run time improvement.Creating optimized ETL queries using Python, Hadoop, and PySpark to monitor the performance of the services and find the bottleneck components of indexing. Prioritized complex performance issues and resolved them during on-call rotations within tight deadlines.

Contributed to a team of 5 towards the development of the CRM tool which allows the customer to store, update, and periodically delete the sale records through Restful web services.Developed the middleware transform module using Java to store the formatted data in MySQL.

Contributed to a team of 3 towards the development of the backend component of inventory management tool, which allows the efficient storage and retrieval/lookup of items in inventory. Enhanced the lookup performance by 12% fixing the SQL schema and queries.
