Developed a Financial Portfolio Management System for Citi Bank, enabling portfolio managers to track investments, analyze transactions, and gain real-time insights. The system featured a modern tech stack, with the front-end built using HTML5, React.js, TypeScript, JavaScript, and Redux for a responsive and dynamic user interface and the back-end was powered by Node.js, Express.js, and integrated with Node.js-based frameworks such as NestJS for structured microservices and Mongoose for MongoDB integration. The system leveraged a range of Azure cloud services for scalability and security, including Azure App Service for hosting, Azure Functions for serverless APIs, Azure SQL Database for data storage, Azure Blob Storage for managing files, and Azure Key Vault for securing sensitive information. The architecture was microservices-based, containerized with Docker, orchestrated with Kubernetes, and CI/CD pipelines ensured smooth and automated deployment.o The front-end of the application can be developed using HTML5, CSS3, JavaScript, AngularJS, and jQuery that communicate with the back-end via RESTful APIs. I utilized Node.js for creating serverless REST APIs using Azure Functions, enabling scalable and efficient back-end processing. o Integrate Node.js Azure Functions with other Azure services such as Azure Cosmos DB, Azure SQL Database, Azure Blob Storage, a manage secrets, and store configurations.o Developed data pipelines & managed data processing tasks using Databricks and Snowflake also Conducted complex data querying, filtering, aggregation, and joins on relational databases such as MySQL, Oracle, and SQL Server.o Developed and maintained ETL pipelines using Java, SQL, Hive, Pig, Azure services, and Python to transform and load data from disparate sources into NoSQL databases, data warehouses, and data lakes. Utilized Azure Data Factory, Blob Storage, Synapse Analytics, and Python libraries for efficient data processing and integration.
