As a Talend Developer, I was instrumental in the seamless transfer and upgrading of services, guaranteeing optimal data integration across projects. My contribution has helped to optimize data workflows, improve integration capabilities, and ensure the dependability of information exchange operations. I thrive on exploiting Talend's tremendous capabilities to create efficient and scalable data integration systems.

I use my skills in data extraction, translation, and visualization from a variety of projects to support data-driven decision-making as a Data Analyst at Pulse. Design of Data Warehouses and ETL Development Designed and constructed a strong Star-schema Datawarehouse to improve data retrieval efficiency. Using Python Pandas, data was extracted seamlessly from the Odoo ERP (PostgreSQL) and Airtable APIs (JSON). Complete ETL operations were completed using Airflow, automating data workflows to improve operational effectiveness. created perceptive reports and enabled Power BI data visualization. Development of ETL and Process Improvement Developed ETL processes and led the way in removing data from Sage SQL/PL-SQL stored procedures (SQL Server). Python Pandas was used for efficient data loading and transformation procedures. used QlikSense to implement data visualization techniques and give stakeholders comprehensible insights. Initiated and led project adjustments and revisions to ensure data correctness and completeness. Extracting and Transforming Data Managed data extraction operations, including collecting updates from PostgreSQL and using Zato to consume messages over RabbitMQ. Data transformation and loading tasks were completed with Python Pandas, assuring data integrity and consistency. Throughout these projects, I've showed expertise in utilizing sophisticated data analytics tools and technologies to extract important insights, improve reporting capabilities, and contribute to overall business intelligence strategy.

As a Java Developer, I have helped to design, create, and deploy strong and scalable programs from start to finish. Here is a summary of my primary responsibilities: Design, development, and deployment. Managed the whole software development life cycle, from ideation and design to coding, testing, and deployment. Collaborated with cross-functional teams to collect requirements and transform them into scalable, maintainable code. Spring Boot may be used to provide APIs that are efficient and robust for backend services. RESTful APIs were implemented to provide easy communication between the application's many components. Proficient in designing intuitive and responsive user interfaces with Spring Web MVC. Designed and deployed dynamic web pages to provide a seamless and interesting user experience. Utilized SQL Server for effective database administration, including storage, retrieval, and management. To match application needs, I created complicated SQL queries and enhanced database performance.
