What I'm looking for

I'm looking for a software or database development role where I can build reliable MySQL and Python solutions, solve application issues, contribute to clean maintainable code, and continue learning emerging technologies.

At TCS, I developed, maintained, and optimized MySQL databases while supporting reliable software delivery. I wrote complex SQL queries, joins, stored procedures, and reports to support business operations.

I use Python for automation and backend tasks, diagnose application and database issues, and contribute to database backup, recovery, and performance tuning. I work closely with development teams on features, enhancements, code reviews, and deadline-driven delivery.

I also built an Employee Management System and a Database Reporting Tool using MySQL, Python, HTML, CSS, and MS Excel, with a focus on CRUD operations, query optimization, automated reporting, and data analysis.
