Experience
Senior Software Engineer
Jan 2025 — Present · Hyderabad, IN
As a Software Engineer in Test at Capgemini, I specialize in designing and executing robust test strategies for web and API applications. I create detailed test cases from requirements, ensuring strong functional coverage and identifying edge cases across modules. I collaborate closely with developers, designers, and product managers to verify system behavior and execute manual test cases using JIRA and Azure Boards.One of my recent contributions is a custom-built Financial Reconciliation Engine that automates comparison of timesheet and billing data to flag mismatches. It brings down the recon time from 3–4 days to around 10 seconds. The first version is complete and currently undergoing review and validation.Outside of work, I build independent automation tools—like a high-speed IRCTC ticketing bot and a CNN-powered CAPTCHA solver—exploring ML, browser automation, and scalable scripting.With experience in Selenium, RestAssured, Playwright, and Postman, backed by a strong DSA foundation, I focus on creating tools and solutions that make testing smarter, faster, and more reliable. I believe QA isn’t just about testing—it’s about building systems that prevent failure, not just detect it.
