I’m a Senior Data Engineer with 4 years of experience across backend development, cloud-based data engineering, AI tools, and QA automation. I focus on writing clean, efficient Python code that delivers high-performance solutions across IVR, telecom, networking, and enterprise domains.

At Bounteous X Accolite, I engineered and enhanced SunLife IVR experiences on Amazon Connect. I developed and deployed AWS Lambda functions with boto3 for IVR call logic and Amazon Connect flow integrations, and I implemented authentication modules (LockedParty, webRegistrations, PreferredEmail) to improve security and reliability.

I built robust Python backend solutions at Capgemini for Cisco & Viavi, achieving 90% test coverage through Pytest automation. I reduced defects by 20% using static code analysis and improved application performance by 20% via root cause analysis, while optimizing AWS Lambda cold start latency through efficient packaging and provisioned concurrency.

I also contributed as a QA Automation Engineer, building Python/Pytest regression suites that reduced post-deployment bugs by 30%. My approach is end-to-end: CI/CD with Jenkins, API validation with Postman/Bruno, clear documentation, and continuous delivery practices aligned with Agile/Scrum/kanban.
