About Me

Committed to quality,
driven by precision

I am a detail-oriented Associate Software Quality Assurance Engineer with hands-on experience in digital banking and fintech environments, seeking to advance into a QA Engineer role. My journey began as an intern at Commercial Bank of Ceylon in collaboration with ORYSYS Limited, where I immersed myself in the full Software Testing Life Cycle across real-world banking applications.

Over two years, I have tested mission-critical platforms across Sri Lanka, Bangladesh, and the Maldives — validating complex integrations, conducting rigorous API and regression testing, and collaborating closely with developers and business analysts to ensure every release meets the highest quality standards.

Holding an ISTQB Foundation Level certification and a BSc (Hons) in Information Technology from SLIIT, I bring both theoretical grounding and practical expertise to every project I undertake.
