I'm a Staff Researcher at Huawei Canada, helping build and evaluate AI agents and foundation models for software engineering. I have a Ph.D. in Electrical and Computer Engineering from McGill University, an M.A.Sc. from the University of British Columbia, and a B.Sc. (Hons.) from the University of Moratuwa.

I've spent 15+ years in research and software engineering, with roles at Microsoft Research, Fortinet, WSO2, and Wise Systems. Along the way, I've built developer tools, worked on security and logistics software, and helped enterprise customers worldwide take integration solutions from requirements to deployment.

My research appears in ICSE, TSE, TOSEM, FSE, and ASE, and has received an ACM SIGSOFT Distinguished Paper Award (ASE 2025) and a Best Full Paper Award (ESEM 2015).

I've been invited to review papers for leading venues including ICSE, TSE, and TOSEM. I also give occasional lectures on Software Engineering and AI at universities, developer conferences, and bootcamps. I have co-advised 12 students on published research. Outside work, I enjoy reading and contributing to open source.
