About Me

$whoami

I'm a Software Engineering undergraduate at the University of Moratuwa with hands-on experience in AI systems, cloud infrastructure, and scalable full-stack applications.

Currently working as an Associate Software Engineer - AI at Bayseian (UK), developing AI-driven MVP solutions including PII redaction systems and semantic data handling workflows using AWS Bedrock and LLM-powered pipelines.

I'm passionate about open source, having published pyvalidx on PyPI and a form validation library on npm. I also enjoy writing technical articles on Medium about SignalR, CI/CD, and AI topics.
