About

A pragmatic engineer who ships.

I'm a full-stack software engineer with 7+ years of experience building and shipping production web applications, currently working as an independent contractor based out of Sudbury, ON.

My main ongoing engagement is full-stack work for a US-based subscription e-commerce company: a ColdFusion application backed by a MySQL database with millions of rows. I do schema design, query tuning, REST API integrations, internal dashboards, and a lot of feature work that gets shipped end-to-end. I'm also leading the integration of AI into their build-and-ship pipeline.

Alongside that, I take on shorter-term front-end projects with clients in Canada, designing and building responsive websites from scratch.

Before going independent, I spent ~4 years at Echologyx in Dhaka on the conversion rate optimization side, shipping 50+ A/B tests across enterprise client sites and building internal tooling. I'm finishing my M.Sc. in Computational Sciences at Laurentian University and deepening my Java, Spring, and modern JS framework skills.
