Mohammed Abdulla

Full-stack developer. I build products end to end — web, mobile, and the systems behind them — for clients and on my own. The client products have 160,000+ registered users between them.

Experience

Software Developer · National Research Council Canada

Sep – Dec 2025

Built and maintained internal tooling on Microsoft Power Platform — Power Automate flows, Power Pages sites and Dataverse models.
Migrated an existing internal site onto a newer platform version with no loss of availability to its users.

Software Developer, Survey Data Tools · Department of Fisheries and Oceans

Nov – Dec 2023 · Feb – Jun 2024

Built a metadata recorder in Angular and Electron that captures survey input and generates JSON metadata for downstream systems.
Delivered in an Agile team — daily stand-ups, Jira Kanban and sprint planning.

Software Developer, Geospatial Tooling · Department of Fisheries and Oceans

May – Aug 2022 · Jan – Aug 2023

Cut an internal file search from roughly twenty minutes to a few seconds by indexing file metadata into a database on a sync schedule, rather than querying Azure Blob Storage directly.
Built the search tool in Python and PyQt, and wrote the test suite covering the Caris Cloud API’s core request paths.
