Who you'll be working with

I'm Dmitry — a senior software engineer based in Montreal with 16+ years of experience building production systems. I've worked with teams at eBay, Ubisoft, and Multidev Technologies, and now I help businesses directly as an independent consultant.

I take projects from initial conversation to production deployment. You work with me directly — no account managers, no handoffs, no surprises.

I had the opportunity to work with Dmitry for many years, both as a fellow developer and as a manager. He has always delivered quality products, handling projects from the specification-gathering to support. His facility in learning ensured the right technology was used for each project, and was able to convert legacy projects inherited from other developers into modern ones. He 'owns' his projects well from start to finish. Over the years I have been impressed with how user friendly his UI has been, while at the same time maintaining a solid back-end. Replacing him has been difficult, and any employer would be lucky to have him!
