What I'm looking for

I'm looking to continue building and modernizing enterprise, payroll, financial services, or banking platforms, solving complex integration and business-rule challenges with Agile international teams.

I'm building and maintaining features for PaymentEvolution's Canadian payroll and financial services platform, using C#, ASP.NET Core, React, SQL Server, and APIs. I've delivered company onboarding workflows spanning setup, payroll, policies, ownership, directors, beneficial owners, and signing.

I modernize legacy WebForms and .NET Framework applications into ASP.NET Core, React, and REST-based services. My work includes IdentityServer and Duende IdentityServer integrations, OAuth 2.0, OpenID Connect, JWTs, identity verification, banking services, ePay, microdeposits, and Interac flows.

Across Intermix, Elixir Software, and UCI-CEIGE, I've developed microservices, banking modules, financial systems, SQL Server reporting, and web migrations from desktop applications. I enjoy solving complex business rules with international Agile teams through code reviews, testing, documentation, and cross-team integration.
