Engineering profile and resume Discuss a project LinkedIn

Open to senior and lead engineering opportunities across Canada: remote, hybrid or in office. Relocation considered.

Professional experience

Dependable systems, from API to operations.

I am a Senior Software Engineer at Condo Control, where I have worked since May 2019. My stack includes .NET Framework, ASP.NET Core, Azure, SQL Server, Entity Framework, and React/TypeScript with Vite. I build payment workflows and integrations, automate regression checks, review code, and mentor developers.

My Chemical Engineering and Data Science education informs how I approach system behaviour and evidence. I also build AI agent workflows for delivery and debugging, with explicit quality checks.

Services

Make critical systems easier to trust.

I help SaaS teams and agencies deliver dependable payments, integrations, and operational automation. Engagements start with a bounded problem, a clear output, and a practical next step.

Payment reliability review

A focused diagnostic of one payment workflow or integration, covering the paths where processor actions and application records can drift apart.

CA$2,500

fixed scope

Best for: SaaS teams preparing for a launch, migration, or scale-up—and agencies that need an independent review of a payment workflow.

Integration build or rescue

Hands-on backend delivery for a defined Stripe, external API, or data integration that needs to be shipped, repaired, or made easier to operate.

From CA$7,500

per project

Best for: Product teams and software agencies with a bounded integration project, stalled implementation, or payment workflow that needs recovery logic.

Service details

Reconciliation and quality automation

Practical SQL, API, and test automation that helps teams find mismatches, reduce repetitive checks, and protect critical workflows as they change.

From CA$1,500

per month

Best for: Engineering and operations teams spending too much time reconciling records, investigating mismatches, or repeating release checks.
