What I'm looking for

I’m looking for remote contract work where I can lead .NET/Azure engineering, design microservices and delivery pipelines, and keep production stable—while mentoring teams and shipping measurable improvements.

I’m a Senior .NET Engineer with 10+ years building and shipping production software across SaaS platforms, digital agencies, and enterprise systems. I focus on designing reliable architectures, de-risking decisions early, and keeping delivery moving with high engineering standards.

At Avant Mutual, I designed microservices architecture, introduced Azure Service Bus, and led JWT migration across all SPAs. I managed an offshore team of 5 through major platform refactors and a customer migration completed with zero production incidents, staying hands-on through code reviews, architectural input, and solution investigation.

As a Delivery Manager and Software Development Manager, I’ve owned end-to-end delivery across engineering, QA, and product—accountable for release pipelines, multi-environment delivery, and engineering execution. I led practical improvements like migrating regression automation from Selenium/SpecFlow to Playwright, stabilising environments, and driving technical debt reduction that cut active production bugs from 8–10 per sprint to 2–3.

I’m also at my best guiding teams through complex platform initiatives: mentoring engineers, coordinating cross-service dependencies, and using Azure patterns to improve consistency and reliability. I’m available for remote contract engagements globally, especially where I can combine .NET engineering depth with leadership, delivery rigor, and measurable outcomes.
