What I'm looking for

I seek a senior engineering role where I can build scalable web platforms, mentor teams, influence architecture, and deliver measurable business impact in a collaborative, product-focused environment.

I am a senior fullstack engineer with over a decade of experience delivering high-performance, user-focused web applications and scalable APIs. I specialize in Node.js, Express, and React.js and excel at integrating complex business logic into responsive, data-driven UIs.

At Trustware I designed and deployed Node.js/Express APIs for a blockchain wallet security platform, added JWT authentication and role-based access control, and built real-time transaction monitoring that reduced incident response time from hours to minutes. I also introduced automated regression testing with Playwright and Jest, cutting post-release defects by 35%.

Previously at Forecastr and Intuit I led migrations to Next.js with server-side rendering, implemented advanced financial modeling features, integrated QuickBooks and Xero APIs, and resolved CI/CD bottlenecks to improve uptime and developer onboarding. I have built low-latency trading systems with Redis, Kafka, and AWS and integrated ML models to improve predictive signals and automate workflows.

I bring a pragmatic, results-oriented approach to engineering, prioritizing maintainability, measurable business impact, and cross-functional collaboration to turn product ideas into reliable solutions that scale.
