What I'm looking for

I'm seeking a senior engineering role where I can lead end-to-end web app development, improve delivery pipelines, and work with a collaborative team focused on performance, testing, and scalable cloud solutions.

I am a Full Stack Engineer with 7+ years building production systems focused on high-quality web applications using React, TypeScript, and .NET. I lead with testing, performance, and reliable delivery while maintaining strong cross-team collaboration.

I've worked across Azure, Python/FastAPI, Node.js, and multiple databases (PostgreSQL, MongoDB, Cosmos DB), owning architecture and integrations for cloud platforms and services. I have hands-on experience implementing PWAs, service workers, and route-based code splitting to boost performance and offline capability.

As a tech lead and engineer at Tridius and previous roles at Microsoft and Intel, I established CI/CD pipelines, delivery standards, and improved reliability and latency through API management and infrastructure automation. I also built big-data analysis pipelines and production dashboards to drive actionable insights.

I bring a practical, results-driven approach—comfortable designing end-to-end solutions, automating workflows, and shipping scalable systems. I'm passionate about accessible, responsive design and continuous improvement in engineering processes.
