What I'm looking for

I seek a collaborative, agile team where I can design scalable data and mobile solutions on Azure, lead migrations, mentor engineers, and improve system performance and reliability.

I am a collaborative software engineer with more than 8 years of experience designing and delivering solutions across multiple industries, focused on reliable data delivery and system performance.

I have led migrations of legacy pipelines to scalable OT data platforms, designed event-driven high-frequency data delivery solutions, and automated backfill processes to reduce operational costs.

I build end-to-end RESTful API and mobile solutions using C#, .NET, Xamarin, TypeScript/Angular, and Azure services, and I apply MVVM and offline-online sync patterns for robust mobile experiences.

I mentor engineers, conduct code reviews, and promote agile development practices to improve code quality, application stability, and team ownership while optimizing security and performance in production systems.
