What I'm looking for

I seek senior engineering roles building scalable .NET/React cloud applications, mentorship opportunities, and a collaborative Agile environment focused on performance and user impact.

I am a senior software engineer with deep expertise in .NET frameworks, React, Angular, and cloud platforms including AWS and Azure. I design and deploy robust APIs and front-end solutions, leveraging multithreading and microservices to drive significant performance improvements.

I have delivered large-scale applications—Next.js front-ends serving over 1M users, React Native and mobile apps supporting 10K+ users at major events, and multiple .NET Core APIs—while maintaining high uptime and leading Agile teams to increase delivery speed by 25%.

I thrive on mentoring and knowledge transfer, having trained team members on Next.js and guided cross-functional teams through DDD and clean architecture. I seek opportunities to build scalable systems that improve user engagement and operational efficiency.
