LatviaWhat I'm looking for
I am a Senior Full Stack Developer with over 10 years of experience in building and modernizing complex software systems for SaaS-based, enterprise-class applications. My expertise lies in .NET and Angular, where I have successfully led significant migrations and developed tools that enhance user experience and operational efficiency. At Printify, I spearheaded an 80% migration from Backbone to Angular, which not only modernized our codebase but also improved developer velocity and maintainability.
Throughout my career, I have demonstrated a strong product-oriented mindset, collaborating effectively with cross-functional teams to deliver over 15 customer-facing features. I thrive in remote-first environments and am a strong advocate for clean code and best practices. My commitment to mentoring junior developers and driving knowledge-sharing initiatives has fostered a collaborative culture within my teams, ensuring continuous professional development and innovation.
