I am a Senior Software Engineer specializing in distributed systems architecture, real-time collaboration platforms, and scalable SaaS infrastructure.
My work focuses on designing and implementing software systems that improve coordination, reliability, and productivity in modern engineering environments. I have experience building and modernizing high-traffic digital platforms, enterprise-scale web applications, and real-time multi-user systems.
I am also the creator of StoryPoker, a live SaaS collaboration platform designed to support agile estimation workflows for distributed software engineering teams.
