Top SchoolJacek Galanciak is a Lead Engineer with 16 years of experience building scalable web systems and shaping software architecture across startups and enterprise customers.

As a co-founder and sole engineer on earlier projects he designed and automated entire platforms, APIs and DevOps workflows until they ran passively, and now drives architecture and delivery at a YC-backed startup serving enterprise clients. He prioritizes sustainable developer productivity and domain-driven design, pairing hands-on coding with process and continuous delivery improvements. Based in Łódź, Poland, he balances a focus on enterprise-grade architecture with an enduring goal of mastering Ruby and Rails.
