Top SchoolKallin Nagelberg is a seasoned software engineer and technical leader with over a decade of hands-on experience modernizing complex platforms and building high-performing teams. He has led engineering growth at Financeit from 15 to 40 engineers, architected critical migrations and payment systems, and drove developer experience improvements that enabled frequent, auditable releases. A pragmatic full-stack developer, Kallin pairs deep Ruby on Rails and platform expertise with data tooling (Python/Pandas, Elasticsearch) and a growing focus on AI/LLM applications—recently winning a LangChain hackathon for a merchant assistant prototype. He combines people-first management (career ladders, engineering managers, onboarding) with a track record of technical execution on large migrations and acquisitions, and now brings that blend to his role at Wiza in Old Toronto.
