Summary
👤
Senior🎓
Top SchoolTobias Haar is a Principal Software Engineer based in Newcastle upon Tyne with 14–15 years of experience building and leading engineering teams across fintech, SaaS, and big-data platforms. He blends hands-on architecture and platform work—migrating monoliths to services, replatforming to containerised AWS environments, and slashing CI/CD and job runtimes—with people leadership from indie IC coaching to managing multi-country teams. His background spans Ruby on Rails, React, Go, AWS/Terraform and large-scale data pipelines, and he has repeatedly driven projects that improve developer velocity and operational resilience. Notable wins include extracting services from monoliths, migrating terabytes of attachments off shared file systems, and operationalising managed infrastructure to accelerate delivery. Tobias is customer-obsessed and continuously raises engineering standards through tooling, security automation, and OKR-driven architecture forums. He pairs a pragmatic delivery focus with a track record of mentoring engineers to scale both teams and systems.
