Summary
🤩
Rockstar🎓
Top SchoolMatthew Walls is a Senior Software Engineer with 11 years’ experience building backend-first, production-grade services for regulated domains like AML and KYC at Arachnys. Comfortable full-stack but biased toward Scala, Python, and Go, he focuses on platform health, reliability, and scalable service design. His background includes tooling and cloud CI/platform work at The Guardian, where he helped democratize big-data access and built custom testing infrastructure for high-traffic editorial systems. Earlier roles in aviation software emphasised correctness, automated defect analysis, and operational interfaces, giving him practical expertise in safety-critical and enterprise contexts. Based in Colchester, he combines pragmatic engineering with a penchant for infrastructure that enables teams to move fast without sacrificing observability or control. Colleagues value him for turning complex requirements into robust, auditable systems and for preferring well-crafted backend solutions over flashy surface-level fixes.
