Technical Consultant at Bear Metal
Finland
Summary
🤩
RockstarMika Tuupola is a pragmatic technical consultant with 19 years of experience building and hardening web systems across PHP, Python, C, JavaScript and Go. He specializes in reliable, maintainable infrastructure—regularly wrestling with Terraform and Kubernetes—and prefers proven, boring stacks that just work. Mika has led technology teams and consultancy engagements, shipping backend middleware like slim-jwt-auth and contributing quality-focused fixes to the Slim framework. On the front end he’s improved usability and performance in widely used libraries (jQuery plugins and a vanilla JS lazyloader), showing attention to backward compatibility and progressive enhancement. Based in Finland, he blends hands-on coding with practical architecture and testing discipline, often favoring small, well-tested changes over flashy rewrites. Quiet but effective, he brings decades of production experience and a no-nonsense approach to solving thorny engineering problems.
