Top SchoolMichal Mikolajczyk is a Senior Full-stack Software Engineer with 12 years’ experience delivering remote-first projects for international clients, currently at Toptal where he’s led multiple teams and acted as tech lead on complex front-end and API initiatives. He combines hands-on full-stack development (React, AngularJS, Node.js, Go) with architecture, DevOps (AWS, Heroku, Docker/Terraform experience) and SRE practices, enabling reliable production releases. As a founder and CEO of VIKING GARAGE and earlier Trewebs, he bootstrapped startups, shipped fast MVPs and led open-source efforts (including a Toptal Open-Source Grant project).

Outside core engineering, Michal grew the Toptal Warsaw community from a handful to 100+ members, organized conferences and evangelizes remote work—an indicator of his people-first leadership. His background in psychology and multiple edX software engineering certificates underpin a rare mix of user-centered thinking and technical rigor.
