Summary
👤
Senior🎓
Top SchoolRobert Rossmann is a Node.js backend engineer with 13 years of experience building scalable server-side services and modern web applications from Prague-region STRV to enterprise projects. He favors simplicity and elegant design, and routinely engages with stakeholders to understand business needs before writing a line of code. An active open-source contributor, he has improved authentication and JWT handling in Google's official Node.js API client and fixed core issues in the Trails.js framework, reflecting attention to security and cross-platform behavior. His background spans service architecture, automation and operations (Ansible, Google Apps integrations) through hands-on roles in development and support, giving him practical systems and deployment savvy. Outside work he contributes to OSS, reads widely (Sci‑Fi/Fantasy), plays guitar and bodhrán, and brings a curious, culturally minded approach to engineering — and yes, he really hates coffee and early mornings.
