Summary

Rockstar🎓
Top SchoolTom A is a founder and seasoned full-stack engineer with 13 years of experience building scalable, production-grade systems and B2B SaaS used in 80+ countries. He combines deep backend expertise in Go and Node.js with hands-on contributions to notable open-source projects—everything from high-performance image processing (bimg, imaginary) to binary file detection (filetype) and resilient HTTP tooling (toxy). His background spans startups, fintech R&D, and security intelligence, where he architected platforms, led remote teams, and supported Fortune 500 and government clients. Tom is pragmatic about opportunities—focused on running his company—but remains an active maintainer and problem-solver in OSS, often refactoring core libraries and adding practical features like CLI tooling, format support, and test coverage. Based in Estonia, he pairs systems-level thinking with a hacker’s curiosity for AI and clever tooling, describing himself playfully as a "Computers + AI harasser."
