Summary
👤
Senior🎓
Top SchoolCraig Crawford is a polyglot software engineer and white-hat hacker based in Glasgow with 15 years of experience blending systems administration, customer-facing support, and secure software development. He’s fluent in languages from Python, C#, and Go to TypeScript and PowerShell, and has practical OS expertise across Linux and Windows. Craig has worked in support and engineering roles at Aiven and Flexera, contributed backend fixes to the popular MyBB open-source forum (improving email handling and privacy), and runs his own cryptocurrency trading business since 2017. He combines a tinkerer’s curiosity—rooted in early BIOS and Linux experiments and hardware modding—with a strong track record of finding and remediating injection, XSS, and auth vulnerabilities. Comfortable troubleshooting sensitive customer issues, he enjoys teaching others and seeing his technical work quietly deliver value. An unexpected detail: his hobbyist mod ideas made it into a commercial game and he once operated a Cardano staking pool, reflecting both creative and operational interests in decentralised tech.
