Summary
🤩
Rockstar🎓
Top SchoolErvin Hegedüs is a seasoned Software System Engineer based in Budapest with 13 years of experience building and hardening system-level software and networked services. He combines strong low-level skills in C, TCP/IP and systems administration with high-productivity scripting in Python, SQL and PHP to deliver reliable, testable solutions. At DigitalWave and as a long-term OWASP ModSecurity CRS contributor he has focused on security, automation and correctness—authoring tooling that improves rule testing and fixing subtle parsing and cross-platform bugs in the ModSecurity WAF. His work shows a pragmatic attention to test-data analysis and edge-case handling, such as longest-test-case discovery and big-endian 64-bit inet address support. A BSc in Computer Science from Eötvös Loránd University underpins his engineering approach, and his GitHub bio’s wink—“Whitespace makes me happy”—hints at a preference for clean, readable code and meticulous craftsmanship.
