Web developer & Owner
Zerobug Development • Autônomo
Jan 2026 - Present • 8 mos
Hi, I'm Stefan — owner and lead developer at Zerobug Development. I build and maintain web applications and websites, backed by a rare combination: hands-on system administration experience that goes from physical server hardware, through virtualization and network configuration, all the way up to the software layer — which is where I spend most of my time today as a web/software developer. What I bring: - Web development: HTML, CSS, JavaScript, Angular, REST APIs, C#, MS SQL - Infrastructure background: physical server rooms, virtualized environments (VMware/vSphere, Hyper-V), network configuration (F5 BIG-IP, Check Point, Fortinet), Windows Server & Linux administration, DNS/domain management - End-to-end project management, from planning to deployment and post-launch support - I work solo and stay personally involved in every project, bringing in extra help only when a project's scope calls for it Why this matters for you: most web developers stop at the code. I understand the full stack your application runs on — server, network, and DNS — which means fewer surprises with deployment, uptime, and performance down the line. I stick to agreements and deadlines, so working with me is straightforward.
