About this gig

We build custom web applications and internal business software for companies whose needs have outgrown off-the-shelf tools client/asset management systems, internal dashboards, service platforms, and workflow automation.

This isn't template work: every application is architected around your actual process, with clean, scalable, well-documented code and a deployment process that's tested and secure from day one. Our own product, OpsCore a unified IT operations platform (CRM/CMDB/DCIM/helpdesk in one) was built entirely in-house, so we design and ship complex, real-world software, not just prototypes.

What you get:

  • Requirements & architecture planning before a line of code is written
  • Custom-built, scalable, maintainable code not a no-code wrapper
  • Secure authentication, role-based access, and clean data modeling
  • API integrations with the tools you already use
  • Deployment, testing, and post-launch support

Why work with us: We come from a systems and infrastructure background as much as a development one so security, performance, and reliability aren't an afterthought, they're built in from the start.

Hi, I'm Stefan, owner and lead developer at Zerobug Development. I build and maintain web apps, backed by hands-on system administration — from physical servers through virtualization to networking and DNS, up to the software layer. Skills: HTML, CSS, JS, Angular, REST APIs, C#, MS SQL, VMware/Hyper-V, F5 BIG-IP, Check Point, Fortinet, Windows/Linux admin, DNS. Most devs stop at the code — I understand the full stack behind your app, meaning fewer surprises with deployment and uptime. I work solo, stay personally involved, and stick to agreements and deadlines.
