Lead production Linux hosting escalations involving cPanel, web stacks, PHP-FPM, databases, DNS, mail, SSL, and recovery workflows. Coordinate migrations and incident response through evidence gathering, dependency review, staged changes, and clear customer or stakeholder handoffs; build Bash and Python automation for repeatable diagnostic and server-management work.
Career profile
Stephan Loesevitz
Linux Systems / Infrastructure Engineer open to full-time Infrastructure Engineering, Platform Engineering, Linux Systems Engineering, and SRE opportunities.
How to read the work
Cyber Duct Tape is the consulting practice. StePanel is the flagship engineering project.
I maintain the practice while building tools and workflows that make production infrastructure safer to change and easier to recover. The commercial work keeps the problems real; the public repositories show how I reason about them.
I am looking for a team where that incident-response mindset can operate at larger scale, with stronger platform feedback loops and shared ownership.
Cyber Duct Tape is my independent infrastructure practice and portfolio. I am seeking full-time infrastructure, platform, Linux systems, and selected SRE roles where the same production-safety mindset can operate inside a larger engineering team.
Representative impact
Production problems turned into safer systems, tools, and handoffs.
- Built StePanel, a Go-based Linux hosting control plane with migration, backup, durable job, audit, and operator workflow concepts.
- Handled Linux hosting escalations across web, DNS, mail, database, WordPress, SSL, PHP-FPM, cPanel, and recovery issues.
- Converted repeated diagnostic and recovery patterns into public tools including Support-DoKtor, FPM Lens, Fail2ban hardening, and WordPress archive tooling.
- Operated multi-site Bitcoin mining infrastructure with approximately 40 MW of combined power capacity and large ASIC deployments.
- Produced public runbooks for cPanel migrations, DNS outages, PHP-FPM capacity planning, MySQL recovery, backup validation, and WordPress incident response.
Career progression
Hardware and datacenter operations → hosting support → escalations → infrastructure engineering.
Complex hosting troubleshooting, service dependencies, and structured technical handoffs for high-impact support work.
Troubleshot WordPress, DNS, email delivery, SSL, and website issues through phone, chat, and ticket systems while guiding customers through technical solutions.
Managed daily operations across multiple cryptocurrency mining facilities with approximately 40 MW of combined power capacity; maintained large-scale ASIC deployments and trained technicians.
Operational scale
From customer-facing support to fleet-level infrastructure.
Earlier work included multi-site datacenter operations at approximately 40 MW of combined power capacity, large-scale ASIC deployments, and Bash/SSH automation for firmware updates across hundreds of devices.
That background complements the hosting and platform work: I have operated both the customer-impacting service layer and the underlying physical infrastructure.
Credentials and training
Relevant platform, hosting, database, data, project, and systems training.
Role fit
Next step
Review the source, then talk through the operational decisions.
The best starting points are StePanel for platform design, Support-DoKtor for incident tooling, and the infrastructure automation projects for repeatable host operations.
