Systems and hosting
Deployment, hosting, server management, uptime concerns, and the small operational details that keep services stable.
Engineering secure, stable systems.
I build and operate technical systems with a focus on clean deployment, strong troubleshooting, and security controls that hold up under real use.
- Ops System administration, hosting, automation, and deployment work.
- Security Testing, hardening, and review with a practical operator perspective.
- Build Custom software and tools built to solve specific problems cleanly.

What Sets Me Apart
Work shaped around infrastructure, security, and software. The focus is simple: make systems easier to operate, safer to expose, and more useful to the people depending on them.
Security testing
Application and infrastructure review with an emphasis on issues that matter in practice, not just checklist output.
Custom development
Web, tooling, and niche software work when the answer is not another off-the-shelf service.
Security-minded
I run my own infrastructure with actual hardening. Not just buzzwords - I know how to lock things down properly.
Real projects
Built CryptX, lwIP-CE, Expanse, and various client projects. Mostly networking and security work.
Certifications
- Cybersecurity Analyst
Application Security Testing
Starts at $2,500
For teams that want real review rather than vague reassurance, the security testing package combines source analysis, endpoint testing, remediation guidance, and retesting.
- Static analysis for up to 50,000 lines of code
- Dynamic testing for up to 25 endpoints
- Optional pentest against isolated staging deployment
- Post-remediation retest included
Discord Bot Security Testing
Starts at $249
Designed for Discord bot projects that need a focused security pass before shipping. This review starts with static testing, layers in manual analysis, and ends with a written report you can actually act on.
- One Discord bot codebase up to 10,000 lines
- Static testing plus manual review
- Dynamic testing and pentesting quoted separately
- Written report with findings, severity, and remediation guidance
