Available for Freelance Work
I ship apps, automate homes, and deploy AI infrastructure.
I'm Charles — a systems engineer with a production homelab running 174TB of storage and 45 Home Assistant automations, hands-on experience with local AI deployment, Claude Code multi-worker orchestration, and React Native mobile development.
Everything I offer is battle-tested on my own infrastructure. I don't just know how to build these systems — I run them 24/7.

Frequently Asked Questions
Do you work remotely?
Yes, 100% of my work is done remotely via secure screen sharing and remote access. I'm based in the US (Eastern Time) and work with clients worldwide. Most projects kick off over a video call.
How do I get a quote for my project?
Email me at [email protected] with a description of what you're trying to accomplish. I'll respond within 24 hours with questions or a rough estimate. For app development, I typically provide a detailed proposal within 48 hours.
What's included in the handoff?
Every project includes full documentation, configuration files, and a walkthrough session. You own everything — no proprietary lock-in or recurring fees required to keep things running. I want you to be self-sufficient.
How do I pay?
I accept PayPal, Venmo, and bank transfer (ACH/Wire). For projects over $1,000, I typically split into 50% upfront and 50% on completion. Hourly work is billed weekly.
What if something breaks after handoff?
All projects include 30 days of follow-up support for configuration issues at no extra charge. After that, hourly support is available, or consider a retainer for ongoing maintenance.
Can you publish my app to the App Store (iOS)?
Yes! While my portfolio is primarily Android (Google Play), React Native apps can be built for both platforms. iOS publishing requires an Apple Developer account ($99/year) and has additional review requirements.
