Hello! 👋
I'm a full-time open source developer.
My open source projects...
- make the Web safer and more private.
- make developer lives easier.
- PapaParse is a JavaScript library that parses CSV files
- JSON-to-Go converts JSON to Go structs
- curl-to-go converts curl commands to Go code
- Archiver is a Go library for working with archive formats
- libdns is a set of universal DNS record manipulation APIs
- preserve personal and family history.
- Timelinize stores all your digital life onto a single timeline, stored locally
- are often used in humanitarian and non-profit efforts.
- PEPFAR uses Caddy to collect medical data in the field
- The United Nations,Wikimedia, and several other public agencies use Papa Parse to process data
My primary work is theCaddy web server. Caddy has:
- 📄 >20 million TLS certificates under management
- ⏬ >50 million downloads
- 🐳 >500 million Docker pulls
- 🔐 >1 trillion TLS connections secured
- 📈>10 TRILLION
‼️ HTTPS requests served
That's a lot of public good for a free project maintained by ~1 developer!Thankfully, Caddy has over 300 contributors. But coordinating that effort takes a lot of time and energy, so I now accept sponsorships to help fund ongoing maintenance of my projects.
Your sponsorships make a difference because although open source work can be satisfying, it is often a drain on mental, emotional, and physical energy.In addition to making full-time development possible, sponsors provide much-needed relief, leading to happier, healthier, less-stressed developers.
My goals for my projects are:
- Make a lasting, positive impact
- Foster a sense of community and goodwill
- Improve your quality of life
Some sponsor tiers get discounted professional services, which include:
- Development
- Consulting
- Training
- Presenting
