I dabble in macOS development as a hobby and specialize in making small utilities, productivity apps, and even simple games. Every program listed here is (reasonably) well-crafted and updated. Several of my apps have been favorably reviewed by sites such as LifeHacker, iFun, and Spider-mac.
All of my apps are signed and notarized per Apple's best practices. You can also check VirusTotal, which shows that my website is not flagged as malicious.
