I'm a senior software engineer and tech lead with 11 years of experience building software for large companies.
After years of working with Jira and Confluence, I started building small, focused apps for the problems I kept seeing in everyday work.
I design, build, and support every Misheno app myself.
Email me with product questions or feedback. I handle support for all Misheno apps myself.
