With your support I hope to re-start my currently mostly dormant OSS contributions.

I've spend the last years as a consultant writing lots of private tools I cannot easily opensourcee on the spot. Instead I want/have-to re-implement them.

My goal is to be able to publish new implementations of these tools and document them. Your contribution will allow me to go down this path.

I plan to opensource after (re-)implementation:

• An SQL testing system for postgresql that is based on the idea of golden tests, begun in https://github.com/mbj/pgt it still misses more docs.
• PostgreSQL plugin exposing the postgresql Parser in a JSON AST (S-Expressions and or structured) with schema inference. This would lead to dramatically improved postgresql tooling.
• Generated stripe client for Haskell.
• Generic OpenAPI based code generator for Haskell.
• OpenAPI tooling (parts exist already in https://github.com/mbj/openapi).

Also more widely used ruby gems I contribute or co-maintain need some polishing, these include

• https://github.com/mbj/unparser - support Ruby - 2.7 syntax generation
• https://github.com/mbj/anima - get to 1.0 release
• https://github.com/mbj/concord - get to 1.0 release
• https://github.com/dkubb/memoizer - change concurrency aware memoization backend to be more performant.

Most of the libraries shown here https://rubygems.org/profiles/mbjs need some love.

Also every extra time the sponsoring program gives me will help me to improve https://github.com/mbj/mutant which is free to use for opensource projects. Plus I'd be able to expand mutant into other languages, keeping its use free to opensource projects.
