Hello 👋

I'm Dan, the creator of Performance-oriented Data Structures for Kotlin. I left my day job in 2022 to spend time outdoors and be energized to build things that will inspire others to follow their passion. I've trained and mentored hundreds of developers as a senior developer and hope to make an even larger impact through open-source contributions in the Kotlin ecosystem.

My current focus is on adding capabilities to Immutable Arrays to provide a safer and more efficient alternative to read-only lists. After that, I have several cool open-source ideas. Although I haven't decided yet, some working prototypes include:

• Add more performance-oriented data structures to pods4k
  • I have a specialized Set data structure that can perform most operations, like set intersection, in sub-linear time
• A declarative assertion library
  • This can be turned off for production builds so that assertions are stripped away at compile time to have no performance impact in production.
• A full-blown computer algebra system
  • Step-by-step simplifications, derivatives, integrals, etc.
  • Kind of like a baby brother to Sympy but with an architecture that allows me to be 100X more productive
• A fuzz-testing library that automatically narrows in on the root cause of the defect.
  • This made a large impact on my computer algebra system finding hundreds of scenarios I hadn't considered.
  • I added automated narrowing-in on the root cause as that was often difficult to track down and this easily increased my productivity by 10X.
• etc.

By sponsoring my work, you're investing in the future of Kotlin development. Your support enables me to:

• Dedicate more time creating high-quality libraries for Kotlin
