Engineer, entrepeneur, and writer
I'm Bill, a software developer and writer living in San Francisco. I'm currently focused on trying to grow an app to $10k MRR and writing about my journey. Previously, I was a software engineer for about 13 years at companies such as Google, Pinterest, and many small startups. Besides my Substack, I also have some blog posts on the articles page and on my old Medium.
You can email me waprin@gmail.com , connect with me on Twitter, or LinkedIn.
The rest of this page gives an overview of current and past projects and some more personal information about me.
Live Poker Theory
My biggest current focus is a poker training product called Live Poker Theory. Live Poker Theory helps bridge the gap between complex game-theory solver software and applying those theoretical concepts to live poker games. It primarily aims to do this by creating flashcards based on the solver outputs. It's inspired by research-based studying tools like Anki which aim to optimize your studying efficacy, and language learning apps like Duolingo which gamify the learning experience.
Inactive Projects
Interstitch
I'm also very interested in using software to improve productivity. Interstitch makes it easy to implement a technique called "interstitial journaling ". Interstitial journaling was coined by the Medium CEO Tony Stubblebine and popularized by the wellness and productivity blogger Anne-Laure Le Cunff of Ness Labs. It's a technique where you write notes on your work as you go about it and collect timestamps. Interstitch organizes those notes by color-coded project and tracks the timestamps as you go so you can set goals on how many hours of "deep work " you do per project.
