What I’m up to…

Last updated Sep 8th 2025.

My story in 7 bullet points…

  1. Started my career as a corrective exercise coach for people with severe back pain.
  2. After 7 years as a physical therapist, I needed a change. I dabbled on the design side of things for a year or two, and UX (whatever that means), but I eventually gravitated towards the tech.
  3. At 27, I pulled the trigger and I taught myself how to code. Worked as a freelance software engineer for about 5 years.
  4. Realised that I enjoyed the product side of software development much more than engineering. I gradually began to focus on helping companies improve their user retention metrics. Eventually, I transitioned to becoming a full-time consultant.
  5. At some point along the way, I began using a tool called Chirr App to write Twitter threads. Reached out to the founder, Sasha Koss, and shared my appreciation. We became friends. A year later, I joined the project as a co-founder.
  6. Sasha and I began working on Chirr App full-time. A tiny bootstrapped team of 3, and we worked hard to build a tool that helps businesses share what they do on Twitter. Then Elon Musk bought Twitter at the end of 2022, and it almost destroyed the business.
  7. We switched to building a prompt chaining tool called DaisyChain. We spent a year working on it, but it didn’t go anywhere, so we decided to start work on a new project called Mind Control. This time, it was a content management system for prompts.

Things I’ve Learned

Done my best to distil the practical lessons from my projects into a collection of useful guides…
