The biggest difficulty was that the programmers I worked with didn’t have experience in Bitcoin or open-source protocol development. Many of Nostr’s protocol interfaces and feature implementations came with serious technical challenges. I spent a lot of time solving problems that looked simple on the surface. Another issue was remote collaboration — everyone inevitably runs into unexpected situations, so development schedules were hard to guarantee. Just as someone was getting familiar with the overall technical architecture, I had to look for a new collaborator. A lot of time was wasted in that process, and it was quite exhausting. But things are much better now. Claude Code has become my full-stack technical mentor, my partner for executing programming tasks, and essentially my CTO, working together with ChatGPT and Gemini to solve hard technical problems. I can push product development forward anytime, anywhere. It honestly feels amazing. Right now, the biggest bottleneck is simply that I don’t have enough time.
