Paying for Bolt, I've finished my first app. While it's pending in the app store, I'm trying to build a second one, but even after doing the full implementation and design with Gemini and putting it into a prompt, I keep getting errors. It seems like even if the design is all…

After struggling with a persistent bug using Claude, I switched to Gemini and it fixed the error right away. It's a great reminder that different AI models have unique problem-solving approaches. If you're stuck, try another AI! #Programming #AI #DevLife
It's a small detail, but for specific coding rules in #Nextjs like "use the <Link> component instead of an <a> tag" it feels like a good idea to have a dedicated sub-agent that performs the final check. #claudecode
Hit some new challenges with my main project, so naturally, I built and launched a new app in 3 days. The combo of bolt.new for the UI and Claude for the final polish is a game-changer. The development speed is incredible! #solopreneur #claudecode
September in Japan... busiest time of the year for many companies due to the fiscal year-end. Budgets get bigger, workload explodes, and my dev projects are barely moving forward. Squeezing in even 30 minutes a day is a struggle. How does everyone else manage development and…

Hack for getting better results from Claude Code... Don't jump straight to implementation. - Have it focus only on the design and generate a design doc. - Use that doc for the implementation phase. - Keeps the context clean and the code much better. Wrote about it here:…
Wake up Claude Code!!
If you only chase short-term "Time Performance," you risk damaging your overall "Life Performance." Instead of efficiency by the hour, think about how to maximize yourself over an 80-year span. Just changing your perspective will change your actions today. #LifeDesign…
The old-school "just have grit" mentality was definitely excessive. But it's also true that those "unreasonable" efforts are what made me who I am today. Sometimes I think the most personal growth is found in the most "inefficient" of times. #WorkEthic #PersonalGrowth

Code without marketing = dead project. Marketing without code = scam. Do both = startup. Do you agree or not ?? 🤔
Taming Claude Code’s Sub-agents: A Guide to Making AI Collaboration Actually Work medium.com/@jakk_hack_jp/…
On the topic of AI and technical debt. While there are current limitations, I see them as temporary. The long-term challenge seems to be less about code generation and more about code management.
Time in your youth is an asset you can never get back. There's a world of difference between coasting in your 20s and getting serious at 40, versus working hard in your 20s and having options at 40. The idea that "I'll get serious later" just doesn't work. #SelfImprovement…
It's okay to have a period in your 20s where you just work hard without worrying if something has "bad Taipa." That struggle is what leads to freedom with your time and money in your 40s. Front-loading the effort gives you a much higher life performance overall. #CareerAdvice…
