Let me be honest with you
I'm an engineer with over 11 years of experience. I've shipped reservation systems, PWAs, FiveM game servers, and electronic health record apps. I design architecture, define data flows, and make product decisions every day.
But I don't write the code myself. My AI team does.
This isn't a confession. It's a workflow — and I think it's the future of solo engineering.
Meet the team
My setup is simple. I use Claude Opus for everything, in two modes:
- 🧠 Me — product design, system architecture, UX decisions
- 📝 Claude Opus (chat) — turns my rough ideas into detailed spec docs and implementation instructions
- 💻 Claude Code (Opus) — reads the spec and actually builds it, file by file
- 🔁 Me again — review, test, iterate
One model. Two roles. Zero context switching between different AI tools.
Why "teammate" — not "tool"
Most developers talk about AI like it's a fancy autocomplete. I don't see it that way.
I gave my AI a name. I treat its outputs like a colleague's pull request — I review them, push back when something's wrong, and give feedback. When the spec isn't right, I don't just re-prompt. I argue with it.
My motto is: "AI to tomo ni" — working alongside AI, not just using it.
That mindset shift changes everything. You stop asking "did it do what I said?" and start asking "is this actually the right solution?" That's where quality comes from.
What changed when I switched to this model
I'm a day-job engineer running a freelance side business. Without AI, I'd be stuck — I can design systems in my head, but I'd never ship fast enough to compete.
Now I can take on projects solo that would normally require a team. Not because AI replaced me — but because it handles the part I was never good at, so I can focus on the part I am.
The honest trade-offs
This workflow isn't perfect. Claude Code still needs clear, structured specs — vague instructions produce vague code. My job is to think precisely so the AI can execute precisely. Garbage in, garbage out still applies.
But the leverage is real. And if you're a designer, PM, or systems thinker who's been told "you need to learn to code" — maybe you don't. Maybe you just need the right team.
I'm Taku, a freelance full-stack engineer based in Japan. I build web apps, PWAs, and game server scripts — mostly with an AI co-pilot. If this resonates, follow along. More posts coming on FiveM dev and PHP system architecture.
