I'm considering selling my MVP cloud factory architecture, which has virtually zero monthly operating costs. Anyone interested?

7/ I used to keep this opinion to myself, but now that AI has reached semi-autonomous development, it's undeniable. If you’re still obsessing over "DRY" and forcing abstractions, you’re just confusing the AI and wasting your boss’s money. 💸

"Shared code is garbage."

[Ruisheng Xu @throuz1]

6/ By keeping code local and repetitive instead of shared and abstract, you maintain Super Elasticity. You can pivot any part of the logic without breaking the whole system. In 2026, this trade-off is a massive win.

[Ruisheng Xu @throuz1]

5/ Then comes the classic: "But then I have to change it in multiple places!" Please. It’s not hundreds of places, and more importantly—YOU aren’t changing it; the AI is.

[Ruisheng Xu @throuz1]

4/ People argue: "But I need that package's functionality!" In the era of AI, do you really? 99% of those "essential" features can be generated as clean, local code. You don't need the bloat of a dependency just to avoid writing a few lines.

[Ruisheng Xu @throuz1]

3/ Even worse? People doing "abstractions of abstractions." It’s a total disaster. The most common sin is wrapping a third-party package in another layer of encapsulation. I still don't get why everyone does this. It's overhead for the sake of overhead.

[Ruisheng Xu @throuz1]

2/ Every piece of shared code is a point of infinite entropy. The moment you abstract logic to "save time," you’ve created a trap. When one specific use case needs a tiny change, the complexity of your shared abstraction skyrockets because you start hacking in "exceptions."

[Ruisheng Xu @throuz1]

1/ I’ve held this "unconventional" view for years, and the rise of AI-driven development has only confirmed it: Shared code is a ticking time bomb. 💣

Got gout <30. Reading menus sucks.

Built GoutScan: Snap a menu, see gout risks.

I wasted a week over-optimizing (10+ models/OCR). Learned the hard way: Launch for validation, don't hide for perfection.

It's slow (30s), but it works.

Is $5 a fair price for a developer's soul? I’d say it’s a steal. 🤷‍♂️

I launched a 72-hour MVP Risk Memo.
No code. Decision vetoes only.

Built for founders before irreversible decisions.

[Ruisheng Xu @throuz1]

5/5
My 5th (eHRM HR system) finally paid off — client work delivered in 8 weeks.
Now I ship for founders: Web3, trading tools, SaaS, AI agents. 6–12 weeks to MVP.
DM “MVP” for availability & pricing. No BS, just results.

1/5
I killed 4 products in 18 months so you don’t have to.
Quick thread: the most expensive lessons from my solo builds.

1. Binance RSI Bot
→ Backtested 10k+ strategies in minutes
→ Looked amazing on paper
→ Lost money live
Lesson: Perfect backtest ≠ real profit

[Ruisheng Xu @throuz1]

4/5
4. Reflink (Solana on-chain affiliate)
→ Auto payouts via smart contracts
→ Global hackathon submission
→ Crashed on "no refunds" blockchain limit
Lesson: Cool tech can't fix bad business rules
Rust was fun, but flexibility wins.
