Architecture decisions before you write code
The expensive mistakes rarely happen in the editor. They happen in the week before anyone opens a repo, when someone picks a stack, a data model, or a “temporary” integration that becomes permanent.
You don’t need a 40-page architecture document. You do need a few decisions made on purpose.
Start with the problem, not the toolbox
Before frameworks and cloud providers, answer:
- Who is this for, and what must be true on day one?
- What will change in the next six months and what must stay stable?
- What’s the blast radius if this breaks: annoyed users, lost money, or irreversible on-chain state?
Those answers constrain everything else. A property management workflow and a smart contract release don’t deserve the same architecture.
Decide the hard boundaries early
Most small systems need clarity on four lines:
- Where data lives — one source of truth beats three “sync later” databases
- Where trust lives — auth, permissions, and who can change critical state
- Where money or irreversible actions live — payments, minting, deletes, admin powers
- Where integrations live — third-party APIs fail; plan for that at the edge, not in the core
If those boundaries are fuzzy, the code will invent them for you and is usually done poorly.
Build, buy, or wait
For each major piece, force a choice:
- Build when it’s your differentiation or too core to outsource
- Buy when the problem is solved and your time is better spent elsewhere
- Wait when you’re guessing at requirements you haven’t felt yet
“We’ll build our own auth / billing / workflow engine” is a common way small teams slow themselves down. So is bolting on five SaaS tools with no owner for how they fit together.
Choose for operability, not novelty
A stack your team can deploy, debug, and hire for beats a fashionable one nobody can run at 2 a.m. Prefer:
- Boring deployments you can roll back
- Observability you can afford to maintain
- Schemas and APIs that can evolve without a rewrite
On-chain work raises the bar further: upgrade paths, access control, and test strategy are architecture, not polish.
Write the decisions down — briefly
A one-page note is enough:
- What we chose
- What we rejected
- What would make us revisit this
That’s how future you (or the next engineer) avoids re-litigating every week.
Technical planning isn’t delay. It’s how you keep the first real sprint pointed at the product instead of cleaning up an accidental system.
