Your AI Partnership

You Own Architecture, AI Owns Implementation

Most developers use AI in one of three broken ways. If any of these sound like you, don't worry — everyone starts here.

The three models that don't work

The Autocomplete Trap

You write most of the code yourself and let AI finish your sentences. It suggests variable names, completes function bodies, fills in imports. You're getting maybe 20-30% more throughput. Your IDE just got a bit smarter, that's all.

The Stack Overflow Trap

You paste problems into ChatGPT and copy-paste solutions back. Faster than searching, sure, but the answers are generic. They don't know about your database schema, your naming conventions, or the library versions you're actually using. You spend two hours integrating a solution that didn't account for your project's specifics.

The Unguided Generator Trap

You tell AI to build whole features without constraints. It picks its own architecture, invents patterns, and creates code that technically works but doesn't fit anything else in your codebase. Now you've got six different patterns for the same thing. Congratulations — you've automated technical debt.

The model that works

Give AI your decisions. Then get out of its way.

The five-minute investment that saves five hours

Here's what the partnership looks like in practice. You write a Pydantic schema — 5-10 minutes of actual thinking about your domain:

class TaskCreate(BaseModel):
    project_id: UUID
    assignee_id: UUID
    due_date: datetime
    story_points: int = Field(default=3, ge=1, le=21)
    priority: TaskPriority
    description: str = Field(..., min_length=3, max_length=500)

From that single schema, AI generates the service layer (30 seconds), route handlers (30 seconds), database migration (20 seconds), test suite (45 seconds), and TypeScript types (20 seconds). Five minutes of your thinking, five minutes of AI execution, and you've got a complete feature that follows every convention in your project.

The compression timeline

Four failure modes to watch for

  1. Insufficient context — AI generates wrong patterns? Your docs need updating, not your prompts
  2. Blind trust — Never merge code you haven't reviewed. AI writes confident nonsense just as fluently as confident correctness
  3. Micromanaging — If you're dictating variable names to AI, you're doing it wrong. Focus on what and why
  4. No quality gates — Type checking, linting, and tests catch AI mistakes automatically. Without them, mistakes ship to production
