My Engineering Principles: Own the Whole Problem
TL;DR
I build by owning the whole problem — design, code, ship, operate — not just implementing specs. Here are the principles that shape how I work.
I build by owning the whole problem — design, code, ship, operate — not just implementing specs handed to me. These principles shape how I work across every product at Shahriar Labs.
1. Own the whole problem
If you ship a feature but cannot debug it in production, you did not own it. If you can debug it but cannot explain why it exists, you do not own it either. Ownership stops at the user's experience, not the merge commit.
2. Cheap iterations beat clever design
A working ugly version this week beats an elegant version next quarter. Then refactor based on actual usage, not imagined usage.
3. The interface is the product
Most engineers obsess about implementation. Users only see the interface. Spend an hour fixing the error message; the user won't see your beautiful retry logic.
4. Buy the boring, build the differentiated
Auth, payments, dashboards — buy. The thing your product is uniquely good at — build.
5. Reuse > reinvent
A skills layer (My AI Agent Skills Stack) means I don't write the same setup three times. A microservices template (Microservices as One Engineer) means new services start fast.
6. The right abstraction at the right time
The Rule of Three: write it three times before abstracting. Premature abstraction is technical debt with extra steps.
7. Observability is non-optional
Logs, metrics, traces from day one. Adding observability later is 5× the cost of building it in.
8. Decisions over taste
When teams disagree, the question is rarely "what is best." It is "what decision do we make and live with." Make the call; document the reason; revisit when the reason changes.
9. Your time has compound returns
The hours you spend on tools that make every future hour faster are the most valuable. AI agent skills, deployment scripts, observability — those compound.
10. The user does not care
Not about your stack. Not about your code review process. Not about your favorite framework. Care about the user; the rest follows.
How this plays out
The Solo Founder Stack — these principles, applied as a shipping discipline.
How I Use Claude Code to Ship Faster — the workflow that comes from "your time has compound returns."
FAQ
Q: Did you always believe these? A: No. Most are scar tissue from a wrong call I made once.
Q: How do you balance "own the whole problem" with delegation? A: Delegate execution; own the outcome. The bug in the deployed feature is yours either way.
