"Hello, World!"
It's the first line of code we learn to write. It is clean, predictable, and runs perfectly in isolation. For a long time, I thought the job of a developer was simply writing bigger, more complex versions of that perfect script. You get a ticket, you lock yourself away, you write the code, you ensure it passes both your tests and QA's, and you move on.
But code is only a fraction of the puzzle…
Seeing the Whole Puzzle
In my early years, I worked in isolation. My world was the size of my current task. If my function worked and passed the tests, my job felt "Done." I was ready—probably too eager—to get assigned a new one and repeat the loop.
The shift to engineering happens when you zoom out and start asking questions:
- Why are we doing this?
- What specific problem are we solving with this implementation?
- What happens to the business if we ship it, delay it, or simply drop it?
- Is it even necessary as-is, or does it require more grooming with stakeholders to ensure it matches what our users need?
You stop looking at the individual implementation and start looking at system design. You realize your code is a single piece of a large, living ecosystem. You begin architecting for scalability, performance, and observability. This is where best practices come into play, but more importantly, understanding why you use them—and what happens if you don't—is key to technical growth.
Owning "Done" (and the Fires)
As a developer, "Done" often means "it works on my machine (and staging 😉)." As an engineer, you own the entire lifecycle.
True ownership means redefining the word "Done" to mean safely running in production under a specific set of conditions. And when production catches fire unexpectedly? You do not panic or point fingers. You jump into the trenches, triage the issue, put out the fire, unblock users, and build the guardrails to ensure it never happens again (or so one may hope).
Code is Cheap, Collaboration is Key
And it's getting cheaper and cheaper, one new LLM model release at a time.
That's why we must understand that software is a team sport, yet many of us start our careers trying to score goals alone. The real career growth happens when you open your door to collaboration:
- With Devs & QAs: Breaking down silos to catch edge cases early.
- With POs & Stakeholders: Translating business vision into technical execution.
- Cross-Team: Aligning different departments to prevent friction and ensure success, often before a single line of code is written.
The Differentiator Metric: Unblocking Your Team
The hardest mindset shift to make is usually moving away from individual metrics. Closing your own tickets feels great, but it is a bottleneck if one of your teammates is stuck.
Being an engineer means realizing that your team's velocity matters more than your solo output. It means pausing your own feature to mentor a junior peer, hopping on a pair-programming session, or unblocking a teammate. Success is no longer measured by how much throughput you're achieving with your AI tool of choice, but by how much you elevate the people around you—regardless of how many tokens you've consumed.
What's one moment in your career that changed your definition of "Done"?
