Something unexpected happened in the hardware market recently. Mac Minis—Apple’s unassuming small desktop computers—started flying off shelves. The cause wasn’t a new chip announcement or a price drop. It was an open-source project called Clawdbot.

Growth as a software engineer isn’t linear. It’s not just about writing more code or learning more frameworks. It’s about developing technical depth, expanding your impact, building judgment, and continuously adapting to an industry that reinvents itself every few years. Here’s how to grow deliberately throughout your career.

When building modern web applications, you need two fundamental capabilities: knowing who your users are (authentication) and controlling what they can do (authorization). OAuth2 and OpenID Connect are the industry standards for these problems, but they’re often confused because OpenID Connect is built on top of OAuth2. Understanding the distinction is essential for implementing security correctly.

Every engineering team has a backlog of tech debt. Outdated dependencies, brittle tests, duplicated logic, poor abstractions, missing documentation. It’s easy to defer this work—features ship, customers are happy, metrics go up. But tech debt compounds. What starts as a small shortcut becomes a systemic drag on velocity. Teams that don’t prioritize tech debt eventually grind to a halt, unable to ship even simple changes without breaking things.

Small teams can coordinate through hallway conversations and Slack messages. Everyone knows what everyone else is working on. Decisions happen organically. This feels fast and nimble—no meetings, no documentation, no bureaucracy. But as teams grow, this breaks down. People step on each other’s toes. Duplicated work emerges. Critical knowledge lives in one person’s head. Onboarding takes months because nothing is written down. What worked for five engineers fails catastrophically at fifty.
