Things They Didn’t Teach You About Software Development

In this reflective essay the author, a senior architect, shares practical insights that are rarely covered in formal education but are essential for everyday software engineering work.

Most developers do not start projects from a clean slate; they inherit massive codebases and spend the majority of their time understanding, fixing, and extending existing code rather than writing new features from scratch.

Domain knowledge is emphasized as more valuable than pure coding ability. Understanding how a banking app processes transactions, how a restaurant’s ordering system manages inventory, or how logistics software handles shipments enables engineers to contribute meaningfully and increases their marketability.

The article highlights the chronic neglect of documentation in many teams. Good documentation and clean, maintainable code save countless hours, yet these skills are typically learned only through experience, not taught in university curricula.

It argues that the primary goal of a software engineer is to deliver business value, not to write elegant code for its own sake. Code is merely a tool to create value; the focus should be on solving real problems efficiently.

Dealing with incompetent colleagues, unclear requirements, and constant uncertainty is portrayed as an inevitable part of the job. Strategies such as seeking additional resources, delegating tasks, implementing fallback mechanisms, and maintaining professional communication are suggested.

The author stresses the importance of assuming that everything can fail—whether it’s code, third‑party libraries, operating systems, or hardware—and building systems with resilience in mind.

Finally, the piece concludes that software engineering is a demanding career with long hours, frequent meetings, and limited work‑life balance, but it can be rewarding if one stays focused on continuous learning, documentation, and delivering value while remembering to enjoy the work.
