How to assess the technical quality of a developer before hiring
See how to assess the technical quality of a developer even without a programming background, with practical signals to watch for.
One of the biggest challenges for non-technical people is: how do I know whether a developer is genuinely good, if I do not understand code? The good news is that there are practical signals, requiring no deep technical knowledge, to assess the quality of a professional before hiring.
1. Ask them to explain technical decisions in plain language
An experienced developer can explain why they chose a given technology or approach in a way anyone can follow, connecting it to business reasoning. If the answer is only technical jargon with no link to the problem you want to solve, that is a warning sign.
2. Review the portfolio with specific questions
Instead of just looking at screenshots, ask: "what problem did this project solve?", "what would you do differently today?", "what was the biggest technical challenge?". The answers reveal maturity and the ability to reflect critically on their own work.
3. Ask about testing and security
Even without understanding the technical details, you can ask: "how do you make sure the system will not break when I request a change in the future?" and "how will you protect the data of my customers?". Vague or overly generic answers are a red flag.
4. Watch communication, not just technical skill
A good developer translates technical problems into business decisions, is transparent about risks and deadlines, and does not promise "sure, it can all be done fast" without understanding the full context of what you need.
5. Ask for real references
Talk to previous clients about deadlines met, delivery quality and how the professional handled the unexpected. That usually reveals more than any isolated technical test.
Warning signs
- Promises of unrealistic deadlines without understanding the full scope;
- Difficulty explaining technical decisions without excessive jargon;
- Resistance to formalizing scope, deadlines and deliverables in a contract;
- Lack of concrete examples of complete previous projects.
Conclusion
You do not need to know how to code to identify a good developer — you need to know which questions to ask and to pay attention to how they are answered. Clarity, transparency and the ability to connect technology to business results are more reliable signals than any isolated technical test.
