I have been working as a Support Engineer for three years, and while I’m comfortable with troubleshooting and reading logs, I want to move into a core Software Development role. I’m finding it difficult to prove my coding abilities to recruiters who only see my "support" background. What are the most effective ways to leverage my current experience, what specific gaps in my knowledge should I prioritize, and how can I build a portfolio that demonstrates I can build features, not just fix them?

The transition from support to development is actually a very natural path because you already possess one of a developer's most valuable skills: debugging. To make the switch, you need to shift from "problem-solving" to "solution-building." Start by automating your current support tasks using Python or Bash scripts and host these on GitHub. When applying for roles, highlight your deep understanding of the user experience and your ability to diagnose complex system failures—these are unique strengths that many "pure" developers lack. In professional Software Development, the ability to read and understand existing codebases is half the battle, and your support background gives you a head start there.
Should I focus on contributing to Open Source projects to gain "real-world" experience, or is it better to build a few high-quality personal projects from scratch to show I understand the full application lifecycle?
Don't overlook the importance of Data Structures and Algorithms. Even if you don't use them daily, they are the "gatekeepers" of the interview process for many development roles.
I agree with Sarah; technical interviews are a different beast than support troubleshooting. Dedicate time to LeetCode or similar platforms to ensure you can pass the initial coding screens that often trip up self-taught or transitioning engineers!
Marcus, both are great, but for a Support Engineer, I highly recommend a "Bug Fix" approach. Find an open-source tool you use at work, find a reported issue, and submit a Pull Request. This proves you can work within a professional Software Development workflow (Git, CI/CD, Code Reviews). Recruiters love to see that you understand how to navigate a large, unfamiliar codebase. It bridges the gap between "fixing" and "developing" perfectly. It shows you aren't just a hobbyist, but someone who understands the rigor of enterprise-level production code.
