For over five years, my "bugs" weren't in code. They were in DNA sequencing runs that came back with unreadable peaks, PCR reactions that refused to amplify, and antioxidant assays that gave inconsistent results across replicates.
I have a background in Biotechnology and a Master's in Chemical Biology. I spent years in research labs analyzing experimental data, documenting processes, and trying to figure out why something that worked yesterday suddenly didn't work today.
Now I'm a career changer, studying Systems Analysis and Development and building my first real projects in Python. And the thing that surprised me most about learning to code wasn't the syntax. It was how familiar the process of debugging felt.
The scientific method is a debugging method
In the lab, when an experiment failed, you didn't just try random things until it worked. You had to:
- Isolate the variable that changed
- Form a hypothesis about what went wrong
- Test that hypothesis in the smallest possible way
- Document what you tried, even when it didn't work
That's... exactly what debugging is. When my first FastAPI project threw an error I didn't understand, I caught myself doing the same thing I'd done hundreds of times in a lab: change one thing, re-run, observe, repeat. Don't guess wildly. Narrow it down.
Reproducibility matters more than you think
One of the hardest lessons from research was that a result nobody else can reproduce isn't really a result. If I couldn't explain exactly what I did, in what order, with what parameters, my data was worthless to anyone else, including future me, six months later, trying to remember what I did.
That obsession with documentation carried straight over into version control. Writing clear commit messages, keeping a README that actually explains what a project does and why, structuring code so someone else (or future me) can follow the logic, none of that felt like a "best practice" I had to learn from scratch. It felt like something I already knew was important, just applied to a new domain.
Patience with things that don't work
Research trains you for a strange kind of patience. Most experiments don't work the first time. Most don't work the tenth time either. You learn to treat failure as information, not as a verdict on your competence.
I won't pretend that switching careers has been easy or that this patience makes learning to code frictionless. It doesn't. But I notice that when a script fails for the fifth time in a row, I don't spiral the way I might have if this were my first experience with something not working. I've been here before, just with different tools.
What I'm building now
Right now I'm working on LabTrack API, a FastAPI + PostgreSQL project for managing lab experiment data. It's a small, deliberate way of connecting both halves of my background: using the software skills I'm building now to solve a real problem I actually lived through in research.
I'm also getting more into applied AI, using tools like Claude Code to automate parts of my own workflow (including, a little ironically, my job search).
If you're also switching into tech from somewhere else
You're probably bringing more transferable skills than it feels like some days. The specific tools change, but the thinking underneath is often the same: isolate the problem, test a hypothesis, document what you learn, be patient with failure.
I'd love to hear from anyone else on a similar path. What did your previous field teach you that turned out to be surprisingly useful in tech?
