An order worth learning it in
A list of ten skills is the same unhelpful answer a catalogue gives, just sorted. This is where to actually start.
Start here
Essential to the role, and reachable from a standing start. Everything below rests on these.
- Performance bottleneck analysis
- Application Performance Monitoring (APM) tools
- Linux system profiling
- SQL
- CI/CD integration
Then this
The rest of what the role is assessed on. Harder, and it builds on the foundation above.
- JMeter
What sets you apart
Not what gets you hired, but what separates doing the job from being trusted with it.
- Kubernetes
- Workload modeling
You almost certainly have some of this already.
That is the point of starting from the role rather than a course. Upskili checks what you can do, then builds a path across only the gap.
