After the phases
What to skip
These topics look useful but cost more time than they return. Review this list at every quarterly checkpoint, because tools in this field change fast.
Writing code by hand as a training goal
Build reading fluency and understand the concepts. Let agents type. The exception is a short, deliberate block of interview preparation.
Every new agent tool
A new multiplexer, editor, or agent appears most weeks. Use one tool per category, review the choice every quarter, and spend the rest of your attention on the patterns. Every candidate knows the tools. Judgement is what sets you apart.
Deep ML research before systems skills
You need enough machine learning to reason about model behaviour and inference. This roadmap targets platform engineering, so do not postpone production systems until you can train a transformer from scratch.
Collecting frameworks
Do not build one tutorial in every agent framework. Pick one or two after you have seen the underlying loop. Ask which concepts would still matter if the framework disappeared next year. Be careful with frameworks that hide a lot of prompting, such as CrewAI. You get a demo running in an hour, and then you struggle to debug it.
Prompt engineering on its own
Prompts matter, but reliable systems depend on retrieval, tool contracts, policy, structured output, evaluation, and tracing. Treat a prompt change like a code change: version it, evaluate it, and roll it out safely.
Certificates without production experience
An AWS certificate can give your study a structure. A running agent service on a queue, with least-privilege IAM and a game-day report, proves much more.
Kubernetes before you need it
The roles this roadmap targets rarely ask for it. Use the simplest runtime that fits the workload.
Tools to learn only when a job needs them
Learn durable execution, sandboxes, and gateways properly. Learn Aspire and LocalStack only well enough to apply for AWS and .NET platform roles. Do not study New Relic on its own, because OpenTelemetry covers what you need. Learn everything else when a specific job needs it.
