core-development
Master core development paths: Frontend (3-6 mo), Backend (6-12 mo), Full Stack (6+ mo), DevOps (1-2 yr). Get learning sequences and tech stacks.
When & Why to Use This Skill
The Core Development skill is a comprehensive career roadmap generator designed to guide aspiring and professional developers through structured learning paths for Frontend, Backend, Full Stack, and DevOps. It provides curated 2025 technology stacks, estimated learning timelines, and actionable troubleshooting advice to help users navigate the transition from beginner to industry-ready engineer. By offering clear milestones and validation checklists, it eliminates 'tutorial hell' and ensures learners focus on high-impact, modern technologies.
Use Cases
- Career Path Selection: Helping beginners decide between Frontend, Backend, Full Stack, or DevOps based on their interests in visual design, logic, or infrastructure.
- Curriculum Planning: Providing structured, week-by-week learning sequences for mastering modern frameworks like React 19, FastAPI, or Kubernetes.
- Tech Stack Recommendation: Offering up-to-date 2025 technology suggestions (e.g., Next.js 15, Tailwind v4, Vite) for developers starting new projects or upgrading their skills.
- Skill Gap Analysis: Using the validation checklists and troubleshooting trees to identify and fix weaknesses in a developer's current knowledge base before job hunting.
- Professional Pivoting: Assisting experienced developers in transitioning from one domain to another (e.g., moving from Frontend to DevOps) with a clear transition roadmap.

Troubleshooting Decision Tree
Which path should I choose?
├─► Like visual/creative work? → Frontend
├─► Prefer logic/algorithms? → Backend
├─► Want to build complete products? → Full Stack
└─► Love automation/infrastructure? → DevOps
Stuck in tutorial hell?
├─► Stop watching, start building
├─► Pick ONE project and finish it
├─► 70% building, 30% learning
└─► Deploy something live today
Can't find a job?
├─► Portfolio too weak? → Build 3 real projects
├─► No GitHub activity? → Contribute to open source
├─► Resume weak? → Add measurable achievements
└─► No network? → Join communities, attend meetups
Common Failure Modes
| Symptom | Root Cause | Recovery Action |
|---|---|---|
| Analysis paralysis | Too many options | Pick popular stack, start today |
| Outdated learning | Using old resources | Check resource date (must be 2024+) |
| Impostor syndrome | Comparing to experts | Focus on daily improvement |
| Burnout | Too fast, too much | 1-2 hours/day consistently |
Validation Checklist
Before marking path complete:
- Can build project from scratch without tutorial
