ROADMAPS(12)

[8 steps]Frontend Developer RoadmapFrom HTML fundamentals to production-grade frontend engineering with React, TypeScript, and modern tooling.[7 steps]Backend Developer RoadmapFrom API fundamentals to distributed systems. Build production backends with Node.js, databases, auth, and cloud deployment.[8 steps]DevOps and SRE RoadmapFrom Linux fundamentals to production-grade infrastructure. Master containers, orchestration, CI/CD, monitoring, and cloud platforms.[5 steps]AI Engineer RoadmapBuild products on top of foundation models: prompting, RAG, fine-tuning, and production-grade LLM systems. No model training from scratch required.[4 steps]ML Engineer RoadmapTrain, fine-tune, and ship machine learning models to production. Math foundations, deep learning, and model serving for engineers building models, not just calling APIs.[3 steps]MLOps Engineer RoadmapOwn the model lifecycle in production: experiment tracking, CI/CD for ML, monitoring, and governance.[4 steps]Agentic AI Engineer RoadmapBuild autonomous AI systems that plan, use tools, and act — beyond single-shot prompting.[4 steps]Data Scientist RoadmapStatistics, experimentation, and analysis to turn data into decisions — distinct from ML engineering's focus on shipping models.[4 steps]Computer Vision Engineer RoadmapBuild systems that understand images and video — from classification to detection to deployment.[4 steps]NLP Engineer RoadmapBuild systems that process and understand text at a deeper level than API-consumption — classification, NER, and custom language models.[4 steps]AI Infrastructure Engineer RoadmapBuild the systems that train and serve AI at scale — GPU clusters, distributed training, and inference optimization.[10 steps]Full-Stack Developer RoadmapBuild complete web applications from database to UI. Master frontend, backend, deployment, and everything in between.
