A 12-week parallel learning roadmap to become a job-ready fullstack Java developer in the AI era.

Fullstack Java Developer Roadmap

A 12-week parallel learning roadmap designed to get you an entry-level fullstack Java developer job in the AI era. No sequential slogging — learn 2–3 tracks simultaneously so you stay engaged and never get bored.

Why Parallel Learning?

Traditional roadmaps make you finish one skill before starting another. That's a recipe for boredom and burnout. Instead, this roadmap splits every phase into parallel tracks — work on backend in the morning, frontend in the afternoon, and DSA in the evening. You see connections early and stay motivated.

Timeline Overview

Phase	Weeks	Focus	Type
Phase 1	1–2	Java, HTML/CSS/JS, SQL, DSA Basics	🔄 Revision
Phase 2	3–6	Spring Boot, React + TS, MongoDB, DSA	🆕 New Skills
Phase 3	7–10	Next.js, Kafka, Redis, Docker, DSA	🆕 Advanced
Phase 4	11–12	AI Skills, Portfolio, Interview Prep	💼 Job Ready
