Full Stack Developer A complete roadmap to becoming a professional full stack developer. Starting from HTML, CSS, and JavaScript fundamentals, this path guides you through frontend frameworks, backend development, databases, APIs, security, testing, DevOps, cloud deployment, system design, and performance — culminating in portfolio building and career strategy.
12 milestones in this roadmap
Step 1 beginner 6-8 weeks
Programming Fundamentals (HTML/CSS/JS) Build a strong web foundation with semantic HTML5, responsive CSS3 layouts, and modern JavaScript ES6+ for DOM manipulation.
1 Semantic HTML5 elements and accessibility (ARIA roles, screen readers) 2 CSS Box Model, Flexbox, Grid, and responsive media queries 3 JavaScript ES6+: let/const, arrow functions, destructuring, modules 4 DOM manipulation, event handling, and the browser rendering pipeline 5 Fetch API, promises, async/await, and error handling 6 Web performance basics: critical rendering path, lazy loading
