Backend Ultimate 1.0
Spring Boot To Production: Master Backend Engineering With Java, Microservices, Kafka, Redis, Docker, Kubernetes, Spring AI And System Design
A focused backend roadmap for Java learners who want to move beyond CRUD APIs. Build secure REST APIs, database-backed systems, event-driven services, AI-powered backend workflows and production-style projects with live guidance and review.
Recommended for learners who know Core Java basics and want a serious backend path covering APIs, security, data, AI, distributed systems, DevOps and project explanation.

04
Ticket Booking Backend like BookMyShow
Shows, seat maps, booking locks, payment timeout and concurrency-safe reservation flow.
- Seat locking, booking lifecycle and status handling
- Redis locks, transactions and concurrency control
05
Cloud Storage Backend like Google Drive
File upload, folder hierarchy, access control, sharing links, versioning and search-ready metadata.
