Technologies & Frameworks:
Complete 4-Course Curriculum
Every course builds systematically on previous foundations, transitioning learners from theory to production systems.
Java Programming Fundamentals: From Zero to Java Developer
Master Java 21 from scratch: syntax, OOP, data structures, and a professional dev setup
Your complete on-ramp to Java programming. Starting from zero, no assumed knowledge, this course walks you through installing JDK 21, configuring a professional IDE, and progressively mastering the Java language: variables, control flow, methods, object-oriented design, Java 21 Records and Sealed Classes, pattern matching, collections, exception handling, and an introduction to Maven and Gradle. By the end, you will be fully equipped to tackle the Enterprise Spring Boot Architecture Blueprint (JAVA-201).
Enterprise Spring Boot Architecture Blueprint
Foundational 5-layer enterprise backend architecture on Java 21 LTS and Spring Boot 3.3
Establish an unshakeable architectural foundation. Build a 5-layer production Spring Boot 3.3 system incorporating Java 21 Virtual Threads (Loom), Flyway migrations, BigDecimal financial rounding, JPA @Version optimistic concurrency, AES-GCM field encryption, stateless JWT filters, Redis caching with write-eviction, Resilience4j circuit breakers, and Testcontainers integration tests.
Backend System Design in Practice: Reference Implementation
Architectural decision records (ADRs), concurrency race mechanics, and pre-flight auditing
Deconstruct the engineering trade-offs behind mission-critical systems. Using the companion Fintech Ledger API, analyze why layered architecture beats microservices for early teams, reproduce and eradicate lost-update bugs under 5,000 req/sec thread contention, and execute an exhaustive 50-point production pre-flight audit.
Java Backend Production Cookbook & Advanced Recipes
28 production-ready implementation recipes for high-throughput distributed architectures
An operational war-chest of 28 battle-tested recipes with complete code. Includes automated k6 and Gatling load tests, Keycloak single sign-on federation, OpenTelemetry distributed tracing across microservices, PostgreSQL WAL disaster recovery drills, and blue-green zero-downtime deployment pipelines.
Graduate with Defensible GitHub Artifacts
Employers and hiring managers don't want to hear about multiple choice test scores. When you complete this track, you walk away with real, production-tested deliverables: code repositories, security review bundles, and system designs that demonstrate your expertise.
