Program Overview

Enterprise Architecture.
Production Scale.

This isn't just theory. From week one you'll be building real microservices on production-grade codebases ? working with Spring Boot backends, Angular/React frontends, cloud deployments, and the same tooling used at Fortune 500 companies.

We built this program around the skills enterprise employers actually hire for: clean architecture, Spring Security, REST and GraphQL APIs, Kubernetes deployments, and the confidence to design systems at scale.

What You'll Learn

Six Core Skill Domains

A curriculum crafted with input from senior Java architects at enterprise software companies and SaaS product teams.

☕

Spring Boot & REST APIs

Build production-ready REST APIs with Spring Boot, Spring MVC, and Spring Data JPA. Master dependency injection, layered architecture, and exception handling.

Spring BootJPAHibernate

🖥️

Frontend Integration

Build dynamic UIs with Angular and React. Component architecture, RxJS, routing, state management, and consuming Java REST APIs with type-safe HTTP clients.

AngularReactTypeScript

🔐

Security & Auth

Implement enterprise-grade security using Spring Security, JWT, OAuth2.0, and role-based access control. Protect APIs from common attack vectors.

Program Timeline

Your Journey, Month by Month

A structured ramp from Java fundamentals to shipping enterprise-grade microservices.

MONTH 1

Java Mastery & Spring Foundations

Deep-dive into Java OOP, collections, and streams. Set up Spring Boot projects, understand the IoC container, build your first REST endpoints, and connect to PostgreSQL with Spring Data JPA.

MONTH 2

Security, Auth & Frontend

Implement Spring Security with JWT and OAuth2. Build an Angular or React frontend that authenticates against your API. Write integration tests and connect to a Redis cache layer.

MONTHS 3?4

Full-Stack Feature Development

Own end-to-end features within a team project. Database optimisation, async messaging with Kafka, file uploads to S3, and containerising your application stack with Docker Compose.

MONTHS 5?6

Microservices & Cloud Deployment

Decompose the monolith into microservices with Spring Cloud. Set up Kubernetes deployments on AWS EKS, configure CI/CD pipelines, implement distributed tracing, and monitor with Prometheus and Grafana.

GRADUATION

Architecture Demo & Certification

Present your capstone microservices project to industry guests, walk through your system design decisions, and receive your verified certificate, LinkedIn endorsement, and referrals to Spypro's hiring partners.
