Hi, I'm Joshua 👋

Junior Backend Developer | Core Java & Spring Boot Ecosystem

I'm a logic-driven backend developer focused on building secure, robust, and enterprise-grad web application. After building a strong foundation in PHP, Laravel and SQL, I am currently aligning my entire tech stack with the Java ecosystem - focusing on Core Java logig, OOP architecture, automated unit testing, and Spring Boot APIs.

Backend engineering is where I excel. I thrive on structural validation, database engineering, automated testing guardrails, and data flow.


🔧 Tech Stack

The Java Ecosystem (Active Core Focus):

  • Java Core · Object-Oriented Programming (OOP) logic · IntelliJ IDEA Ecosystem
  • Automated Testing (JUnit 5 basics, unit testing business logic)
  • Spring Boot Framework (Currently learning: Dependency Injection, Spring Data JPA, REST APIs)

The PHP Foundation (Proven Production Knowledge):

  • PHP · Laravel · MySQL · PDO
  • Session-based Authentication · Custom Request Validation · MVC Architecture
  • Server-side File Handling · CSV Data Processing

Frontend:

  • JavaScript (API handling, async logic)
  • React + TypeScript basics
  • HTML · CSS · Bulma

Tools:

  • Git & GitHub
  • VS Code
  • IntelliJ

📌 Featured Projects & Active Engineering

Here is the core application I am actively developing, alongside a selection of completed backend projects that demonstrate my architectural foundation.

🛡️ Citizen Vaccine Appointment Manager (CVAM) — 🚀 Active Focus (Work-in-Progress) Java Core / Spring Boot Project

A centralized, enterprise-modeled system built to simulate public-sector logistics. This project serves as my main environment for mastering clean Java logic, automated testing validation layers, and integration with Spring Boot APIs and relational databases.

📚 Inclusive Inc — Full-Stack Exam Project (Laravel + MySQL)

A complete media management architecture featuring email verification, secure multi-user authentication, live search components, dynamic category filtering, and relational storage.

🔐 Members Only v2 — Refactored Authentication App

An architecture refactoring project focusing on session-based security, secure password hashing mechanics, and robust GUMP server-side data validation.

📄 Application Form v2 — Refactored Backend Form

A targeted backend processing script implementing custom server-side validation rules, secure multi-format file uploads, and continuous CSV data persistence.


🧠 What I'm Currently Focusing On

  • Mastering Unit Testing patterns inside Java utilizing JUnit to ensure regression safety.
  • Building out the core REST API controllers and Spring Data JPA repositories for the CVAM project.
  • Preparing for entry-level backend engineering roles (ST1) within structural, industrial, or enterprise environments.

✨ About Me

  • I write clear, organized code with highly maintainable functions.
  • I refactor projects to make them cleaner and more maintainable.
  • Backend logic gives me that “click” feeling — it behaves according to explicit rules.
  • I’m actively preparing for my first backend developer role.
