I believe in deep understanding, daily consistency, and building things the right way.
I'm a Software Engineer currently undergoing a self-driven
6-month AI Engineer Transformation Program — structured, disciplined, and documented publicly.
I’m not just learning syntax.
I’m learning:
- Deep system-level engineering
- Backend development with Java & Spring Boot
- Python for AI/ML
- Clean architecture principles
- Data structures & algorithms
- Real-world project building
- Professional Git & documentation practices
Every day is documented in my repo:
👉 https://github.com/JohnSunny21/AIEngineerJourney
- 📅 Currently on: Day 2 — Java Collections (Deep Dive)
- 🔥 Learning HashMap internals, hashing, treeification, memory layout
- 🛠️ Building a Student Management System (Java)
- 🧠 Practicing system-level thinking
- ⌨️ Daily typing, coding, problem-solving discipline
- Java
- Python
- JavaScript
- SQL
- Spring Boot
- REST API development
- JPA / Hibernate
- Git & GitHub
- IntelliJ IDEA
- Maven / Gradle
- Clean Architecture
- Unit Testing (JUnit/Mockito) (upcoming)
- Python for AI
- NumPy, Pandas (upcoming)
- Machine Learning (upcoming)
A 6-month structured transformation plan.
Each day includes deep explanations, hands-on coding, and system-level understanding.
It’s not a tutorial repo.
It’s a journey of mastery.
