Introduction
Starting a career in software development after completing a BE in Computer Engineering can be an exciting yet challenging transition. For Sakshi Walunjkar, who graduated in 2025, the next step was to turn her academic understanding into practical development skills that could support her entry into the IT industry.
She joined 3RI Technologies’ Java Full Stack program to build that bridge through structured learning, hands-on projects, and exposure to technologies used across full-stack development. The program is designed around practical learning and includes 10 real-time projects, with topics ranging from Core Java and MySQL to JDBC, Servlets, Spring, Hibernate, Spring Boot, frontend technologies, Git, and project development.
As Sakshi progressed, each stage of learning gave her an opportunity to strengthen her programming foundation and apply concepts through practical work. Her journey eventually took her from being a fresh BE Computer graduate to starting her professional career as a Software Developer at Harbinger Group.
The Challenge
Coming directly from an academic background, Sakshi needed to connect her computer engineering knowledge with the practical skills expected in a development environment. Learning individual programming concepts is different from understanding how they work together while developing an application.This is where structured Java Classes in Pune can provide a practical learning path. For Sakshi, the focus was on strengthening:
- Core Java and object-oriented programming
- Database connectivity using MySQL and JDBC
- Web development with HTML, CSS and JavaScript
- Advanced Java, Hibernate, Spring and Spring Boot
- Git and application development practices
- Problem-solving and interview preparation
The challenge was therefore not simply learning Java, but developing the ability to apply different technologies together.
The Learning Approach at 3RI Technologies
Sakshi’s goal was to move beyond the programming concepts she had studied during her BE Computer degree and become more comfortable with actual software development. Her training at 3RI Technologies followed a practical path where each new concept was connected with exercises, assignments, and project work.
The Java Courses in Pune offered through the program are structured as a 5-month Java Full Stack course, covering the technologies a learner needs to understand both frontend and backend development. The program includes 10 real-time projects, giving students opportunities to practise what they learn rather than keeping the training limited to theory.Her learning covered:
- Java fundamentals: Core Java, OOPs, collections, exception handling, and multithreading
- Database skills: MySQL, SQL, and JDBC
- Frontend development: HTML, CSS, JavaScript, and Bootstrap
- Backend technologies: Servlets, JSP, and Hibernate
- Java frameworks: Spring and Spring Boot
- Application development: REST APIs and React basics
- Developer tools: Git and Postman
- Additional preparation: Aptitude, communication, interview preparation, and project work
- New-age development: AI-enabled Java development and Generative AI concepts
The projects gave Sakshi a chance to work with concepts in a more practical setting. Applications such as a User Registration System, To-Do List, Contact Manager, Student Result Portal, and Employee Directory helped bring classroom concepts closer to the type of development work learners may encounter in professional environments.

The Learning Path of Java Classes in Pune
For Sakshi, the journey was not about trying to learn every technology at once. It was about moving step by step—from strengthening programming fundamentals to understanding how different technologies work together in a real application. From 3RI Technologies’ point of view, this progression helps learners build a stronger foundation before moving into advanced Java and full-stack development. The 5-month program includes project-based learning and 10 real-time projects.
- Weeks 1–4 – Building the Foundation: The initial stage focused on programming fundamentals, computer concepts, operating systems, networking, Linux and database basics. MySQL and SQL helped create an understanding of how applications store and work with data.
- Weeks 5–8 – Understanding the Frontend: Sakshi moved into HTML, CSS, JavaScript, jQuery and Bootstrap. This stage helped her understand how the user-facing part of a web application is structured and how interactive elements work.
- Weeks 9–12 – Core Java and Application Logic: The focus then shifted to Core Java, including OOP concepts, classes and objects, inheritance, exception handling, collections, multithreading and modern Java features. This became an important foundation for the development work that followed.
- Weeks 13–16 – Advanced Java and Frameworks: Sakshi progressed into JDBC, Servlets, JSP and Hibernate before moving into Spring concepts such as dependency injection, Spring MVC and database integration. The curriculum also introduces AI-assisted approaches for areas such as CRUD development and debugging.
- Weeks 17–20 – Full Stack Development and Projects: The final stage brought the concepts together through Spring Boot, REST APIs, testing, Git, React and project work. Projects listed by 3RI Technologies include a User Registration System, To-Do List, Contact Manager, Student Result Portal, Login & Logout App and Employee Directory.
With this learning foundation and her own efforts in pursuing opportunities, Sakshi moved forward in her career and secured a role as a Software Developer at Harbinger Group. Her journey from a BE Computer graduate in 2025 to a professional software developer makes her experience particularly relevant for fresh graduates who are preparing to take their first step into the IT industry.
