Sayak Ganguly

I am an experienced Software Engineer and Technology Professional with strong industry experience in designing, developing, and maintaining enterprise-level software applications. I specialize in Java-based backend development and full-stack application development, with hands-on experience across multiple technologies and software engineering practices.

My technical expertise includes:

• Core Java & Advanced Java
• Object-Oriented Programming (OOP)
• Java 8+ / Modern Java
• Collections, Multithreading, Exception Handling & Generics
• Data Structures & Algorithms
• Spring, Spring Boot & Spring MVC
• REST APIs & Microservices
• Hibernate / JPA
• React & JavaScript
• Angular & TypeScript
• HTML, CSS & Web Development
• Oracle & MySQL
• MongoDB & NoSQL Databases
• SQL & Database Design
• System Design & Software Architecture
• Design Patterns & SOLID Principles
• Distributed Systems & Microservices Architecture
• Git, CI/CD and software development practices
• Full-Stack Java Development
• Coding, Problem Solving & Debugging

I teach engineering students, fresh graduates, and working professionals with a strong focus on practical understanding. My teaching methodology combines concepts + coding examples + real-world scenarios + interview-oriented problem solving.

Instead of simply explaining definitions, I focus on helping students understand how technologies are actually used in professional software projects. For example, while teaching Spring Boot, I can take a student from creating a basic REST API to building a complete layered application with database integration, authentication, exception handling, and microservices concepts.

I can also help students understand System Design from the fundamentals, including HLD, LLD, scalability, APIs, databases, caching, messaging, load balancing, microservices, design patterns, and real-world architecture decisions.

My objective is to help students develop strong programming fundamentals, build projects confidently, improve problem-solving skills, prepare for technical interviews, and become industry-ready software engineers.
