Passionate about turning complex code into clear concepts. With over 3 years of experience at Barclays, I’ve spent my career building and scaling mission-critical data pipelines and automating massive cloud infrastructures. As a Senior Software Developer and AWS Certified Cloud Practitioner, I don't just write code—I architect solutions that save thousands in costs and deployment time. Beyond the corporate world, I’m a builder at heart. From creating real-time Discord monitors with 50ms agility to developing AI-driven mask detection models, I love exploring the "how" behind the tech.My Teaching Philosophy: I believe the best way to learn is by doing. Whether you are a beginner picking up Java or Python, or an aspiring engineer looking to master AWS and Cloud Computing, I’ll show you the industry secrets to writing production-ready code.

Core JAVA & Multithreading MASTERY Training by Gaurvendra Singh
The Core Java & Multithreading Mastery Course is an advanced online program designed for learners who want to gain deep expertise in Java programming, from fundamentals to multithreading and modern Java features. This course is ideal for computer science students, developers, and professionals aiming to strengthen their Java skills for academic, professional, or industry applications.
The course combines conceptual understanding, hands-on coding, and real-world applications to ensure learners not only understand Java syntax and object-oriented programming but also master modern Java 8+ features, collections, generics, and concurrency mechanisms. By the end of the course, students will be able to develop robust, scalable, and multithreaded Java applications confidently.
What Students Will Learn
Phase 1: Java Fundamentals & Environment Setup
The Big Picture: JDK vs. JRE vs. JVM; How Java achieves "Write Once, Run Anywhere."
Setup: Installing JDK 17/21, setting up IntelliJ IDEA/Eclipse, and Environment Variables.
Language Basics: Variables, Data Types (Primitives vs. Objects), and Type Casting.
Control Flow: If-Else, Switch (Modern Syntax), For/While/Do-While loops.
Memory Basics: Introduction to Stack vs. Heap memory.
Phase 2: Object-Oriented Programming (The 4 Pillars)
Classes & Objects: Defining blueprints, Constructors (Default vs. Parameterized).
Encapsulation: Using Private fields and Getters/Setters for data security.
Inheritance: Reusing code with
extendsandsuper.Polymorphism: Method Overloading vs. Method Overriding.
Abstraction: Abstract Classes vs. Interfaces (The "Contract" of programming).
Pro-Tip: Explain how Barclays uses Interfaces to define standard behaviours across different payment gateways.
Phase 3: Java Collections Framework (In-Depth)
List Interface: ArrayList vs. LinkedList vs. Vector (When to use which?).
Set Interface: HashSet (Internal working), LinkedHashSet, and TreeSet (Sorting).
Map Interface: HashMap (Buckets & Hashing), LinkedHashMap, and TreeMap.
Queue & Deque: PriorityQueue and ArrayDeque for specialised data flows.
Sorting: Using
ComparableandComparatorfor custom object sorting.
Phase 4: Exception Handling & Generics
Try-Catch-Finally: Managing Runtime vs. Compile-time errors.
Custom Exceptions: Creating your own exception classes for business logic.
Generics: Writing Type-Safe code and avoiding
ClassCastException.
Phase 5: Java 8+ Modern Features (The "Game Changers")
Lambda Expressions: Writing concise, functional code.
Functional Interfaces:
@FunctionalInterface, Predicate, Consumer, and Supplier.Stream API:
filter(),map(),reduce(), andcollect()for data processing.Optional Class: Eliminating the "Billion Dollar Mistake" (NullPointerExceptions).
Default & Static Methods: Adding logic to interfaces without breaking implementers.
Phase 6: Multithreading & Concurrency
Thread Basics: Creating threads via
Threadclass andRunnableinterface.Thread Lifecycle: Start, Run, Sleep, Join, and Wait/Notify.
Synchronisation: Locks,
synchronizedblocks, and preventing Race Conditions.Executor Framework: ThreadPools,
CallableandFuturefor professional async tasks.
