Hi, I'm Amarjeet, a B.Tech Computer Science student passionate about software engineering, full stack development, problem-solving, and building practical projects. I am exploring and building my skills across Java Full Stack Development, Spring Boot, MERN Stack, Data Structures & Algorithms (DSA), Low-Level Design (LLD), High-Level Design (HLD), and System Design. My goal is to make technical learning easier for students and beginners through practical guidance, structured learning roadmaps, project discussions, coding practice, and placement preparation. 🚀 **TECHNICAL DOMAINS** **1. Java Development** • Core Java and Object-Oriented Programming (OOP) • Classes, Objects, Inheritance, Polymorphism, Abstraction, and Encapsulation • Collections Framework, Generics, Exception Handling, and Strings • Multithreading, Java 8+ features, Streams, and Lambda Expressions • Clean Code and basic software development principles **2. Java Backend Development** • Spring Framework and Spring Boot • REST API development and HTTP methods • Spring MVC and layered architecture • Spring Data JPA and Hibernate • MySQL and relational database integration • Validation, exception handling, and API documentation • Spring Security, authentication, authorization, and JWT • Maven, Postman, and backend debugging **3. MERN Stack Development** • MongoDB — NoSQL database, CRUD operations, schemas, and aggregation • Express.js — routing, middleware, REST APIs, and backend architecture • React.js — components, props, state, hooks, forms, and routing • Node.js — asynchronous programming, modules, and server-side development • Mongoose, API integration, authentication, and authorization • Full stack application development and deployment **4. Frontend Development** • HTML5, CSS3, JavaScript, and responsive design • DOM manipulation and modern JavaScript • React.js, component-based architecture, and reusable UI • Next.js fundamentals, routing, rendering, and full stack features • TypeScript fundamentals • Form handling, validation, API integration, and user experience **5. Database and Data Management** • SQL, joins, subqueries, indexes, and database design • MySQL and MongoDB • Database relationships and schema design • Transactions, normalization, and query optimization fundamentals • Prisma ORM fundamentals **6. Data Structures & Algorithms** • Arrays, Strings, Hashing, and Two Pointers • Sliding Window and Binary Search • Linked Lists, Stacks, and Queues • Trees, Binary Search Trees, and Heaps • Recursion and Backtracking • Greedy Algorithms and Dynamic Programming • Graphs and graph traversal • Time and Space Complexity • Coding interview practice using Java **7. Low-Level Design (LLD)** • Object-Oriented Design Principles • SOLID Principles • UML and class diagrams • Common Design Patterns • Class relationships and interface-based design • Designing maintainable and extensible applications • Practical object-oriented design exercises **8. High-Level Design (HLD) & System Design** • Client-server architecture • Monolithic and microservices architecture • Load balancing and caching • Database scaling and replication fundamentals • SQL vs NoSQL trade-offs • REST API design • Message queues and asynchronous processing • Scalability, availability, reliability, and fault tolerance • System design fundamentals and architecture discussions **9. Developer Tools and Workflow** • Git and GitHub • Git branching, commits, pull requests, and collaboration • VS Code and IntelliJ IDEA • Postman and API testing • Maven and npm • Environment variables and application configuration • Debugging, deployment, and project documentation **10. Placement and Career Preparation** • Java and DSA learning roadmaps • Full stack development learning plans • Project selection and portfolio improvement • GitHub profile and README reviews • Resume improvement and project presentation • Technical interview practice • LLD, HLD, and system design learning roadmaps • Consistent coding practice and preparation strategies 🤝 **HOW I CAN HELP** I can share beginner-friendly guidance, learning resources, project feedback, study roadmaps, coding practice strategies, and placement preparation suggestions based on my learning and project experience. Whether you are starting with Java, exploring Spring Boot, building MERN applications, practicing DSA, or learning system design, the goal is to help you understand concepts and follow a structured learning path. Let's learn, build, solve problems, and grow together!
