I am a Software Engineer with a focus on backend development, primarily using Node.js and NestJS. I am continuously learning new technologies, contributing to open-source projects, and exploring freelance opportunities. My goal is to build clean, scalable, and maintainable software while improving my skills across the software engineering ecosystem.

• Build a Spring Boot REST API with CRUD operations
• Add JWT Authentication (access + refresh tokens)
• Integrate Redis caching for frequently accessed endpoints
• Publish messages using Kafka Producer / Consumer
• Write unit tests for services and controllers

• Containerize an application using Docker
• Deploy a backend service on AWS (EC2 or ECS)
• Create a CI/CD pipeline with GitHub Actions
• Deploy a containerized app to Kubernetes

• Build a React dashboard consuming a backend API
• Create a React Native Android app
• Package a desktop app using Electron

• Analyze a dataset using NumPy
• Build a small data analysis notebook with Pandas

A structured path of NestJS backend projects to grow from beginner to advanced.

Goal: Learn NestJS core concepts and clean architecture. Tech Stack: NestJS • TypeScript • PostgreSQL • TypeORM • class-validator • Swagger Features:

• Modular NestJS architecture
• CRUD APIs
• DTO validation and transformation
• Global exception filters
• API documentation with Swagger

Learning Steps:

1. Understand NestJS modules, controllers, and services
2. Implement basic CRUD operations
3. Apply validation and transformation using DTOs
4. Handle exceptions globally
5. Document APIs using Swagger

Goal: Build secure, production-ready authentication for APIs. Tech Stack: NestJS • PostgreSQL • Prisma ORM • JWT • bcrypt • Passport.js Features:

• User registration and login
• JWT authentication
• Role-based access control (RBAC)
• Refresh token rotation
• Secure password hashing

Learning Steps:

1. Implement user registration and login
2. Set up JWT-based authentication
3. Add role-based access control
4. Implement refresh token rotation
5. Secure passwords with hashing

Goal: Improve backend performance and scalability. Tech Stack: NestJS • Redis • Cache Manager • PostgreSQL • Docker Features:

• Redis caching for read-heavy endpoints
• Cache invalidation strategies
• Rate limiting
• Response compression
• Dockerized services

Learning Steps:

1. Integrate Redis caching into endpoints
2. Implement cache invalidation strategies
3. Add rate limiting for APIs
4. Compress API responses for efficiency
5. Dockerize the application for deployment

Goal: Learn distributed systems and asynchronous communication. Tech Stack: NestJS • Apache Kafka • PostgreSQL • Prisma • Docker Compose Features:

• Kafka producer and consumer services
• Asynchronous event handling
• Retry and dead-letter queue handling
• Service-to-service communication
• Centralized logging

Learning Steps:

1. Implement Kafka producers and consumers
2. Handle events asynchronously
3. Set up retry and dead-letter queues
4. Connect multiple services for event-based communication
5. Implement centralized logging for monitoring

Goal: Deploy backend applications professionally. Tech Stack: NestJS • Docker • GitHub Actions • AWS (EC2 / ECS) • Nginx Features:

• CI/CD pipeline with GitHub Actions
• Docker image build and push
• Environment-based configuration
• Production deployment on AWS
• Reverse proxy with Nginx

Learning Steps:

1. Set up GitHub Actions for CI/CD
2. Build and push Docker images
3. Manage environment configurations
4. Deploy services on AWS
5. Configure Nginx as a reverse proxy

Goal: Combine all previous concepts into a real-world backend system. Tech Stack: NestJS Monorepo • PostgreSQL • Redis • Kafka • Kubernetes • Prometheus & Grafana Features:

• Microservices architecture
• Distributed caching
• Observability with metrics and logs
• Horizontal scaling
• Zero-downtime deployments

Learning Steps:

1. Design a microservices architecture
2. Implement distributed caching strategies
3. Set up monitoring with Prometheus and Grafana
4. Implement horizontal scaling
5. Configure zero-downtime deployments
