Sajith22/README.md

👋 Hi, I'm Sajith Wickramasinghe (@Sajith22)

I'm a 4th-year Software Engineering student from Sri Lanka, currently interning as a Intern Backend Engineer (NestJS) at CodeSys (Pvt) Ltd. I'm passionate about building efficient, scalable applications and enjoy exploring new technologies.

👀 Interests

  • Learning new languages and technologies — Rust, Go, Python, and cloud platforms like AWS/Azure
  • Backend development combined with DevOps practices
  • Applying first-principles thinking to learn new concepts deeply
  • Full-stack web development and cross-platform mobile development (Flutter)

🌱 Currently Exploring

  • Advanced NestJS architecture patterns and TypeScript best practices
  • DevOps fundamentals — Docker, CI/CD pipelines, and cloud deployment
  • AI/LLM integration — prompt engineering, RAG, and agentic workflows

💼 Projects

Here are some of my recent works:

  • BidForge (NestJS · Flutter · React · Firebase · Railway) — A real-time auction platform with a NestJS backend API, Flutter mobile app, and React admin dashboard. Features live bidding, role-based access control, and cloud deployment on Railway.
  • UniVax (Express.js · MongoDB · React · Tailwind CSS) — A university immunization tracking system with JWT authentication, RBAC, automated email notifications via Brevo, and a full-stack web interface.
  • Calendar Project — A calendar app built with HTML, CSS, JavaScript, and PHP.
  • Intro to Backend — Early exploration of backend development and DevOps integration with JavaScript.
  • DiTec Final Project — A C#-based desktop application.
  • Collaborating on Mind Matters Project — A JavaScript-driven mental health initiative.
