About Me :-

Building Scalable Web Applications with React.js & Ruby on Rails

Hi, I'm Kamal Joshi, a Full Stack Developer with 3.5+ years of experience building scalable and high-performance web applications using React.js, TypeScript, and Ruby on Rails. I specialize in developing secure, reliable, and efficient full-stack solutions that solve real business problems.

My core expertise lies in full-stack development, where I design responsive user interfaces with React.js and build robust backend systems using Ruby on Rails. I follow clean architecture practices including MVC architecture, SOLID principles, and build RESTful APIs for seamless frontend-backend integration.

I have hands-on experience with modern frontend technologies such as React.js, TypeScript, JavaScript (ES6+), HTML5, CSS3, Tailwind CSS, and Bootstrap. I also work with Micro Frontend architecture to build scalable and maintainable front-end systems.

On the backend, I work extensively with Ruby on Rails, focusing on API development, database design, authentication systems, and performance optimization. I have strong experience working with PostgreSQL and MySQL, including indexing, query optimization, and efficient schema design.

  • Authentication & Security: Devise, JWT, RBAC
  • Background Jobs: Sidekiq, Active Job
  • Database: PostgreSQL, MySQL, Supabase, SQL queries & optimization
  • Testing: RSpec, TDD/BDD practices, FactoryBot, Capybara
  • Version Control: Git, GitHub, GitLab, Bitbucket
  • CI/CD & Deployment: AWS, Netlify, Render, Vercel, GitHub Actions
  • Frontend: React.js, TypeScript, React Native, JavaScript/ES6, HTML5, CSS3, Tailwind, Bootstrap
  • Tools & Collaboration: Jira, Agile/Scrum, Odoo, Trello, Slack, Postman, VS Code
  • Performance Optimization: Redis, caching strategies, N+1 query optimization

I am passionate about writing clean, maintainable code and continuously improving my skills. I enjoy working in collaborative environments and contributing to building scalable, reliable, and user-centric software products.
