Vetted Developer in South Africa (UTC+2)

I have over 7 years of experience working with JavaScript, including modern ES6+ syntax such as arrow functions, promises, async/await, closures, and event delegation. For front-end development, I have expertise in React.js (React Router, Redux, Context API), Vue, jQuery, and TailwindCSS for styling. On the backend, I have utilized Node.js and Express.js to build features like authentication and authorization. I also have a strong grasp of TypeScript. I focus on improving JavaScript applications with static types, setting up configurations, debugging type errors, and designing interfaces for enhanced type safety. For distributed systems, I have implemented microservices architectures with inter-service communication via HTTP/REST and employed load-balancing techniques. My cloud experience primarily involves AWS services, including EC2 and Lambda, and basic CI/CD setups using GitHub Actions. Additionally, I have used Docker for containerizing React and Node.js applications, Redis for caching to reduce API load times, and GraphQL for efficient data fetching In testing, I am skilled in writing unit tests and performing integration tests.
