Technologies
I have strong expertise in JavaScript, including ES6+ features, DOM manipulation, event handling, and asynchronous programming (Promises, async/await). I can build fully interactive web applications, optimize performance, and implement clean, reusable code structures.
Proficient in building modern, scalable applications with React. I work with functional components, hooks (useState, useEffect, useMemo, useCallback), React Router, and Context API. Experienced in state management with Redux Toolkit and creating responsive, reusable UI components.
Proficient in using Redux Toolkit for modern and scalable state management in React applications. Skilled in creating slices, reducers, and asynchronous thunks with createAsyncThunk for handling API calls. I can implement middleware for tasks like localStorage sync, optimize performance with selectors and memoization, and structure Redux logic cleanly for maintainable and efficient applications.
Experienced in consuming and designing RESTful APIs using clear resource models and HTTP methods (GET, POST, PUT/PATCH, DELETE). Comfortable with authentication (JWT), status codes, pagination/filtering, and robust error handling. Use fetch/axios with async/await, test via Postman.
Skilled in creating fully responsive layouts using CSS, CSS3, Flexbox, and Grid. I apply a mobile-first approach with media queries, fluid typography (clamp, rem, vw), and responsive images (srcset, sizes) to ensure seamless user experience across all devices. Focused on performance optimization, accessibility, and modern UI/UX practices for building adaptive and visually consistent interfaces.
Proficient in Bootstrap framework for building responsive, mobile-first websites quickly. I can customize Bootstrap components, grids, utilities, and integrate them seamlessly into projects. Experienced in extending Bootstrap with custom CSS for unique, professional designs.
Experienced in using Tailwind CSS for creating highly customizable and responsive designs with utility-first classes. I can rapidly build modern UIs, apply dark/light modes, and extend the Tailwind configuration to match specific design systems and brand guidelines.
Experienced in using jQuery for DOM traversal, animations, and AJAX requests. Although I focus on modern JavaScript and React, I can work with jQuery for legacy projects, quick prototyping, or enhancing existing websites with dynamic functionality.

About Me
My name is Aghasalim Musayev
I am a Frontend Developer who creates modern, responsive and user-friendly web applications. My focus is on clean code, performance optimization and delivering smooth user experiences.
Skilled with HTML5, CSS3 (Flexbox, Grid), JavaScript (ES6+), React.js, Redux Toolkit, RESTful APIs, jQuery, Bootstrap, Tailwind CSS and modern development workflows. I have strong knowledge of building responsive and cross-browser compatible layouts, applying best practices in UI/UX design, performance optimization and ensuring accessibility.
I can design and develop scalable, reusable components with React, manage application state efficiently with Redux Toolkit, and integrate APIs with Axios or Fetch. I am experienced in responsive design principles, creating adaptive interfaces for mobile and desktop, and customizing frameworks like Bootstrap and Tailwind for unique designs.
I also work with version control (Git/GitHub), package managers (NPM/Yarn), and tools like Postman, VS Code, Figma to ensure smooth development. Continuously improving my skills, I stay updated with the latest frontend technologies and love turning ideas into real-world, high-quality projects.
I am currently learning TypeScript to write safer and more scalable applications. At the same time, I am pursuing formal education in backend technologies such as Node.js, Express.js, and databases (MongoDB, PostgreSQL). My goal is to strengthen my full-stack development skills by combining my frontend experience with backend knowledge, enabling me to build complete, end-to-end solutions.
