I'm a good fit if you need: - A full stack developer team for MVPs, admin dashboards, or CMS integrations - Laravel REST APIs with clean architecture and documentation - Vue.js front-ends with reusable components and Tailwind CSS - WordPress custom themes, plugin development, or web design overhauls - A reliable PHP developer for legacy refactoring or greenfield builds - Expert web developer guidance from concept to deployment Core tech: Laravel, Vue.js, WordPress, GraphQL, MySQL/PostgreSQL, Redis, REST API, JWT Auth, Tailwind CSS, Vuex/Pinia, Git, Docker, Elementor, PHP, JavaScript, HTML5, CSS Over the years as a full stack web developer, I've learned that the developer needs to understand the client's business goals to translate them into systems that actually move the needle. Whether you need a Laravel developer to architect a complex backend or a Vue.js developer to build an intuitive interface, my approach starts with listening. I ask questions that uncover the real problem, not just the surface symptoms. As a web developer who's seen projects succeed and fail, I know the difference usually comes down to clear communication, realistic timelines, and code that's maintainable six months from now. That's why I focus on documentation, testing, and knowledge transfer - so you're never locked into depending on me forever, even though many clients choose to keep working together for years. Team setup: I build teams tailored to your budget, timeline, and tech stack. You can lead directly or let our PM handle sprints - either way, you stay in control. Most devs have 5–7 years of hands-on experience; team leads bring 10+ years of deep industry knowledge. When projects require React, I collaborate with trusted React developer partners to ensure seamless delivery. Let's make your product better. Kind regards, Alexandra

👩‍💻 I’m a Vue.js Developer and Front-End Developer with more than 8 years of experience in web development. I build Vue.js web applications, single-page applications (SPA), progressive web apps (PWA), and responsive websites. My core stack includes Vue.js, Nuxt.js, JavaScript, TypeScript, HTML5, CSS3, SCSS, Vuex, Pinia, Bootstrap, Tailwind CSS, and Vuetify. Most of my clients hire me for Vue.js development because I focus on creating front-end applications that are scalable, maintainable, and optimized for performance. I also specialize in Figma to Vue conversion, PSD to HTML, responsive front-end development, and API integration. As a Vue.js Developer, I work with Vue 3, Nuxt.js, Vue Router, Composition API, and Pinia to build structured and maintainable applications. I handle state management with Vuex or Pinia, integrate REST APIs and GraphQL, and add real-time functionality with WebSockets and Firebase. For SEO and server-side rendering, I use Nuxt.js SSR, making applications fast-loading, SEO-friendly, and optimized for performance. I deliver responsive front-end development using HTML5, CSS3, SCSS, Tailwind CSS, Bootstrap, and Vuetify to ensure that every Vue.js application is mobile-first, user-friendly, and cross-browser compatible. My work often includes converting Figma and PSD designs into Vue.js applications, with attention to clean code, accessibility, and responsive UI development. To ensure code quality and stability, I apply unit testing and end-to-end testing with Cypress, Jest, Mocha/Chai, and Postman. This allows me to verify the functionality of every Vue.js project before it goes live, ensuring that each application is production-ready, stable, and scalable. Performance optimization is a core part of my workflow. I apply lazy loading, code splitting, caching, tree-shaking, and AOT compilation to make applications load quickly and run smoothly. For progressive web apps (PWA) I set up service workers, offline support, push notifications, and mobile-first optimization. With Nuxt.js and Vue.js Universal rendering, I ensure that applications are SEO-optimized and deliver excellent user experiences. 📂 Example Vue.js projects include: I built enterprise dashboards with Vue.js and Vuex, integrating APIs, role-based authentication, and real-time analytics. These dashboards supported thousands of concurrent users and were optimized for performance. I developed SaaS platforms with Vue 3 and Tailwind CSS, delivering admin dashboards with responsive UI, state management via Pinia, and full REST API integration. I created e-commerce platforms with Nuxt.js SSR, building storefronts with fast server-side rendering, responsive layouts, SEO-friendly pages, and smooth checkout flows. I performed migration of legacy Vue.js applications to Vue 3, applying the Composition API, TypeScript, and Pinia to modernize project structure and improve scalability. I developed real-time tracking systems with Vue.js and WebSockets, building dashboards with live updates, instant notifications, and interactive charts. I created custom UI component libraries using Vuetify and Tailwind CSS, delivering reusable Vue.js modules to accelerate development. For deployment and team collaboration, I use Git, GitHub Actions, GitLab CI/CD, Docker, Kubernetes, Webpack, and NPM. This ensures smooth delivery pipelines, effective teamwork, and scalable front-end architecture. I often collaborate with designers, backend developers, and QA engineers to deliver complete web application solutions. Clients choose me because I deliver high-quality Vue.js applications using JavaScript, TypeScript, HTML5, and CSS3. I integrate responsive design, API connections, state management, testing, and performance optimization into every project. I provide clear communication, reliable delivery, and maintainable front-end code. I combine Vue.js and Nuxt.js expertise with modern tools and optimization practices to ensure stability and long-term scalability. 📩 If you need a Vue.js Developer or Front-End Developer for Vue.js development, Nuxt.js applications, Figma to Vue conversion, responsive front-end development, SPA, PWA, or testing with Cypress and Jest, contact me. Let’s build your next Vue.js application, SaaS platform, dashboard, or e-commerce project together.
