I'm Alexandra - a full stack web developer who builds scalable platforms that work reliably from day one. I help startups and established businesses launch MVPs, modernize legacy systems, and scale products with clean architecture. The result? Production-ready Laravel APIs, Vue.js dashboards, and WordPress solutions that accelerate growth and free you from messy code forever. I'm a full stack web developer with 12+ years delivering production-ready solutions. 100+ projects shipped | Top-Rated with 100% Job Success Score since day one on Upwork | Long-term partnerships with clients across the US, EU & Middle East. I lead a focused team of seasoned developers - Laravel developer specialists, Vue.js developer experts, front end developer talent, and WordPress developer veterans who ship working software on time. 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 don’t just generate code quickly. I build systems that stay stable and production-ready as products scale.
