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

Full Stack Developer with 12 years of experience and Team Lead delivering 30+ projects - your trusted long-term development and solution architecture partner specializing in React and Node.js
The code is invisible; the outcome is not ✨
With me:
- Autobound grew from one engineer to a 15-person team through 4+ years of our cooperation, raised more than $4M in funding, scaled to 50K+ active users and $8M ARR along the way.
- DriverHRIS evolved from a slow 1000-screen system into a fully rebuilt product serving 400+ dealerships, backed by an 18-person dev team, over 5+ years - page loads dropped 80%, support tickets cut in half.
- Augmento expanded from a prototype to a 15-person dev team in 3 years, powering AR experiences for 30+ global brands including Fortune 500 companies and securing $6M in investment.
- At Wawibox (Germany, dental-industry SaaS), I've led the engineering team for 3+ years - owning the full rewrite of the legacy Vue 2 platform into a modern Vue 3 / Nuxt 3 / Node.js / TypeScript / PostgreSQL stack without a single day of downtime for 2,000+ paying clinics across 3 countries.
🛠 Tech I work with:
Frontend — React · Next.js · Vue 3 · Nuxt 3 · TypeScript · JavaScript
Backend — Node.js · Python
Mobile — React Native · Flutter
Data & infra — PostgreSQL · Firebase · Supabase
AI & tooling — Claude · Claude Code · Cursor · LLM integrations · agentic workflows
I'm also an early and heavy Claude power-user - AI-assisted development is part of how I ship, not a novelty bolted on.
Cursor, Claude Code, agentic workflows, LLM integrations in production - I've been living in this stack since the day it existed.
Got a product to build, scale, or rescue?
Whether it's a new build, a team extension, or a legacy system that's slowing you down - message me and let's find a solution that actually fits your situation. 🤝

Looking for an experienced WordPress Developer, WooCommerce Developer, PHP Developer, Python Developer, Laravel Developer, or AI Developer who focuses on business results rather than simply delivering code? 👋 Hi, I'm Vlad.
As a WordPress Developer with 12+ years of experience, I've helped startups, ecommerce brands, SaaS companies, agencies, and established businesses build scalable websites and business platforms that generate measurable business results. During that time I've completed 123+ projects, delivered 4,181+ hours on Upwork, earned $100K+, and worked with clients across Europe, the US, Australia, Israel, and the Middle East.
Businesses hire me as their WordPress Developer because they need more than someone who can write code—they need a long-term technical partner who understands performance, scalability, security, SEO, and business growth.
Whether you're launching a new website, improving an existing platform, or automating business processes, I work as a WordPress Developer, WooCommerce Developer, Laravel Developer, Python Developer, and AI Developer, delivering reliable solutions designed for long-term success.
🚀 Most projects begin with WordPress Development or a Website Redesign, but many grow into complete business platforms with custom WooCommerce functionality, API Integration, AI automation, CRM connectivity, and ongoing product improvements.
As a WordPress Developer, I've built corporate websites, ecommerce stores, booking systems, multilingual websites, membership platforms, customer portals, marketplaces, SaaS platforms, and custom business applications using Elementor, Divi, ACF, WooCommerce, WPML, and custom WordPress solutions. Every WordPress Development project is built with Responsive Design, Page Speed Optimization, SEO best practices, and future scalability in mind.
Clients also choose me as their WordPress Developer for long-term website improvements, technical consulting, performance optimization, custom plugin development, Divi customization, ACF development, and complex API Integration.

Over the last few years, AI Development has become one of my fastest-growing areas of expertise. As a Forward Deployed Engineer FDE Python Developer, AI Developer, Laravel Developer, and WordPress Developer, I build solutions powered by OpenAI API, AI Agents, and Automated Workflows that automate customer support, document processing, reporting, market research, and internal operations.

🛰️ Built a platform for NASA Geochron
🎥 Shipped video streaming apps handling 100,000+ concurrent users
💰 Helped clients generate $1.5M+ in revenue through web and mobile products
📱 Delivered 100+ projects across web, React Native Mobile, and Node.js backends - startups, SaaS, fintech, healthcare, and B2B
I'm a Senior React Developer and Full Stack Developer React Node with 9+ years of experience on the frontend and hands-on backend experience building production-ready web, mobile, and server-side applications. As a Full Stack Developer React Node, I work across the entire stack - from MVP prototypes shipped in days to complex SaaS platforms built to scale.
Whether you need a React Developer for web application, a React Native Developer for your app, a Node.js backend, or all three - I build things that work, perform, and hold up in production.
🔧 Tech I work with daily:
React.js | Next.js | TypeScript | React Native | Node.js | Express.js | PostgreSQL | MongoDB | Redux | Zustand | Tailwind CSS | shadcn/ui | REST API | GraphQL | OpenAI API | WebSocket | Figma
🌟 What I actually do well
🔹 React & Next.js Web Applications
From SaaS dashboards and admin panels to marketplaces, fintech platforms, and B2B tools - I build clean, scalable frontend React frontends that real users rely on daily. As a React Developer, I get into existing codebases, not just greenfield projects.
🔹 Node.js Backend & API Development
As Full Stack Developer React Node, I have hands-on experience building REST APIs, GraphQL endpoints, authentication systems, background jobs, and database architecture using Node.js and Express. Backends designed to support the same scale and reliability standards as the frontends I ship.
🔹 React Native Mobile Apps
Cross-platform iOS and Android development using React Native. As a React Native Developer, I've shipped mobile apps to the App Store and Google Play, and I know the difference between demo-ready and production-ready.
🔹 MVP & Prototype Delivery
Startup mode is where I'm comfortable as well. As Full Stack Developer React Node I translate concepts into working React Next.js, Node.js, or React Native Mobile prototypes fast, without sacrificing the architecture decisions that matter later.
🔹 Real-Time & Complex UI
WebSocket integrations, live dashboards, streaming interfaces, real-time data flows - built and shipped across multiple platforms including a video streaming product at 100K+ concurrent users. As Full Stack Developer React Node, I take on each project with this same level of care.
🔹 AI-Powered Apps
OpenAI API integrations into web, mobile, and Node.js backend products - chat interfaces, AI assistants, content generation tools - built as production features, not demos. My work as a Full Stack Developer React Node means these are shipped as real, scalable, end-to-end features.
🔹 Figma to Production
Pixel-accurate implementation of Figma designs across React Next.js and React Native Mobile projects. As React Developer and React Native Developer I've worked directly with design teams and solo designers - I know how to read a design file and ask the right questions.
🔹 Performance & Code Quality
Core Web Vitals, bundle optimization, API performance, database query tuning, clean component and service architecture - I write Next.js TypeScript and Node.js code that the next developer can read and extend. Clean handoff is non-negotiable.
🏆 Delivered across 9+ years
🔸 NASA Geochron platform - complex data-driven web application
🔸 Video streaming platform - 100,000+ concurrent users
🔸 20+ SaaS products launched across multiple verticals
