AI-Leveraged Delivery — ship 2× faster ⚡ Most developers say they're "fast." Then the staging environment shows up in week six. I do it differently — and I can show you the receipts. 🧾 ◆ 100% Job Success Score | Top Rated Plus | Full Stack Developer | React Next.js | Front End Developer ◆ I've been doing Software Development for 8+ years. In that time I've worked on everything from quick Landing Pages to multi-year SaaS platforms - and the thing that's stayed consistent is that clients get a working product, not a list of reasons why it's late. I work as a Full Stack Developer and Front End Developer, which means I'm comfortable owning the whole thing. React and Next.js are where I spend most of my time, but the stack goes deeper: Node.js, Python, PHP, Laravel, TypeScript, MongoDB, MySQL, PostgreSQL, SQL - whatever the project actually needs. I don't have a favourite technology. I have a favourite outcome: software that ships and works. ◆ FRONT-END DEVELOPMENT Front-End Development is my home base. I work with React, Next.js, Vue.js, Angular, JavaScript, TypeScript, HTML, HTML5, CSS, CSS 3, Bootstrap, jQuery, Redux, and Workbox.js for PWA builds. Web Design and Responsive Design aren't an afterthought - I work from Figma and Adobe Photoshop and care about how things look and feel across every device. PSD to HTML conversion, Front-End Development Framework setup, pixel-accurate implementation - all part of the job. ◆ FULL-STACK & BACK-END As a Full Stack Developer I connect the front end to a real backend: Node.js, Python, PHP, Laravel, NestJS, REST API, API Integration, SQL, MySQL, MongoDB, Database Architecture, Git, CI/CD. I've set up auth systems, payment flows via Stripe, third-party API Integration, and backend logic that doesn't fall over when traffic spikes. ◆ WHAT I BUILD ◆ SaaS platforms and Web Applications - React, Next.js, TypeScript, Redux, Tailwind, clean Web Design, fast load times, and Responsive Design that holds up on every screen ◆ AI-powered products - RAG pipelines, chatbots, OpenAI and Claude API Integration, document processing tools, pgvector retrieval ◆ E-commerce and WordPress - WooCommerce, custom themes and plugins, PSD to HTML, Web Development that converts ◆ Landing Pages and marketing sites - HTML5, CSS 3, Bootstrap, jQuery, Responsive Design, conversion-focused Web Design built for speed ◆ React Native mobile apps - cross-platform iOS and Android, shared codebase, App Store and Google Play ◆ Web Developer work across the full stack - API, Database Architecture, Laravel and PHP backends, Node.js services ◆ INDUSTRIES I've shipped projects across fintech and payments, healthcare and medical platforms, e-commerce and retail, EdTech, real estate, logistics and delivery, SaaS and B2B tools, marketplaces, social platforms, media and streaming, legal tech, travel and booking, fitness and wellness, and non-profit. Most verticals at this point. ◆ HOW I WORK I communicate early and directly. If scope is unclear I'll say so before we start, not after week four. If an approach won't work I'll tell you - and offer an alternative. Staging live in week one, weekly updates, clean code your next developer won't hate. ◆ RELATED EXPERTISE Full Stack Developer: web developer, react developer, wordpress developer, mobile app developer React Next.js: nestjs, workbox.js, web developer, front end developer Front End Developer: web developer, full stack developer, react developer, react ◆ READY TO START ASAP

Throughout my career as a Front End developer, I've worked closely with designers, product managers, backend engineers, and business stakeholders to deliver products that are both technically solid and enjoyable to use. I believe a successful Front End developer should understand not only the code but also the goals behind the product. Technologies I work with As a Front End developer, my main stack includes: React Next.js TypeScript JavaScript React Native Angular Vue.js HTML5 CSS3 Tailwind CSS Material UI (MUI) SCSS Webpack Vite Node.js Over the years, I've helped companies hire a reliable Front End developer who can contribute quickly, improve existing codebases, and build new features with confidence. What I can help with As a Front End developer, I can help with: Building modern web applications from scratch Developing scalable React and Next.js applications Creating reusable component libraries Design system implementation Responsive and mobile-first development Performance optimization Server-Side Rendering (SSR) Progressive Web Apps (PWA) API integration Frontend architecture React Native mobile applications Refactoring legacy projects Bug fixing and maintenance Many clients choose me as a Front End developer because I can quickly understand business requirements and translate them into practical solutions. When companies need a Front End developer who can take ownership of a feature from planning to production, I can provide that support. I've worked as a Front End developer on both small startup projects and large-scale applications. My experience as a Front End developer allows me to adapt to different team structures, coding standards, and development processes. Although my primary role is a Front End developer, I also have experience with backend development. This broader perspective helps me become a more effective Front End developer because I understand how frontend systems interact with APIs, databases, and cloud infrastructure. I've worked with: PostgreSQL MongoDB MySQL Firebase Firestore Supabase AWS Node.js Python PHP This experience allows me to work effectively with backend teams and contribute as a Front End developer who understands the complete product lifecycle. How I work I believe a great Front End developer should focus on more than writing code. A Front End developer should understand user experience, accessibility, performance, maintainability, and business objectives. As a Front End developer, I value clear communication, ownership, and attention to detail. Every Front End developer should be able to balance technical excellence with practical business needs, and that's the approach I bring to every project. I've also contributed as a Front End developer in areas such as: Code reviews Technical planning Frontend architecture Git workflows CI/CD pipelines Agile development Team collaboration Mentoring junior developers Whether you need a Front End developer for a short-term project, a Front End developer for long-term collaboration, or a Front End developer to strengthen your current engineering team, I can help. My goal as a Front End developer is to build products that users enjoy using and that businesses can confidently grow over time. Companies often look for a Front End developer who can join an existing team and become productive quickly. Others need a Front End developer to help launch a new product or modernize an existing application. In both cases, I focus on delivering reliable, maintainable, and scalable solutions. If you're looking for a Front End developer with strong React expertise, modern frontend experience, and a practical approach to product development, I'd be happy to discuss your project. Best regards, Dmytro
