🚀 Senior React & Next.js Developer | Forward Deployed Engineer | Web & Mobile 📱 React Native, Capacitor, iOS & Android 🤖 AI Development with Lovable, Replit, Bolt, Claude, GPT & Cursor ⚡ 7+ years of professional experience I’m a Senior Software Engineer and Forward Deployed Engineer with 7+ years of experience building web and mobile applications. Most of my work involves taking an idea, an existing application, or a business problem and turning it into something that actually works in production. I’m comfortable working from detailed requirements, rough ideas, designs, or an existing codebase. I’ve worked with startups, businesses, and individual clients where I’ve been responsible for everything from understanding the requirements and choosing the right approach to development, integrations, testing, and deployment. A few things about my background: • Top Rated Developer on Upwork • 50+ completed projects • $40K+ in Upwork earnings • 2,200+ hours worked on Upwork • 7+ years of professional development experience • Strong experience with React, Next.js, React Native and TypeScript # Forward Deployed Engineer I also work as a Forward Deployed Engineer, so I’m comfortable getting involved beyond just writing code. I can work directly with clients or product teams, understand the actual problem behind a feature, figure out the technical approach, work with existing systems and APIs, and take the solution through development and deployment. This is useful when the requirements aren’t always perfectly defined and you need someone who can understand the problem and figure out the best way to solve it. # AI-assisted development AI is now a big part of my development workflow. I regularly use **Claude, ChatGPT/GPT, Cursor, Lovable, Bolt and Replit** for prototyping, coding, debugging, refactoring, documentation and exploring different approaches. I also have experience with **prompt engineering and AI-assisted “vibe coding”**, especially when building MVPs and turning ideas into working products quickly. I don’t simply generate code and ship it. I use AI to speed up the parts of development where it makes sense, while I handle the architecture, technical decisions, code review, debugging and final implementation. # My main skills Frontend: React.js, Next.js, TypeScript, JavaScript, Tailwind CSS, Bootstrap, Vue.js Backend: Node.js, Express.js, GraphQL, MongoDB, Supabase, Firebase Mobile: React Native, Capacitor, iOS & Android AI & Development Tools: Lovable, Bolt, Replit, Claude, ChatGPT/GPT, Cursor, Prompt Engineering Other: Electron.js, REST APIs, third-party integrations, Git, GitHub, GitLab, Jest, Postman, Swagger # Projects I usually work on • SaaS products and MVPs • AI-powered applications • E-commerce and marketplaces • Dashboards and admin panels • API and third-party integrations • Real-time web applications • React Native mobile apps • Converting existing web applications into mobile apps • Fixing, improving and extending existing applications I care about writing code that is easy to maintain and making sure the final product works properly, not just getting a feature to run once. If you already have a project, an existing application, or even just an idea you want to discuss, feel free to send me the details. I can help you figure out the best way to build it.
