I am a fullstack web developer with 4+ years of experience building web applications for startups, agencies, and growing businesses.
My main work is around React, Next.js, Node.js, TypeScript, APIs, databases, dashboards, e-commerce platforms, admin panels, SaaS tools, fintech products, and production deployments.
I can help you build a new application from scratch, add features to an existing product, fix bugs, clean up messy code, improve performance, or deploy your app properly.
**What I Can Help With**
- Custom web applications using React, Next.js, Node.js, TypeScript, and Tailwind CSS
- SaaS dashboards, admin panels, analytics tools, reporting systems, and internal tools
- E-commerce features like product pages, carts, checkout flows, Stripe payments, subscriptions, and admin tools
- Backend APIs using Express.js, NestJS, REST APIs, authentication, JWT, OAuth, RBAC, middleware, and webhooks
- Database work with PostgreSQL, MongoDB, MySQL, Supabase, Firebase, Prisma, TypeORM, Mongoose, SQL, migrations, indexing, and schema design
- AI features using OpenAI API, Claude API, Anthropic API, LLM integrations, AI chatbots, AI assistants, AI agents, RAG, vector search, embeddings, and workflow automation
- Deployment with Vercel, DigitalOcean, AWS EC2, Linux, Ubuntu, Nginx, PM2, Docker, Docker Compose, GitHub Actions, SSL setup, environment variables, and CI/CD
**Why Work With Me**
I write practical, maintainable code that is easy to understand and build on. I can handle both frontend and backend work, so I’m comfortable taking a feature from idea to production.
I also understand product needs, not just isolated coding tasks. I care about performance, usability, clean architecture, clear communication, and regular updates.
I am comfortable working with founders, agencies, designers, and development teams. I also use tools like Claude Code, Cursor, and AI coding agents when they help move faster, while still reviewing the work carefully myself.

Top-rated on Upwork (1+ year). 100% Job Success. $10,000+ earned, 10+ projects, 900+ hours, working on Upwork since 2019.
I'm a Senior React & Next.js engineer who SaaS founders and product teams hire when they need to build, scale, or improve production applications. Whether it's a complex dashboard, an AI-powered platform, or a frontend that has become difficult to maintain, I help teams deliver clean, scalable, and production-ready software.
I've worked with startups and established companies across the US, Europe, and the Middle East, building SaaS products, AI platforms, internal business tools, restaurant management systems, and marketing websites used by real customers.
► Track Record
Dishplayed (Netherlands) — Worked as a Senior Full-Stack Developer on a restaurant SaaS platform, building complex dashboards, responsive interfaces, backend APIs, and scalable architecture using React, Next.js, NestJS, MongoDB, and AWS.
Mirra (USA) — Joined the team to help launch the MVP, building production-ready features with Next.js, TypeScript, Supabase, PostgreSQL, and modern frontend architecture.
ILA26 — Developed production-ready React and Next.js features from pixel-perfect Figma designs, improving frontend architecture, performance, and the overall user experience of a live web platform.
► What I Deliver
• End-to-end frontend development with React & Next.js
• Production-ready SaaS dashboards built for real-world usage
• Pixel-perfect implementation from Figma with attention to UX details
• AI product interfaces and third-party API integrations
• Full-stack capability using Node.js, NestJS, Express.js, PostgreSQL, and MongoDB
• Performance optimization, responsive design, and maintainable frontend architecture
► Special Focus: AI-Powered SaaS Products
I've worked on AI-powered products where the challenge wasn't just integrating AI APIs—it was building intuitive user experiences around them. My focus is creating interfaces that feel natural, responsive, and trustworthy while keeping the frontend scalable and maintainable as products evolve.
► Whom I Work With
I primarily work with SaaS startups, product companies, and growing businesses that need an experienced frontend engineer to take ownership of the product, collaborate closely with designers and backend developers, and deliver production-quality software. Most of my clients are based in the United States, Europe, and the Middle East.
► Technologies
Frontend: React.js, Next.js, TypeScript, JavaScript, React Native, Redux Toolkit, Tailwind CSS, Material UI, Framer Motion
Backend: Node.js, NestJS, Express.js, REST APIs
Database & Cloud: PostgreSQL, MongoDB, Supabase, AWS, LLMs
► How This Works
I work directly with founders and engineering teams, communicate clearly, and focus on shipping high-quality features quickly without sacrificing maintainability. You'll see real progress within the first few days—not weeks of unnecessary discovery or overengineering.
If you're building a SaaS platform, AI product, dashboard, or complex web application and need someone who can take ownership of the frontend and deliver production-ready code, I'd be happy to discuss your project.
