I will build a modern saas web app and desktop client
Sergey
About this gig
I am a modern Full-Stack Developer specializing in Greenfield projects (building from scratch). I use a cutting-edge tech stack (Next.js, Tailwind, Node, Supabase) and I am fully AI-augmented. By leveraging tools like Claude, I develop production-ready architectures significantly faster than traditional agencies, while maintaining strict human quality control over every line of code.
What I Build:
- Custom Web Apps & SaaS Dashboards: Fast, responsive, and beautiful interfaces.
- Automation Scripts: API integrations, data processing, and custom logic.
- Premium Desktop Apps (Tauri): Cross-platform apps (Windows/Mac) that are incredibly lightweight and fast (no bloated Electron apps here).
️ My Tech Stack:
- Frontend: React, Next.js, Vue, Astro, Tailwind CSS
- Backend: Node.js, Supabase, FastAPI
- Desktop: Rust (Tauri)
️ IMPORTANT: I specialize in building new projects. I do not fix bugs in old legacy code or customize WordPress/Wix sites.
Please send me a message before placing an order so we can discuss your vision and choose the perfect tech solution for your needs!

Solo full-stack developer from Ukraine, building production systems end-to-end — architecture, backend, frontend, deployment. I'm an AI-augmented developer: I use tools like Claude to move fast, but every architectural decision (data isolation, security, service boundaries) is mine, not blindly generated.
My main stack is React, Next.js, Node.js, TypeScript, and Rust for performance-critical parts. Recently shipped Mutuals, a real-time social platform with microservices architecture, live chat infrastructure, and a full admin/moderation system — deployed to production with Docker and CI/CD.

FAQ
Do you use AI to write the code?
Yes, I am an AI-augmented developer. I use advanced AI tools (like Claude) to rapidly prototype and generate boilerplate code. However, I act as the system architect: I design the logic, ensure security, and rigorously test everything. This means you get high-quality, custom software much faster.
What is Tauri and why is it in the Premium package?
Tauri is a modern framework for building desktop applications. Unlike older frameworks (like Electron) which use a lot of RAM and slow down computers, Tauri uses Rust to build apps that are incredibly fast, secure, and have a tiny file size.
Can you fix my existing PHP/WordPress/old React project?
No. To ensure the highest quality and delivery speed, I only take on "Greenfield" projects (building from scratch) or writing standalone scripts. I do not work with legacy code.
Can I see examples of your work?
Absolutely! My flagship portfolio piece is a complex, real-time social platform with a web and desktop client. Send me a message and I will gladly share the live link and screenshots of the architecture.
