You will get AI-powered web app or chat interface using Next.js and OpenAI API
Project details
I build production-ready AI web applications with clean architecture and scalable design using modern technologies like React and Next.js.
Unlike basic AI demos, my focus is on real-world usability, performance, and extensibility — so your application can evolve into a full product.

About Pavlo
Senior Fullstack Engineer | React, Next.js, SaaS, Fintech, AI Apps
Kyiv, Ukraine - 5:28 am local time
I’m a Senior Fullstack Engineer with 10+ years of experience building SaaS platforms, fintech systems, payment solutions, and complex multi-application products.
I’ve worked on high-load systems and product ecosystems with 10+ applications, focusing on performance, scalability, and maintainability.
Key results:
– Improved platform performance by 2.2x
– Increased development speed by 40%
– Improved developer efficiency by 30% (including AI-assisted workflows)
– Built shared architecture, internal SDKs, and reusable systems across multiple applications
🚀 What I can help you with
Fullstack development
– React, Next.js, TypeScript
– Node.js (Nest.js), Go backend

🧠 How I work
I focus on building systems that are:
– scalable and maintainable
– easy to extend and support
– aligned with business goals
I don’t just write code — I help structure products so they can grow without becoming technical debt.
I’m comfortable working across the full product lifecycle:
– idea validation
– architecture design
– development
– optimization and scaling
🤝 Collaboration
If needed, I collaborate with a UI/UX designer to deliver full product solutions — from idea and design to development and production.
This allows us to cover the full process while keeping the flexibility and speed of a small team.
