Next.js / React
Responsive websites, customer portals and working interfaces for booking, learning, documents and exchange services.
Andrey Mikhaylov · FOUNDER & DEVELOPER · BARCELONA
I build websitesand web applications.
My work starts with a conversation: who the product is for, what needs to happen in it and what already exists. I then plan how it fits together and develop the interface and backend. You can bring a new idea or an existing service that needs improvement.
Strapi & backend
CMS tailored to your team’s work, custom plugins, data models and access permissions. Node.js, NestJS, Fastify, PostgreSQL and SQLite.
APIs, AI & payment workflows
I connect external services through APIs and webhooks, linking orders and payment-provider events to product access. For AI consultants, I configure task-specific modes, retrieval from approved sources and knowledge-base updates.
Unreal Engine / C++
Alongside web work, I develop Unreal Engine and C++ game systems: interfaces, game states, progression and saves. My original games appear below.

Explore the projectThese projects began with different questions: how to welcome a guest, work through a document or understand a product price. In each one, I developed the interface and the systems that make it work.
