About Sergei
AI & SaaS Apps Developer | Full-Stack | Web3 & AI Integrations
Varna, Bulgaria - 12:00 pm local time
My focus is practical implementation: turning complex concepts into working software with scalable architecture, clean interfaces, and reliable backend infrastructure.
I work across the full stack - designing and building both frontend and backend - and integrating AI models, automation, and blockchain functionality directly into real products.
Typical projects I work on include:
• AI-powered web applications
• SaaS platforms and startup MVPs
• AI agents, chatbots, and automation systems
• Full-stack web development (frontend + backend)
• Blockchain and Web3 integrations
• Crypto products, tokens, and on-chain tools
• API integrations and backend architecture
• Rapid prototyping and product launches
I can take a project from concept to deployment - including architecture, development, and integration of modern technologies such as AI models, agent systems, and blockchain infrastructure.
Technologies commonly used in my work:
• JavaScript / TypeScript
• Node.js backend systems
• Modern web frontends
• AI APIs and agent frameworks
• Web3 / blockchain integrations
• Cloud deployment and production infrastructure
I work with startups, founders, and teams who want to build real products - not just prototypes.
If you need to turn an idea into a working AI or SaaS product, I can help deliver it.
