Full-stack development

Custom software for companies and professional practices.

I am an independent full-stack developer. I build web applications, management platforms and integrations for small and medium companies, craft businesses, professional studios and public bodies.

I work in a hands-on way and handle analysis, architecture, UX/UI, frontend, backend, integrations, deployment and maintenance directly. I can build a complete product or work on part of an existing system.

I add artificial intelligence features when the project calls for document processing, classification, data extraction, transcription, content preparation or automation.

Artificial intelligence

AI and automation

I integrate artificial intelligence into existing software and processes, or into the products I build.

The main applications I work on involve documents, search and information retrieval, classification, data extraction, transcription, content and automation connected to other systems.

When the result cannot be used automatically, I design the flow with review, confirmation or approval.

Case study

Operations and AI content
