• Structuring administrative processes in day-to-day business

By taking over operational back office tasks, management is noticeably relieved. Administrative processes run in a more structured, reliable, and efficient way, creating more time for clients, projects, and entrepreneurial decisions.

Zerobits is my vehicle for AI-powered automation and custom software development with a clear principle: AI solutions that reach production, not pilot stage. I design and build the systems myself - from first concept and architecture through implementation to deployment and operations.

My focus is on replacing repetitive, manual work with reliable automation and connecting disconnected tools and data sources into one dependable overall system.

Selected work:

• Design and implementation of LLM-based agent systems and RAG pipelines (Anthropic Claude, Mistral, MongoDB Atlas Vector Search + RAG)
• Workflow orchestration for long-running, fault-tolerant business processes using Temporal (temporal.io): saga patterns, event-driven architecture, retry and compensation logic, connecting third-party APIs and internal services into automated end-to-end processes
• Full stack product development: SaaS architecture on Kubernetes, TypeScript/React/NestJS, admin tooling with refine.dev and MUI
• AI-assisted development workflow as standard practice to deliver production software at a fraction of traditional timelines
• Full stack product development: multi-tenant SaaS architecture running on Kubernetes, backend with NestJS/Node.js and Python, frontend with TypeScript, React and Next.js, admin tooling with refine.dev and MUI, CI/CD with GitHub Actions

One of these projects is a product I own and operate - free of any NDA restrictions. I'm happy to demonstrate it end to end.
