I build software across full-stack product development, applied AI, automation and systems integration. My primary stack includes TypeScript, React/Next.js, Python, APIs, PostgreSQL and modern automation tools.
My recent work spans conversational AI, RAG, AI agents, CRM and data integrations, analytics pipelines and ERP-related automation. My earlier background in mechatronics, automotive electronics and industrial systems gives me a systems-oriented approach: understand the process, identify the constraints, build the solution and integrate it into real operations.

How I build
AI-assisted development is part of my normal engineering workflow. I use coding agents and AI tools for implementation, investigation, refactoring, debugging, testing and iteration.
I remain responsible for requirements, technical decisions, review, validation, integrations, security and final behavior.
The emphasis is reliable software and efficient delivery—not the number of tools used or lines written manually.
