About Cristian

I design and build complete systems, not isolated parts: I define the architecture, data flows, integrations, and overall behavior, and take them to production.
My specialty is systems that must run autonomously: with error handling, traceability, fault tolerance, and the ability to scale without rebuilding them from scratch.
How I can help you:
• Event- and state-based systems architecture
• Systems with AI agents coordinated on rules and objectives
• Real-time data platforms, dashboards, and automatic alerts
• APIs, backend, and tool integrations
• Process automation and document processing
• Sensitive information protection: encryption and access control
How I work: problem analysis → architecture → phased development with continuous validation → tested and documented delivery.
Stack: Python, FastAPI, SQL, AI model integration (OpenAI, Claude, Groq, local models), Linux, Docker, Git.
Proprietary systems in operation. Private demos available upon request.
