Cristian Nita

I am a backend and automation engineer with 8 years of international experience, focused on Node.js and data‑centric systems: pipelines, migrations, and integrations for SaaS and internal tools. As a remote contractor, I design and build custom Node.js services together with n8n workflows and LLM agents (chatbots, RAG, document extraction), often delivering production‑ready automation in a matter of days.

My work centers on system integration and data work: legacy systems migrations, data pipelines (ETL/ELT), and automations that connect CRMs, ERPs, accounting tools, and internal platforms using n8n, LLM wrappers, RAG systems, and CLI/MCP tools. The largest system I’ve handled was a telecom migration of a 20 years old database used by tens of live producer & consumer systems with zero downtime, which focus on data integrity, availability, security, and robustness.

Across roles, I’ve often sat between business and engineering, leading small remote teams and now working as a freelancer to audit internal systems, co-design target architectures, migrate to newer or custom platforms where needed, integrate tools, and automate repetitive work for clients.
