🚀 Looking to secure your network infrastructures while automating your business processes?
I am a Network, Cloud & Automation Consultant (6+ years of experience — Alstom, Thales).
I support my clients on two complementary axes:
- Networks & Cloud: network migrations to cloud (AWS), advanced security (firewalls, VPN, ACL, IDS/IPS), high availability.
- Automation & AI: n8n / Power Automate workflows, API integrations, AI agents (chat, email, voice), reporting and monitoring.
🎯 What I bring you:
- Reliable and secure infrastructures, ready for the Cloud.
- Automations that save 5 to 30 hours/week and reduce errors.
- Clear documentation (HLD, LLD, runbooks, JSON export).
- Remote-first, pragmatic, and results-oriented collaboration.
📩 Contact me now to discuss your network or automation needs.
