## Summary

Software Engineer, three years at SFR on the real-time digital twin of the network: data ingestion, graph, real-time web interface and AI agents for root cause analysis, built with the network teams that use them. I ship and run what I build, from the data to the screen. On the side, a homelab and personal projects, from electronics to the web.

## Experience

### Software Engineer, SFR (Full-time), Sept 2025 - present

Real-time digital twin of the network: 100k+ devices, dozens of users.

- **Ingestion of SNMP metrics** (Zabbix via Kafka), network discovery (S3) and syslog into ClickHouse, plus the transformations feeding the graph: a log is visible in the interface in **under a minute** (Vector, Go)
- **Neo4j graph of the network**, Graph Data Science algorithms (max flow) flagging isolated routers
- **Real-time web application** on the state of the network, refreshed over SSE (TypeScript, TanStack Start)
- **AI agents for root cause analysis** in natural language: three MCP servers (Neo4j, ClickHouse, NetBox) and a custom RAG tool (Deep Agents)
- Started the AI agent work alone, then **mentored an intern** on it
- **Seven services in production**, run autonomously from provisioning to upgrades, plus one OpenShift deployment

### Software Engineer, SFR (Apprenticeship), Sept 2023 - Sept 2025

Internal tools for the network engineering teams, start of the digital twin project.

- **Network visualization application** with Neo4j and Next.js, to analyze and optimize the infrastructure
- **Router configuration tool** with Vue.js and Django, plus Python automation scripts cutting deployment time and manual errors

### Web & Mobile Developer, Kynova (Apprenticeship), Jun 2022 - Jun 2023

Websites and mobile apps for the agency's clients.

- [Aroma](https://bruno.seilliebert.dev/work/aroma.md) (Next.js, PocketBase, PWA): Check your university schedule on mobile, where ADE is barely usable on a phone.
- [Homelab](https://bruno.seilliebert.dev/work/homelab.md) (Kubernetes, Talos, Cilium, Flux): A self-hosted Kubernetes cluster running my apps, my personal services and the connected home.
