I am Kevin Bataille, a network and telecoms engineer originally from La Réunion, currently based in Paris. Passionate about critical infrastructure, transmission technologies, and innovation, I use this space to share my reflections, projects, and discoveries.
In my professional background, you will find:
- Design and maintenance of fiber optic, SDH/WDM, and IP/MPLS networks.
- Migration of legacy systems to modern architectures.
- Software development and system administration (GNU/Linux, Docker, Python, etc.).
- Open source contributions.
Areas of Expertise
1. Fiber Optic Networks and Transmission
I began my career in fiber optic infrastructure, where I was responsible for the design and maintenance of optical networks.

Historically, my role involved product selection (jumpers, splice protection boxes, optical distribution frames, racks, etc.), drafting technical engineering rules, and creating associated documentation. I was responsible for producing the necessary components for design offices to create installation and deployment documents. This also involved public tendering and procurement processes.
View details on TDM and WDM systems
Currently, I work extensively on TDM (Time Division Multiplexing) networks. My employer makes heavy use of Alcatel equipment (for PDH) and Sagemcom (for SDH). I am responsible for maintaining these systems while also researching alternative solutions to phase out these aging technologies.
I also work on transmission networks, specifically using ADVA (now Adtran) equipment and their FSP and CloudConnect product lines.

I design WDM networks and maintain the long-haul WDM network that carries critical SDH and IP services. I handle the engineering, production of realization-phase documentation, and oversee deployments until the commissioning of links ranging from 1 Gbit/s to N x 100 Gbit/s, with or without OTN cross-connects.
2. IP Networks
In addition to fiber and transport layers, I practice IP networking for both personal and professional projects. I successfully launched a project to develop a small-scale Internet Service Provider (ISP) in La Réunion. We offer Internet services, landline telephony (with regional numbering), and IPTV.
I work daily with the following routing protocols:
- IPv4 & IPv6
- OSPF & BGP
- MPLS (with LDP or RSVP)
- EVPN & VXLAN
- Multicast (IGMP and PIM-SM)
Vendor Proficiency
| Manufacturer | Technologies | Use Case |
|---|---|---|
| FS.com | Switches/Routers | Enterprise LAN/WAN networks |
| MikroTik | IPv4/IPv6 Routing, OSPF, BGP, Multicast | ISP and Enterprise networks |
| Cisco/Juniper/Nokia/HPE | MPLS (LDP/RSVP), EVPN, VXLAN | Critical and industrial networks |
| Terra Electronics | DVB | Reception and broadcasting of SD/HD video streams |
3. System Administration and Development
GNU/Linux Systems
In my spare time, I develop personal projects to automate repetitive tasks, learn new technologies, or simply for “fun or profit.” I frequently work with Ubuntu, Debian, and Fedora distributions.
Technical Stack Details
I install and configure technical stacks including:
- Web Server: NGINX (advanced configuration, reverse proxy)
- Databases: MariaDB (optimization, replication)
- Containerization: Docker (orchestration via Docker Compose)
- Dynamic Routing: Bird and FRR
Development
| Language/Framework | Usage | Project Examples |
|---|---|---|
| Python | Automation, data analysis | Telephony management and monitoring tools |
| PHP | Backend (CakePHP, Laravel) | Dynamic websites and custom CMS |
| Ruby on Rails | Backend and rapid prototyping | Business apps and telecom operator portals |
| JavaScript/Node.js | Frontend (VueJS) or Backend (APIs) | Dashboards |
| SQL | Database Management | Migration and backups |
Voice over IP (VoIP)
I implement telephony solutions based on:
- Kamailio: SIP server for IP telephony.
- Asterisk and FreeSwitch: Open-source PBX.
- Grandstream: Gateways and IPBX.
