I'm Frances Ruganyumisa (he/him) — a networking and security engineer focused on microservices, network automation, and IoT security research. I design and build secure, resilient systems and automation to reduce toil and speed up safe deployments.
- 🔭 Currently building microservices and automation tooling for network and security teams
- 🌱 Researching IoT device security, firmware hardening, and secure OTA processes
- 👯 Open to collaborate on SDN, network automation, and security automation projects
- ⚡ Fun fact: I enjoy pairing on hard problems and learning new attack/defense techniques
- Microservices architecture & secure API design
- Network automation & orchestration (Ansible, Terraform, Nornir, Netmiko)
- Security automation: detection, triage and automated response
- IoT security: device analysis, firmware protections, threat modeling
- SDN, BGP, routing fundamentals, and service mesh concepts
- Containerization & orchestration (Docker, Kubernetes)
- Languages: Python, Bash (familiar with Go and JavaScript)
- Automation & infra: Ansible, Terraform, Nornir, Netmiko, GitHub Actions
- Cloud & containers: Docker, Kubernetes, Helm, Prometheus, Grafana
- Security: vulnerability assessment, threat modeling, detection engineering
- Networking: routing & switching, BGP, SDN controllers, network observability
Below are example project templates and the kinds of repositories I build or contribute to.
-
Network Automation Framework — a collection of playbooks and scripts to provision, validate, and test network devices at scale. (
network-automation) -
Security Automation Playbooks — automated detection -> triage -> response workflows that integrate SIEM/EDR alerts with orchestration tooling. (
security-playbooks) -
Secure Microservices Reference — sample microservices demonstrating secure defaults (authentication, mTLS, rate limiting, logging). (
secure-microservices-sample) -
IoT Analysis Toolkit — tools to analyze firmware, identify insecure configurations, and prototype mitigations. (
iot-security-tools) -
SDN Proofs-of-Concept — small demos showing SDN controller integrations, programmability, and service chaining. (
sdn-poc)
- I aim for reproducible automation: infra-as-code, idempotent playbooks, and unit-tested scripts.
- I document threat models, test cases, and expected telemetry for all security projects.
- I prefer small, iterative PRs with clear test plans and CI checks.
If you'd like to collaborate, open an issue, or send a PR to any repo, I review and respond to collaboration requests.
