Summary

Senior software engineer (7+ years) building and operating large-scale networked systems: Go-based Kubernetes operators and GitOps automation for Swisscom's 5G Core, a multi-cluster DNS platform with millisecond query latencies, and Python cloud services at Semtech serving millions of IoT devices. Co-founder and technical lead of Azeff, an agentic AI platform for the live-music industry, built end-to-end in Python. Comfortable across the full stack, from embedded hardware and network protocols to cluster-scale automation, with a record of building maintainable, long-lived tools and contributing to open source. Speaker at KubeCon, Open Source Summit, and ContainerDays. Native French and German, fluent English.

Work Experience

Zürich, Switzerland

• Kubernetes-based network automation: designed and implemented Kubernetes resource models and Go-based operators that automate Swisscom's 5G Core networking stack (BGP peering, routing and prefix management, VPN provisioning, and CNF configuration), reducing deployment time from weeks to minutes.
• Multi-cluster DNS: built a cloud-native, on-prem multi-cluster DNS solution, removing external dependencies and reducing query latencies to milliseconds.
• Security architect: created threat models for network automation components, hardened Kubernetes clusters and enforced strict tenant isolation.
• Open source: contribute Swisscom's cloud-native telco tooling back to the community at github.com/swisscom/cloud-native-telco.
• AI ambassador: core developer and designer of Swisscom's company-wide central MCP (Model Context Protocol) proxy service.
• Knowledge sharing: lead Swisscom's Kubernetes Center of Practice, running workshops and talks that upskill engineers company-wide and create cross-team synergies.

Berlin, Germany (remote)

• Agentic AI platform: co-founded Azeff, an agentic AI booking platform for the live-music industry (touring and artist management), built end-to-end in Python. Lead architecture and technical delivery across the full stack (Pydantic AI, Temporal, PostgreSQL, Kubernetes).
• Agent and workflow engineering: built LLM agent workflows with durable execution on Temporal and event-driven venue-outreach automation.
• Knowledge and ML: designed a multi-tenant, four-layer knowledge architecture combining PostgreSQL, vector search, and graph memory. Developed sellout-probability and ticket-price prediction models.

Zürich, Switzerland

• LoRa Cloud Locator on AWS: core Python developer from initial concept to general availability, including monitoring, troubleshooting, and release upgrades.
• Sensing-as-a-Service platform: infrastructure lead and core developer of a large-scale IoT platform for healthcare (Python services on AWS), connecting millions of devices via sensors and gateways.
• DevOps and automation: operated high-availability production Kubernetes clusters with multiple deployments and SLA-driven monitoring.

Zürich, Switzerland

• LoRa Cloud geolocation and modem services: principal developer of the ephemeris collection service (Python), delivering satellite position data through redundant pipelines. Deployed in every AWS region and still in production today.
• Global content delivery: designed and deployed a worldwide CDN tuned for low latencies using AWS.
• DevOps and automation: migrated from VM-based infrastructure to Kubernetes with full IaC, CI/CD, and on-prem containerized solutions.
• Research: investigated satellite orbit parameter estimation and fusion.

5G heterogeneous network architectures for IoT, Ecublens, Switzerland

• Hardware: designed and assembled a prototype with a custom PCB using STM32 and multiple add-on modules with modems from Quectel and Semtech.
• Software: implemented the full stack from embedded control and precise power and latency measurements to a cloud back end using Azure IoT Hub.
• Research: built a network orchestrator for a heterogeneous protocol suite. Adapted the LoRa modem stack to enable device-to-device (D2D) communication integrated with LTE Cat-M1, NB-IoT, and LoRaWAN.
• Result: grade 5.75 out of 6 (Swiss scale).

Ennos AG, Junior Enterprise EPFL, SIXA GmbH, Zimmermann AG

• Various software design and development projects: React front ends, a Chrome extension, an Excel parser, a website crawler, automation tools, and AWS-based back ends.
