Experience #

Senior Software Engineer (Platform & Infrastructure Engineering) #

SD Software-Design GmbH — Aug 2024 – Present | Remote (Freiburg, Germany)

Design and operate internal platform tooling and production infrastructure.

• Built a cross-team Go-based CLI tool to automate release workflows; reduced mobile release time from ~1 hour to a few minutes.
• Standardized infrastructure provisioning and deployment with Ansible; reduced service setup time to seconds and improved reproducibility.
• Designed and deployed a MariaDB Galera cluster for a SaaS with hundreds of paying organizations (ranging from small teams to 10k+ users); improved fault tolerance after prior DB failure and increased throughput via read/write splitting.
• Implement and operate CI/CD pipelines used by ~20 developers across ~10–15 projects; enabled self-service deployments and reduced time-to-production by ~90%.
• Consolidated server workloads, reducing infrastructure cost and operational overhead.
• Designed and built a Go-based CLI tool to scaffold standardized projects (Django + React, CI/CD, deployment integration); enforced adoption of a unified Python toolchain (uv, ruff, mypy) and reduced setup time and inconsistencies across teams and projects.
• Worked with product and engineering colleagues to identify bottlenecks and define requirements for internal tooling.
