DevOps Experts in Leipzig

As a project coordinator in development projects (consisting of software and hardware), I was responsible in an advisory capacity for creating recommendations and organizational framework conditions in the areas of reporting, project scheduling, progress tracking, resource allocation, and presentation of results.

• Technology stack: Teams, Azure DevOps, Android
• Keywords: software, hardware, AI, MDM, Kanban, requirements specification, functional specification, SaaS, ergonomics, health, medical device

Goal: Coach a new agile team to implement and deliver the MVP of an AI-powered digital insurance service.

• Kicked off and coached a new cross-functional agile team as Scrum Master.
• Introduced a new Product Owner to the role with coaching, close collaboration and support with daily operations and backlog management in Jira.

• Facilitated and supported planning and decision-making activities regarding the MVP delivery (roadmap creation, release planning, test management, translation of user feedback into product decisions)
• Continuously improved processes across multiple agile teams, closely collaborating with other Scrum Masters and cross-team roles (leads, architect, test manager).
• Designed and facilitated in-person and remote workshops as needed across multiple teams (agile practices, problem solving, process improvement, AI powered product development).

• Built an internal AI recruitment assistant (Python, LangChain, Claude API) and deployed it into the team's Greenhouse workflow: automated candidate screening, structured interview-feedback extraction from transcriptions, and comms across high-volume DACH/EMEA GTM pipelines. Scoped the need with TA/GTM leadership, shipped the tool, and drove day-to-day adoption, the same loop a forward-deployed engineer runs at a customer site.
• Led ATS migration from Personio to Greenhouse across the whole team: data model, migration, and team adoption.
• Ran discovery-style intake calls translating vague requests ("we need someone senior for Italy") into structured requirements, the muscle a forward-deployed engineer uses to scope a customer deployment. 80%+ offer acceptance, ~120% of quarterly targets. Discovery and delivery in EN, DE, ES, FR.
