Zurich, Switzerland
Senior Software Engineer& Technical Lead
I build reliable production software and lead engineering teams, staying hands-on across frontend, backend, data, deployment, and observability.
About
My professional background is in healthcare and enterprise software, where I have built production systems that depend on correctness, reliability, and clear operational workflows. I currently lead a six-person engineering team while staying hands-on across frontend, backend, data, deployment, and production concerns.
My work combines technical direction with implementation: clarifying requirements, guiding architecture, reviewing code, mentoring engineers, and improving performance and operability. I value pragmatic solutions that teams can understand, evolve, and maintain under production pressure.
Experience
My background spans technical leadership, reliable data-heavy systems, operator-facing workflows, integrations, observability, deployment, and pragmatic delivery across production software environments.
I currently lead a six-person software engineering team at CISTEC building healthcare software, combining technical direction and team leadership with hands-on implementation across React, TypeScript, Java, Oracle, and production delivery workflows.
The work centers on reliable data flows, understandable failure states, operability, observability, careful change management, and software that teams can maintain under production pressure.
- Lead planning and day-to-day delivery for a six-person engineering team through architecture guidance, code review, mentoring, and implementation support.
- Collaborate with product owners and stakeholders to clarify requirements, evaluate trade-offs, and turn complex healthcare workflows into usable software.
- Set technical direction for performance-sensitive, maintainable React, TypeScript, Java, and Oracle systems and support their delivery through Kubernetes/Argo CD deployment workflows.
- Support production readiness through release processes, CI/CD, monitoring, and pragmatic debugging across frontend, backend, and data workflows.
Senior Full-Stack Developer
Built and improved data-heavy production software across frontend, backend, database, release, and operational concerns before moving into the current leadership role.
- Reworked a performance-critical TypeScript JSON parsing library, making benchmarked parsing 25x faster and reducing user-facing load times by around 80%.
- Delivered healthcare workflows with React, TypeScript, Java, Node.js, and Oracle where correctness, traceability, privacy, and maintainability were critical.
- Improved production readiness through refactoring, clearer interfaces, testing, structured logging, release support, and pragmatic technical cleanup.
Freelance Full-Stack Developer
Delivered customer portals and business applications across frontend, backend, APIs, deployment workflows, and stakeholder requirements.
- Worked with React, Node.js, Java, Ruby, C#/.NET Core, ASP.NET, REST APIs and CI/CD.
- Handled requirements analysis, implementation, UI/UX detail and pragmatic delivery decisions.
Software Engineer
Built software across test automation, enterprise systems, ERP integrations, building automation, and web applications, forming a broad engineering base beyond one technology stack.
- Previous roles include Tricentis, Vienna University of Technology, More Dimensions and VBV Pension Fund.
- Worked across test automation tooling, cultural institution software, building automation systems and enterprise integrations.
Work
Selected Work
Selected work across performance, reliability, observability, and product engineering. Company work is summarized without proprietary details.
Engineering impact
25x parser speedup, around 80% faster loads
Performance-critical JSON parser rewrite
Reworked a performance-critical TypeScript JSON parsing library, making benchmarked parsing 25x faster and reducing real user-facing load times in data-heavy healthcare workflows by around 80% through lower algorithmic complexity and hash map-based lookups.
More resilient business-critical data processing
Recurring healthcare data workflow reliability
Improved reliability for a recurring healthcare data-processing workflow through batching, caching, observability, and fault isolation, strengthening business-critical downstream processes.
Safer debugging in a privacy-sensitive environment
Production monitoring and privacy-aware logging
Introduced Grafana- and Loki-based production monitoring and improved structured application logging, using explicitly approved fields to support safer debugging in a privacy-sensitive healthcare environment.
Additional technical range
Building monitoring gateway and research paper
Built a Java-based Raspberry Pi data gateway for university research, integrating wireless sensor streams, local Derby persistence during connection loss, and reliable forwarding to a remote monitoring service. I validated it with more than 100,000 measurements, first-authored the resulting conference paper, and presented the work at ECPPM 2014 in Vienna.
Robotics platform projects
In my spare time, I explore robotics platform engineering through public prototypes covering fleet operations, telemetry health, reconnect recovery, ROS 2, and simulation. This work is separate from my professional production experience.
Crowdsourced usability testing engine prototype
Built a 2nd-place company hackathon prototype for a usability-testing engine that sent microtasks to Amazon Mechanical Turk, exploring how crowd workflows could produce fast product feedback.
Published Android game and Steam Greenlight project
Built 3D physics-based games involving real-time simulation, collision detection, and spatial interaction systems, including a released Android game that reached over 2,000 installs and a PC game accepted through Steam Greenlight community voting.
Education
Formal education in software engineering, computer science, and information technology.
Bachelor's studies in information and communication systems, with practical work across software engineering, ICT systems, networks, and services.
Technical secondary education in information technology, providing an early practical foundation in software and IT systems.
Contact
I am always interested in thoughtful conversations about senior software engineering, technical leadership, full-stack development, and reliable production systems.
