Speed and Correctness Are Not Enemies.
Most companies treat quality as a tax on velocity. We believe the opposite: disciplined engineering practices are the only sustainable path to shipping fast, reliably, and without fear.
Like a specialist physician, Code Praxis diagnoses your codebase, prescribes the right practices, and works alongside your team to build lasting health — not just quick fixes.
Our Approach
Assess architecture, identify bottlenecks, and measure current quality metrics.
Immediate hotfixes for critical pain points without disrupting delivery.
Introduce TDD, XP, and trunk-based development as the new standard.
Refactor, build features, and establish CI/CD pipelines for long-term health.
Three Ways to Elevate Your Engineering
From hands-on development to team training and self-paced courses — structured to meet your organisation where it is.
Software Engineering
An external “Partner-in-Code” who provides architectural insurance and ships critical features. Specialising in FinTech, Automotive, Embedded Systems, and Backend architectures.
Workshops & Training
A quality injection for your team. Hands-on, in-house workshops in German or English that unify your engineers around XP practices and dramatically improve “Lead Time to Change”.
Online Courses
Pragmatic, production-ready mentoring for mid-level to senior developers. Learn TDD, system design, and modern CI/CD practices at your own pace — in German.
Dr. Stefan Trenkwalder
PhD in Robotics. 15+ years across FinTech, Automotive, and Embedded Systems. Advocate for TDD and Extreme Programming.
Stefan has built systems that run Vienna’s public transport announcements, developed safety-critical automotive software to ISO 26262 standards, and published 7 research papers on swarm robotics and real-time operating systems.
He brings the same rigour that safety-critical industries demand of every engagement — because software quality is not optional.

How We Work
Professionalism
Every engagement is treated with the same rigour as safety-critical software. No shortcuts. No technical debt left unaddressed.
Discipline
TDD, trunk-based development, and CI/CD are not optional extras — they are the foundation of every project we touch.
Reliability
Commitments are kept. Deadlines are met. Code ships. We measure our success by your team’s long-term velocity, not just the initial delivery.
Your Codebase Deserves a Diagnosis.
