Martin Trenker

Consultant, Web Developer

About me

My passion for web development started in the 90s when free web hosting became popular. I became active in the community, helping aspiring developers with HTML, CSS, PHP, MySQL, and JS.

Today, I love building things in the cloud and creating user-oriented, interactive experiences while spreading awareness for clean code and authentic agile practices.

Clean and Agile

I am privileged to have worked with many bright minds over the years and want to share my experience with my clients. With a better understanding of quality management, agile best practices, and a human-centric approach, we can build better products and create a healthier work environment for everyone.

Learner and Mentor

Every project has its unique challenges. I love analyzing and understanding them from a cross-functional perspective to expand my horizon and, on the way, pass some of it to aspiring and seasoned developers alike.

Automation

As an automation nerd, I can help identify and implement automation of repetitive tasks that waste time and energy teams could use for new features instead.
