With 15 years of experience as a full stack developer I have actively shaped the technological backbone of businesses in different industries such as cyber security, online gaming and knowledge management.
On the frontend I have extensive experience in creating highly interactive web applications with React, Angular and PixiJS. On the backend my experience ranges from NodeJS/Express to Laravel to Wordpress to Golang. Additionally, I am fluent in git, and comfortable in Docker and AWS.
I believe that the work of a software engineer includes more than technology. A significant part of my job is asking the right questions: understanding the client and the goals of a project are essential to its success.
Both from a personal and professional perspective, I am very interested in the effects of emerging technologies — such as contact tracing apps — on society. I am currently enrolled in the masters programme Science-Technology-Society at the University of Vienna to put this interest into an academic context.

Robin Sulmann, Managing Director Begame (November, 2016)
1,5 years ago, we've hired Thomas for a short project of 3 months. Now 1,5 year later he's still one of the main pillars within our company who worked on, and finished the biggest project in our history as a lead developer.
Thomas is a real professional who can lead a big project to the next level. He's a highly experienced full stack developer who thinks commercially and in benefit for the company as well. Thomas is a real team player and will not avoid any good discussion how to move forward, because that's how he thinks, always going forward.
I will miss him as a person and as one of the best lead developers I have worked with.
In conclusion, I would highly recommend Thomas. He will be an extremely positive addition to your organization.

Harry van Mierloo, Founder at Ontwerper.com, UXMC (August, 2020)
It is a pleasure to work with Thomas. He is one the fastest frontend developers I've worked with, without sacrificing on quality. As a UX professional I regularly need to develop prototypes to evaluate my concepts, but Thomas' implementation speed often makes using prototype tools redundant, especially when designing data-heavy applications. His Javascript-skills are far above average, allowing him to deliver highly complicated frontend applications. He has a good sense for how his work relates to project & customer goals and he can act as a great example to junior developers, which is very convenient for team leads and product owners.

Kasper Mol, Tech Lead, Poki for developers at Poki (August, 2020)
I worked with Thomas both in a professional capacity for a longer period, as well as doing a 2-man web game project for a couple weeks in South-Afrika. Thomas is not just a very skilled full stack developer, but really enjoys the business and product side of what he's working on. That's what makes him a good developer, he'll always make sure that he's working on the right thing before he writes a line of code.

Olf Uineken, Co-Founder and CTO of Milkymap (August, 2020)
I hired Thomas as a senior developper for our front and backend development projects. His work is always accurate and his energy level is high. I really appreciate his feedback, always honest and to the point.
