I have over 15 years of experience in software development and training. Over those years I worked for many organizations, large and small.
Here is what some of my clients have to say about me:
I've been working with Tad on a range of software development and security trainings. The labs were creative and fun. I can definitely recommend him and I'll be happy to work with him again.
Maaike van Putten, (Virtual) Trainer and developer
In several weeks Tad and his team were able to understand our needs and deliver the first version of Lead Studio. Great development work!
Davy Guijt, Founder at Saleslift Studio
We hired Tad because of his experience in teaching software development using Elm. Thanks to his coaching we were able to develop a working prototype of a new product in just two weeks and are now generally more confident in our code.

Tadeusz is hands down one of the best JavaScript developers I have had a chance to work with. He's a smart person and has very strong analytical skills.
Wouter de Winter, CTO at Elanza
Tad understands technology well, listens carefully and communicates very clearly. Many times he helped us find pragmatic, simple and elegant solutions. We are glad to have him as a consultant.
