Wall of Fame
From mentoring 100+ engineers to building production MVPs.
Working with Adrian was great, he was an expert who could deliver the highest quality in the shortest amount of time, as well as lead, train and support other teams at the same time. I highly recommend working with Adrian and I hope we do work together again in the future.
Senior Product Manager @ ex-Sinch, ex-Bitrise
I work with Adrian as my mentor for three months, I can't thank him enough for how he was supportive, informative, and above all full of knowledge in the Front end industry. He is the kind of guy who tells you straight about your weakness and strength without hesitation. He always comes up with a personal plan that evaluates my progress and suggests the areas that need to be improved. I can proudly say with his help and guidance I am a confident front end developer and motivated every day to improve my skill sets, I genuinely recommend him to anyone who is looking for a mentor that he worth your time and investment.
