I've had the pleasure of working with Yousef on a number of different projects including a digital donation/communication solution for places of worship, which uses geofence technology, as well as an online B2B Network and business directory.

Aside from being hands down the best software developer I've worked with, I've always admired how Yousef is able to utilise a huge library of products, resources and deep tech solutions to create the path of least resistance in solving complex problems.

As well as this, in's rare to find someone who is both passionate about making an impact, without any financial motivation, but also able to approach this with a highly logical and systematic mindset, ensuring his skills are utilised in the most effective way.

Yousef has been a pleasure to work with, bringing great energy and humour, and I look forward to benefitting from his expertise and passion for many years to come!

Having worked alongside Yousef for almost three years, I can wholeheartedly vouch for his exceptional qualities. As our CTO, he was not only a master at recognizing promising ideas and embracing new technologies, but funny enough he has a term (wikipedia link included) for every situation.

In the tech realm, Yousef is unparalleled. His foresight and step-by-step approach to implementation always keep him ahead of project requirements. His contributions consistently go beyond expectations, making him an invaluable asset to any team.

In short, Yousef is the leader and tech wizard every team needs.

I have worked with Yousef on Sawa (a digital donation and tech platform for masjids in the UK) for nearly 2 years. I don't know what more I can say than to tell you that I hit the jackpot with him as a cofounder. He is uniquely talented in everything tech and also an incredible mind to brainstorm and work through real problems with. His commitment to our project has made it possible for us to provide an innovative solution to a difficult problem and I am very proud that he is a part of our team and to call him a friend.

Yousef is that mentor everyone wants who's patient, open minded, kind and clever. Yousef was attentive and asked the right questions to get a sense of what I needed out of the mentorship session I'd with him. He took his time to go through my CV and pointed out things I could do to improve the result I was already getting. After making the changes, Yousef asked that I send it to him and he still took another look at it and make some adjustments. Yousef shared with me a great number of resources and he introduced me to websites which will aid me in my job search and increase my chances of getting interviews. He carefully walked me through how I can write a good cover letter. I'd highly recommend Yousef to anyone.

Yousef was my mentor around a year and a half ago when I was on route to completing my degree in cybersecurity. I wanted to connect with others from an ethnic minority background who are also in cyber but was hesitant, lacked experience and wasn't sure how to go about it.

After initiating this idea to Yousef, he helped me create a channel which grew from 7 members to around 70+ people who are all actively helping one another in their areas.

Thank you Yousef for helping me have this idea landed, giving me the courage to publicise it and helping our community connect with one another more easily!

Yousef has become a great friend of mine and has supported me immensely, both professionally and personally. Despite being outside of the tech arena myself, it is striking how his skills and insights are still applicable to my line of work. Yousef has helped me developed ideas in the early stages of my enterpreneurial journey, and I'm sure he will continue to be a great advisor. On top of tech, Yousef is knowledgeable in bridging the gap between academic humanities and the real world. Even if you don't work in tech, I believe Yousef's broader knowledge and expertise can help one to acheive their goals, whatever they may be.

I have known Yousef for several years now, since our days at high school, and have been in touch ever since.

Yousef is an experienced tech entrepreneur who deeply understands his work and gets things done efficiently, thoroughly, and correctly in accordance with best practices. Drawing from his vast work and volunteering experience as well as his large skillset, Yousef has an immediate grasp of the scope of any task, and is quick to identify potential complications so they can be promptly addressed.

Yousef is a natural mentor who is generous with his time and expertise, and can be relied on by his colleagues and friends to provide valuable insight and guidance. I recommend Yousef to anyone who values a principled and honest team player.

I came across Amar's path through an interview in krew.live where he used to be the CTO. He is someone with immense knowledge and empathy for people around him. He is a phd, which affirms for his knowledge. I also liked how helpful he is. He used to help on certain things if I asked through mail even after I left Krew. He is a great mentor for sure alongside being a great person.
