🗣❝ Muhammad is really great with AWS services and knows how to optimize each so that it runs at peak performance while also minimizing costs. Highly recommended! ❞
⭐️⭐️⭐️⭐️⭐️
🗣❝ You would be silly not to hire Anas, he is fantastic at data visualizations and data transformation. ❞
🗣❝ Incredibly talented data architect, the results thus far have exceeded our expectations and we will continue to use Anas for our data projects. ❞
⭐️⭐️⭐️⭐️⭐️
🗣❝ The skills and expertise of Anas exceeded my expectations. The job was delivered ahead of schedule. He was enthusiastic and professional and went the extra mile to make sure the job was completed to our liking with the tech that we were already using. I enjoyed working with him and will be reaching out for any additional help in the future. I would definitely recommend Anas as an expert resource. ❞
⭐️⭐️⭐️⭐️⭐️
🗣❝ Muhammad was a great resource and did more than expected! I loved his communication skills and always kept me up to date. I would definitely rehire again. ❞
⭐️⭐️⭐️⭐️⭐️
🗣❝ Anas is simply the best person I have ever come across. Apart from being an exceptional tech genius, he is a man of utmost stature.
We blasted off with our startup, high on dreams and code. We were mere steps from the MVP. Then, pandemic crash. Team bailed, funding dried up. Me and my partner were stranded and dread gnawed at us. A hefty chunk of cash, Anas and his team's livelihood, hung in the balance, It felt like a betrayal.
We scheduled a meeting with Anas to let him know we were quitting and request to repay him gradually over a year, he heard us out. Then, something magical happened. A smile. "Forget it," he said, not a flicker of doubt in his voice. "The project matters. Let's make it happen!"
We were floored. This guy, owed a small fortune, just waved it away? Not only that, he offered to keep building, even pulled his team in to replace our vanished crew.
As he spoke, his passion was a spark that reignited us. He believed. In us. In our dream. In what he had developed so far.
That's the day Anas became our partner. Not just a contractor, but a brother in arms. Our success story owes its spark not to our own leap of faith, but from the guy who had every reason to walk away.
Thanks, Anas, for believing when we couldn't.❞
