Aamir Butt has been an incredible mentor throughout my coding journey. He stayed up late nights helping me solve problems and guiding me step by step. Whenever I called, he made the time to answer and went the extra mile to ensure I understood everything.
Amir is an exceptional, super smart firmware engineer that was able to work and deliver on our complex project. His expertise in app development is impressive, responsive and hard working. Will continue to work with him and recommend him to everyone.
He developed custom ESP32 software for me that runs smoothly — controlling music playback and displaying animations on a round LCD. Communication was clear, updates were consistent, and he went above and beyond to make sure everything worked perfectly.
Amir. He is a charming man! Understands and learns the professional need! Humane and tolerant! Highly recommend working with him.
Aamir made a really good job and solved every issue I had with my code. The code I wanted to create is great. Would highly recommend for any embedded or IoT project.
Aamir delivered the project exceeding my expectations. Fast, professional, and highly skilled — exactly what you want from a freelance engineer.
