Customers' feedback about live coding sessions, code reviews, and freelance jobs.

Very smart and very competent! Has good fluency in programming languages. We worked on Java and Golang. Because he had worked on something similar before, he was able to help my project reach its full potential! Thank you again, Ale!

Ale Miralles is AWESOME!! He helped me with everything that I needed help with. He did this in a manner in which I could understand, being that I am a beginner. Had great customer service skills, a real people person!! I will be using him again and I will refer him to anyone that asks me for someone that can help them with programming as well!!

As always, Ale is incredible at achieving exactly what is needed in any time frame. He has great communication skills and replies so quickly. HIGHLY recommended!

~ Georga (Brisbane, Australia)

Ale is a fantastic mentor. He works quickly, ensures that he knows the full scope of the project, and was able to help me better understand C++ rather quickly. He responds very quickly (within minutes) and always has your best interest at heart. He is a true professional, and it was worth every penny.

~ John (US)
