Building AI solutions that actually solve real problems
I believe artificial intelligence should enhance human capability, not replace it. That's why I focus on creating AI applications that automate the tedious stuff so businesses can focus on what matters most—growing and serving their customers better.

Stalin is a great front end dev with full-stack knowledge. He has great initiative and work ethic that allowed me to delegate problems and concepts instead of having to give bite-sized instructions. More importantly he is a good person with a great attitude. It has been a pleasure working with him.
