I develop mobile and web apps using Flutter and Django respectively. Here I get to choose what stack I use for projects as it is a very small team. I have a solid knowledge of OOP and its methodologies, so programming languages aren't a barrier for me. As long as I can think of it, I can develop it using any programming language best suited for the job.
I also assist the marketing team in my current job develop various marketing strategies whilst leverage on automated tools for collecting marketing data and analyzing them. I use Tableau and Anvil in conjunction with python for data visualization purposes.
