Decyphering and reimplementing a project coded and commented in Chinese from C#/ASP.NET to Python/Django/Vue.js stack. Its business logic has to do with reducing across entire DB tables, using iterative/state-dependent numerical methods to evaluate physical properties and give out quotes (or total cost(s)) - I recognized most of the underlying math constructs and produced a much cleaner analytic versions where possible under the time constraints.

At the moment I'm working in a very specific system engineering stack, primarily using C++17/C99 and some of my Python/(ba)sh experience. The current project is choking with tasks that our small team has to skip over, we do our own QA, tasks that are getting closed often obscure their customer value; while I can manage these things, I believe that focusing on engineering and having tangible metrics for career advancement motivates me the most.
