Experience
NELA Language App
Currently (during the onboarding phase), more than six teachers and over 20 Students are using this app.
The frequent changing of requirements had made the app very slow. I contributed to a microservice-similar infrastructure and reworked the architecture, which significantly increased the performance and user experience.
Supported languages - German, English, Spanish.
JUST-SELL.online
https://just-sell.onlineCurrently, the Project is in the beta phase and is being tested in multiple shops by experienced shop owners in industries such as automotive, apparel, gastronomy, and food supplements.
Some of the shop functionalities include an offline-first with PWA application, a powerful JavaScript image editor with an AI background, the ability to remove and add stickers, write text, and add filters. It has an inventory system, does tax calculations, and is a simplified yet highly flexible options and variants system that supports unlimited languages and currencies.
The system of the shop is so lightweight and optimized that it can handle more than 1,000 shops on a 20GB, 1GB ram, and a 1CPU server!
