At Mate academy, I refactored the feature-entry page, incorporating full-stack entity changes and updating page visuals to enhance user experience, resulting in a 48% decrease in user page interaction time.As part of a collaborative team, I contributed to the design and delivery of complex new features, reducing managers' time spent on performance metrics tracking by 23%.I provided continuous support for an existing feature, addressing bug reports, adapting implementation for specific business needs, and significantly reducing system errors by around 90%.Additionally, I led multiple teams of 4 to 7 developers in building e-commerce web applications, incorporating modern technology stacks.Furthermore, I mentored approximately 500 zero-experience developers, guiding them through a learning program and conducting lectures to help them secure their first jobs as web developers.
