As Technical Lead, I spearheaded the migration of the Bancanet platform from Angular version 10 to 17, significantly enhancing development efficiency and product quality by leveraging new features and performance improvements of Angular 17. Key achievements include a 30% improvement in build and deployment times, a 25% increase in the rate of introducing new features, and a robust documentation framework that reduced the learning curve for new team members and improved overall project knowledge management.
