From Legacy to Modern Angular: Refactoring and Delivering Projects with Confidence – A Case Study

I want to share my journey of delivering new pricing module at Prowly. Refactoring methodologies nad strategies that gave me the confidence to tackle such a large and business-critical feature. Whether you're facing a legacy rewrite or looking to refactor with confidence, this talk will provide practical tips and insights to help you navigate such projects with ease.

Tobiasz Ciesielski - Frontend Developer, Prowly PR Software | Poland

Hi, I'm Tobiasz, and I work at Prowly PR Software as a Front-end Developer. I graduated in Computer Science from Poznan University of Technology. I started my career at Prowly, where I've evolved and developed my skills. I'm a relatively novice programmer, but a very ambitious one. My focus is on delivering business value while maintaining high-quality code. For me, code readability is crucial to software development. In recent months, I've been working closely with the payment module, which has been quite challenging. After hours, I am also a triathlete, food lover, and self-development geek. My personal goal is to build a strong personal brand.

I'd like to share my breakthroughs that I've discovered while delivering new products, refactoring thousands of lines of code, and spending hours brainstorming with my great front-end team.
