As a software team lead, I worked on building 360-degree virtual reality platforms and custom CRM systems using Angular, Next.js, and Node.js. I also led a major e-commerce project where I built a system to connect multiple marketplaces into a single dashboard. This system handled stock synchronization, dynamic pricing, and real-time order tracking across major marketplaces in Turkey. By developing these solutions, I helped the business simplify complex workflows and scale its online sales more efficiently.
