Currently building Nooble.fans, a comprehensive content platform from the ground up. I'm handling everything from architecting the backend API with NestJS and PostgreSQL to creating the frontend experience with Next.js 15. The platform features advanced media processing with watermarking and HLS streaming, secure payment integration with CCBill and Stripe, and a sophisticated subscription system. I've implemented JWT authentication with 2FA, built a complex role-based access system, and created an intuitive content management interface. The project showcases my ability to deliver enterprise-level security and performance while maintaining excellent user experience.

I redesigned and rebuilt the product listing page with a focus on performance and user experience, while leading the successful migration of the platform from Shopify to a custom Next.js stack that improved flexibility and reduced long-term costs. I directed the rebuild and ongoing maintenance of the cart and checkout systems, which serve as a core foundation shared across all flagship products, and implemented optimizations that improved conversion rates. I also oversaw the integration of third-party fulfillment solutions, enabling the company to manage international logistics for partners lacking global fulfillment capacity, while maintaining and streamlining the fulfillment services pipeline to ensure reliability, scalability, and operational efficiency.

During my time at ESX, I focused on making it easier for people to buy movie tickets online. I completely revamped the checkout flow and made the entire experience mobile-friendly, which was crucial since most users were booking tickets on their phones. I also spent time cleaning up the codebase – you know how it is with legacy code! The refactoring work I did made the app noticeably faster and much easier for the team to maintain. It felt great knowing that my work directly helped increase sales and made customers happier with their experience.

Working at Coursera was amazing because I got to contribute to a platform that's genuinely changing lives through education. I built new features using React and TypeScript that made the learning experience smoother for millions of students worldwide. The collaborative environment was fantastic – I worked with talented people from design, product, and backend teams to ship features that learners actually needed. Maintaining high code quality was a big focus, and I learned so much about building scalable applications that serve users across the globe.

At OpenInvest, I got my hands dirty with both web and mobile development, working on fintech applications that needed to be rock-solid reliable. I proposed new engineering practices that streamlined our workflow and made the whole team more productive. Performance was critical in the financial space, so I spent a lot of time identifying bottlenecks and optimizing the user experience. I also contributed to documentation and helped integrate cutting-edge technologies that kept us ahead of the curve. It was my first real taste of fintech, and I loved the challenge of building user-friendly interfaces for complex financial data.
