Projects

Losant

At Losant, I led the design and development of real-time monitoring dashboards for IoT devices, enabling near-zero latency updates through MQTT and WebSocket protocols. I architected and implemented AI-powered predictive analytics features using TensorFlow.js, which reduced device downtime by 15% by detecting faults early. I optimized the frontend using Next.js, leveraging advanced server-side rendering (SSR), incremental static regeneration (ISR), and dynamic routing, improving dashboard load speeds by 30% and boosting user engagement. I established robust CI/CD pipelines with GitHub Actions and Azure Pipelines, automating deployment workflows and achieving 40% faster releases with zero downtime. Mentoring a team of 5+ developers, I enforced coding standards and best practices, including ESLint, Prettier, Jest, and Playwright testing frameworks, while collaborating with product owners and UX designers using Agile/Scrum methodologies to iteratively deliver impactful features.See More

Wayfair

At Wayfair, I was involved in a project aimed at enhancing the user experience on our product pages, which are visited by millions of customers daily. The goal was to improve page load times and overall performance, especially during peak shopping periods. I led the initiative to refactor our frontend architecture by migrating from a monolithic structure to a modular component-based system using React. This transition allowed for more efficient updates and better scalability. Additionally, we implemented server-side rendering (SSR) to improve initial page load times, which is crucial for SEO and user engagement. One of the challenges we faced was ensuring that the new architecture integrated seamlessly with our existing backend systems. To address this, I collaborated closely with backend engineers to align on data fetching strategies and API optimizations. As a result of these efforts, we achieved a 25% reduction in page load times and saw a 15% increase in conversion rates during high-traffic events like Way Day. This project not only improved the user experience but also contributed to a significant boost in revenue during key sales periods.See More

ShipStaion

At ShipStation, I worked on improving the order tracking dashboard, a major tool used by over 130,000 e-commerce merchants managing shipments. My role was to enhance both performance and usability. One of the main tasks I handled was refactoring legacy React class components into functional components using hooks, which improved code maintainability and reduced load times by approximately 30%. I also introduced Redux Toolkit for better state management, which improved app responsiveness. A major challenge was handling real-time updates during high traffic spikes, especially around busy shopping seasons like Black Friday. To address this, I combined efficient polling with WebSocket updates to keep the dashboard fast and accurate without overloading servers. As a result, customer satisfaction scores related to order tracking improved by 15%, and support tickets related to tracking issues dropped by 20%, positively impacting user experience and reducing support costs.See More
