DevNet Engineering,As a member of the DevNet Engineering team, my work included developing webpages, web applications and internal tooling. I worked closely with designers, content creators, and engineers from various Cisco business units to ensure seamless integration and a cohesive user experience across projects. I implemented modular web components leveraging content delivery APIs and a complimentary configuration UI, enabling the team to quickly build and customize pages for events and product launches through, significantly enhancing development speed and flexibility.In addition to web UI development, I delivered several high-impact tools and solutions, including:• Google Analytics Data Visualizer Plugin: Developed a Chrome extension that overlays site analytics data on top of DevNet webpages, complete with a toolbar for real-time adjustments and insights.• Server-side Rendering of Content with AWS: Boosted site performance by implementing server-side rendering, optimizing content delivery via AWS CDN and Lambda, improving both speed and scalability.• API Insights: Built an internal tooling web application to validate and analyze API documentation, ensuring Cisco's API offerings consistently met high standards of quality and compliance.• Frontend Testing Automation: Developed a testing solution utilizing Playwright with reusable components that allows users to plan UI tests easily through yaml file test plans. Integrated this solution into the Jenkins pipeline to run both periodically and upon service deployments, enhancing automated testing capabilities.With a strong focus on efficiency and reusability, I contributed to making the DevNet platform both user-friendly and highly maintainable, supporting long-term scalability and adaptability.
