- As a Software Engineer 2 at Microsoft, my expertise in React.js, NextJS, Typescript and C# played a pivotal role in delivering high quality customer facing products in a reasonable time.- Lead the migration of TakeLessons.com from PHP on AWS to Microsoft Azure, leading to its scalability across diverse markets and daily user influx in the thousands. This was a complex project involving many moving parts, including public landing pages with large number of impressions, customer and service provider scheduling tools and booking flows and sharpened my ability to lead a team of vendors successfully.- Migrated the TakeLessons WordPress blog to Azure and created a NextJS based frontend that gave significant performance increase compared to the built in WordPress frontend.- Worked with the other Microsoft teams to integrate their products into the TakeLessons website using their APIs.- Implemented consumer intake funnels for the Bing Pros project with client-side telemetry, monitoring, alerting and AI rewriting. Used A/B experiments to help shape the direction of the product. Ensured the products adhered to Microsoft accessibility standards achieving gold level compliance. Quickly onboarded into this very large and complex codebase demonstrating my ability to learn new tools and technologies in a short period of time.
