• Full stack development and data-engineering on the Structured Data Platform team which collects, stores and serves structured data that organizes Udemy's content

• Designed, implemented, collaborated cross-functionally, and led development on a classification framework with 3 engineers for over a year

• This framework is used by users and various internal teams to classify any content on the platform and relations between content in a graph-based model, to help improve personalized learning

• Built the framework using Python, Django, MySQL, and Elasticsearch, and also designed it to be database-agnostic to scale

• The framework is estimated to reduce future engineering work on 10+ future use cases by over 50%

• Developed and evangelized across the engineering org an abstraction for developers to more easily execute cross-DB joins with Django by modifying the ORM

• Full stack development and data-engineering on the Structured Data Platform team, which collects, stores and serves structured data that organizes Udemy's content

• Optimized user and instructor flows related to leaving course reviews using React, Django, and Django REST Framework

• Conceived of, implemented in SQL, and created ETL pipeline for a novel scoring mechanism to differentiate similar courses based on structured user feedback

• Led efforts to speed up an ETL generating weighted average computation for all courses, resulting in a reduction of the end-user-facing delay by 50%, reducing instructor complaints by over 30%

• Designed and built a profanity filter pipeline using Django and Celery that processes over 30k reviews daily

• Aided in migration of serving course reviews from MySQL to Elasticsearch to improve reliability, speed, and scale

• Designed, built, and maintained over 12 ETLs, resolving any critical bugs within one working day

• Full stack development on the Discovery team that supports various features on the shopping cart and course landing pages, which account for over 60% of site traffic

• Built numerous A/B experiments using Django and React which contributed to an estimated 6% increase in revenue over a year

• Migrated Angular components to React and implemented lazy loading, resulting in a 20% decrease in page response time on course landing pages

• Designed and implemented a common javascript module used to track user page interactions, used to improve funnel optimization

• Built business-critical financial analysis app with AngularJS, used by the largest real estate project in US, to track construction at a rate 3000% faster than previous processes.

• Utilized Test Driven Development (TDD) with Jasmine and PhantomJS for unit and end-to-end tests.

• Coordinated with 2 major stakeholders to determine user needs, project features, and back-end API.

• Engineered RESTful API using Ruby on Rails to create users, and handle notes in an app for authors.

• Architected PostgreSQL database using ActiveRecord to establish one-to-many and many-to-many relationships between Users, Notes, Prompts, and Email Queues.

• Designed highly interactive UI/UX using React and used Webpack to inline static assets, improving page load times by 20%.

• Animated performant HTML5 web game using Three.js and Redux to drive 60 fps in the browser.

• Followed agile development methodologies to rapidly prototype new products for clients (startups + enterprise)
