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

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

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

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)
