Saved my team more than 50 man-hours by refactoring and decoupling reusable UI components into an open-source library by using Angular, RxJS, and Electron.

Greatly enhanced our UX by decreasing the time needed for generating complex queries (for a personalized search engine) by 50-70% by implementing a chatbot that can parse natural language using Javascript, CSS, React & Redux, functional reactive programming, machine learning (NLP and Google Vision).

Highly reduced the amount of time spent by our client for data analysis by more than 100 hours/day at the organization level by generating charts and reports using Google Maps API, Oracle SQL, MSSQL HyperApp (flux), Subversion, REST, JQuery and Git.

Saved my team more than 10 hours per week of development time, slow code navigation and bug fixing by implementing clean code abstractions, removing duplication, extracting reusable components and redesigning internal data structures.

Cut down weekly transaction processing time for our client from over 5 hours to less than 30 minutes using C++, MongoDB, and by optimizing Oracle SQL queries.
