Natural Language Cache

An online cache for documents that can store document content and metadata and analysis results from different analyzers. This enabled new scenarios for multi-paragraph and whole document analysis which previously wasn’t possible for Microsoft Office online products.

Technologies: C#, ASP.NET, Redis.

Implementation of a New Payment System

I enabled a new payment system in the core banking system through a web service.

Technologies: Java, IBM MQ, jBASE

Search API

I developed a search API which increased search speed 5x-10x depending on the query. I switched from MySQL queries to Elasticsearch. The search API was used internally to search for users and their data on a lot of parameters and filters.
Elasticsearch was used just for searching while MySQL was still used for data storage. In order for the search to work, I used Logstash to sync new data so that the search would work in almost real-time.
