An Experimental Study of Context-Free Path Query Evaluation Methods

SSDBM'19

Master's Thesis

Neo4j

Malmö, Sweden

I integrated a new type of index into the Neo4j query pipeline. This change affected the full query pipeline; query planning, query execution and transaction processing (index maintenance).

I also looked into which type of query and data patterns best benefited this type of index to speed up query performance and found some useful heuristics for finding use-cases that can be sped-up with this index.

Research Internship

Neo4j

Malmö, Sweden

An experimental study on querying recursive (context-free) path patterns in graph databases. I examined existing literature, built a prototype, ran experiments, evaluated performance and presented the results in a final report.

This internship was done with supervisors from both Neo4j and Eindhoven University of Technology.

This study was expanded and published in SSDBM'19 in July 2019.

Support Volunteer

Telegram Messenger LLP

I helped Telegram users with their questions regarding the app and platform. This included troubleshooting and triaging bug reports and feature requests, and escalating relevant issues to the appropriate internal teams.

I also suggested new ideas for the platform and made an early Android prototype for user-configurable themes, which led to the feature being implemented across all official apps.
