NX4 is a web-based visualization tool for the exploration of aligned viral sequences. The tool was born as an alternative to matrix-based MSA visualizations. This is an open- source project maintained by a small group of web-developers, visualization researchers and computational scientists.

I collaborated with researchers from Northeastern University and the Broad Institute of MIT and Harvard.


Web developer, including owning the Dev-Ops. My role was primarily to help build the visualization tool using modern web technologies and creating development and deployment processes and environments.


Published an article in Oxford Bioinformatics about the application and its features
