Work Experience

ActiveSphere Technologies Private Ltd Feb 2012 - Present

Working as a consultant. Some of the client projects include

Midtrans - a leading payment gateway in Indonesia. I was part of the team which develops the snap product, an embeddable payment form. I helped them migrate their notification system to Elixir stack to improve throughput and resource consumption, built the initial version of centralized auth server based on oauth protocol, built a Kafka to Elasticsearch data ingestion pipeline in Elixir, built a streaming report generation system that could export hundreds of thousands of rows of data in xlsx and csv format while maintaining constant memory overhead. Some of the libraries — namely redix_sentinel, barlix, xml_stream and zstream — are open-sourced.

EnerNOC - I was a core member of the team that developed Energy Manager, a web app used by professionals to visualize and understand energy usage. I have touched many parts of the system. My main contribution includes writing and improving various charts like load profile, consumption, heatmap etc using d3. I have also written an automated test system to generate charts for various combinations of state and compare their screenshots with previous versions to catch regression and a library named μ to compress url parameters.

Placeley - I was part of the two member team that developed the web app and the backend for placeley, a geo location social network for places.
