● Led the development of a B2B marketplace (https://business.blibli.com/) to replace SAP C4, resulting in cost savings of $20m in terms of SAP licensing fees and a 25% increase in efficiency for Blibli's business operations during the initial adoption phase. ● The new B2B system is integrated well with the existing catalogue, shipping, warehouse systems at Blibli. Technology platform include Java, spring boot, microservices, Kafka, MongoDB, PostgreSQL, GCP● Oversaw the re-architecture of a price intelligence application, achieving a 30% increase in scalability and enabling automation across 100% of pricing workflows. ● Identified and abstracted the main business processes of price intelligence out into separate workflows eliminating dependencies helped multi-threaded processing which can scale depending on the volume of data from a monolithic application architecture. Leveraged Java, spring boot, JMeter, JavaScript, cloud based commercial proxy nodes technologies for implementation.● Spearheaded a POC for dynamic pricing conditions using Drools and Spring Boot, leading to the publication of a pricing intelligence paper and implementation in live systems. The driver for this change was the large duration needed to update pricing data to various systems which reduced the efficiency of dynamic pricing. ● Implementation of scalable dynamic pricing based on business rules opened the door to a reusable dynamic pricing engine that replaced a single price engine that had to propagate price changes to different systems.
