Professional experience

Hi,
  I am a Java group leader at Tikal. Tikal is a technological house that helps other companies to raise the bar on their applications.
Some of the projects I have done in tikal are:

Client Projects

Behalf / Data Architect & Implementer – 2017

Design and implement an ETL pipeline to stream data from salesforce to Bigquery using apache beam on top of google dataflow. The task included understanding the amounts of data, and the api’s that salesforce supports.  The delta changes needs to be transferred every 15-30 minutes across all tables, with configuration options to add tables and columns in the future without code changes.. Apache Beam on top of dataflow was chosen as the data pipeline for it’s abstract sdk for processing data. Google App-Engine was used as the scheduling mechanism, and  google app script as the monitoring dashboard.

Java Architect startup – 2016

Help a startup to rearchitecture a monolithic application to a micro-service platform. This included breaking up application to multiple services with kafka as the communication bus. Help redesign application for scale by introducing rx-java in the software tier along with clustering of servers, and cassandra as a backend database for scaling data. Help introduce more functional style programing using javaslang framework. On the devops side, I helped create the Cloud-formation structure on top of AWS for clustering of servers.
