• Lead Backend engineer for developing Placeable’s Workbench platform. The software manages customer’s location data, by syndicating the data to third parties such as Google, Facebook, Foursquare, etc. In addition, allowing the data to be managed by making mass edits, transformations and validations on that data.
• o Frameworks – Play 2.4-2.5, Scalatra, Finatra, Akka
• o Databases – Mongo, Elasticsearch
• The workbench platform comprised of micro-services that communicated with each other via REST Apis and pub-sub techniques.  We used Scala framework (mainly Play) to build our REST services.  The front end consisted of Node.js and React.js.  For messaging we didn't use a message broker system b/c latency was ok in our case so, instead of using a broker system like Kafka we leveraged MongoDB capped collections to send messages via pub-sub technique.
• We designed 4 main services to make up the software, Rules, Data, Mapping, Third-party service (Google Maps, Foursquare, Facebook, etc), and UI.  All services run inside Docker containers and are deployed to AWS using Marathon/Mesosphere.  Marathon handles the deployment configurations and ease of scalability.
