Designed, developed and tested the electronic control of a trajectography radar Vitro 778C with a PIC microcontroller.
Developed and tested the GUI to communicate with the radar in Java and replaced the radar's main computer with an ARM microcontroller.
Wrote and developed the electronic design of the boards used for the PIC microcontrollers and performed real-time testing of the radar antenna's pedestal movements.
Worked on the simulation of a 200Gb/s optic chip for communication over continents for Clariphy Inc. The solution is a real-time digital processor of optical signals; presented at the OFC (Optical Fiber Conference) 2013 to clients of the organization - earning 10 new clients after the presentation. Handled different responsibilities over the project lifecycle and a team of 5 developers. Oversaw the development of algorithms using previous research and IEEE papers.
Olapic is a company dedicated to collecting pictures from social networks like Facebook/Instagram. The acquired pictures are then sold to companies like Adidas, L'oreal, Sephora and Disney. Worked on Olapic's REST API on its main curation platform for the selection of pictures from social media apps. Utilized PHP for the backend structure, Elasticsearch as a search engine, MySQL for database and Redis as a caching tool.
Developed REST APIs as widgets on websites for L'Oreal, Disney, Halfords, Sephora and Hyatt. Replaced legacy APIs with the capacity to receive 1M+ requests per hour on most sites and lots of data loss on the project. Worked in a collaborative environment on the development of new solutions from scratch for clients; by increasing the number of requests processed by the new APIs with the capacity to process up to 10x its usual capacity on special dates like Black Friday without any problem.
Created a Rest API for Exotic Objects' collection for Christie's, the London based auctioneers; raising GBP 200k+ for the collection which was considered a great success. Christie’s is a name and place that speaks of extraordinary art, unparalleled service, expertise and global reach. Worked as a backend Engineer for the REST API and the Admin.
Created an authentication and authorization server for Monotype; the service included a REST API used by other services on the platform to authenticate and authorise users. It also included a UI that allows Admins to create, update and delete users from the platform, and also assign permissions to them for the different services on the platform.
