ProjectsLive Streaming platform: Using AWS elemental, developed an administration portal and a backend service to launch media streaming infrastructure. Using the application, a producer was able to serve an ingest endpoint for RTMP content and make the output available on multiple streaming formats (HLS, DASH, MS Smooth) using a CloudFront distribution.Conference WebApp:Based on WebRTC, developed a Web application to serve video calls directly using the browser. The service was available for both desktop and mobile browsers, up to 9 participants per room, with hand raised feature and screen sharing. Ultra-Low Latency PlatformBased on WebRTC and AWS, developed a management portal to serve conferences (1 to Many) to an audience, with the possibility of inviting a co-streamer, and an integrated chat. The service also allowed to push content using RTMP. The backend and frontend were hosted using AWS, and additional features like sending email invitations, and token generation for invites, too.Audience Interaction Software:Based on WebRTC and AWS, developed a backend service to manage the viewers' interaction within a live event. The service was able to handle high volumes of interactions, like tagging, video wall generation, and updates, and real-time notifications. The application exposed a Rest API and a WebSocket server and worked mostly based on the Event Sourcing pattern, with CQRS. Most of the application workflows were solved by applying the Saga pattern.Transcription Service:Based on Amazon Transcribe and Agora.io created a containerized service that subscribes via WebRTC to a streaming channel and outputs the English transcription. The audience was able to receive the transcription through a web socket connection.

Awards: Delivery Excellence Award 2Q 2019: Successful turnaround and recovery of rollout, regaining the customer’s trust and Nokia’s position as its best vendor. Projects 5G Trial for Telecom Personal: Evaluated new antennas and node performance in a controlled environment to check configuration parameters, and measure max throughput. Refarming LTE 1900 on Litoral Argentina Network for Telecom Personal: Reconfigured the nodes to switch from 3G 1900Mhz to LTE 1900MHz without in-site intervention. Also, enabled carrier aggregation and MIMO to improve user throughput. LTE Optimization on Rosario city for Telecom Personal: Proposed and applied Tilt changes on city sites. Also monitored and proposed new features that improved the user experience (more throughput, less dropped calls). RET (Radio Electrical Tilt) Normalization over the whole Litoral network: Created an automated method to check the configuration parameter for the RET devices across the network. Managed the rollout crews to make the physical configuration changes when needed and corrected the logic configuration parameters to normalize the network configuration. Delivered documentation and generated a new standardized process to apply on new site deployments. Regained customer’s trust due to successful results of this normalization.

Projects Universal controller for vending machine: Designed hardware and developed firmware for a controller to support multiple currency detector devices. The configuration was updated through USB from a PC and was able to work using Cash and Coin and Cashless (card) detector devices. Programmable Logic Controller with a touch user interface: Developed firmware to support a custom instruction set to generate small applications within the controller. This device was used by several companies to develop their own applications for field operators. Test equipment for the production line of household appliances company: The device was designed to work on a production line. Before packaging, the products should pass a semi-automated test using this test equipment. Industrial Shutdown System: This device was developed to work under extreme weather conditions (-40 ˚C) so selecting the components was a critical task. The device counted with a built-in terminal accessible through a serial port. UDP socket server development for the massive data collection on farming industry equipment: C++ application running on an EC2 instance that collected data from multiple UDP connections and sent responses to the client and also stored the incoming data. Design of Hardware for high voltage lines current measurement using Rogowski coil: Designed a low noise interface to capture the measurement of a Rogowski coil that measures high voltage lines above 1000 A. The hardware was designed to provide a good low-frequency response with CC cancelation but keeping a low phase delay. WEB Interface programming for supervision of medium voltage cameras equipment: This simple web page was developed using plain HTML and CSS since it should run on an embedded web server. Design of HW and SW for parking meter with 2G/3G connectivity: Multilayer design of a parking meter device with a CPU (4 layers) and a 2G/3G modem (2 layers). Developed drivers to support RFID, communications, and data display.
