The Hue Bridge is an embedded Linux platform controlling lights in millions of homes.· Implemented new features using C, C++, Python and Shell plus tests in C++, Python and Node.js.· Led the redesign and implementation of provisioning + fw updates + analytic collection for the Hue Bridge, using Google IoT MQTT services.· Led the team responsible for the filesystem migration in millions of devices. From design to release, all accomplished without unexpected failures.· Introduced an architecture where daemons exchange data with each other and with the cloud through a broker. This replaces HTTP, gRPC and Websockets.· Introduced Python and Rust as alternative languages for embedded development.· Introduced SQLite as a way to store data inside the product. Also lead the team that carried out the performance and robustness tests that backed up the decision.· Helped improving the security of the system by introducing HTTPS using NGINX. · Tuned code to increase uptime and reduce communication latency with the cloud.· Improved the data logged to the cloud to ease the diagnostic of issues.· Ported the latest OpenWRT to the hardware, including new kernel drivers.· Debugged an fixed performance issues of musl libc.· Participated in the evaluation and selection of new hardware (CPU + WiFi).· Found a silicon bug in the MIPS CPU.· Temporarily relocated to Palo Alto to assist the development of the Hue Play HDMI Sync Box firmware and hardware.

Pycom is a startup that provides low-cost, low-power, Python programmable devices that enable companies to build IoT-ready products that can connect to the most popular LPWANs available. Initially hired as a software engineer, I also worked in hardware and firmware:As software engineer:· Developed Pymakr, an IDE that connects to the devices (Windows/Mac/Linux). · Co-designed the architecture of Pybytes (middleware platform).· Performed as architect of a platform to integrate the e-commerce with a logistics provider.· Developed the backend service that handles device registration and upgrade process.· Developed a multi-platform firmware upgrade tool for Pycom devices.As a firmware/hardware engineer:· Participated in porting MicroPython to the ESP32 architecture and it's peripherals.· Designed the hardware and firmware of two products (Pytrack/Pysense). Modified the PIC’s USB stack, increasing data transfer speeds up to 5 times.· Designed a price-sensitive (< $1) shield to reduce power consumption of some products. Firmware included a single wire protocol implemented in software.Other activities: sysadmin (UNIX), product support on forum and documentation writing.Technologies: C, Python, Javascript (Node.js), SQL, Qt, PIC assembly, Unit Testing, FreeRTOS, ARM, ESP32, USB, MQTT, Bluetooth LE, LoRa, Sigfox, SMT.

· Negotiated projects with different customers.· Developed two different desktop apps, one in Qt and the other in C#. Both control devices over serial port (with their own protocols) and use databases as storage.· Designed hardware and firmware (in C) for an inductive-loop vehicle detector.

Assigned to the development of Wuelto, an e-commerce of this century:· Promoted the first brainstorms, giving birth to ideas that attracted $150000 in investment.· Created algorithms to mimic human decision taking. Search, vendor ranking, and product discovering were improved by using technologies like fuzzy logic and genetic algorithms.· Implemented a cloud based environment that resizes with demand, with estimated cost reductions of more than 60% compared to a static architecture.· Lead a team of 4+ engineers.· Introduced Scrum as managing method, and online tools for project management.· Conceived test sandboxes to free developers from doing system management. This improved the team efficiency by 20%.Technologies: C/C++, Javascript (Node.js), PHP, SQL, NoSQL.

Developed different software solutions for the mediation platform Among the challenges:· Implemented a recovery procedure that spared the company $4.5 million in loses.· Improved the uptime of two systems more than 1000 times by carefully debugging them.· Reduced execution time of a batch process by optimizing it's SQL (1500 times faster).Technologies: C, Java, SQL, SOAP, shell scripting (bash).

This startup created a line of Automatic Meter Reading products, based on 802.15.4 and GPRS.· Reduced the manufacturing costs by 45% without sacrificing quality by reviewing the hardware.· Tuned the original Zigbee stack, making it >20\% more energy efficient.

In charge of the design of a vehicle tracking and security system:· Achieved a personal goal of 25% of price reduction over the originally estimated costs.· Developed the firmware for this product, including a scratch implementation of a RTOS kernel.· Developed a server in C++ for remote control and monitoring of the devices. · Implemented cell triangulation to locate vehicles without GPS.· Reverse engineered the Garmin maps format.Technologies: C++, multithreading, TCP/IP, SQL, Web Services, Microchip PIC, GPS, GSM, I2C, battery charger, SMPS, SMT.
