Maria PinedaFull Stack Developer
Software engineer with 5+ years of experience developing robust code for start-ups and big businesses. I’ve worked as a Back-End Developer using technologies like JavaScript( Node Express), TypeScript, Python 2.7 or 3 (Django, Tornado), and Blockchain (Smart Contracts using Solidity, wallet libraries for Bitcoin, Algorand and Ethereum). Also, I’ve worked as a Front-End developer using frameworks like Angular and ReactJs. I had some experience writing unit tests, and integration tests (cypress, jasmine). About my personal stuff, in my free time, I'm an enthusiastic reader of science fiction and I work on new technologies for small electronic projects using technologies like Balena Cloud, using hardware like Arduino, Raspberry, and Beagle-Bone or just building my own circuits.

KEA Electronics is a small start-up that I started with a couple of friends. KEA was a project related to the benefits of working with drones. We worked with the mapping of surfaces to measure areas, diameters, or distances using image processing. We used drones to get the necessary images. We won a local award called Banco de Ideas. We received finance to build software to upload to the cloud maps of areas that we mapped with drones. Functions: The object of this software was to measure and get a register about areas of interest for our customers. Created and launched a service that collects maps that were gotten from drone mapping. A customer could create an account and submit some photos of an area that He mapped with his drone, then we process and let see and measure the area that he mapped
