Working with the World Bank and the Egyptian government for remote monitoring of public health infrastructure. This involves setting up embedded sensor deployment, wireless monitoring solutions, sensor data transfer via 3G, server database backend, and data visualization on the front end. The device firmware is programmed in C++. The server backend runs a REST API built on python and Flask. The data processing and visualization is also running python with pandas and matplotlib, seaborn, or bokeh.
