Won 2nd prize at annual hackfest WeHack 2015, VIT University. I was a part of team of 4 undergrad engineers, our track was IoT, in 24 hours we developed a working prototype of 'Polygn', it was a machine learning assisted intra campus navigation system, we worked throughout the night, developed the hardware, webapp and a demo presentation. I was in charge of webapp and demo presentation. Finally when the results were announced it was already more than 35 hours without any sleep, our names were announced. Out of more than 500 brilliant ideas, by approx 1500 students, ours stood out.
