I was involved in the full cycle of software development: idea exploration; project design, planning and deployment scheduling; building software; maintenance and continuous improvement. I utilized Ruby on Rails, React and PostgreSQL to build: - internal backend tools and scripts like auto-generated e-contracts, automated payment reconciliation and refund tool. My work added more management visibility into the company's money flow along with allowing us to disburse money faster and generate revenue earlier in 20% of cases. - customer facing tools like identity verification pipeline, campaign management and analytics dashboard. My work helped to drastically improve customer experience and reduce the number of support requests by 30%. ### AI Developer @ KATERRA Jan 2019 – Jan 2020 | Toronto, Canada Area Smart thermostat development (similar to NEST). I proposed and developed an occupancy model based on humidity and temperature sensor signals. A provisional patent was filed based on my invention. I used Python (including Pandas, Scikit-learn, Statsmodels, Matplotlib) to run experiments, develop and validate the occupancy model. ### Data Engineer / Software Programmer @ Real Tech Inc. Jan 2019 – Jan 2019 | Toronto, Canada Area I brought automated water quality analysis to the customers by extending an open source IoT platform used by the company. I used Python (including Pandas, Scikit-learn) to train ML models. I deployed inference services on AWS and on company owned servers with Flask. I used JavaScript (including D3) to build customer facing dashboards for real time water quality analysis. My work resulted in full automation of the water scanning and analysis process. Now the scans are available in real time with an interactive UI instead of having a technician to run the analysis and provide customers with the results and insights. ### Python Developer @ Coursera Jan 2018 – Jan 2019 | San Francisco Bay Area I developed assignments and automated graders for Self Driving Cars courses offered by the University of Toronto. More specifically, I contributed to the following topics: visual odometry, PID controllers, stereo vision, simulation. I used Jupyter Notebook (Python, OpenCV, CARLA) for developing assignments and Python for building scalable graders with Docker containers. These courses were taken by 60K+ happy students. ### Software Developer @ Salu | Health Gauge Jan 2018 – Jan 2018 | Edmonton, Canada Area I designed and developed a full-fledged Android/iOS app using JavaScript (React Native). My work included designing UI/UX and app architecture, building Bluetooth communication with sensors and dashboards for signal visualization. ### Research Assistant @ University of Alberta Jan 2015 – Jan 2017 | Edmonton, Canada Area 1) Thesis: Automated Tool for Visual Progress Tracking of Construction Projects I proposed and developed a framework for automated progress tracking of construction projects via drones. My work relied on using SfM, MVS, ICP, Gaussian Mixture Model, CPD, Hausdorff distance, Matlab, Python, Bash, C++. The framework developed by me improved industry standard computation time in 10 fold and cut down number of manual steps required.
