- Associate ArchitectCharmboardFeb 2018 - Jul 2018 (6 months)Designing and scaling the existing infrastructure by revamping the existing code and implementing microservices architecture. Implementing structured logging and monitoring using the ELK stack. Writing wrappers around the deep-learning models , exposing it as a service and pipelining the data to these services using the pub-sub model. Developed an orchestrator to send GPU intensive tasks to efficiently use the available GPU cores and to spawn-on and spawn-off new instances based on load.
- Senior Software EngineerCrowdanalytixJan 2017 - Feb 2018 (1 year 2 months)Designed and developed a product that enables its users to build their own image models online , by uploading sets of images , specifying the model parameters (such as epoch , bath size) ,testing the built models for accuracy and precision and reiterating the build by tweaking the settings. Designed and implemented high available and low latency APIs (API as a service ) catering to requests at the rate of 1000 req/sec. The data from the API calls were processed through various set of data and image models and the predicted output of these models were sent back as response to the API call. Integrated a dynamic way to create google instances with GPUs, create images models in those instances, move the created models to a google bucket and lat
