Working on Database CPU utilization reduction to reduce DB server cost by downsizing them. To achieve this I worked on projects like optimizing sql queries, increase cache-hit ratio, analyzing existing client API usage to propose better API utilization by clients, optimizing sql schemas and indexes etc. This was all done with the target to reduce peak DB CPU usage to safely downsize db servers.2. Analyzed usage of new cache frameworks like Hazelcast to distribute cache across multiple servers and reduce in memory server heap requirements. We were able to increase cache size by 4 times and reduce dependency of db to fulfil sql queries which can be done by cache.3. Scaling and optimizating key scheduled jobs in security master that were SLO bounded. These jobs were earlier highly unoptimized and could even take a day to run a single job. Using graphs and hierarchy knowledge, I was able to optimize these task to run in less than 5 minutes and less than 1 hour in worst case for high input sizes. This provided cost benefits on compute cost as well.4. Worked on several miscellenous projects that were key for client satisfaction and keeping security master in sync with latest trends. This included stabilizing arcesium client sdks etc. Show less

I was involved in working on analyzing and implementing different supervised and unsupervised machine learning models to automatically predict annotation labels for text and image data types.I was responsible for building the complete UI to annotate text data type and integrate it with backend to store the annotated labels and automatically suggest labels for text files.Google cloud platform was the major cloud service provider being used at Labellerr, so I got the chance to understand the complete lifecycle of deploying the backend APIs and frontend app on google compute services and using it's various managed ML APIs like image processing, speech-to-text conversion APIs etc. Show less
