Mainly focusing towards team building, managing and growth of team members (technical and personal), cross team project management, roadmap discussions, coordinating with product, etc. Have been working hands on with technical projects and contributed towards coming up with new projects for search relevance improvements (Lyrics search, Phonetic handling, Named entity detection, etc.), system optimization and infrastructure upgrades. DeepSearch -> Conceptualized, prototyped, developed and launched a deep learning neural network model for personalized search results ranking. Worked on the tasks related to 1) Defining the complete model architecture. 2) Deciding on the relevant loss and metrics. 3) Analysing and preprocessing of training data. 4) Training and fine tuning multiple model instances. 5) Involving team members to productionize the trained model. 6) End to end automated training and deployment pipelines. Migrating Search service from AWS to Azure ->Mainly was involved with planning the migration strategy, managing team members and helping them with blockers, assisting them in timely completion of tasks and providing team with relevant training to improve the overall understanding of the systems. Infrastructure Optimization -> Designing a new architecture for SOLR cloud setup to optimize on search relevance and latencies. Mainly worked with tasks related to project design and helping the team with implementation details. Migrating Search service from Azure Singapore to Azure India -> Mainly responsible for guiding team members in planning of the complete project, deciding on smaller tasks to achieve the overall objective in timely manner, helping with cross team coordination for solving blockers, zero downtime for users and facilitating relevant training related to systems.
