Staff Machine Learning Engineer 1

Glance, InMobi
  • •Led the design and development of a real-time recommendation and content serving system using (PySpark) Structured Streaming, and gRPC protobuf for communication over Kafka. [blog]
    • 01/2024 – 05/2024Bangalore
  • •Led and managed a high-performing team in the end-to-end development of recommendation systems, serving a user base of 100+ million daily active users while maintaining sub-500ms latency.
  • •Applied RL techniques such as MABs to optimize user experiences for less-engaged and sporadically active users using Thompson Sampling, beating our control by ~20%.
  • •Served as the key point of contact for a cost-saving initiative to minimize cloud expenses for various machine learning and data engineering workloads, saving upto 50k USD per month.
  • •Led the design and successful execution of PoCs focused on enabling machine learning on mobile Edge devices using TFLite.
  • •Collaborated with MLOps and Engg. teams to implement production-grade practices for ML systems, with monitoring, logging, and performance testing, primarily on GCP. [blog]
  • •Designed, built and iterated on Candidate Generation layers for an 'online-dynamic-feed' system using ANN methods.

    • Machine Learning Engineer 1, 2, 3

    Glance, InMobi
  • •Led the development of an automated content creation platform, generating over 95% of the content published on Glance, using a Engg. and ML stack built from scratch.
    • 08/2019 – 12/2023Bangalore
  • •Developed multiple image and text based automated solutions for deduplication, scoring, image ranking and search, image modifications/edits and publishing for the content creation platform.
  • •Led the efforts on building a content ranking engine that scores potential content for enabling strategic content selection for Glance.
  • •Deployed real-time streaming systems, leveraging Azure Eventhub and GCP pubsub, to enable content annotations and data enrichment of 'Glances' which helped several teams optimize their processes. Still the backbone of our Rec Sys.
  • •Developed a system to automatically convert landscape videos into portrait videos without losing out on the 'busy' or important scenes/objects of the video (based on some Google Apis, before AutoFlip was released).
  • •Developed and deployed Audio Classification and Content Moderation models for Roposo, a short form video application.

    • Data Scientist

    InMobi
  • •Addressed image blurriness issues in ad placements by developing predictive models for optimal image-to-slot sizing, alongside the implementation of super-resolution models.
    • 2018 – 2019Bangalore
  • •Led the creation of 'Creative Insights', a comprehensive solution that involved the evaluation and ranking of ad images. This was complemented by an Insights Engine designed to substantiate recommendations for enhancing ad image quality, used combination of CNNs and hand crafted features for button detection.
  • •Increased the operational efficiency of Ad moderation by introducing Ad de-deduplication (SIFT, Siamese Nets) and bad-ad detection computer vision systems (CNNs)
