Session type: Full talk of 40 mins Status: Rejected


Developing Personalization platform for improving customer experience of millions of Indian travellers
- FeatureStore with Feature compute & Serving
- Why Feature Catalog cannot be an afterthought, Metadata analysis is Key to succeed in transforming development of pipelines with eye on Data Quality!
- Microservices is not only about services only its more about Data, we call it Data APIs
- Lessons learned from the Growth projects(personalization, wallet/discounting, Gamification


MakeMyTrip - India’s #1 online travel platform having more than 70% of the traffic from mobile apps embarked on a journey to revolutionize its customer experience by building a scalable, personalized, machine learning based platform which powers onboarding, in-funnel and post-funnel engagement flows, such as ranking, dynamic pricing, persuasions, cross-sell and propensity models.
For a company like MakeMyTrip, the next wave of consumer growth is driven and powered by data products for personalization, context-aware mobile experiences. Having a better data architecture to ingest user activity streams (events), processing and data APIs enable a foundation for real-time feature generation for machine learning models.

Topics include:

  • Why common feature-store, removing dataset fragmentation caused by usecase-by-usecase approach!
  • Productionizing ML via standardization : MetaConfigs & FeatureCatalog | Reducing Data-Tech Debt
  • Developing Real-Time Serving store over Spark Streaming, Kafka, RocksDB, Akka HTTP Data APIs
  • Lifecycle of feature generation | Online(Near Real-Time) & Historical(Batch) Compute
  • Consistent Feature Engineering & Model Deployment for DSA: DataScience Automation

As Technology we leverage Kafka, Spark (Streaming, SQL), Scala, Python, AWS (S3, EMR, Glue and other services), DRUID, Hive, Presto, Cassandra, RocksDB, Redis, Akka HTTP

    Hi Piyush,

    Thank you for submitting a proposal. We need to see detailed slides and a preview video to evaluate your proposal. Your slides must cover the following:

    • Problem statement/context, which the audience can relate to and understand. The problem statement has to be a problem (based on this context) that can be generalized for all.
    • What were the tools/frameworks available in the market to solve this problem? How did you evaluate these, and what metrics did you use for the evaluation? Why did you pick the option that you did?
    • Explain how the situation was before the solution you picked/built and how it changed after implementing the solution you picked and built? Show before-after scenario comparisons & metrics.
    • What compromises/trade-offs did you have to make in this process?
    • What is the one takeaway that you want participants to go back with at the end of this talk? What is it that participants should learn/be cautious about when solving similar problems?

    We need your updated slides and preview video by Jun 17, 2019 to evaluate your proposal. If we do not receive an update, we’d be moving your proposal for evaluation under a future event.

      Hello Abhishek, pls. checkout slides (link added in slides section), do let me know in case more details are required now. Thanks a lot!

        Thanks for the slides, Piyush.

        Here are my comments:

        • The proposal still lacks the problem definition. What is the problem you’re trying to solve? Right now you jump stright into your platform, without introducing the fundamental problem.

        • The presentation needs to be updated to explain why the solution was picked, what the alternatives were, why you made the build/buy decision, and more as mentioned in the previous comment.

        Without answering the questions, the presentation would not be useful for the audience at The Fifth Elephant, since it reads like documentation and doesnt not talk about the journey in picking this solution, which is what is valuable for the audience.

        Do take the time till June 17 to work on your slides and update them. Meanwhile, we’d also need a preview video. The video is a 2 min self recorded video, where you talk about the problem you’re trying to solve and what you’d be covering in your talk.

    Marked as rejected since the proposer hasnt responded & slides are not accessible. Will be considered for a future conference if the content is updated.
