Key Contributions

  1. Reward and Voucher Service

    • Architecting a highly scalable, fault-tolerant service using an event-based architecture to manage all platform-wide rewards.
    • Building the complex logic for a high-throughput order book to handle all reward and voucher transactions.
    • Developing a secure user wallet system for managing user balances and other digital assets.
    • Integrating with multiple payment gateways to ensure seamless and reliable transactions for users.

  2. Criczop

    • Lead backend architecture and optimizations to handle massive, concurrent user loads. Achieved and maintained a 20ms P99 latency through strategic API and database query tuning.
    • Built the low latency streaming pipeline for broadcasting live match updates to all connected users. Used Server Sent Events (SSE) with a pub/sub system to achieve ~20ms broadcast latency.
    • Built a creative system using LLMs to rephrase match commentary and feed into multiple tones delivering a unique, personalized feature to deepen user engagement.
    • Developed a self-contained, embeddable widget for third-party sites to display live cricket feed and content. Ensured low latency (~20ms) broadcast of match events and cricket content to this widget. Created a new B2B distribution channel and expanded the platform’s reach.
    • Build a custom, fault-tolerant job processing library using Elixir/OTP specifically to support platform needs. Designed for fault tolerance, achieving a sub-10ms RPC latency and horizontal scalability on Kubernetes.

  3. CMS Service

    • Led the full development cycle of the CMS using Payload and MongoDB.
    • Collaborated closely with product, marketing, and content teams to align the technical architecture with business goals.
    • Enabled non-technical teams to manage and deploy content independently, reducing engineering overhead.

  4. Misc

    • Account Service: Integreated Google Recaptcha to protect critical endpoints from bot-based abuse.
    • Observeability: Strengthened the observeability stack by integrated OpenTelemetry + SigNoz (self hosted), significantly reducing reliance on expensive monitoring tool like Datadog.
    • Quizzop: Iplemented geofencing logic to manage location-based access to quizzes and platform features.
