  • Architected Centralized Reporting Platform: Designed and built a unified reporting solution aggregating
    data from Redshift, Athena, and RDS across multiple AWS accounts. Successfully drove adoption across 10+
    internal teams, unifying business insights and reducing data silos.
  • API Design & Security: Engineered secure, scalable APIs with granular IAM authentication, enabling
    downstream analytics teams to programmatically ingest CSV reports, enhancing data accessibility and security
    compliance.
  • Infrastructure as Code (IaC) Leadership: Led the migration to automated infrastructure by implementing
    AWS CDK projects. This initiative eliminated manual resource provisioning errors and established a consistent,

  • Platform Engineering & Developer Productivity: Conceptualized and implemented a reusable
    Function-as-a-Service (FaaS) library. Delivered complete HLD/LLD documentation, which simplified microservice
    deployments and reduced boilerplate code for multiple development teams.
  • Performance Optimization at Scale: Re-architected the storage backend by replacing PostgreSQL with AWS
    S3. This strategic pivot removed connection bottlenecks, enabled horizontal pod scaling, and halved data read
    times, significantly boosting throughput.
  • Data Pipeline Architecture: Engineered Proof of Concepts (POCs) for high-volume Snowflake-to-S3 data
    transfers using Python/PySpark and Native Snowflake Pipes. Provided comparative analysis to stakeholders to
    select the optimal production rollout strategy.Location: Bangalore, India
