DESIGN AUTOMATION

Design Automation Platform – Serverless E-Commerce Publishing

Serverless event-driven platform that cut end-to-end processing time by 90% and eliminated manual bottlenecks

Challenge

  • •End-to-end cycle times measured in days, with multiple manual handoffs between stages
  • •High rework rates (30-40%) due to quality issues detected too late in the pipeline
  • •Fragmented toolchain with no integration between production, publishing, and inventory systems
  • •No scalable infrastructure to handle demand spikes or batch operations

Solution

  • •Designed a modular, event-driven processing pipeline with discrete stages for generation, validation, transformation, and publishing
  • •Built an automated quality gate that validates outputs against configurable rules before promotion to the next stage
  • •Implemented batch processing with SQS-backed worker Lambdas for parallel execution at scale
  • •Created a versioned asset store with searchable metadata and reuse tracking to accelerate future runs
  • •Architected a serverless backend with Next.js frontend, API Gateway to Lambda (FastAPI), SQS + worker Lambda, DynamoDB for state, S3 for assets
  • •Shipped with AWS CDK + GitHub Actions for multi-env IaC (dev, staging, prod), feature flags, and canary releases

Impact

  • •90% reduction in end-to-end cycle time (from days to under one hour)
  • •Rework rate dropped from 30-40% to under 15% through automated quality gates
  • •8x throughput increase with no additional headcount
  • •Reusable infrastructure blueprint now applied to two additional product lines
  • •Operating cost per unit decreased by over 60%
