  • Company Overview: Iterable is a cross-channel platform that provides unified customer experiences and makes it easier for marketers to create, optimize, and measure relevant customer interactions.
  • Led innovation initiatives under the company's Nova AI vision, including architecting a beta solution for natural language query translation using AWS Bedrock and LLMs, rolled out to 100 customers and positioned to secure $600K in AWS credits.
  • Designed and executed Retrieval-Augmented Generation (RAG) and agentic AI capabilities for intelligent asset discovery, enhancing content and catalog intelligence through natural language-driven personalization, leveraging S3, distributed indexing.
  • Drove platform modernization by re-architecting legacy Angular frontends into modular React applications with GraphQL APIs, Scala services, and PostgreSQL optimizations, enhancing performance across campaign templates, editors, and image tracking.
  • Refactored legacy code, implemented reusable components, and eliminated 100% of critical security vulnerabilities.
  • Designed scalable pipelines that improved system reliability and maintainability across 1,400+ enterprise clients.
  • Resolved a long-standing reliability issue in Elasticsearch segmentation queries by collaborating with key stakeholders to design a phased optimization strategy. Achieved up to 90% performance improvement across 7M+ custom fields across all the users by implementing distributed caching, cardinality tracking, conditional regex, indexing strategies, and smart query constraints.
  • Led the re-architecture of Angular frontends into modular React with GraphQL APIs, migrating away from third-party dependencies, addressing security vulnerabilities, and improving performance, maintainability, and team velocity.
  • Implemented secure, distributed API infrastructure with Zero Trust authentication using scoped tokens and IAM.
  • Delivered long-term improvements to catalog performance using a multi-cache using distributed caching layer(Redis), reducing latency and offloading overloaded systems.
  • Designed and implemented event-driven infrastructure for Journeys, catalog orchestration, and personalization workflows, enabling near real-time data sync and scalable user experience orchestration based on live behavioral insights, with Elasticsearch-backed access to millions of segmentation lists per customer.
  • For enterprise customers like Athletics and Grammarly, designed the strategic roadmap for Catalog Segmentation and Dynamic Lists, evolving toward full Catalog Orchestration through Journeys to deliver near real-time, event-driven personalization at scale.
  • Established a standardized architectural framework adopted across engineering teams, incorporating long-term thinking and well-defined RFC designs, validated through stakeholder alignment and approved prior to implementation sign-off.
  • Spearheaded key initiatives by working closely with tech leads and engineers to align short-term solutions on escalations with long-term architectural direction. Established a standardized architectural framework adopted across teams and approved by multiple stakeholders before sign-off.
  • Streamlined the GDPR compliance pipeline by optimizing API overload with S3, Kafka, and queue-based architecture. Analyzed and segmented issues into distinct use cases, proposing targeted enhancements to the forget endpoint. Mitigated $50M+ in risk by implementing resilient suppression logic and a distributed architecture tailored to support real-time compliance at scale.
  • Drove performance awareness and cross-team alignment by standardizing benchmarking practices and setting clear benchmarks for catalog scalability. Streamlined engineering processes, improved cross-org collaboration, and enhanced customer trust through consistent communication and delivery.
  • Iterable is a cross-channel platform that provides unified customer experiences and makes it easier for marketers to create, optimize, and measure relevant customer interactions.
