Associate Software Development Engineer 2
Publicis Sapient
- Owned and evolved a regulated GCP banking platform serving 25M+ customers across Goals, Priority Banking, Challenges, and Pensions Hub, enabling 50+ microservices across 10+ engineering teams through a cloud-native stack built on Kubernetes, Istio, Terraform, Apigee, Kafka, Dataflow, BigQuery, and Cloud Spanner.
- Consolidated multiple Kubernetes environments into a shared platform with Istio service mesh, reducing operational overhead and lowering annual infrastructure costs by $30K+.
- Built a real-time event-driven data platform using Cloud Spanner, Confluent Kafka, and BigQuery, supporting 10+ downstream services and processing thousands of billing lifecycle events to enable real-time customer communications and operational analytics.
- Developed a cloud-native rewards platform supporting 1M+ participant registrations, orchestrating eligibility evaluation across millions of customer records and automating winner selection for campaigns running up to 30 days using Dataflow, Composer, Cloud SQL, and GKE.
- Delivered an AI-powered SIC code classification engine that improved prediction accuracy from 72% to 94% and eliminated 40+ hours of manual effort per week; co-developed an enterprise RAG platform that reduced knowledge discovery time by approximately 80%.
Associate Software Development Engineer 1
Publicis Sapient
- Launched and operated an enterprise API platform using Apigee and Akamai CDN for 12+ services, implementing authentication, rate limiting, traffic management, and API versioning while reducing API latency by approximately 35%.
- Established end-to-end observability using Dynatrace, distributed tracing, centralized logging, and proactive alerting, enabling platform- wide visibility and maintaining 100% target SLO compliance with zero unplanned production downtime over 6 months.
- Architected and provisioned a multi-region Cloud Spanner deployment spanning three regions and six replicas for 7M+ customers, maintaining sub-millisecond regional reads and sub-50ms query performance while implementing PITR capabilities and performance optimizations that improved throughput by 20%.
- Brought an API platform (Apigee + Akamai CDN) online for 12+ services, with auth, rate limiting, and versioning baked in, shaving API latency by ~35% and improving the overall security and compliance posture across all connected services.
- Standardized Terraform modules, deployment patterns, and CI/ CD practices across 15+ teams and 50+ engineers, reducing onboarding time from four weeks to one week and improving deployment reliability through automated validation and rollback mechanisms.
Projects
