Aayushi Gupta

I’m a backend engineer with around 3 years building and owning production distributed systems across payments, fintech, and cloud-native platforms. I led zero-downtime AWS multi-region migration serving 1M+ customers and architected event-driven data workflows spanning multiple microservices.

At Amazon, I led zero-downtime migration of 2 production services from DUB to ZAZ AWS region, driving end-to-end system design, infrastructure setup, deployment automation, and migration of 10L+ customers. I engineered controlled traffic cutover with a data consistency strategy (per-tenant validation and zero-data-loss verification) and used CloudWatch monitoring to ensure high availability, fault tolerance, and production stability. I also owned an on-demand customer data deletion system using event-driven architecture (SNS–SQS) and Infrastructure-as-Code, enabling compliant deletion across 3+ microservices with idempotency, monitoring, and fault tolerance.

Previously at Pine Labs, I designed and built a distributed link generation service, owned zero-downtime migration of (1M+) links from a Branch.io, and integrated five payment gateways into the core payments platform. At Niyo Solutions, I built backend modules for a federal credit card system and engineered a real-time data pipeline using Kafka and Elasticsearch for sub-second search and analytics, while mentoring through code reviews. I’m also AWS Certified Solutions Architect and have built LLM-powered applications using Python, LangChain, and Hugging Face for RAG workflows.
