I've architected high-volume backend systems at Squadra Media, including an AWS SQS reporting pipeline that processes over 2 million records per report, OpenSearch-powered retrieval, HLS video transcoding, and GDPR-compliant PII deletion workflows for 25,000+ users.
I've also migrated legacy Node.js/GraphQL systems to TypeScript/REST APIs, built backend architecture for a multi-platform startup ecosystem, delivered six native Android MVPs in three months, and developed real-time multiplayer betting systems using WebSockets and MySQL.
