Isaac Hwang
@isaachwang
I am a Senior Software Engineer specializing in scalable backend systems.
United StatesWhat I'm looking for
I build and architect scalable backend services and APIs for high-impact, user-facing platforms, improving code maintainability and delivery velocity. I designed NestJS-based services supporting 50,000+ active users, integrated GraphQL and TypeORM to speed complex queries, and orchestrated over 2 million monthly background tasks using RabbitMQ while optimizing CI/CD with Docker, Kubernetes, and Azure DevOps.
Earlier, I developed core .NET Core services for large-scale collaboration products, improved authorization with OAuth2 and RBAC, refactored monoliths into microservices on AKS, and mentored engineers through code reviews and knowledge sharing. I prioritize observability and reliability—implementing Prometheus and Grafana to cut incident response times and deliver performant, maintainable solutions in Agile teams.
