I'm an Engineer passionate about building reliable, scalable, and developer-friendly systems — from microservices to serverless architectures, from infra automation to real-time apps.
I love designing systems that bridge product velocity and infrastructure reliability, with a strong focus on DX, observability, security, and clean architecture.
- Backend development using TypeScript/Node.js, .NET, Hono, tRPC, and event-driven patterns
- Cloud architecture (AWS) with SST, Lambda, DynamoDB, EventBridge, IoT Core, RDS/Postgres
- CI/CD & DevOps — GitHub Actions, IaC, Terraform, Helm, Kubernetes, GitOps (ArgoCD)
- Real-time systems using WebSockets, MQTT, SST Realtime, and scalable pub/sub
- Product-first engineering: metrics, observability, API quality, and developer experience
- Speaker — WarsawJS #131 “How to Build Serious Infra Without Losing Your Sanity (feat. SST)” Live demo using SST Realtime, AWS IoT, and Next.js.
