I’m a Senior Backend Engineer with 5+ years of software development experience specializing in AWS serverless architecture and event-driven microservices. I focus on turning monolithic systems into scalable, cost-effective solutions using Domain-Driven Design principles.

At SkyAlert, I led a gradual refactor from monolithic services to serverless event-driven microservices, defining subdomains and bounded contexts. This work improved scalability and reduced response time by 50% while cutting operational costs by 30%.

I redesigned an earthquake alert delivery service by introducing SQS delayed queues to prioritize critical life-safety notifications. I also migrated performance-critical Lambda functions from TypeScript to Go, reducing cold start times by 70% and improving alert processing latency.

I architected and built an IoT device application in Go for Raspberry Pi deployment, replacing an over-engineered Node.js approach with a single-binary solution and MQTT connectivity to AWS IoT Core. I use AWS CDK and GitHub Actions for CI/CD, and I’ve boosted delivery speed with an AI-assisted workflow using Kiro CLI to generate infrastructure from PlantUML, AsyncAPI/OpenAPI, and database schemas.
