Daniel Song

I am a hands-on senior software engineer focused on building highly scalable full-stack systems and performance-critical backend services using TypeScript, Node.js, Python, and cloud platforms such as Azure and AWS. I design modular cloud architectures, event-driven workflows, and resilient data pipelines that improve throughput, latency, and reliability across global environments.

I have delivered production-grade distributed platforms at large enterprises and startups, including telemetry ingestion, async orchestration, schema-driven validation, and observability-led debugging. My work has reduced API breakage, stabilized spikes with durable retry patterns, and produced measurable improvements in p99 and median latency through caching, batching, and worker-thread offloading.

I prioritize secure, test-first delivery: I implement contract testing, multi-environment integration matrices, CI/CD automation, and hardened auth flows to maintain compliance and minimize incidents. I also build intuitive front-end experiences with React/Next.js and bridge client-server schema evolution to keep UIs consistent during rapid change.
