## About

```text
At SMC Finance, I designed and shipped a configuration-driven workflow engine for a multi-stage loan origination pipeline, so business teams can change stage flows and validation rules without code changes or releases.

I also engineered the underwriting decisioning engine and built a GCP Pub/Sub microservice that automated collateral initiation workflows with fault-tolerant message delivery. I designed REST APIs for loan origination and maintained 90% Jest coverage across critical financial modules.

As a freelance backend engineer for a live social video platform, I built a Go streaming server for RTMP ingest, FFmpeg transcoding, and HLS delivery. I also implemented WebRTC signalling and call-state management for multi-party sessions.

On LifeBoard, I co-built the product and led backend design, including per-user envelope encryption with Cloud KMS and a migration of media from MongoDB to Cloud Storage without downtime. My work spans distributed systems, financial infrastructure, and real-time streaming.
