Multi-Region Failover with Amazon API Gateway
High availability is critical for modern applications, especially when serving global users.
I build the backend that holds everything together.
Distributed systems, data pipelines, and the APIs beneath them: the parts of a product you can't screenshot. One of them is drawn below.
0k+Pass Gallery, 2025 · per migration run
< 0hdown from a multi-day manual process
Backend systems I've built in production, most recent first. The lead piece is a full teardown; the rest give the shape and the stack.
Pass Gallery migration
A resumable, distributed pipeline that moves 500k+ images per client between gallery platforms in under 24 hours. It preserves folder structure and metadata, and recovers from mid-run failure without restarting the whole job.
Paismo: Nexus API & HRMS backend
A multi-tenant HRMS backend and public workforce API covering payroll, time & attendance, leave, and document generation, with bi-directional accounting sync.
Furniture Clinic data pipelines
Automated ingestion of 30,000+ Amazon orders per month, pulled from Seller Central and the Advertising API into a unified MongoDB store that feeds live Power BI reporting.
Field notes from production: what held, and what broke.
