Email: dmitry@thaler.dev

Senior full-stack engineer with a backend focus and 15+ years of experience. Most of my work is at the integration layer: bringing awkward external systems together behind GraphQL and REST APIs that product teams can rely on. This has included payment gateways and government services at a national lottery, multi-protocol network telemetry, and retail planning systems processing billions of sales and inventory records.

I take ownership beyond the application code, including infrastructure, deployment, and observability. I care about keeping systems reliable and cloud costs under control.
