Demi Daniel

Hi, I'm Demi.

I'm an operations-focused full stack developer who works across product surfaces, APIs, data flows, and production environments. My experience spans Angular and React UIs, Java/Spring and .NET services, PostgreSQL, SQL Server, AWS, and the operational work needed to keep systems reliable.

A lot of my work is support under real constraints: triaging P0-P3 incidents, reading application and route logs, validating APIs and batch endpoints, and tracing issues from UI behavior through services and databases.

I care about data safety and durable fixes. That means peer-reviewed SQL, row-count checks, narrow predicates, rollback plans, evidence-based RCA, runbooks, and guardrails that reduce repeat incidents.
