Moshe Uminer is a Senior Software Engineer in New York with seven years of full-stack and data engineering experience, fluent in Python, TypeScript, Dart/Flutter, and Rust. He drives performance and developer-experience improvements—e.g., migrating a matchmaking stack to Postgres/Drizzle and OpenAPI to cut common operation times from ~1s to ~10ms. Moshe contributes across the stack in open source, adding UI primitives and interactive gestures to SolidJS projects and maintaining backend APIs for the embeddable SirixDB bitemporal database. He has a track record of rescuing stalled projects, building CI/test suites, and removing classes of bugs through architecture and tooling changes. Comfortable in both backend data pipelines (Airflow, data-quality tooling) and polished client apps, he blends hands-on implementation with setting standards and guardrails to accelerate reliable delivery.
