DevConfig-Gen

Provider-Driven Engine

A provider-driven engine that turns structured JSON/YAML into validated, deterministic configuration. A single tiny provider contract is the only extension point — domain transforms and even WebUI field rendering stay pluggable, with zero runtime dependencies.

  • Single extension point: the provider contract
  • Full-chain pluggable, incl. WebUI widget registry
  • Deep merging with path-specific --set overrides
  • Strict schema validation & path-level diagnostics
  • Unified CLI, wizard, Web UI, and Python API
  • Deterministic output · zero external runtime dependencies

What I Work On

I focus on developer tooling, system automation, and configuration management. I enjoy taking repetitive, error-prone setup tasks and turning them into clean, reliable pipelines that are straightforward to test and maintain.

I build practical tools for everyday developer workflows — focusing on zero runtime overhead and predictable behavior. I value readable code, good test coverage, and clear documentation that helps people solve problems quickly.
