• Design & build the TS extension framework: execution model, SDK ergonomics, sandboxing, versioning, and testing strategy.
• Create developer tooling in .NET 8: command-line tools, MSBuild tasks, project templates, code generation, and packaging/publishing flows.
• Ship a delightful dev experience: local dev loop, hot-reload/test harnesses, clear error messages, docs and samples.
• Harden the pipeline: schema validation (YAML/JSON), OpenAPI generation/consumption, provenance, and reproducible builds in Docker/CI.
• Own the roadmap with the team: discovery ? implementation ? release.
• Work across the stack where useful (e.g., Node runtime, SQLite/MSSQL adapters, REST/gRPC).

• TypeScript extension(s) and UI devtools for our application development platform.
• Robust C#/.NET (build) tooling (CLIs, analysers, CI integrations) that compiles, validates and packages configurations into deployable artifacts.

• TypeScript/Node 20+ (runtime, SDKs, generators)
• NET 8 / C# (CLI tools, analyzers, MSBuild)
• YAML/JSON (Schema, Rules and Configuration), OpenAPI, SQL
• Docker (local + CI)
• (Nice) VueJS exposure for the platform UI/devtools
