Responsibilities

Ship features end-to-end across React/TypeScript and .NET Core, from first sketch to production.
Help shape our new multi-location inventory app, architecture, data model, UX trade-offs, all of it.
Push the no-code engine forward, designing the primitives that let non-developers build serious apps.
Pair with AI tools (Claude, Copilot, Codex) as part of your daily workflow, with the judgment to own what you ship.
Trade ideas with a team that genuinely argues trade-offs in code reviews, not one that rubber-stamps PRs.
Assist in mentoring and coaching for junior and intermediate developers.
