**Workplace:** remote

## Description

We’re looking for a Senior Fullstack Developer - Freelancer

### **  
What We’re Looking For**

-   **A Full-Stack Craftsman:** You are an expert in **Ruby on Rails and TypeScript**, capable of building everything from complex dashboards and billing UIs to sleek documentation platforms.
-   **The "DevEx" Champion:** You have a natural empathy for other developers. You’ll develop deep knowledge of our platform (Pub/Sub, Chat, LiveSync) and use the product yourself to gain a first-hand understanding of the developer experience.
-   **Comfortable with Ambiguity:** You thrive in high-level vagueness. You can take a feature from a loose concept to a shipped product with minimal hand-holding, identifying problems and proposing solutions independently rather than waiting for a roadmap.
-   **Accountable & Reliable:** You take pride in high-quality, well-tested code. You meet your delivery commitments, provide realistic estimates based on technical complexity, and communicate proactively if a timeline is ever at risk.
-   **An Owner:** You monitor what you build in production and take personal ownership of quality issues. You see a feature through its entire lifecycle, from the first line of code to the final metric.
