Senior Frontend Developer for SaaS Platform

@rajat07me

Hi, this is a very interesting SaaS build and the brief is detailed enough to see the complexity clearly. I have solid experience with complex frontend applications, modular dashboards, API-heavy interfaces, and editor-based workflows in React/Vue environments. The nested rule logic, versioning, team sharing, and real-time validation pieces are the parts that need careful architecture from day one, and that is where I can help well. I can start immediately and build this in structured phases so the platform stays scalable as features expand. Happy to discuss the preferred stack and editor approach through the platform.

Hi there, I can help build the frontend for your SaaS dashboard with a practical focus on maintainability, clear workflows, and a smooth rule-authoring experience. My background includes complex React/TypeScript web applications, SaaS workflows, REST API integration, and data-heavy interfaces where state structure and usability matter as much as the UI itself. For this project, I would suggest a React + TypeScript approach unless your team has a strong Vue preference. It fits well for a modular dashboard, Monaco or CodeMirror integration, reusable template-management screens, and robust handling of nested Schematron rule data. I would keep the architecture straightforward: well-defined editor state, predictable validation/API boundaries, reusable UI components, and automated tests around the critical rule editing, versioning, and sharing flows. The key risk I would manage early is the editor experience: XML/Schematron authoring needs fast feedback, readable errors, and safe editing without making the interface too complex. I would start by aligning on the rule data model, validation API contracts, and the minimum useful editing workflow, then expand into cloning, versioning, permissions, and team sharing. I’d be happy to review your current backend/API status and discuss the simplest implementation path for a reliable first production version.

@Hammadhassan21

Hey there, The challenging part of this SaaS dashboard is the Schematron editor, especially keeping deeply nested XML/XPath rule structures understandable while users create, edit, version, and validate them. I can work with React or Vue 3 and TypeScript, building the dashboard around a structured state model and integrating a web editor such as Monaco or CodeMirror. The frontend can connect cleanly to your REST/GraphQL APIs for validation and template workflows, while keeping the UI modular enough for the later sharing, permissions, and versioning phases. The phased 4 6 month roadmap makes sense for this type of product, particularly separating the editor foundation from collaboration and validation features. Do you already have an API specification and a preferred choice between React and Vue 3? Best regards, Hammad Hassan
