I’m looking for an experienced developer to help further build and professionalize IN1, a modular multi-tenant SaaS platform built with Lovable, including code in React, TypeScript++, connected with, Git, and Supabase. The platform consists of several connected business modules (CRM, HR, Learn, Meet, Sign, etc.) powered by a shared Core system for authentication, tenants, permissions, and integrations. I need support with improving the technical architecture, especially around authentication flows, Core integration, and sync/event communication between modules. Some parts are already working well, but we want to make the system more robust, scalable, and easier to maintain as we grow. We also want to significantly upgrade the UI/UX and visual design. We are not looking for a generic AI-template style, but a custom, premium, modern product experience. We can provide sketches/wireframes in tools like Figma. In short, I’m looking for someone who can combine strong frontend skills with architecture thinking, help stabilize the platform, modernize the product experience, and support long-term development across the ecosystem.

Is Core already the single source of truth for tenant/role/auth across every module, or are CRM, HR, Learn, Meet, and Sign still carrying some of their own logic? That is usually where multi-tenant SaaS starts getting messy. I can help you harden IN1 in a way that scales: • Audit the current Core → module flow and remove duplicated auth/permission logic • Standardize tenant context, claims, and session handling in Supabase • Build a cleaner sync layer for module communication so updates move through events instead of brittle direct coupling • Tighten the React/TypeScript codebase for maintainability and long-term growth • Upgrade the UI/UX into a custom, premium product system from your Figma sketches, not a generic template look Relevant work: • Fledger — UK financial platform where structure, permissions, and reliability mattered • iTourAI — React/Node/MongoDB product with complex multi-screen flows and cross-platform delivery • Traders Hub — improved the UI/UX of a live trading website to feel more polished and product-ready My focus would be to make IN1 easier to extend, safer to maintain, and much stronger visually across the whole ecosystem. If you share the current Core flow and one or two key screens, I can tell you exactly where I would start—do you want me to focus first on architecture or the UI system? ~Rajesh

Hi I can support you in stabilising and scaling IN1 while elevating the product experience to a more refined, production-grade SaaS platform. My focus would be on tightening the architecture—especially authentication flows, tenant isolation, and Core-module communication—ensuring reliable event handling and clean, maintainable patterns across your React/TypeScript and Supabase stack. On the frontend, I’ll help translate your Figma sketches into a cohesive, premium UI system with consistent components, improved UX flows, and a polished, modern feel—avoiding generic templates. I approach projects like this with a long-term mindset: clean structure, clear boundaries between modules, and scalable patterns that support growth. I’m comfortable working iteratively, aligning closely with your vision while improving both performance and developer experience across the platform.

Hello, I can support you on both fronts, stabilizing and scaling the technical architecture while elevating the UI/UX into a premium, product-grade experience. On the architecture side, I’ll focus on refining authentication flows, strengthening your core (tenants, permissions, and integrations), and introducing a clean, event-driven communication layer between modules to improve reliability and scalability. The goal is to reduce coupling, improve maintainability, and ensure each module (CRM, HR, Learn, etc.) can evolve independently without breaking the ecosystem. On the frontend, I’ll translate your Figma wireframes into a polished React/TypeScript interface clean, fast, and consistent across modules. No generic templates; this will feel like a cohesive SaaS product with thoughtful UX, clear hierarchy, and smooth interactions. What I’ll deliver: – Improved system architecture with clearer module boundaries – Robust auth + Core integration flows – Scalable communication patterns between services/modules – Modern, high-end UI aligned with your product vision – Clean, maintainable React/TypeScript codebase I’m comfortable working within your current stack (Lovable, Supabase, and Git) and contributing as a long-term technical partner as the platform grows. Happy to start with a focused phase (audit + key improvements) and build from there. Regards, Moiz

Hi, I understand IN1 is already beyond MVP stage and the real challenge now is strengthening the shared Core architecture so the individual modules can scale without becoming tightly coupled or difficult to maintain. The important part is making authentication, tenant isolation, permissions, and inter-module communication predictable while also improving the frontend experience so the platform feels like a polished product rather than a collection of tools. For IN1, I’d focus first on stabilizing the Core layer—tenant-aware auth flows, permission boundaries, event-driven communication, and shared state management between modules. With Supabase involved, I’d likely introduce clearer service abstraction and typed contracts between the frontend and backend so modules stay independent but synchronized. On the UI side, I’d move toward a stronger design system with reusable components, better hierarchy, smoother transitions, and a more premium interaction model rather than generic dashboard styling. One area I’d want to review early is how modules currently communicate and where business logic is duplicated, since those decisions usually determine future scalability more than the framework itself. Once that structure is cleaned up, the platform becomes much easier to evolve long term. Thanks, Denis.

I can deliver this work in 2 weeks with a budget in the $250–300 range, focused on stabilizing authentication flows, improving Core integration, and making module communication more reliable as the platform grows. To get started, I would just need access to the repository, a quick overview of the current auth/Core flow, and your Figma sketches or wireframes so I can align the architecture and UI improvements from day one. I’ve worked on modular platforms where shared services manage authentication, permissions, and communication across multiple modules. In one project, I implemented structured APIs and role-based systems designed to support long-term product growth and maintainability. My focus would be to review the current architecture, strengthen auth and module communication, and refine the React component structure so the system stays stable as the platform evolves. Happy to review your current architecture and outline the first set of improvements to get started.

Hi, I can help you stabilize and scale IN1 into a clean multi-tenant SaaS architecture with a premium, non-template UI and a more reliable Core system. You need stronger auth flows, module communication and a consistent UX across CRM, HR and other services, and I’ve worked on full stack React + TypeScript systems with Supabase where multi-module structure and role-based access had to stay tightly synchronized. I’ll focus on strengthening your Core layer (auth, tenants, permissions), improving event/sync patterns between modules, and refining the UI into a cohesive product experience driven by your Figma direction. What’s currently the weakest point in your system: authentication consistency, cross-module syncing, or UI structure? Best Regards, Fizza Nadeem K
