CRM SaaS platform built on Laravel + Blade + [login to view URL] + Tailwind CSS, with authentication, a database, and core infrastructure already live in production. We've had a full frontend prototype built out separately — a single interactive HTML file ([login to view URL] + Tailwind CSS) covering several major feature areas of the product, all fully clickable and functional against local browser storage. We now need a Laravel developer to wire this prototype into our real backend: real database tables, real API endpoints, real authentication, and real permission enforcement. This is not a from-scratch build. The UI, UX, and interaction logic already exist and work. The job is backend integration — designing the database schema, building the API, and connecting the two. Why This Should Be Faster Than a Typical Integration The prototype was deliberately built to minimize this exact handoff: Same frontend stack as production — [login to view URL] + Tailwind CSS throughout (one exception noted below), so there's no framework to port. Every feature's data access already goes through a single, isolated "data layer" object ([login to view URL](), [login to view URL](), etc.) instead of being scattered through the UI code. Swapping the inside of each method from localStorage to a real fetch() call is a contained, mechanical change — the UI code calling it doesn't need to change. Every data field is already snake_case and shaped to map cleanly onto database columns (e.g. company_name, logo_url, quote_number, unsubscribe_message). The intended API contract is documented directly in code comments above each data-layer resource — expected routes, HTTP verbs, and response shapes are already spelled out. Config objects already have placeholders for auth context (csrfToken, currentUser) on every component, matching the pattern our real app already uses elsewhere — ready for real values to be injected via Blade. What's Already Built in the Prototype Branding & Email Signatures — company branding settings (supports multiple saved brand profiles), a multi-step email signature builder with several templates, save/reuse/delete flows Quotes — full quote builder with line items, tax, product features list, notes, terms, PDF-style export/preview, and the ability to apply a saved brand's logo/name/color to a quote Contacts — People and Companies list views with a shared tab layout Omnichannel Inbox — multi-channel conversation view, plus a channel-connection wizard (WhatsApp/Meta/SMS/LinkedIn-style flows, currently simulated) Teams & Permissions — team/user management and a custom permission-rule system currently enforced client-side only Email Marketing — campaign dashboard with charts, campaign CRUD, a block-based drag-and-drop email designer plus raw HTML mode, a template library, audience filtering/segmentation, CSV import/export, scheduling/send controls, and per-campaign tracking + reporting Social Media — post templates, a content calendar, and a media library Forms Reports — stats derived from forms created in the Forms builder Scope of Work Database schema — design and migrate real tables for each resource above (quotes, campaigns, contacts, teams, permission sets, etc.), matching the field names already used in the prototype where reasonable. API layer — build Laravel routes/controllers matching the documented contract in the data-layer comments (mostly straightforward REST: index/store/update/destroy per resource). Wire the data layer — replace the inside of each dataLayer.* method with real fetch() calls against the new endpoints. This is the main "connect the two" step. Real authentication & account scoping — every request needs to be scoped to the logged-in user/account; wire in real CSRF tokens and user context where the prototype has placeholders. Server-side permission enforcement — the custom permission-rules system currently only hides/shows UI elements client-side. This needs to become real Laravel Policies/Gates so it can't be bypassed via direct API calls. (The client-side rule logic and its evaluation order are documented in a code comment and can be used as the spec.) Real file uploads — logos, signature photos, and media library images currently store base64 data directly; these need to become real multipart uploads to storage (S3 or local disk) returning a URL. QA against the existing prototype behavior — the prototype is the source of truth for expected UI behavior; the goal is matching functionality with real data underneath, not redesigning anything. Explicitly Out of Scope (flag separately if interested) Real email sending infrastructure (SMTP/SendGrid/etc. integration) for the Email Marketing module — currently simulated Real OAuth integration with WhatsApp/Meta/LinkedIn/Twilio for the Omnichannel channel connections — currently simulated Real-time updates (websockets) for the Omnichannel inbox The Forms builder is built in React rather than Alpine — decide whether to keep it as an embedded React component or port it Requirements Strong, demonstrable experience with Laravel (routing, Eloquent, migrations, Policies/Gates, API resources) Comfortable working with [login to view URL] and Tailwind CSS on the frontend side Experience designing REST APIs and relational database schemas from an existing frontend Able to read and follow existing code conventions rather than rewriting things to personal preference Bonus: experience with file upload/storage handling in Laravel, and with implementing row-level or role-based permission systems Deliverables Database migrations for all in-scope resources Laravel API routes/controllers per the documented contract Updated dataLayer methods pointing at real endpoints (frontend file provided) Working authentication/account scoping across all endpoints Server-side permission enforcement matching the documented rule set Real file upload handling replacing base64 storage Brief written notes on any deviations from the original contract, for our own records

Your prototype setup is ideal for a smooth backend integration since the data layer and API contract are clearly defined. I’ll start by designing the database schema closely aligned with the snake_case fields from your prototype, minimizing surprises and ensuring a clean match. Next, I’ll build Laravel REST routes and controllers as documented. For authentication and account scoping, I’ll wire in Laravel’s built-in systems plus CSRF tokens so all requests are secure and user-specific. The permission rules client-side logic will be transformed into Laravel Policies and Gates to enforce rules securely server-side, blocking any direct bypass attempts. Regarding file uploads, switching from base64 to multipart uploads will solve storage scaling and bandwidth issues while generating accessible URLs for media assets. Would you prefer using local storage or S3 for file handling? Since the frontend already isolates data calls in the dataLayer object, I’ll replace localStorage code with real fetch requests to the new API, ensuring the UI behaves exactly as the prototype shows. This setup lets us complete integration without changing UX or UI logic. I’ve done similar Laravel API integrations with frontend prototypes for SaaS apps, where syncing the data layer like this saved time and avoided regressions. Let’s get started turning your prototype into a full backend-powered app. Just send me the dataLayer file and any existing schema notes when you’re ready.

Hi, I've read the full scope carefully. The architecture here is smart — isolating all data access behind a single dataLayer.* object means this integration is mechanical rather than exploratory. Swapping localStorage calls for real fetch() against Laravel endpoints, while keeping the UI untouched, is exactly the kind of backend wiring I do well. My approach: Schema design — migrate tables matching the snake_case field names already in the prototype (quotes, campaigns, contacts, teams, permission_sets, etc.), with proper account-scoping foreign keys from day one API layer — Laravel routes/controllers following the documented contract in the data-layer comments. Index/store/update/destroy per resource, API Resources for response shaping Data layer wiring — replace each dataLayer.* method internals with real fetch() calls. CSRF tokens and currentUser injected via Blade into the existing config placeholders Server-side permissions — convert the client-side rule logic (documented in code comments) directly into Laravel Policies/Gates. No UI-only enforcement File uploads — multipart upload endpoints returning URLs, replacing base64 storage. S3 or local disk depending on your current setup I follow existing code conventions — I'm not here to rewrite your architecture. One question: is the Forms builder React component currently embedded via a Blade component or as a standalone iframe/bundle? Farhan Technical PM & IT Strategist

Hello, The prototype’s isolated data layer should make the Laravel integration cleaner than rebuilding each frontend feature. I would map the documented contracts to tenant-aware migrations, models, validation, policies, and REST endpoints. The selected modules would then be moved from localStorage to authenticated backend requests and tested end to end in the production structure. Because the listed feature areas are broad, I suggest defining a focused first phase and completing its priority modules properly before expanding the remaining areas. This keeps data ownership and permission enforcement consistent instead of partially connecting every module. Does the production application already have an organization or tenant model and an authorization package in place? Which modules must be fully operational in the first phase: branding, quotes, contacts, or another priority? Are real WhatsApp, Meta, SMS, email, and social integrations included now, or should this phase only persist the currently simulated workflows? Best regards, Albert C.

A STRONG SAAS BACKEND NEEDS TO TURN GOOD UI INTO RELIABLE BUSINESS LOGIC. Hello, my name is Jonas, full stack developer. The difficult part here is not connecting the screens, but making sure the real backend follows the same behavior while keeping data secure. I suggest mapping the existing prototype contracts into Laravel resources, then replacing the browser storage layer with real APIs step by step. The database structure will be designed around the existing fields so the frontend integration stays clean. I will build the REST endpoints, authentication flow, and server-side permissions using Laravel standards. I have worked with Laravel, REST APIs, SaaS applications, and database-driven platforms with custom dashboards. File handling will be moved from base64 storage into proper uploads with managed storage paths. The final system will be tested against the prototype so the real data flow matches what users already expect. Quick one, is the current Laravel authentication already using a package like Laravel Sanctum, or should the API authentication layer be added as part of this work? Your CRM will have a stable backend foundation ready for production growth. Thanks for sharing the details. I would be glad to help connect the pieces.

Hi, "A Contained, Mechanical Change" describes most of the data layer, but permission rules aren't mechanical — that's the part needing real design. Client-side rules only handled visible elements; server-side Policies must reject every direct API call a hidden button was quietly protecting. I'd build Gates/Policies per resource model, not one generic checker, so a bug in one can't expose others. File uploads switch to real multipart handling with type/size validation before storage, since base64 currently trusts the client fully. Every Eloquent query gets scoped to the authenticated account by default, not checked ad hoc per controller. Delivered as migrations, the API layer per your documented contract, dataLayer wired to real endpoints, scoped auth, server-enforced permissions, real uploads, and notes on any contract deviations. Thanks, looking forward to it.
