Backend Developer for B2B AI Platform MVP (Lovable)
Budget: £250 – £750 GBP
**Frontend/Backend Developer Needed to Finalize MVP of AI-Enabled B2B Platform (Built in Lovable)**
---
#Project Overview:
We’re in the final stages of building a **private B2B platform** designed to streamline access between two verified user groups. The platform leverages **contribution-based access**, AI-enhanced decision support, and usage-based behaviour scoring.
The frontend is **built and styled inside Lovable**, with advanced flows, tiered membership logic, and a modern design aesthetic already in place. We now require a **skilled developer** to finalize key backend connections, implement identity validation, and prepare the system for **beta launch**.
---
#What’s Already Done:
* Frontend UI/UX complete in **Lovable**
* Custom user onboarding for two verified roles
* Contribution gate system (access granted based on submitted contacts)
* Call scheduling + credit logic
* AI-enhanced assistant tools
* Tiered packages with usage limitations
* Feedback workflows + scoring logic
* Early analytics dashboard built out
---
#Your Responsibilities:
You’ll be supporting the final 20% of build tasks needed for closed beta:
##Backend Logic & Database Setup
* Implement logic to limit user access based on activity quotas
* Track behavioral scoring and enforce time-based restrictions (e.g., suspensions, usage limits)
* Enforce relationship caps and repeat-use restrictions
* Finalize data models for evaluation scoring
##Third-Party Integrations
* **Identity validation integration** (e.g., LinkedIn OAuth or equivalent)
* Payment system setup (e.g., Stripe) for gated features and team packages
* Optional: Bot protection and abuse prevention logic
##Access Management
* Ensure locked states are enforced until key triggers are met
* Support user role relationships and approval-based unlocking of functionality
* Ensure filters and visibility logic match user status and account type
##Code Cleanup & QA
* Refactor bloated onboarding file into components
* Resolve minor UI bugs (e.g., icon tooltips, conditional props)
* Perform testing across key user paths (onboarding, gated access, scheduling, evaluations)
---
#Tools In Use:
* **Lovable** (no-code builder with custom JS/TS support)
* **Supabase** (preferred backend/db)
* **OpenAI API** (already integrated in parts of the logic)
* **Lucide + shadcn/ui** (frontend components)
* **Stripe** (to be configured)
* **LinkedIn or equivalent OAuth** (to be integrated)
---
#Ideal Profile:
* Full stack (or strong frontend + light backend) experience
* Familiar with no-code tools, ideally **Lovable**
* Comfortable working in low-code environments + extending with custom logic
* Strong understanding of rate-limited APIs (LinkedIn, Stripe, etc.)
* Bonus: Experience in B2B SaaS or AI tool integration
---
#Timeline:
* Work begins ASAP
* Final beta version expected in **2–3 weeks**
---
#Budget: $300

#To Apply:
Please send:
1. A short note on how you'd approach user identity verification + quota gating
2. Links to any similar dashboards or role-based platforms you’ve built
