Description

Experience Level: Expert
Full-Stack Developer for B2B Distressed Asset Marketplace (Next.js + Supabase + Stripe/Go Cardless)

Summary
Project Overview:

We are launching TurnaroundFlow, a specialized B2B marketplace and compliance platform connecting UK Insolvency Practitioners with institutional turnaround investors.

We already have the complete product specification, UI/UX architecture, database schema, and legal workflows prepared. We need a senior full-stack developer to build the MVP on a fixed-scope milestone basis.

Tech Stack:

Frontend: Next.js (App Router), Tailwind CSS, deployed on Vercel

Backend & DB: Supabase (PostgreSQL with Row-Level Security, Auth, and Storage)

Payments: Stripe / GoCardless Billing (recurring SaaS subscriptions: £99/mo and £349/mo)

Scraper/Worker: A lightweight Python script or cron job to ingest public corporate insolvency notices from The London Gazette API and Companies House stream.

Core Deliverables:

Role-based access control (Visitor, Professional Buyer, Institutional PE, and Insolvency Practitioner).

Filterable deal directory (by sector, SIC code, region, turnover).

Digital click-through NDA execution with timestamped database logging (for SIP 16 compliance).

Integrate CRM API: Trigger asynchronous background events to create/update Contacts and Companies in CRM upon user registration, digital NDA execution, and Stripe / GoCardless webhook subscription status changes

Secure Virtual Data Room (VDR) with role-gated PDF downloads.

Automated daily ingestion script from official public registers.

Requirements:

Proven portfolio with live Next.js + Supabase SaaS applications.

Strong understanding of PostgreSQL Row-Level Security (RLS) to ensure private files cannot be accessed without an active subscription.

Clear, communicative English and ability to work on milestones.

Please include links to live full-stack applications you have built using Next.js and Supabase. Generic agency copy-paste proposals will be ignored.

    -/ Should investors be able to access deal summaries before subscribing, with confidential details unlocked only after NDA acceptance?

    -/ Will Insolvency Practitioners publish and manage listings themselves, or will listings require admin approval?

    -/ Which CRM platform should receive registration, NDA, and subscription events?

    Hi Matthew

    Do you have end to end workflow and list of user types?

  • Meng L.

    Hello Matthew, Could we review the detailed technical documentation and have a concrete discussion regarding the implementation approach and milestones?

  • Anuradha G.

    Dear Client,

    Please help to clarify a few technical questions:

    #Which CRM platform are you using, and is its API documentation available?

    #Do you have the London Gazette and Companies House API access/configuration ready?

    #Should both Stripe and GoCardless be implemented in the MVP, or is one the primary payment provider?

    #Is the VDR expected to support document previews, download tracking, and access audit logs?

    #Are the UI/UX designs and database schema available in Figma and SQL format?

    Warn Regards,
    Anuradha

    A few quick questions:

    1. Should every data room PDF be watermarked with the buyer's name and the download time, so a leaked document can be traced back to the person who downloaded it? It changes how the downloads are built, so I want to know before Milestone 3.

    2. Is the NDA signed once on the platform or once per deal, and who is the other party: the platform, the Insolvency Practitioner or the company in insolvency? That decides what the log must store for your SIP 16 workflow.

    3. If a payment fails or a subscription ends while a buyer is inside a live deal, should access stop at once, after a grace period, or when that deal closes?

  • Tosin O.

    Have you already decided what level of document access investors should get under each subscription plan, or is that something you will like to finalise during development?

  • Sajawal I.

    With the full specification, UI/UX architecture, database schema and legal workflows already prepared, TurnaroundFlow looks ready to build rather than design from scratch. Could you confirm how you would like the work split into milestones and which part you expect first?

  • Asif Q.

    Hi Matthew,

    Quick question on the data room access rules. Should a buyer need both an active subscription and a signed NDA for that specific deal before its PDFs unlock? Or does one NDA cover every deal on the platform? Knowing this early decides how the security rules and the SIP 16 audit log are set up.

    Thanks,
    Asif
