Description
platform for the bathroom installation industry. Our platform takes a bathroom installer seamlessly from
first customer contact through to invoicing and aftercare — survey, floor plan, 3D visualisation, quotation,
building regulations, scheduling, and payment — in one connected cloud platform. We are seeking an
experienced full-stack developer to build Version 1.0 of the Bathroom360 platform, ready for showcase at
London Build Expo, Olympia, November 2026. A full Product Blueprint is attached to this posting. Please
read it before submitting your proposal. Proposals that do not reference the Blueprint will not be
considered. --- THE PROJECT We require a complete SaaS platform built to the specification in the

bathroom installers, bathroom showrooms, and white-label partners. The platform includes 15 modules:
company onboarding, customer CRM, bathroom survey, floor plan designer, 3D visualiser, finishes and
tile specification, supplier product library, quotation engine, building regulations guidance, job scheduling,
installation workflow, snagging and sign-off, invoicing and payments, aftercare and warranty, and an AI
assistant powered by the Anthropic Claude API. --- TECHNOLOGY STACK REQUIRED The Blueprint
specifies the following technology stack. You must have demonstrable experience with all of the
following: - React and Next.js — frontend framework - Supabase — database, authentication, storage,
and edge functions - Three.js — 3D bathroom visualisation - Tailwind CSS — styling - Stripe —
subscription billing - Resend — email delivery - Anthropic Claude API — AI assistant integration - Vercel
— hosting and deployment --- WHAT WE ARE LOOKING FOR - A developer or small team with a
portfolio of completed SaaS projects - Demonstrable Three.js experience — please include examples of
3D work in your proposal - Experience building multi-tenant SaaS platforms with Supabase row-level
security - Strong communication in English — this is a collaborative project requiring regular updates -
UK-based or UK timezone working hours preferred --- PROJECT STRUCTURE This is a fixed-price
project with milestone payments. We do not pay hourly and we do not pay the full amount upfront.
Payment is structured as follows: - 25% on project start and infrastructure setup - 25% on completion of
Phase 1 modules (survey, floor plan, 3D, quotation, PDF) - 25% on completion of Phase 2 modules
(supplier library, invoicing, scheduling, AI) - 25% on final delivery, testing, and Expo readiness sign-off ---

Hi Steve,
A few questions before finalizing our proposal:
1. Has the HTML prototype already been fully documented?
2. Will fixture models and textures for the Three.js visualizer be supplied, or should we create the initial asset library?
3. Do you already have supplier product data available for import into the product library?
4. Will the AI assistant initially focus only on quote review, regulation guidance, and customer messaging as described in Version 1.0?
5. After London Build Expo, do you anticipate continuing with the same development team for Version 1.1 and Version 2.0?
Lastly, is your stated budget for £20,000 for Version 1.0?
Looking forward to your response.
Best,
VConn Pvt Ltd -
1. You mentioned having an existing architecture plan and backend scaffold. Which components are already implemented (PBX integration, AI conversation flow, dispatch engine, dashboard, database, authentication), and which are still planned? This will help determine where development effort should be focused.
2. How is engineer assignment expected to work? Will dispatch rely solely on skills, live availability, and geographic proximity, or should it also consider factors such as current workload, estimated travel time, SLAs, priority customers, and escalation rules?
3. What telephony platform is your HiHi system exposing for integration (SIP, API, webhooks, or 3CX-compatible interfaces), and are there any existing CRM, ticketing, or facilities management systems that the AI agent will need to synchronize with?
4. How much autonomy do you expect from the AI during a live call? Should it only capture structured information and create incidents, or should it also troubleshoot common faults, answer customer questions, schedule appointments, and make dispatch decisions without human intervention?
5. What would define a successful Version 1 deployment for you? Are your highest priorities production stability, AI conversation quality, dispatch accuracy, response times, scalability for multiple concurrent calls, or delivering a platform that can easily expand with additional automation and integrations?
