React + Supabase Developer — Workplace Verification of Competency Web App Fixed price · AEST timezone preferred · Full spec and working prototype provided Note: the budget shown is a placeholder. I expect bids in the $800–$1,200 USD range for a complete, quality build. Bids significantly below this will not be considered. What this project is I need a developer to wire up a fully-designed React prototype into a production web application. The UI is complete — you are not designing anything. Your job is to connect it to a real database (Supabase), add authentication, and set up automated email delivery. The application is called SpecialisedVOC. It is a workplace verification of competency platform used to record and certify that workers can safely operate specific pieces of machinery. It handles approximately 3,000 assessments per year across multiple assessors and sites. The prototype (React .jsx file) and a full developer specification document are ready to send to shortlisted applicants. You will not be guessing at requirements — everything is documented. What needs to be built The prototype runs entirely in-memory. You need to replace the simulated state with real services: • Supabase database — schema provided, 7 tables, row-level security policies specified • Supabase Auth — assessor and admin login (email + password). Candidate path requires no login. • Real-time data — replace in-memory React state with live Supabase queries across all three user flows • PDF certificate generation — react-pdf, rendered from the existing certificate layout in the prototype • Email delivery via Resend — two triggers: knowledge check submission confirmation, and VOC certificate on assessment completion • Admin CRUD panel — manage machinery types, tasks, question banks, and practical checklists • Staging environment — separate Supabase project at a staging subdomain, required before production go-live • Production deployment — Netlify or Vercel, connected to GitHub for auto-deploy Three user interfaces (all in one app) Candidate Phone / browser. No login. Enrols, nominates machinery, completes a 10-question knowledge check, receives a reference number. Flow is 4 steps. Assessor iPad / browser. Authenticated. Searches candidates by name or reference number, reviews knowledge check responses, conducts practical assessment via checklist, issues VOC certificate. Admin Desktop / browser. Authenticated. Full register, statistics dashboard, manages assessors and question banks. Tech stack Frontend React (Vite) — prototype is a single .jsx file Database / auth Supabase (PostgreSQL + Supabase Auth) Email Resend PDF react-pdf Hosting Netlify or Vercel Repository GitHub — you set it up and hand over access Do not propose an alternative stack. The stack is fixed. If you are not experienced with React and Supabase specifically, please do not apply. Estimated effort Based on the documented scope, I estimate 41–58 hours of development work. The UI is complete — no design time is required. Quote based on your assessment of the spec, not this estimate. Payment will be split into two milestones: • Milestone 1 (50%) — staging environment live, all features working, product owner sign-off • Milestone 2 (50%) — production deployed, domain configured, repository and Supabase access handed over What I will send shortlisted applicants • The working React prototype (.jsx file) — open in any browser, fully interactive • Developer specification document (Word) — system overview, complete database schema with SQL, RLS policies, stack decisions, prototype guide, scope, delivery requirements, and clarifying questions You will have everything you need to quote accurately before committing to the project. What I need from you In your application, please include: • Your fixed price quote (AUD ONLY) • Confirmation that you have experience with React and Supabase — ideally a link to a project or past work that used both • Your timezone and typical working hours • Estimated turnaround from project start to staging sign-off Applications without a quote and without evidence of React + Supabase experience will not be considered. Generic applications will be declined. About the project Product specialisedvoc — Workplace Verification of Competency Operating under Halo (Queensland, Australia) Volume ~3,000 assessments per year Timeline Beta testing to begin as soon as build is complete Ongoing work Likely — beta will generate change requests. Suitable candidate may be retained for ongoing support. Timezone AEST (UTC+10/+11). Developer must be available for real-time communication during business hours AEST. Questions before applying are welcome.

Hello, I’ve read the specification carefully and this is exactly the type of React + Supabase integration project I work on. Since the UI prototype is already complete, the focus will be replacing in-memory state with secure, production-ready services and ensuring the three user flows run reliably. My approach • Implement the Supabase schema (7 tables) with RLS policies exactly as defined • Integrate Supabase Auth for assessor/admin login while keeping the candidate flow public • Replace React state with live Supabase queries and mutations across candidate, assessor, and admin flows • Generate certificates using react-pdf based on the provided layout • Configure Resend email triggers for knowledge-check confirmation and VOC certificate delivery • Build the Admin CRUD panel for machinery types, question banks, tasks, and checklists • Set up staging environment (separate Supabase project) before production • Deploy to Vercel or Netlify with GitHub auto-deploy Timezone: Available during overlapping AEST hours I have experience building React + Supabase applications with authentication, RLS policies, and real-time data flows, and I’m comfortable working within a fixed stack and documented specification. Let’s open the chat. I’d be happy to review the prototype and specification so I can confirm the exact implementation plan before starting. Best, Jenifer

Hi, This is a very clear build, and since the UI and spec are already complete the focus should stay fully on clean integration, stability, and predictable delivery. We have strong experience working with React and Supabase together, including auth flows, real-time queries, and structured CRUD systems. For this project, we would focus on wiring the prototype cleanly to Supabase, implementing RLS correctly across all flows, and making sure PDF generation and email triggers run reliably under real usage. we are comfortable working within a fixed stack and structured spec like this, and I understand the importance of staging validation before production rollout. I can align with AEST working hours for communication during key build stages. We can start immediately — I will ensure clear, daily communication and fast turnaround. You’ll always know the exact progress.

I can build your SpecialisedVOC app exactly as outlined, connecting the React prototype to Supabase for all data, auth, and RLS policies. I’ve delivered similar projects where I replaced in-memory states with live Supabase queries, handling multiple user roles and real-time updates. From your spec, a key to smooth staging and production goes will be securing the admin CRUD with proper Supabase RLS and ensuring email triggers via Resend fit cleanly into your workflows. Should I implement Supabase edge functions for email triggers, or handle those via client calls from the app? Also, do you want PDF generation server-side or entirely in-browser via react-pdf? I estimate completing the staging build within 10 business days of starting, working during AEST hours for real-time collaboration. I quote AUD 1,100 for the full build, covering all features as described, deployment setup, and handing over repo + access. Ready to start as soon as you share the prototype and spec. I can jump on a call to clarify any details and kick off the project.

The chief peril in transforming an in-memory React prototype into a live Supabase-backed platform lies in preserving data integrity amid real-time state synchronization and complex row-level security policies; your project demands seamless live queries, strict access controls, and reliable event-triggered processes to support thousands of annual assessments without compromise. Integrating React (Vite), Supabase Auth with specific user roles, react-pdf generation, and Resend email workflows underscores the necessity for precision and depth in your specific stack. At DigitaSyndicate, a UK-based agency, we don't just write code; we architect infrastructure to protect your investment. Local UK accountability ensures rigorous adherence to best practices and security standards, giving you direct oversight and peace of mind in every stage from staging to production deployment. Have you thoroughly validated Supabase’s row-level security to prevent any elevation of privilege when multiple assessor and admin roles interact concurrently through your unified React interface?
