Full-Stack Developer — Next.js / Supabase Web App & Client Portal Build (Fixed-Price)

We build lean, production-ready web apps — internal tools, client portals, and quote/RFQ trackers — for our clients, and we're re-engaging the senior developers our team has already spoken with. If we've talked before, you're already set on the NDA and our standard structure, so consider this the first live project rather than a cold start. How we work: fixed-price per project, paid at roughly 30% of the client's project value (this first build is ~$1,500). Senior devs own the build end to end; the end client owns 100% of the code and it's deployed to their own accounts. An NDA is required before we share the full brief and the client's identity. First project: a lightweight internal web app that becomes a company's single system of record for incoming quote requests. Core pieces: - A public "Request a Quote" form (captcha + rate-limiting) that creates an Opportunity record - An Opportunity data model: organization, multiple product lines (many-to-many), stage, estimated value, commission % - A ~50-record directory of reference data, lightly editable - A simple manual routing/handoff dropdown + a single-recipient new-request email - Internal staff authentication - Clean handoff: repo, env docs, and a short deploy runbook Trimmed MVP — roughly 6-7 dev-days, target 1.5-2 weeks. Stack is your call, but we lean Next.js / React / Node / Supabase or Postgres. Do well here and there's a steady pipeline of similar fixed-price projects. Please include in your reply: 1. Confirm you're still good with the fixed-price / ~30% structure and signing an NDA 2. Your earliest start date and a realistic timeline for the MVP above 3. Your preferred stack, and confirmation the client gets full code ownership + handoff docs 4. Two or three live links to internal tools / SaaS apps you've built end to end (with auth + real CRUD) Looking forward to working with you.
