Role Description
We’re looking for a backend-heavy full-stack developer to partner with a design-first founder building custom software for service-industry clients.
The current projects are mostly B2B workflow apps:
-
Dashboards
-
Intake flows
-
Technician/admin portals
-
QR-code-based forms
-
Status tracking
-
Photo/documentation workflows
-
Client-specific tools
-
Lightweight integrations
The ideal person is a technical build partner who can:
-
Take a clear prototype and spec
-
Design the backend architecture
-
Build the Supabase infrastructure
-
Connect the frontend
-
Push back when something should be done differently
The first engagement will likely start with a smaller QR-code workflow app for service companies, with potential to grow into larger projects and a long-term collaboration.
Responsibilities
-
Design and build backend infrastructure using Supabase, PostgreSQL, Auth, RLS, Storage, Realtime, and Edge Functions.
-
Create clean database schemas with proper relationships, indexes, constraints, and migration planning.
-
Write secure Row Level Security policies for user-facing tables.
-
Set up authentication flows, permissions, sessions, and access logic where needed.
-
Build TypeScript/Deno Edge Functions for business logic, webhooks, scheduled jobs, and API integrations.
-
Integrate third-party tools such as Stripe, Twilio, OpenAI, SendGrid/Resend, Zapier/Make, or client-specific APIs.
-
Connect React/Tailwind frontends to the backend and help bridge the handoff between UI and infrastructure.
-
Review existing backend work and suggest improvements without overcomplicating the product.
-
Help turn prototypes into stable, scalable, production-ready applications.
Qualifications
-
3–6+ years of experience building production full-stack or backend-heavy web applications.
-
Deep hands-on experience with Supabase, including real shipped apps using RLS, Edge Functions, and Auth.
-
Strong PostgreSQL fundamentals: schema design, indexes, query optimization, constraints, and ability to read an EXPLAIN plan.
-
TypeScript / Node / Deno competence for building backend logic and Edge Functions.
-
Strong security instincts: RLS, input validation, permissions, and secrets management should be part of your default approach.
-
Clear written and spoken English for async handoff, documentation, and weekly Google Meet syncs.
-
Self-directed working style: able to take a spec doc and prototype, move independently, and surface questions in batches.
-
Strong communication skills, including the ability to explain tradeoffs and push back constructively when a better technical path exists.
-
A portfolio, case study, clickable prototype, or live/repo link that shows how you think and build.
Nice to have
-
Experience with third-party API integrations such as Stripe, Twilio, OpenAI, SendGrid/Resend, Make/Zapier, or client-specific tools.
-
Comfort with React + Tailwind so you can help wire frontends to the backend.
-
Experience with service-industry tools, such as CRMs, scheduling systems, operations dashboards, intake forms, or field-service workflows.
-
A point of view on workflow and process design, including state flows, approval chains, dashboards, or operational logic.
Benefits
-
Long-term, ongoing contractor relationship — not a one-off project.
-
Remote work, with LATAM timezone overlap preferred.
-
Flexible part-time setup: starting around a 10-hour weekly retainer, with potential to grow depending on fit and project flow.
-
High ownership and influence over technical direction.
-
Collaborative, low-bureaucracy environment.
