JCD Digital builds and operates custom software for businesses. You'd start on a live production CRM/operations app — React/TypeScript front end, Supabase back end, real users on it every day.
I build fast with an AI-assisted, low-code-adjacent workflow and ship in tight sprints. What I need is someone who understands what's happening UNDERNEATH that layer: reads the Supabase logs, finds the real root cause, and keeps a live app from breaking.
This is not a "no-code / AI does it for you" gig. I already handle the AI-assisted layer — I need the engineering judgment beneath it.
WHAT YOU'D DO
- Debug and fix issues across a live React/TypeScript + Supabase app
- Write and review PostgreSQL: schema, migrations, and Row Level Security (RLS) policies
- Build and troubleshoot Supabase Edge Functions
- Turn plain-language requirements into clean, scoped, testable changes
- Work ADDITIVELY — never touch existing policies or schema without explicit scope
- Test rigorously before calling anything done
MUST-HAVES
- Solid React + TypeScript
- REAL Supabase experience — RLS, edge functions, auth, storage (not "I skimmed the docs")
- PostgreSQL you can reason about by hand — you can write an RLS policy and explain why it works
- Comfortable in a fast, AI-assisted build environment (Lovable, v0, Bolt, Cursor — or eager to learn)
- You explain root cause in plain language, not just paste a fix
- Discipline around live production — you understand WHY you re-test after every deploy
NICE TO HAVE
- Third-party API / webhook integration (CRM, telephony, accounting)
- Experience on apps without a staging environment
- Any client-facing or consulting background
HOW I WORK
- One sprint = one focused, testable deliverable
- Diagnose root cause BEFORE writing the fix
- Additive, not destructive — existing functionality is sacred
- Fast pace, direct communication, no fluff
LOGISTICS
- ~5–15 hours/week to start, with room to grow for the right person
- Overlap with US Central time required for real-time collaboration
- NDA + IP agreement before any system access — non-negotiable
TO APPLY — read carefully (most won't)
1. Start your proposal with the word TEAL so I know you read the whole post.
2. In 2–3 sentences: I deploy straight to live production with no staging environment. What's the one thing you'd always verify before AND after a deploy, and why?
3. Link ONE Supabase/PostgreSQL project where YOU personally wrote RLS policies or edge functions — and in one line, how you handle access to a client's sensitive data.
Generic AI-written proposals and "I can do everything, hire me" pitches get archived unread. I shortlist a few people for a small paid test task before any ongoing work begins.
