postgresql, react-js, typescript, api-integration

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.
