We are building our own proprietary Business OS — a suite of interconnected web applications powered by Next.js, Supabase, and Claude AI — to replace spreadsheets and fragmented tools. Tech Stack You must be comfortable with the following — no learning on the job: • Next.js 14+ (App Router) + TypeScript • Supabase — Postgres, RLS, Auth, Edge Functions (Deno/TypeScript), Storage, Realtime • Anthropic Claude API — tool use, streaming, multi-turn agents • Vercel deployments + GitHub CI/CD • Tailwind CSS + shadcn/ui • REST APIs: Shopify Admin, Amazon SP-API, MercadoLibre, Google Search Console, DataForSEO Ideal Profile • 3+ years building production SaaS or internal tools with Next.js + Supabase (or equivalent Postgres-backed stack) • Experience building or integrating AI agents (Claude, OpenAI, or similar) — not just wrappers, real tool-use flows • Strong SQL skills — you can write complex queries, design schemas, and set up RLS policies without hand-holding • Self-directed: you can take a module spec, ask the right clarifying questions, and ship without daily check-ins • Comfortable working async with a hands-on technical CEO • Bonus: experience with Mexican e-commerce platforms (MercadoLibre, Shopify MX), shipping APIs (Skydropx, Estafeta), or CFDI/SAT integrations Not a Fit If... • You need detailed tickets for every task — we move fast with high-level specs • You haven't shipped a real product with Supabase and Next.js • You treat AI APIs as a black box — you need to understand context windows, tool use, and prompt design • You're unavailable for a weekly sync call (30 min, video) How We Work We use a modular sprint approach. You pick up a module, we align on spec in a short call or async doc, you build and deploy, we review together. No Jira, no bureaucracy. GitHub + Vercel + a shared Notion doc is our workflow. This is a long-term engagement. If the first module goes well, there's 12+ months of work ahead across all the modules listed above. How to Apply In your proposal, please include: 1. A link to a Next.js + Supabase project you built and can walk us through. 2. One example where you integrated an AI API (Claude, OpenAI, etc.) into a real product — describe what tools/functions you used.
