Hello.

I have real experience in developing modular SaaS on Next.js (App Router + Server Actions), with integration of Supabase Auth + RLS, Stripe Subscriptions + Webhooks, OpenAI API, and typed architecture by feature modules.

I am ready to build a technical MVP exactly to the specified scope, without unnecessary features:

Supabase Auth (registration / login / reset) + RLS policies

Dashboard: active plan + usage
…
Workspace

AI Chat (brief history, Server Actions, dedicated LLM layer)

MiniGPT module (separate table, access by plan)

Stripe Billing: 3 plans, webhook events (activation / cancellation / update) with synchronization in Supabase

Admin panel (list of users + usage)

Feature-based architecture + brief README for modules

Tailwind + shadcn, minimalist UI

I understand the requirements: KISS, modularity, extensibility, without Nest.js/GraphQL/microservices and unnecessary abstractions. Communication is asynchronous, NDA — no problem.

I am ready to provide technical evidence (fragments of Server Actions + Supabase RLS / Stripe Webhooks).

Здравствуйте! Имею опыт разработки модульных SaaS на Next.js 14/15 (App Router + Server Actions), Supabase RLS, Stripe Subscriptions + Webhooks и интеграции OpenAI API. Готов реализовать ваше MVP строго по ТЗ, в стиле KISS & Modular, с выделенным LLM-слоем, feature-based структурой и минималистичным UI.

Прикладываю технические доказательства:

Код Server Actions + Supabase RLS:
"use server";
import { createClient } from "@/lib/supabase/server";
export async function createWorkspace(d) {
const s = createClient();
… const { error } = await s.from("workspaces").insert({ name: d.name });
if (error) throw new Error(error.message);
}
