Zineddine
Benkhaled.

I design and ship full-stack production systems — from React/Next.js surfaces and microfrontends to Nest.js/Fastify APIs, PostgreSQL schemas, and event-driven backends. Frontend-leaning, with end-to-end ownership of architecture, data modeling, and delivery.

/ Full-stack case studies.
Project A / 01

Distributed Event Ticketing System

→ View Repo
NestJSRedisBullMQPostgreSQLMongoDBNext.jsStripe

Backend-heavy ticketing platform built for high-concurrency on-sales — atomic seat holds, queued checkout, and ACID order processing with a real-time buyer UI.

Backend
NestJS microservices (Auth · Catalog · Order) behind an API gateway. BullMQ checkout queue with Redis atomic holds and PostgreSQL row locks.
Data
PostgreSQL for orders and seat inventory. MongoDB for flexible event/seat-map documents. Redis for holds, pub/sub, and job backpressure.
Frontend
Next.js App Router with live seat map over WebSockets and Stripe test-mode checkout.
Project B / 02

Multi-Tenant SaaS Point-of-Sale

→ View Repo
FastifyPostgreSQL RLSDrizzleMicrofrontendsNext.jsTurborepo

Production-style B2B POS platform with database-enforced tenant isolation, an API gateway, and independently deployable microfrontends.

Backend
Fastify API gateway with JWT auth, Zod validation, and transaction-scoped tenant context via PostgreSQL RLS and Drizzle ORM.
Architecture
Next.js Multi-Zones host orchestrating Inventory and Checkout zones — each with isolated CI/CD in a Turborepo monorepo.
Frontend
Shared React UI package across zones. Host handles auth, dashboard shell, and cross-zone routing rewrites.
Project C / 03

Open-Source Data Grid Design System

→ View Repo
TypeScriptReactVue.jsZustandTurborepoOSS

Published OSS monorepo — headless grid engine with React and Vue adapters, handling 100k+ rows via virtual scroll and a shared design-token pipeline.

Core
Framework-agnostic @zineddinebk/grid-core engine — Zustand state, pure filter/sort/group pipeline, published to npm.
Frontend
React 19 and Vue 3 adapter packages with Tailwind preset, Storybook docs, and Playwright e2e coverage.
Tooling
pnpm + Turborepo monorepo. Changesets releases. GitHub Actions deploy demo and Storybook to GitHub Pages.
