DJOUDI MANSOURI

AI DRIVEN FULLSTACK SOFTWARE ENGINEER

LF-7 « D-MANSOURI »

One pilot, full stack.

I'm Djoudi, five-plus years flying the whole machine, from the interfaces people touch to the services underneath and the cloud that keeps it all in orbit. Currently consulting for Cegid as the sole fullstack & AI developer on its Retail Cloud tools; before that, technical lead of crews up to eight. Each system of this ship is one of mine. Scroll to inspect.

Systems

SYSTEM 01 - COCKPIT

Interfaces & UX

The seat where human meets machine. Five years building the screens people actually use, on web and mobile, from the design system down to the last pixel. Interfaces that feel obvious, load fast and move with intent rather than decoration.

  • React
  • Next.js
  • TypeScript
  • React Native

SYSTEM 02 - SENSOR ARRAY

Back-end & Data

Nothing flies blind. Services shaped around how the business really works, APIs that hold under load and data tuned for speed, with live streams feeding the instruments so every decision runs on today's numbers, not yesterday's.

  • Java · Spring Boot
  • Node.js
  • PostgreSQL
  • Kafka

SYSTEM 03 - WING ASSEMBLY

Creative Development

The part that makes it fly instead of fall. Motion, particles and camera choreography that turn a product into an experience, like every effect on this very site, plus dashboards that let the data tell its own story.

  • Three.js
  • R3F
  • GSAP
  • D3.js

SYSTEM 04 - SHIELD GENERATOR

Security & Testing

What keeps the hull intact. Security audits and hardening on live production apps, and a test-first discipline with coverage above 80%, written in the language of the business, so failures die in staging, never in flight.

  • OWASP ZAP
  • Pentest
  • TDD · BDD
  • Cypress

SYSTEM 05 - MAIN ENGINES

Cloud & DevOps

Thrust at enterprise scale. Cloud platforms built to grow with the business, automated delivery from commit to production, and monitoring tied to service-level objectives, so every launch is repeatable, observable and provable.

  • Azure
  • Kubernetes
  • Docker
  • CI/CD

Missions

MISSION 01 - PERSONAL CRAFT

This Portfolio

An interactive flight through my work, with hand-built particle typography, procedural planets and a scroll-driven camera. No template, no game engine, every effect written from scratch. The side projects orbit as moons; click one.

  • React Three Fiber
  • GLSL
  • Drei

Satellites

SATELLITE 01 - OPEN SOURCE

Magical Typewriter

An open-source library of stylised typewriter effects that any developer can drop into their app. Published, documented, used by strangers: the best kind of code review.

  • React
  • TypeScript
  • GSAP
  • npm

SATELLITE 02 - EXPERIMENT

Rank the Market

Live, multiplayer tier lists for stocks, ETFs, crypto and memecoins. Share a link and the whole room drags assets into tiers together, cursors and all, while every public board feeds a community ranking recomputed each minute. No accounts, no advice, just opinions.

  • Next.js
  • React Three Fiber
  • Drei

SATELLITE 03 - GAME JAM

Void Invaders

A browser shoot-'em-up built in three days for the Opera GX Game Jam. Tiny scope, shipped on deadline, proof that constraints are fuel.

  • GameMaker Studio 2
  • GMSL

SATELLITE 04 - FULLSTACK, HRIS SAAS

RH-Partner

A microservices HRIS used by large accounts and SMEs. I built and maintained its key modules (time tracking, payroll, time management), from the Spring Boot REST APIs to the Angular screens, and advised clients through version upgrades.

  • 13 LEADS CONVERTED
  • Java · Spring Boot
  • Angular
  • PostgreSQL
  • JUnit · Mockito

SATELLITE 05 - TECH LEAD, PET CARE

Mister Coocky

A pet wellness and e-commerce platform: web apps for businesses, mobile apps for pet owners. As technical lead I trained and steered a team of four to six developers, designed the React and React Native apps on a Spring Boot and PostgreSQL back-end, and shipped them to the web, Android and iOS.

  • 15,000+ USERS
  • 30+ B2B PARTNERS
  • React
  • React Native
  • Java · Spring Boot
  • PostgreSQL
  • AWS

MISSION 02 - LEAD DEV, EDTECH

DinoBot

An AI tutoring platform I led from first prototype to production with a crew of five. Generative AI turned into a patient one-on-one tutor, shipped behind a strict test-first pipeline so nothing reaches a learner unproven.

  • 5,000+ LEARNERS
  • 95% SATISFACTION
  • 85%+ TEST COVERAGE
  • Next.js 14
  • OpenAI SDK
  • Prisma
  • PostgreSQL
  • Cypress

Energy-optimisation dashboards for industrial sites, on a back-end modelled around the business itself. Led a team of eight and shipped to factory floors.

  • −28% CLIENT ENERGY USE
  • React
  • D3.js
  • Java · Spring Boot

SATELLITE 02 - LEAD FRONTEND

On Air & One Fitness

Two fitness brands' legacy apps modernised and their whole subscription journey rebuilt, payments included, pixel-perfect to the designs.

  • +43% SUBSCRIPTIONS
  • React
  • Vite
  • Tailwind
  • Cypress

MISSION 03 - CEGID RETAIL CLOUD

Live Cloud Dashboard

The observability platform for Cegid's Retail Cloud: live service-level dashboards across the whole infrastructure, secure access scoped to every client and team, and custom charts built for digging into incidents. Designed and built end-to-end on a consulting mission, as the team's sole fullstack & AI developer.

  • MOST ACCLAIMED TOOL, RETAIL CONNECTION ’26
  • IN PROD FOR LVMH · L’ORÉAL · D&G
  • Next.js
  • TypeScript
  • Fastify
  • Azure

SATELLITE 01 - BENCHMARKING

CockroachDB Stress-Test

A benchmarking and load-testing rig for a distributed SQL database: latency, throughput and behaviour under sustained load, measured rather than assumed.

  • CockroachDB
  • Kubernetes
  • Grafana

SATELLITE 02 - NETWORK

Cloud Speedtest

Measures real latency from any client down to each of the Cegid Cloud's regional PODs, a live weather report for the whole fleet.

  • Node.js
  • Azure

SATELLITE 03 - INGESTION

CDN Logs Forwarder

Streams CDN access logs into the monitoring platform, with durable buffering so not a line is lost when something downstream fails.

  • Node.js
  • Akamai
  • Azure

SATELLITE 04 - TOOLING

Dynamic Release Schedule

A calendar-and-timeline engine built from scratch to replace a static release schedule. Every region, every timezone, every release mapped to its planning cycle, from test through to production.

  • React
  • TypeScript
  • Fastify

SATELLITE 05 - NETWORK SECURITY

A self-service portal where Cegid's clients manage their own API keys and network access settings.
