A full stack partner for businesses that value quality.

Master's degree in Computer Science. 6+ years across shipping, ride-hailing, real estate, WMS, digital media, and education. End-to-end product expertise — from analysis and design to delivery and performance.

I build production-grade digital products with React, Next.js, Node.js, and MongoDB, with TypeScript across the stack.

Mobile apps live-and-breathe in React Native and Expo — cross-platform experiences that feel native and perform well.

I'm recognized for being curious, proactive, and solution-oriented — adapting quickly and delivering value in demanding, dynamic environments.

FIXOE

Uber-for-artisans — home services on demand across Europe, minutes after you need them

Full Stack Engineer · Architecture & Delivery

FIXOE turns a broken pipe, a dead outlet or an urgent repair into a five-minute decision. European households open the app, describe the problem, and get matched in real time with a verified plumber, electrician or handyman already nearby. I designed and delivered the full ecosystem — the client app, the artisan app, the operations dashboard and the live dispatching engine — so the business can scale city by city without losing control of quality, pricing or response time.

Key contributions

  • Designed the end-to-end architecture across mobile, admin, and API layers.
  • Real-time artisan dispatching and live location updates with Socket.IO.
  • Role-based flows for clients, artisans, and operations teams.
  • Localized for European markets with multi-country, multi-currency support.
  • Data modeling for scale, search, and reliable state transitions.

Quick Silver · WMS Mobile

A handheld warehouse — every SKU, scan and shipment under control in real time

Mobile Developer · WMS & Logistics · KSA

Quick Silver operates transport and storage for clients who can't tolerate stockouts or lost pallets. I replaced paper tickets and aging scanners with a rugged mobile WMS that warehouse teams carry in their hand all day. Receiving, put-away, picking, packing and shipping all happen through one flow — even when the warehouse Wi-Fi drops — and sync back to the central system the moment a signal returns. The business gains inventory accuracy, faster order cycles and full operational visibility from the floor up.

Key contributions

  • Developed the Quick Silver WMS mobile app end-to-end for warehouse operators.
  • Implemented barcode/QR scanning flows for receiving, picking, and packing.
  • Designed offline-resilient state with reliable sync to the central WMS.
  • Built role-based workflows for warehouse staff, supervisors, and dispatch.
  • Optimized for speed and durability in warehouse environments.

Hirinii

Record a 1:30 video story, build your digital CV and let recruiters discover who you really are

Full Stack Engineer · Product & Architecture

Hirinii puts a face and a voice on every CV. Candidates record a 1:30-minute video story where they introduce themselves in their own words — their background, their strengths, what they're looking for — giving recruiters a real sense of who they are before a single interview. Beyond the story, candidates build a full digital profile (personal info, experience, education, skills, languages) and get a personal portfolio they can share via link, QR code or a physical card they can order from the platform. When a recruiter scans the QR on the card, they land straight on the candidate's portfolio and story. On their dashboard, candidates track everything in real time: who viewed the CV, how many downloads, and how many people watched the story. The platform also offers courses for career development and a contact support channel. On the admin side, ID and diploma verification is handled manually by the operations team through a dedicated dashboard.

Key contributions

  • Built the 1:30 video story feature — candidates record a brief self-introduction that recruiters watch before any interview.
  • Developed the candidate web app: profile builder, personal portfolio page and real-time analytics dashboard.
  • Implemented CV sharing via unique link, dynamic QR code and physical card ordering.
  • Integrated analytics: CV views, downloads, story views and recruiter tracking.
  • Developed the admin dashboard for manual ID and diploma verification by the operations team.
  • Built the courses page for career development and the contact support flow.

Yassir · Mobility B2C

The web front door for a super-app moving millions of riders across Africa

Full Stack Developer · Mobility & Ride-hailing

Yassir is one of Africa's largest super-apps, and the B2C web platform is the public entry point into its ride-hailing service. Every improvement touches millions of riders — from students commuting in Algiers to families booking a Comfort ride, to women opting for the Yassir Women service. I work on the booking, tracking and post-trip experience with a single goal: make every journey faster to start, easier to follow, and more trustworthy to come back to.

Key contributions

  • Developed the mobility-b2c-web application for Yassir's VTC service.
  • Shipped performance and UX improvements across high-traffic booking flows.
  • Collaborated cross-functionally on product, design, and backend integration.

Rohool Courier

The driver side of a Saudi last-mile operation — every pickup, route and drop-off in one app

Mobile Developer · Delivery & Logistics · KSA

Rohool moves parcels across Saudi Arabia, and its courier app is the single tool every driver lives in from the first shift to the last delivery. Built Arabic-first with full RTL care, it guides drivers through pickups, live navigation, proof of delivery and incident handling — even in zones with unstable connectivity. The result: faster rounds, fewer failed deliveries, and operations managers who finally see a live, accurate picture of the fleet.

Key contributions

  • Developed and shipped the Rohool Courier mobile application end-to-end.
  • Implemented Arabic-first RTL interface with full localization.
  • Built live tracking, route visualization, and delivery status flows.
  • Integrated secure authentication, driver onboarding, and order management.
  • Optimized performance for reliable use across varied network conditions.

AB Promotion

A luxury real estate brand, digitized end-to-end — from first app download to signed lead

Full Stack Engineer · Architecture · DevOps

AB Promotion Immobilière builds haut-standing residences across Alger, Boumerdès and Tipaza and sponsors Batimatec 2026. I gave the brand a digital ecosystem that matches the quality of its buildings: a mobile app where premium clients explore residences, book visits and track their interest; an admin back-office where the sales team manages leads, appointments and releases; and a backend and deployment pipeline reliable enough to run the business on. Every new residence is now live for sales teams and clients the same day it's announced.

Key contributions

  • Architected and built the full three-tier stack: backend API, admin dashboard, and mobile app.
  • Developed the Node.js / Express REST API with MongoDB — residences, leads, appointments, virtual tours.
  • Built the Next.js admin dashboard for content, leads, appointments, and residence management.
  • Delivered the My AB React Native mobile app with bilingual FR / AR (RTL) support.
  • Set up a CI/CD pipeline for automated builds and zero-downtime deployments.
  • Deployed the API and admin dashboard to Hostinger with custom domain, SSL, and monitoring.
  • Shipped the iOS app to the App Store; Android submission pending Google Play approval.

Bessa Promotion

20 years of Algerian real estate, turned into a digital sales engine

Full Stack / Mobile Developer · Real estate

Bessa Promotion is one of Algeria's most established real estate developers, with two decades of residences behind the brand. I led the digital transformation that made that catalog sell online: a modern bilingual FR/AR website that ranks and converts, a headless CMS so marketing can launch a new residence without a developer, landing pages purpose-built for each project (Avena, La Pinède, Les Massyles, Midelt, Fusion), and the Buy Bessa mobile app that lets future owners reserve a unit from their phone. The outcome is simple: fewer brochures, more qualified leads, and a sales team that moves at the speed of demand.

Key contributions

  • Migrated the corporate website from React.js to Next.js for better SEO and performance.
  • Integrated Strapi v4 as headless CMS for managing residences, articles, and localities.
  • Built bilingual French & Arabic localization with full i18n support.
  • Delivered marketing landing pages for residences (Avena, La Pinède, Les Massyles, Midelt, Fusion).
  • Added a reservation flow in the Buy Bessa mobile app for future customers.
  • Contributed to Meskane — a platform for buying, selling, and exploring real estate.

Ola Spa & Gym

The daily companion of a premium wellness brand — members, schedules and subscriptions in one place

Mobile Developer · Wellness & Fitness

Ola Spa & Gym is a premium wellness chain operating across three centers in Algeria. I built the member-facing mobile app that now replaces phone calls and reception queues: members browse classes and spa treatments, check live availability, book their slot and manage their subscription directly from their phone. For the business, it means fewer no-shows, higher retention and a single source of truth for planning. Live on the App Store and Google Play, with a v1.1 already shipped after real-world feedback.

Key contributions

  • Developed the Ola Spa & Gym mobile app end-to-end for iOS and Android.
  • Built booking flows across GYM, PISCINE, SPA and NUTRITION with capacity management.
  • Implemented real-time class schedules with instant availability updates.
  • Designed subscription selection — from 1x/sem packs to Illimité and coaching personnel.
  • Integrated nutrition journey: consultations, suivi nutritionnel, and InBody 770 reports.
  • Shipped v1.0 (Aug 2024), then delivered v1.1 feature update with planning improvements.
