The challenge

Flexy reseller networks in Algeria were juggling separate operator portals, WhatsApp receipt chaos for CCP funding, and no shared wallet or commission model across wholesaler → retailer hierarchies for Mobilis, Djezzy, and Ooredoo.

The solution

A hierarchical wallet platform that centralizes operations: prepaid DZD balance, dual funding (instant CIB + CCP receipt approval), Flexy Gros & Detail across the three mobile networks, Idoom/cards/games catalog, commission tracking with transform-to-balance, and role-based access for admin, wholesaler, and retailer — on web and Android.

What I built

• Multi-role auth with session login, OTP SMS validation, security PIN, remember-me, and account lockouts
• 3-tier reseller hierarchy (admin / wholesaler / retailer) with scoped data access
• Prepaid DZD wallet with balance, gains, and debt settlement
• Flexy operations for Mobilis, Djezzy, Ooredoo (Gros & Detail) via OneClickDz API + optional Mobilis GSM USB modem
• Idoom ADSL/4G packs, operator recharge cards, and game gift cards (PUBG UC, Free Fire)
• Dual funding rails: OcPay CIB/E-DAHABIA checkout + CCP receipt upload to S3-compatible storage with approve/reject workflow
• Commission system with per-operator gain percentages and gains → spendable balance transformation
• Balance transfers down the hierarchy, reclaim, and debt settlement
• Real-time SSE updates and Firebase push notifications for Android
• Dashboard analytics with ApexCharts, PDF/QR invoice verification
• Trilingual UI (FR / EN / AR with RTL), Docker Compose, CI/CD to production VPS
• Self-hosted Android APK distribution and companion WebView experience
• Automated low-balance email alerts and scheduled database backups (email + Google Drive)

Impact

Unified daily Flexy operations (fund → sell → commission → transfer) in a single secure platform for Algeria’s three mobile networks plus Idoom and game cards — with full wallet visibility, per-level performance, and automated alerts/backups to cut portal switching and reduce funding friction and data-loss risk.

The challenge

A cooperative needed one system to replace scattered spreadsheets and manual tracking for products, stock, clients, suppliers, orders, and payments.

The solution

A custom ERP that centralizes operations: FIFO inventory with expiration tracking, order and billing workflows, client/supplier payment management with installment plans, expense tracking, and accounting reports with charts — all behind role-based access for different staff roles.

What I built

• Product catalog with categories and image management
• FIFO stock system with batch history and automated low-stock alerts
• Order management with status tracking and PDF delivery notes
• Invoicing (factures & proformas) with PDF generation
• Client and supplier payment modules
• Accounting dashboard and sales reports
• Product & client analytics with CSV/Excel export
• User management with 5 permission levels
• Automated email notifications and scheduled database backups
• Installment payments (paiement par facilité) on client orders, with full payment traceability and automatic notification when a payment is completed
• Accounting charts & graphs — revenue breakdown (HT/TVA/TTC) and sales progression over time, filterable by date range
• Admin expense manager with itemized expense lines, so the admin can track exactly where the money goes
• Commercial activity traceability — per-salesperson view of orders created, amounts sold, and credit paid/remaining, with date filters
• Invoice management with date/status filters and merging of selected invoices into a single PDF

Impact

Unified daily operations (stock → order → invoice → payment) in a single secure platform, with full financial visibility — installment tracking, expense monitoring, per-salesperson performance — plus automated alerts and backups to reduce manual work and data loss risk.

The challenge

Algerian freelancers and small businesses need legally compliant invoices (factures & proformas) with the right business identifiers (NIF, RC, ART, NIS, CCB), but most rely on manual Word/Excel templates with no verification, no tracking, and no protection against data loss.

The solution

A self-service invoicing platform where each user manages their own professional profile and documents: draft-to-invoice workflows, QR-code-verifiable PDF documents accessible via a public link, a metrics dashboard, and automated, worry-free backups — all built on Spring Security with email-based account recovery.

What I built

• Invoice & proforma generation with line items, VAT calculation, and DZD currency formatting
• Draft system to prepare documents before converting them into final invoices
• PDF rendering (OpenHTMLtoPDF) with a public, QR-code-verifiable link for each document (/verify/{uuid}) to prove authenticity
• Professional profile management with Algerian business fields (NIF, RC, ART, NIS, CCB, wilaya/commune)
• Dashboard with revenue cards, month-over-month trends, and custom date-range charts (Chart.js)
• Secure authentication with Spring Security, password reset via email, and CSRF-protected SPA-style endpoints
• Automated daily PostgreSQL backups (pg_dump) uploaded to Google Drive with email notifications, timezone-aware (Africa/Algiers)
• Algerian phone number validation and French-localized UI/formatting throughout

Impact

Replaced manual, error-prone invoicing with a single trustworthy platform — giving each professional legally structured, publicly verifiable invoices, real-time revenue visibility, and automated backups that remove the risk of losing financial records.

The challenge

Banking and financing workflows were spread across disconnected manual processes, making it hard to follow customer folders end-to-end. Teams needed a secure system that serves both sides: a guichet (customer portal) for submissions and tracking, and an admin back-office for validation, processing, and decision follow-up with full traceability.

The solution

A dual-application architecture with a shared business core: a Guichet app for customers to browse products, submit financing folders, upload supporting documents, and track request progress; and an Admin app for internal teams to review files, validate OCR/document quality, manage product and operational configuration, and monitor lifecycle states from intake to resolution. Both apps are powered by Spring Boot APIs, role-based security, and Dockerized deployments across environments.

What We built (Admin + Guichet)

• Dual front-office/back-office flow: separate Guichet and Admin experiences connected to a shared backend domain model.
• Folder lifecycle management: multi-step folder handling, status transitions, history tracking, and operational comments across teams.
• Customer & order operations: client profiles, addresses, order/folder splits, and document-linked workflows for financing operations.
• Document pipeline: upload and management of customer files, OCR-related verification support, and document status governance.
• Catalog & configuration management: products, categories, characteristics, quantities, regions/towns, points of sale, and global variables.
• Security & access control: authentication, JWT/OAuth-based security, role/permission checks, and protected admin routes.
• Operational communication: integrated notification flows (email/SMS/history) and support for customer follow-up touchpoints.
• Scalable deployment model: Dockerized admin/guichet services with PostgreSQL-backed persistence and object storage integration.

Impact

Replaced fragmented manual processing with a centralized, auditable platform that connects customer guichet interactions to admin decision workflows. The result is faster folder processing, clearer state visibility for all stakeholders, stronger governance on documents, and a more reliable digital experience for both bank teams and customers.

The challenge

French B2B IT wholesale needs a professional digital storefront for resellers and professionals, plus a reliable back-office to manage catalog, quotes, stock visibility, and commercial follow-up. Disconnected tools slow down browsing, quoting, and order preparation.

The solution

A dual-application architecture with a shared business core: a Guichet (customer portal) for product discovery, filtering, cart/devis workflows, authentication, FAQ, and commercial contact points; and an Admin back-office for catalog, operational configuration, and day-to-day sales support. Both sides are connected through Spring Boot APIs, role-based security, and Dockerized deployments.

What We built (Admin + Guichet)

• Dual front-office/back-office flow: separate Guichet and Admin experiences connected to a shared backend domain model.
• Product catalog & search: browse by category/brand/reference, refine filters, grid/list views, and pagination for large catalogs.
• Cart & devis workflow: multi-step checkout journey (cart → delivery → payment), quote preparation, quantity controls, and stock availability checks.
• Customer account access: login/registration, password recovery, and protected private-space interactions.
• Commercial support surfaces: FAQ categories, contact channels, and service commercial entry points for B2B assistance.
• Catalog & operations management (Admin): product/category configuration and operational tools supporting guichet commerce flows.
• Security & access control: authentication, role/permission checks, and protected admin routes.
• Scalable deployment model: Dockerized admin/guichet services with PostgreSQL-backed persistence.

Impact

Delivered a centralized B2B e-commerce experience for IT wholesale in France — helping professionals discover products faster, prepare quotes with clearer stock visibility, and connect customer guichet interactions to admin commercial operations.

The challenge

Algerian retailers need an online store adapted to local realities: DZD pricing, nationwide delivery, and payment methods customers actually use (cash on delivery, bank transfer, CIB and Edahabia cards). Without a connected Admin + Guichet setup, catalog, shipping, and payment flows stay fragmented.

The solution

We built a dual-application e-commerce platform tailored for Algeria: a Guichet storefront for browsing, filtering, cart, and checkout; and an Admin back-office for catalog and operations. Shipping is wired to the Yalidine API for parcel/delivery workflows, while payments support CIB and Edahabia cards alongside cash on delivery and bank/CCP transfer.

What We built (Admin + Guichet)

• Algeria-first storefront: product catalog in DZD, category navigation, search by product/reference/brand, and responsive shopping UX.
• Dual Admin/Guichet architecture: customer-facing commerce connected to an admin domain for catalog and operational control.
• Catalog & merchandising: filters, price ranges, availability sorting, product grids, new arrivals, and partner brand showcases.
• Customer account flows: login/registration, private space access, and password recovery.
• Yalidine shipping integration: API-driven delivery support for Algerian logistics and order fulfillment.
• Local payment methods: CIB and Edahabia card payments, cash on delivery, and bank/CCP transfer options.
• Customer trust & support surfaces: fast delivery messaging, payment-at-delivery options, contact channels, and legal/FAQ links.
• Secure deployment model: Dockerized Admin/Guichet services with PostgreSQL-backed persistence and role-based access.

Impact

Gave Wissal Store a complete Algerian e-commerce experience — from discovery to checkout — with logistics and payment rails that match the local market, and an Admin/Guichet split that keeps operations and customer journeys aligned.
