Résumé Exécutif

A refrigeration-services company was running customers, quotations, invoices, stock and technician work across paper, memory and disconnected files. I was brought in for four weeks, solo, to fix that. What shipped is a Laravel platform where a quotation, the invoice it becomes, the stock movement it triggers and the technician who executed the job are the same connected record, not four separate ones someone has to reconcile by hand.

Context

Fractal Tech brought me in to build the operating system for a real refrigeration-services SME between July and August 2025: a company that sells, quotes, delivers and invoices refrigeration equipment and interventions, and had been doing all of it without a shared system. Four weeks, one developer, one client who needed something that actually worked on day one — every data-modelling decision had to be right the first time, because there wasn't slack in the schedule to redo the relational core halfway through.

My role and ownership

• Requirements analysis and workflow mapping
• Merise/UML relational data modelling
• Laravel backend and Blade interface
• Authentication and role-oriented access
• Deployment, documentation and user handoff

Personal contribution

Requirements, architecture, data model, backend, frontend, deployment, documentation and handoff.

Le Problème

None of this was a technology failure so much as the predictable result of a business that grew its operations faster than its record-keeping, which is most SMEs at this exact stage. Quotations were typed fresh each time because nothing linked back to a customer's history. Invoices existed with no reliable trace to the job or the stock they consumed. Technicians' fieldwork wasn't visible to the office, and the office's paperwork wasn't visible to technicians. A stock count meant someone walking to the shelf, because nothing tracked what a completed job had actually consumed.

La Solution

Everything hangs off five connected states rather than five independent modules that happen to share a login page: a customer record establishes identity and history; a quotation captures scope and price against that customer; an order/delivery step preserves execution continuity once the quotation is accepted; an invoice closes the loop financially and stays permanently linked back to the job that generated it; and a history layer makes every one of those states searchable across customers, documents and interventions.

Stock movements attach to the same relational core: an intervention that consumes a part writes a stock-ledger entry, not a manual adjustment someone has to remember to make later. Technician task assignments and operating expenses follow the same pattern. The result is that a manager can open one customer and see their full quotation-to-invoice history, the stock consumed against it, and which technician handled it, in one place, without cross-referencing five different documents. The sequence below is exactly what ships in the delivered system:

Ingénierie

Laravel 10 and PHP 8 over anything more exotic — a four-week SME engagement needs a framework where the distance from data model to shipped feature is short, not a chance to experiment with something unproven. MySQL for transactional integrity on financial documents. Blade instead of a separate SPA: it kept delivery cohesive, ran comfortably on the ordinary office hardware the client actually has, and still supported distinct views per role without the overhead of a second deployment target under a four-week clock.

Le Résultat

The client went from five disconnected record types to one searchable operational history, with management able to see documents, stock and field activity in the same place for the first time. That is the actual deliverable — not a UI, a reconciliation problem that stopped existing. The expanded source shows 33 migrations, 32 controllers and 28 models across 120 Blade views, which is the shape of a real relational business system, not a demo CRUD app with a login screen bolted on.

Verified evidence

• Real SME delivery recorded in the CV
• 18+ captured operational modules
• Desktop and mobile responsive captures
• Expanded source inventory includes 33 migrations, 32 controllers, 28 models and 120 Blade views
• Original handoff included technical documentation and a user guide

Current limitations

• The later expanded source requires a dedicated hardening release before public deployment.
• Automated tests are insufficient for document transitions, permissions and stock reconciliation.
• Several screenshots use sparse synthetic data and prove interface scope more than production volume.
• The public case study distinguishes the original delivery from later experimental expansion.
