As a freelance developer, I design and build SaaS, CRM/ERP and e-commerce platforms end to end — from back-end architecture to modern interfaces, backed by 10 years of web development experience.
01 — About
I turn complex business needs into robust, maintainable applications that people actually use.
// mohamed.abidi
A web developer since 2016 — and in IT since 2013 — I have built multi-partner sales CRMs, e-commerce platforms, microservice ecosystems and complete SaaS products, first in agencies and then within the U-Smile ecosystem (Base Développement / Digitrends).
Now working freelance, I support companies such as Activ 1926 (full-service renovation) on their business-critical tools while building Karbonic, my own SaaS product. My approach: understand the business before writing code, ship fast, and leave behind clean, documented codebases.
Laravel/GraphQL APIs, Vue 3/Nuxt front-ends, SQL & NoSQL databases, realtime, payments, deployment — I cover the whole chain.
Applications used every day by consultants, field technicians and end customers — not demos.
Builder of SaaS products (compliance, carbon, trading) with OCR and AI-powered analysis (Mistral, OpenAI). I think about usage, billing and growth — not just code.
