Hello 👋🏿
I am Mame A. FAYE
Senior Back-End Developer — PHP / Symfony / API
A Senior Back-end Developer with 9 years of PHP experience, 7 of them on Symfony. I specialize in building secure, high-performance APIs (API Platform) and handling high-volume data pipelines, with hands-on production experience: version migrations, API security hardening, async processing (RabbitMQ, Mercure), and payment integrations (Stripe, Orange Money). Alongside client missions, I'm building my own SaaS products: CONVOY, an agentic e-commerce platform built on the Model Context Protocol (MCP), and t-ket, a ticketing SaaS for facility management already used by a first client in production. Available for freelance or full-time missions — feel free to book a call.

Multi-tenant SaaS for ticketing and work-order management in facility management and construction, replacing scattered exchanges over WhatsApp, email and Teams. First client already in production.

Founder and sole developer of t-ket, a multi-tenant SaaS for ticketing and work-order management aimed at facility management and construction, replacing scattered exchanges over WhatsApp, email and Teams. I designed and built the entire architecture and backend, with occasional help from a freelance front-end developer: a full domain model (sites, buildings, zones, rooms, roles, teams), a 6-status Kanban board, multi-view planning, .ics and .xlsx exports, and automatic work-order ingestion by email. I also built the SaaS billing engine: per-session seat counting, overage handling with budget safeguards, price lists, capped discounts and a white-label mode for partners. The platform is in production with its first client.

Multi-tenant SaaS platform positioned as a "backend for LLMs": agentic e-commerce through the Model Context Protocol (MCP) and WebMCP, letting AI agents interact with merchant catalogues and tools.

Co-founder and CTO of CONVOY, a multi-tenant SaaS platform positioned as a "backend for LLMs": it exposes merchant catalogues and tools to AI agents through the Model Context Protocol (MCP) and WebMCP, enabling agentic e-commerce. I defined the technical architecture (Symfony / API Platform for the domain, FastMCP in Python for the MCP servers) and designed seven exposure surfaces (Web, App, Browser, Shopify, Embed, Page, AI) along with generic tool naming conventions reusable across clients. I also handled the first prospects and client onboarding in the e-commerce and legaltech sectors.

TrainingFinance Management
Sep 2024 - July 2026 | OPCO Mobilités, Boulogne-Billancourt, France

Lead backend developer on the member management project at OPCO Mobilités, a skills operator in the transport and logistics sector.

Within a team of 7 developers led by 2 project managers, I took charge of strategic missions including migration from PHP 7 to PHP 8, Symfony 6.0 to 6.4, and ApiPlatform 2.7 to 3.4, with complete preparation for Symfony 7 and ApiPlatform 4. Implementation of unit and functional test infrastructure (coverage from 0 to 70%), deployment of a notification monitoring system with Teams alerts, API route security and removal of clear JWT tokens, progressive migration to ApiPlatform 3+ Processors/Providers (70% completed), and SOLID-oriented refactoring guided by SonarCube. Development of key business features: CERFA v14 integration for apprenticeship contracts, training agreements, employee import, Qualtrics surveys, invoice generation, GED/ERP caching, and migration of identifiers to UUID in preparation for PostgreSQL transition. Resolution of complex issues (Mercure instability, conditional validations, dead code identification) and facilitation of tech-radars, mob-reviews, and estimation workshops.
