Pragmatic software engineering: ship, document, reduce risk. Whether you are a non-technical founder or a team lead, Mathieu42 brings senior discipline without heavy enterprise process.
Over ten years of full-stack engineering shipped to production for startups and product teams — marketing sites, e-commerce, business apps, and API integrations.
Professional liability insurance covering the assignment and deliverables. Certificate included with the quote — a secure, transparent framework for working with your business.
On-site around Perpignan and across Pyrénées-Orientales (66). Remote engagements across France and internationally — same scoping, follow-up, and delivery standards.
Working software, traced decisions, and enough quality to grow — useful tests, light CI, no ceremony.
Business goal → technical breakdown → incremental delivery → review. You always know what is in prod and what remains.
From the initial call to production—same method for a website, an audit, or an MVP.
You share context, goals, and constraints. I recommend the right solution (website, audit, MVP, maintenance…) with no obligation.
Written scope, recommended stack, milestones, and an indicative range or fixed fee. Free quote with no obligation—you approve before the first billable day.
Repo/tool access, shared plan, and a first visible milestone—no radio silence.
Web, software & SaaS, AI, and mobile. Open the expertise that matches your project, then I scope the next step with you.
Conversion-focused sites, web apps, and e-commerce — shipped with performance and SEO foundations.
