One developer. Full ownership.
[01] Profile
I'm Patiphan Mahamat, a full-stack product engineer in the Netherlands with over six years of professional experience, working as Fantomu.dev. I work with SMEs, startups, and product teams that need reliable technical execution, either as a dedicated project partner or embedded within an existing team.
Clients hire me because the work gets done without hand-holding, communication is direct, and the codebase I deliver is one they can actually maintain. No junior developers learning on your project, no account managers, no inflated proposals, just clean code and clear delivery.
Alongside client work, I build my own SaaS products, a deliberate practice that keeps my technical instincts sharp and shows full-stack ownership from architecture through to production.

[02] Working style
Every engagement starts with a scoping conversation, not a sales call. Work is broken into milestones with clear deliverables. You get a shared project workspace and a staging environment throughout. Nothing ships to production without a review.
Async-first: most communication happens over email or a shared channel. You get a written progress update every week, not only when things go wrong. Video calls are used for decisions, not status reports. Response time during a project: within 2–3 business days.
The best-fit clients know what they want to achieve but don't need to specify every technical detail. You need a clear business goal and willingness to give feedback, not a deep understanding of Laravel. If you're looking for the cheapest quote, this probably isn't the right fit.
[03] Career
Built and maintained e-commerce integrations for Magento 2, Shopify, and Lightspeed across retail and wholesale clients
Developed SaaS products from early architecture through production and scaling
Integrated ERP and warehouse management systems with web storefronts and internal tooling
Managed Linux server infrastructure for production applications (VPS, Docker, Nginx)
Worked embedded within product teams as a developer and technical lead
Building own SaaS products alongside client work
[04] Tech Stack
A practical toolkit built over 6+ years of shipping real projects, not a buzzword list.
[05] Clients
Feedback from businesses we've worked with.
We had a working integration between Shopify and our warehouse system within three weeks. No miscommunication, no delays, just a clean result. Exactly what we needed.
The codebase we received is something our team can actually work with. Well-structured, documented where it matters, and production-ready from day one. That's rare.
What stood out was how little hand-holding was needed. We described the business problem, and the right technical solution came back, on time and within budget.

Most projects start with a 30-minute discovery call. No commitment, just a direct conversation about what you need.
