Remote-first · since 2019
Built on the equator. Shipped worldwide.
QMT works remotely with startups, SMEs, and agencies — wherever you are. We turn manual processes and disconnected tools into software that talks to itself: apps wired to your payment, CRM, and internal tools, dashboards that unify data from many sources.
Our approach is analytical and ROI-oriented — every technical decision is measured by its impact on your operations, with industry security standards (OWASP) and clean documentation.
“At culmination, the sun leaves no shadow. That's how we work: clear, measured, no hidden costs.”

The person behind QMT
Deddy Febriyadi
Founder & Lead Engineer · Pontianak
I'm Deddy — founder and the person who writes the code behind QMT. My focus: web & PWA apps on Laravel, workflow automation with n8n + WhatsApp API, and system integration I run myself on VPS/Docker. The case study below — GYM INDIE — I built end-to-end: architecture, code, all the way to its production server. Need one engineer who knows the whole stack, or a studio team for larger scale? Both go through me.

Invoiced in USD/EUR via Wise or Stripe, milestone-based; Upwork & escrow welcome. You own the code and IP on final payment, and I sign an NDA before kickoff on request.
