Payment engineering · since 2018
EMV Level 3 certifications, mPoC, Android payment apps, unattended commerce, and custom payment development — shipped for processors, ISVs, and acquirers across 5 regions.
Where we focus our team's depth — and what we ship every day for payment companies operating at scale.
From scoping to acquirer sign-off, we run the full certification lifecycle for processors across the US, Canada, LATAM, Caribbean, and Europe. Existing acquirer relationships clear bottlenecks before they form.
Turnkey, hardware-agnostic platforms for vending, EV charging, parking, petroleum, and car washes. Certified stacks on PAX, Ingenico, and Verifone, with MDB integration and field-ready Android terminals — engineered for uptime.
We scope, design, and build in-house. C, Android, iOS, embedded, and cloud — all with payments DNA. From Clover apps and PAX terminals to multi-region acceptance stacks, we ship outcomes, not tickets.
A focused, experienced team that integrates with yours — and delivers payment outcomes that move the needle.
Our core competency is integrating and enabling payments — globally, not just in the US. Deep stack security knowledge moves hand-in-hand with everything we ship.
We add our technical know-how to your projects while staying a value-added resource to your existing team and infrastructure — not a replacement for it.
We know payments, devices, certifications, and modern emerging technologies. Why start from zero when you could be off to a running pace from day one?
Extensive relationships with all major acquirers across the US, Canada, Europe, and Latin America. A proven track record that clears bottlenecks before they form.
Packaged engagements that turn our hardest-won capabilities into fixed-scope, fixed-outcome programs.

Three recent engagements — what came in, what shipped, and how long it took. Every project ends with working software in production, not a postmortem.
An ISO out of the Midwest needed a custom payment application built on Android — from concept to a first live customer transaction. We scoped, built, and shipped end-to-end. They were taking real card payments in production faster than most shops finish discovery.
A high-growth unattended operator needed L3 certification on Sunmi hardware against TSYS Sierra. They'd been quoted seven figures elsewhere and needed it shipped in months. We built the application, ran full FIME / ICC suites in-house, and shipped with time to spare for their rollout.
A European fuel operator needed L3 certification on outdoor pay-at-pump hardware against a notoriously strict processor spec. They came to us after a third party stalled. We ran a full pre-cert pass, caught the issues their previous vendor missed, and hit the original deadline.
Tell us what you're building. We'll tell you what it takes to get it certified, integrated, and shipped — and you'll hear back from a payments engineer, not a sales rep.
