Payment Expert

Payment systems should be the last thing your customers think about—and the first thing you can trust. With deep experience across payment service providers (PSPs) and PCI Level 1 environments, I architect high-volume payment solutions that process millions in transactions with zero friction, ironclad security, and enterprise-grade reliability.

Payments. Invisible. Relentless. Reliable.

When a customer clicks "pay," they expect one thing: success. No delays. No errors. No friction. I build payment systems that deliver exactly that—millions of times over. From high-volume transaction processing to complex multi-currency flows, my architecture ensures every payment is fast, secure, and invisible to the user.

Millions in Revenue Protected.

Leading the Payment division at ScaleFast™, I drove payment failures down to near zero—recovering over 15% in transaction success rate. Before that, I worked across multiple PSPs, leading PCI Level 1 compliance processes and building payment infrastructure that passed the toughest audits. Results aren't promised. They're delivered.


Joseba Mirena Anti-Fraud Expert

PCI Level 1. Built From Experience.

I've led PCI compliance processes from start to certification. I know what auditors look for, what keeps them satisfied, and what keeps your data safe. My payment architectures are built with security at every layer—tokenization, encryption, audit trails, and segregation of duties. Compliance isn't a checklist. It's a mindset I've lived for years.

Gateway Agnostic. Integration Ready.

Your business shouldn't be locked into a single payment provider. I build systems that work seamlessly with Stripe, Adyen, Braintree, PayPal, or custom gateways—giving you flexibility without complexity. Need multi-currency? Global compliance? Real-time reconciliation? Already built. I design payment layers that sit on top of your existing stack, making it smarter, faster, and infinitely more reliable.


High-Volume Ready

Hundreds or millions of transactions? My architecture scales without breaking. Growth is the plan, not the problem.

PCI Compliant by Design

Security isn't bolted on—it's built in. Every layer of my payment architecture meets and exceeds PCI standards. I've led Level 1 audits. I know what passes.

Multi-Currency. Multi-Provider.

Global business needs global payments. I build systems that handle any currency, any gateway, any region—seamlessly.

Real-Time Reconciliation

Every transaction tracked, logged, and matched. No black holes. No missing funds. Complete financial visibility.

Fast, secure, compliance. Payments that just work.

Payment Technology: What People Ask

If you need anything, don't hesitate to contact me—I'm always happy to help!

How do you handle high-volume transactions?

With architecture designed for scale from day one.

I build payment systems that handle traffic spikes, batch processing, and real-time flows without breaking. Load balancing, queuing, and horizontal scaling are built in—not added as an afterthought. Whether you process 100 or 10 million transactions, the system behaves the same: fast, reliable, invisible.

Can you integrate with my existing payment provider?

Almost always. I don't force you to change what works.

My payment layers sit on top of your existing infrastructure—whether you're using Stripe, Adyen, Braintree, PayPal, or a custom gateway. I've worked with multiple PSPs and know their quirks. I integrate without disruption, making your current system smarter, not replaced.

What about PCI compliance? Is that handled?

Built in from the foundation, not an afterthought. I've led Level 1 processes.

PCI compliance isn't optional—it's essential. I've led PCI Level 1 compliance from start to certification, working directly with auditors and remediation teams. My payment architectures are built with security at every layer: tokenization, encryption, secure data handling, and audit trails. You don't need to worry about compliance. I've already handled it.

How do you reduce payment failures?

By understanding why they fail in the first place.

Leading payment teams at ScaleFast™, I reduced payment failures by over 15% by analyzing every decline, optimizing retry logic, and working directly with acquirers to resolve friction points. Most payment failures are fixable—if you know what to look for. I do. And I fix them.

Do you handle multi-currency and international payments?

Absolutely. Global business needs global payments.

I build systems that handle multiple currencies, cross-border transactions, and region-specific payment methods—from cards to wallets to bank transfers. Your customers pay how they want, in their currency, with zero friction. That's how you grow globally.

What about fraud prevention? Isn't that connected?

It's inseparable. That's why I lead both.

Payments and fraud prevention are two sides of the same coin. I architect both because they need to work together—in real-time, in parallel. Blocking fraud shouldn't block customers, and approving payments shouldn't approve criminals. My systems balance both, invisibly, at scale.

Can you build a custom payment gateway from scratch?

If you need one, yes. But most businesses don't.

Building a custom gateway is possible—I've done it—but it's rarely the right answer. Most businesses are better served by integrating with proven providers and layering intelligence on top. I'll tell you honestly what your business needs, not what looks good on a resume. Trust is earned, not sold.
