I’m rolling out a new payments stack and need a specialist who lives and breathes PSP integrations. The goal is to wire several providers into a single cashier, route transactions intelligently (cascading / fail-over), and do all of it through the Praxis platform so my forex operation can process smoothly across multiple jurisdictions.
Here’s the landscape you’ll be walking into: we already have merchant accounts waiting, a partial Praxis setup, and a development team that can expose any hooks you need. What we do not yet have is the deep PSP know-how to stitch everything together—gateway APIs, alternative payment methods, risk rules, card presentment logic, the works—and then tune it for high-risk traffic without throttling approval rates.
Your brief is straightforward:
• Connect at least three PSPs inside Praxis and prove live processing in sandbox and production.
• Configure dynamic routing so declined transactions waterfall to the next provider automatically while tracking which route converted.
• Build or refine the cashier UI/UX so deposit, withdrawal, and refund flows feel seamless for our traders.
• Supply clear, developer-friendly documentation and a rollback plan so the in-house team isn’t left guessing.
Success is measured by: 1) ≥ 95 % uptime across all routes, 2) measurable lift in acceptance rate once cascading is active, 3) settlement files that reconcile to the cent, and 4) passing compliance review (PCI DSS scope stays within Praxis).
we move fast and respect expertise. A background in forex is essential—the terminology, velocity, and chargeback profile differ from standard e-commerce, and we need someone who already understands that. Experience with iGaming or other high-risk verticals is a bonus but not required.
If you’ve previously implemented multi-acquirer routing inside Praxis or a comparable cashier, let’s talk. Point me to a specific project or metrics you improved, and include the PSPs you integrated. I’m keen to start as soon as you can clear any NDAs and jump into our staging environment.
