CUSTOM DEVELOPMENT · DEVOPS · FINTECH INTEGRATION

Engineering capacity, on demand — for brokers and fintechs.

You don’t always need a platform. Sometimes you need a specific thing built, integrated or automated — a custom module, a PSP connector, an internal tool, a CI/CD pipeline that stops Friday deploys breaking Monday. Prixim Engineering provides the dev and DevOps capacity brokers and fintechs need, without hiring a team: custom development, integrations, automation, code audit and release management.

For fintechs especially

Fintech integration catalogue

Fintechs live on integrations. We build and maintain the connectors that let your product talk to banks, PSPs, wallets, KYC, ledgers and liquidity — with idempotency, retries and reconciliation built in.

Payments & PSPs

Acquiring, wallets, ramps

Connector layer with cascade retry, webhooks and recon — the same orchestration our gateway runs.

AdyenCheckout.comNuveidLocalRapydSkrillSticPayMoonPay
Banking & EMI

Accounts, payouts, FX

Multi-currency account, payout and FX connectors via EMI/bank APIs, with safeguarding-aware structures.

WiseAirwallexCurrenxieFirstPartyRevolutFireblocks
Ledger & core

Double-entry, wallets

Ledger and wallet engines with idempotency, atomic settlement and audit — the heart of a money product.

Code audit — a prioritised remediation ledger

Inheriting a codebase? Before you build on it, know what’s in it. Our audit produces a severity-ranked ledger with effort estimates — so you fix what matters first, not what’s loudest.

How to engage

Three engagement models

MODEL 01

Fixed-bid project

A defined build, a known price

  • Scoped spec → fixed quote
  • Milestone deliveries
  • Code audit + handover included
  • Best for: one integration, one tool

Scope a project
MOST FINTECHS PICK MODEL 02

Dedicated pod

An embedded engineering team

  • Cross-functional pod (dev + DevOps + QA)
  • Your backlog, our velocity
  • CI/CD + release mgmt included

  • Monthly, scalable squad size
Monthly retainer
Request a pod
MODEL 03

Advisory + audit

Engineering plugs into the platforms we already run

Because we deploy and operate MT5, cTrader, DXtrade, TradeLocker, MatchTrader and PriximTrader, our engineers build integrations that fit the real systems — not a theoretical API.

Frequently asked

Code & DevOps, answered plainly

Do you only work with brokers, or fintechs too?

Both — the page is built around the two audiences you named. Brokers tend to need integrations (PSP, CRM, liquidity, reporting) and DevOps for their platform estate; fintechs tend to need a dedicated pod building product, plus the ledger/wallet/KYC integration layer. The same code standards, security gates and release discipline apply to either.

What does “DevOps” actually include here?

The pipeline board in the hero is ours to run: CI/CD with gated stages (lint → test → SAST/DAST → signed build → stage tick-test → canary prod), infrastructure-as-code (Terraform/Ansible), containerisation (Docker/Kubernetes with SBOMs), observability (metrics/logs/traces/alerting), secret management, on-call with runbooks, and blameless post-mortems. Environments are dev/stage/prod with ephemeral previews.

Can you audit code we already have?

Yes — that’s Model 03 and a common starting point. The audit covers eight areas (security, data integrity, performance, reliability, test coverage, maintainability, DevOps, compliance) and outputs a severity-ranked remediation ledger with effort estimates, so you fix what matters first. Data-integrity and security findings are rated Critical because in money software they’re the ones that bite.

How do you handle releases on a live trading system?

Six gates and immediate rollback. Nothing reaches prod without lint, tests, security scan, signed build, and a stage tick-test against live feed; prod deploys are canary, off-peak, with feature flags and hot rollback armed. It’s the same change discipline the dealing desk uses for swap/feature/routing changes — because a Friday deploy that breaks Monday is how brokers lose clients.

Which integrations do you build most?

The fintech catalogue above: PSP/payment connectors (Adyen, Checkout.com, Nuvei, dLocal, Rapyd, Skrill, SticPay, MoonPay), banking/EMI payout+FX (Wise, Airwallex, Currenxie, FirstParty, Revolut, Fireblocks), ledger/wallet engines (Numary, Formance, custom event-sourced), KYC/screening (Sumsub, Onfido, Veriff, Chainalysis, Elliptic, TRM), liquidity/FIX (oneZero, PrimeXM, LMAX, Cboe FX, Binance, Coinbase), and data/reporting feeds.

Do you build in our stack or yours?

Either. We work inside your existing stack (language, cloud, CI) or build into ours — and because we deploy MT5, cTrader, DXtrade, TradeLocker, MatchTrader and PriximTrader, our integrations fit the real systems rather than a theoretical API. Handover is documented and componentised so your team can maintain it.

What’s a “dedicated pod”?

Model 02: a cross-functional embedded team (developers + DevOps + QA) working your backlog at a steady velocity, with CI/CD and release management included, monthly and scalable in squad size. It’s engineering capacity without the hiring, churn and overhead of building a team — the model most fintechs pick when they’re shipping continuously.

Is code security reviewed before it ships?

Always, as a pipeline gate — SAST, DAST, dependency CVE scanning and secrets detection run on every build, and Critical/High findings block the merge. For inherited code, the audit’s security and data-integrity rows are rated Critical with exploit paths and fixes. Money software doesn’t get to ship insecure.

Can you take over an existing pipeline or codebase?

Yes — audit first (Model 03), then harden the pipeline and remediate the ledger, then move to a pod or fixed-bid work as needed. Takeover is staged so nothing breaks while you assess; the audit ledger is the shared plan.

How is it priced?

Fixed-bid projects are scoped to a spec and quoted; dedicated pods are a monthly retainer scaled to squad size; advisory/audit is per engagement. All include the code audit and handover documentation appropriate to the model — you get a written proposal after discovery, no open-ended billing.
