FinTech and e-commerce development

We build payment flows and online shops that hold up in practice: a checkout that does not lose the buyer on the last step, and a clear record behind it of what has actually been settled. Card data travels to the payment provider; it never reaches our code.

The merchant dashboard, webhooks and the integrations with KYC, AML and accounting are planned together rather than bolted on later. Product pages are rendered on the server, so Google and answer engines see price and availability without waiting for a script.

Requirements and compliance

Payment flows, currencies, markets and what the payment provider demands.

Architecture

Data model, webhooks and the line card data never crosses into our system.

Development

Checkout, merchant dashboard and integrations on Next.js 16 and TypeScript.

Testing and launch

Sandbox payments, failure scenarios and reconciliation checked before going live.

A payment has to succeed even when something goes wrong.

Fintech and e-commerce: payments that hold up

We build stores and payment flows where money is traceable and failure cases are thought through: repeat payment, refund, partial delivery, currency conversion. We integrate Stripe, Montonio, bank links and crypto payments.

Speed translates directly into money here: every extra second in checkout costs orders. So we measure LCP and INP on real devices, not only in the lab.

The data side matters just as much: stock, ERP, accounting and CRM connected, so nobody has to retype an order by hand.

FinTech and e-commerce questions

No. We write software and build the integration. The licence, the contract with the payment provider and the regulatory side stay between you and the regulator.

We build so that card data never passes through your server: hosted fields and tokens from the provider. Certification itself is an audit question, not a development one.

Yes. We often start by replacing the checkout and the integrations and leave the rest of the shop untouched for now.
