Fintech products built for trust and scale

We prototype the risky integration first, then sort out auth, data contracts, evaluation, and monitoring before spending time on polish.

Most people who reach this page are fintech startups and financial product teams. Secure fintech software development covering dashboards, payments, compliance-minded architecture, and AI-assisted workflows.

What you get

  • Payment and billing systems
  • Secure auth and audit trails
  • Admin and customer portals
  • API-first product platforms
  • One studio accountable for the result
  • Design and engineering on the same schedule
  • Support available after launch

How engagement works

As your fintech software development, we run a shared backlog, design reviews, and engineering sprints, and you keep one point of contact throughout.

  1. 01

    Discover

    Goals, constraints, data sources, and success metrics, all settled before we touch architecture or prompts. The work for teams in New York stays tied to the outcome you asked for.

  2. 02

    Design

    System design, AI/tool boundaries, interface direction, and interaction prototypes. You see progress on the critical path every week.

  3. 03

    Build

    Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. Nothing here waits on a handover between separate teams.

  4. 04

    Launch

    Ship, monitor, harden, and keep improving models, tools, and product after go-live. On fintech software development projects we favour practical architecture over trendy defaults.

How we build it, and why

The stack is chosen per project, not applied from a template. For fintech software development work these are the defaults, and the reason each one is on the list.

Next.js
server rendering and static generation in one framework, so marketing pages stay fast and app routes stay dynamic
NestJS
structure and dependency injection on the backend, which keeps a growing API from turning into a pile of route handlers
PostgreSQL
relational integrity for data you cannot afford to get wrong
Stripe
payments, subscriptions, and the tax and invoicing edge cases you do not want to build
AWS
the services you grow into, once a managed platform stops being enough

What the first weeks look like

  1. Week 1

    Spike the risky part

    We build the thinnest possible version of payment and billing systems against your real data. If it is going to be a problem, it is better to know in week one than week six.

  2. Weeks 2-3

    Harden the integration

    Auth, rate limits, error paths, and the data contract. This is the work that separates a demo from something you can leave running.

  3. Weeks 4-6

    Wire it into the product

    The fintech software development stops being a standalone service and becomes a feature people use, with the interface and permissions that implies.

  4. Ongoing

    Evaluate and tune

    Behaviour gets measured against cases you care about, and we tune from that rather than from impressions.

Weighing up your options

There are three realistic ways to get this built. Each is the right answer for someone.

A solo freelancer

Cheapest per hour and fine for a contained task. The risk on fintech software development is breadth — one person covering design, backend, infrastructure, and launch usually means one of them is weak, and there is no cover when they are unavailable.

A local agency in New York

Same timezone and a face to meet, which genuinely matters for some teams. You are also paying New York companies hiring on portfolio proof and production AI. rates for the whole team including the layers that never touch your fintech software development, and a local shortlist is a small shortlist.

Arcode

A small senior team. The people who scope the fintech software development write the code, you get weekly demos instead of status decks, and the engagement ends when the thing is live and handed over.

Working with teams in New York

New York companies hiring on portfolio proof and production AI. We work with clients in New York remotely and keep overlapping hours in EST/EDT. We usually collaborate in English.

How we work with New York teams

New York is on ET, so our afternoon covers your morning. In practice that means a scheduled daily window for anything that needs a conversation, and written updates waiting when you start.

What New York clients usually need

New York briefs cluster around fintech, media, and B2B SaaS. A lot of the work is replacing a prototype that got a company to revenue but cannot carry the next stage of growth.

Contracts, data, and compliance

Contracts are usually US contractor agreements with IP assignment and an NDA. Fintech projects get SOC 2 evidence and audit logging scoped into the build rather than retrofitted before a raise.
