Fintech products built for trust and scale
Specialist work falls apart when it never leaves the demo stage. Anything in production still needs auth, data handling, monitoring, and an interface people can use.
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
- Documented handover and runbooks
- Help getting it deployed
How engagement works
Projects are shaped around fintech startups and financial product teams, so scope stays realistic, the first release comes quickly, and there is room to improve without a rewrite.
- 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.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. You see progress on the critical path every week.
- 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.
- 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
- 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.
- 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.
- 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.
- 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.
