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. Nothing here waits on a handover between separate teams.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. On fintech software development projects we favour practical architecture over trendy defaults.
- 03
Build
Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. The work for teams in Amsterdam stays tied to the outcome you asked for.
- 04
Launch
Ship, monitor, harden, and keep improving models, tools, and product after go-live. You see progress on the critical path every week.
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 Amsterdam
Same timezone and a face to meet, which genuinely matters for some teams. You are also paying Amsterdam teams looking for international remote talent. 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 Amsterdam
Amsterdam teams looking for international remote talent. We work with clients in Amsterdam remotely and keep overlapping hours in CET/CEST. We usually collaborate in English/Dutch.
How we work with Amsterdam teams
Amsterdam is three to four hours behind us, so the afternoon is fully shared. English is the working language throughout, which removes the usual friction on documentation and handover.
What Amsterdam clients usually need
Dutch briefs are often international from day one — products launched across several European markets at once, which pushes multi-currency, multi-language, and payment routing into scope early.
Contracts, data, and compliance
GDPR applies from the start, with EU-hosted data by default and a DPA provided as standard. We invoice in EUR, using reverse-charge VAT for VAT-registered businesses.
