- Full-stack web development See the answer
- AWS cloud set-up See the answer
- Payment service integration See the answer
- Cloud cost optimization See the answer
- Law and security compliance See the answer
The answer:
Full-stack web development
Develop apps that actually scale
Build software tough enough to last for years, but flexible enough to service millions of users. Like we did before. Our stack includes React, Node.js, and TypeScript along with our custom frameworks and AWS. It made many products competitive.
The answer:
AWS cloud set-up
Make the cloud your advantage
Be sure the cloud boosts the product instead of breaking it. Over 60+ certified AWS engineers here can help you migrate to the cloud, create a hybrid on-prem-to-cloud setup, or develop cloud-native apps.
The answer:
Payment service integration
Adopt popular services
Using pre-made components development is in our DNA. Benefit from our tested workflows that make integrations error-free. You can soon connect to payment platforms, transaction gateways, single sign-on modules, and more.
The answer:
Cloud cost optimization
Shield yourself from big bills
The cloud is a friend — if you set it up pretty well. Ask our DevOps how they cap total spending for cloud architecture from dozen of thousands to only a few. They actually do that. They will help you keep the project optimized for low cloud cost from the start.
The answer:
Law and security compliance
Experience shared responsibility
Working under strict regulations? We know and follow them. GDPR will protect your users and the product will have security-certified technology, centralized identity and authorization management
“They’re really becoming a part of our organization”
As said by Bart van Muijen, GoConnectIT’s CTO, who’s been with us for 3 years. Connect with the software experts he rates as ★5 collaborators.

Growth-oriented development
Fintech case studies
The market’s pace of change is challenging. The Board has unbending expectations. And then you have your users who can switch their platform if there are too many bumps.
You need a forward-thinking partner who knows how to develop at a scale from a national to a multi-country level. These companies needed that too — see how much they achieved.

Frequently asked questions
What type of financial institutions and fintech software companies have you worked with?
For now, we can only mention projects with:
- A traditional bank that moved technology onto the AWS cloud with us. We used React, Serverless, and Node.js. Our design team later helped to rebrand their product’s UX/UI.
- A fintech with a B2B lending platform we supported with business logic work and development in React and Node.js plus Python.
- Another fintech called Energy Web (case study). They asked us to build a solar battery grid management app based on AWS, Ethereum, and Node.js.
- And yet another one called Arantio, where the founders flipped an intranet app into a payment processing platform for companies granting employee benefits
That experience plus 10 years of know-how can work for you.
We’re open to doing web development, business analysis, and cloud engineering work for traditional banks and fintech scale-ups. Representing a fintech software development company? Sure, let’s team up.
And if you need consulting services to failproof your strategy, guess what — your friend here can help too.
What services for the financial industry can you integrate?
We had success with connecting 8+ fintech-specific services that offer:
- EU, US, UK, and international payments in EUR with the set-up needed to earn the SEPA certificate
- International transfers in dozens of currencies
- 4 different payment gates that allow fintechs to accept debit plus credit cards, PayPal-like instant payments, and Google and Apple Wallet transfers
Simply put, expect your product to get packed with features all fintechs desire. Or as Microsoft would say it — “Introduce innovative business solutions today!”
How many developers from your software development company can I have in my team?
Let’s face it. You could use a technology partner that lifts you throughout years, and that’s why we’re ready to offer you a product team of 2 to dozens of experts.
One client that stayed with us for 6 years grew the team to 20 professionals.
You’ll also have the freedom to scale up or down depending on workload, and to delegate a project in full by adding one of our very convincing PMs to the group.
