REVIEWS
We wanted to enhance our shipping solutions by migrating our desktop-based platform and its users to a new web application. Good KPIs met our expectations, generating plans for future collaboration with Eastern Peak.
interview on Clutch
We had a development challenge, as well as a business one. We needed quality people quickly, so we decided to approach Eastern Peak. The results were excellent and we were able to exploit the full potential of the IoT.
interview on Clutch
Eastern Peak assumed responsibility for their results and never tried to deflect it. They stood behind their promises and were very pragmatic. We have received input on app development as well as on our general business model, which helped a lot.
interview on Clutch
We needed to find people who were experienced specifically with startup schedules. Most of the people I’ve worked with had experience of five or six startups, and they’re in their mid-20s. These guys have a good reputation, and I just got very lucky to work with them.
interview on Clutch
They gave me the knowledge, expertise, and experience I needed to launch everything from the beginning and to support it further. They’re like a partner in terms of thinking and creating new concepts, new features, and new ideas.

FAQs on Banking Software Development
1. Do you build both mobile banking apps and core/back-office systems?
Yes. We deliver mobile banking app development as well as web back-office, admin, and core-integration layers, either as a single product or as parts of a wider digital banking platform.
2. How do you handle security and regulatory compliance?
Security and compliance are designed in from the start: encryption, MFA, audit logging, and adherence to PCI DSS, PSD2/Open Banking, GDPR, and KYC/AML requirements relevant to your market.
3. Can you integrate with our existing core banking system?
Yes. We have integrated with core banking platforms, card processors, and payment gateways, including legacy systems, using their APIs or middleware, so you avoid a risky full replacement.
4. How long does a banking software project take?
It depends on scope. A focused mobile banking app can reach a first release in a few months; a full platform takes longer. We define scope and a roadmap during a product discovery phase.
5. Do we own the code and IP?
Yes. You get full ownership of the source code and IP, with complete repository access, no vendor lock-in, and no mandatory monthly platform fee.
