Core Banking and Legacy Modernisation
Breaking monoliths down into microservices without interrupting operations.
Transactions in milliseconds, security without compromise. Black-belt IT solutions at the forefront of digital finance.
In the financial sector, software development is not merely about writing lines of code — it is about unfailing compliance with a strict regulatory environment (MNB, PSD3, DORA, GDPR). As an experienced partner we understand exactly that introducing a new digital solution or modernising an existing core system must never put daily operations or data security at risk. We build our development processes along the "security-by-design" principle, guaranteeing that the systems we deliver pass the highest-level banking audits smoothly, minimising the legal and operational risks borne by our partners.
For a financial platform, downtime or slowdown is not an option. Secure partnership means, to us, designing robust cloud- and microservice-based architectures that can handle even extreme transaction peaks without data integrity failing for a single millisecond. We do not only develop for today's needs — we create future-proof, flexibly scalable systems that support business growth, whether it is a retail mobile bank, complex credit assessment processes or automated pledge management.
The measure of true partnership is the trust earned and the long-term commitment. We are proud that the most significant players of the Hungarian and international financial markets — from traditional large banks and insurers through specialised state funds to the most agile FinTech platforms — entrust their business-critical digital transformation projects to BlackBelt's expertise.
