# Banking Software Development for European Banks | DevsReady > DevsReady builds banking software for banks and their system integrators: corporate and retail digital banking, virtual branch forms, order signing, back-office workflows and audit trails, with Java, Spring Boot, React, Kafka and Oracle. URL: https://devsready.io/banking-software-development Last updated: 2026-10-18 Services ## Banking software development DevsReady builds banking software for banks and the system integrators that serve them: corporate and retail digital banking, virtual branch forms, secure order signing, back-office workflows and audit trails, using Java, Spring Boot, React, Kafka and Oracle. The team has built, and still maintains, platforms for some of the largest banks in Europe. Updated October 18, 2026 ### Who banking software development is for Banks and the consultancies and system integrators that deliver their projects: heads of digital channels, CTOs and delivery leads who need senior Java and React engineers used to banking security rules, to launch a new channel, extend a live platform or replace an outdated front end while the core keeps running. ### Typical use cases What DevsReady builds for a bank, from the banking platforms the team has built and maintains: - **Self-service corporate banking :** Payments, direct debit mandates and signed orders moved from branches, email and paper into a digital channel. [Case study](https://devsready.io/case-studies#next-generation-corporate-banking-platform) - **One platform for bankers :** Tasks, workflows and an activity log in the platform, instead of requests re-keyed between systems. [Case study](https://devsready.io/case-studies#next-generation-corporate-banking-platform) - **A live platform shared by a banking group :** New features for several banks across the CEE region, while the platform stays stable, secure and compliant. [Case study](https://devsready.io/case-studies#retail-banking-platform) - **Accessible web banking :** Interfaces refactored for screen readers, keyboard access and WCAG. [Case study](https://devsready.io/case-studies#accessibility-compliance-digital-banking) ### Banking problems we solve Banks rarely need software from a blank page. They need new capabilities on top of systems that already run the business. - **Operations outside digital channels :** Clients still use branches, email or paper for payments, direct debit mandates and orders that should be self-service. - **Back-office friction :** Bankers re-key requests between systems and track tasks outside the platform, with no single audit trail. - **Live platforms that must keep changing :** A platform shared by several banks in a group has to ship new features while staying stable, secure and compliant. - **Accessibility gaps :** Web banking that fails screen reader, keyboard and WCAG requirements. ### Typical digital banking architecture A digital banking platform works best in layers: channels for clients and bankers on top of Java and Spring Boot domain services, which reach the systems of record through APIs, messaging and events. Digital banking platform layers - Channels - Corporate internet banking - Retail web banking - Banker back office - Access and security - Authentication - Secure order signing - REST APIs - Domain services - Payments and transactions - Direct debit - Virtual branch forms - Tasks and workflows - Events and audit - Kafka - ActiveMQ - Activity log - Elasticsearch and Logstash - Systems of record - Core banking system - Oracle Database - Oracle Golden Gate A typical layered architecture, built from the stack used on DevsReady banking projects. Your own core system and platform are mapped during discovery. Separate layers let each channel release on its own cycle, keep business rules in one place and make every operation traceable: a signed order or a changed mandate leaves an entry in the activity log. ### What we deliver for banks - **Corporate banking modules :** Client and banker modules for payments and transactions, direct debit agreements and requests, a virtual branch with forms the bank creates itself, order signing, task management and activity logs. - **Retail banking evolution :** New features and fixes on a live retail platform shared by a banking group's banks across the CEE region. - **Wealth management tools :** Video meetings and secure document sharing between clients and advisors. - **Accessible interfaces :** WCAG-compliant components with screen reader and keyboard support. ### How we de-risk a banking project - **Discovery :** A conversation with the engineers about goals, systems and constraints, before any commitment. - **Proof of concept :** Free when you continue with DevsReady, from signed contract to working prototype in about one month. - **Governance :** A master services agreement with statements of work, and a direct line to the architect who leads the work. - **Security :** An NDA before you share details, and work inside the security rules, environments and processes your bank sets. - **Quality :** Engineers own their code from design to production monitoring, and no untested code goes to production. ### Banking technology stack Java, Spring and Spring Boot for services; React and Angular for interfaces; Kafka, ActiveMQ and REST APIs for integration; Elasticsearch and Logstash for logs; Oracle Database and Oracle Golden Gate for data; OpenShift and Docker for deployment. ### Proof and results Four case studies are banking work, with client names kept confidential: corporate clients of a large European bank run payments, direct debit and signed orders digitally, and a banking group's retail platform keeps gaining features across several countries. Figures are published only with client approval. A verified Clutch review covers a digital banking platform built for a technology consultancy.

DevsReady built a corporate internet banking platform and a secure remote advisory platform for major European banks, maintains a retail banking platform used across the CEE region, and made a large European bank's web applications accessible. #### How does DevsReady connect digital channels to our core banking system? Through the interfaces your core system already exposes, such as REST APIs, message queues, event streams or database replication, so the core keeps running unchanged. The approach for your system is agreed during discovery. #### Can DevsReady work on a banking platform that is already live? Yes. DevsReady provides evolutive maintenance for the live retail banking platform of one of the largest banks in Europe, shipping new features while keeping it stable, secure and compliant. #### Can DevsReady work through our system integrator or consultancy? Yes. DevsReady works with banks directly and with the consultancies and integrators that deliver bank projects. Its verified Clutch review comes from a digital banking project for a technology consultancy. ### Questions buyers ask Direct answers on how an engagement starts, what drives the cost, contracts and support. Prices are quoted per project after a discovery call. #### How does a banking engagement with DevsReady start? With a discovery call with the architect who would lead the work, under an NDA if you need one. A free proof of concept then goes from signed contract to working prototype in about one month, before the full project is planned. #### Can DevsReady work inside our bank's security processes? Yes. DevsReady works within the security rules, environments and processes the bank sets, and the specific controls are reviewed in your vendor assessment. DORA and PSD2 obligations stay with the bank, and DevsReady works under the GDPR as an EU-based company. #### Which time zone and language does the team work in? English, on Eastern European Time: one hour ahead of Central European Time and two ahead of the UK, so most of a European working day is shared. Romania is an EU member state, so DevsReady and its EU clients share one legal framework.
