Engineering capabilities
Whitestein delivers software across the full lifecycle — from greenfield product development to legacy modernization
Senior engineering teams. Long-term partnerships.
50 senior engineers, architects, and QA based in Bratislava deliver as dedicated teams — embedded with our clients' product owners and architecture leads, working in the same time zone.
Our average client relationship runs 10–20 years. Stable teams retain product knowledge across major initiatives and regulatory cycles, reducing risk and accelerating each new programme.
Capabilities across the software lifecycle
AI integration
LLM and ML capabilities embedded into core processes — fraud detection, document understanding, advisor support.
Product engineering
New systems built end-to-end — architecture, backend, frontend, QA, DevOps, and ongoing operation.
Legacy modernization
Migrate mainframe and monolithic platforms to modern, cloud-native architectures without disrupting operations.
System integration
Connect core banking, policy, and claims systems with modern channels, APIs, and partner ecosystems.
Cloud-native architecture
AWS, Azure, GCP. Containerized, observable, automatable. Built for elastic scale and operational stability.
Compliance & security
GDPR, DORA, Solvency II, MiFID II — built into delivery practices, not bolted on at the end.
Technology stack
Our engineers work fluently across the platforms European banks and insurers run today — and the cloud-native stacks they are migrating to.
