Legacy systems blocking your growth? Modernize without disrupting operations.
We start with the one process that hurts most. You see results within a few weeks, without stopping your business.
Recognize these problems?
Most companies in your industry struggle with the same challenges. We know how to solve them.
Legacy systems impossible to maintain
Old systems based on outdated frameworks block new features. Every change takes months. Missing documentation and developer turnover make it worse.
Legacy maintenance costs grow 15-20% per year
Manual document processes
Loan applications, mortgage documents, regulatory reports, flowing through email and paper signatures. Error risk, no audit trail, frustrated customers.
Application processing takes days instead of hours
Systems don't talk to each other
Customer data is in three different databases. KNF reports require manual data assembly. Ad-hoc integrations generate technical debt.
Core banking, CRM, and reporting are three separate worlds
A solution in two steps
You don't have to roll out the whole system at once. Start with a quick win and grow at your own pace.
Step 1: Quick Win
Automation of one key document process, results visible in 3-4 weeks.
- Digital document workflow with OCR
- Automatic application routing to the right departments
- Audit trail and change history
- Integration with existing core banking
Step 2: Full Transformation
Architecture modernization or new system build, without service interruption.
- Legacy to microservices migration (Strangler Fig)
- ECM platform for document management
- Regulatory reporting (KNF, BFG, EBA)
- System integrations (Kafka, MassTransit)
- OpenTelemetry, full system observability
- Penetration testing and security audit
Banking-grade standards. In your company.
I designed and implemented systems for PKO Bank Polski, BFG, and PWPW. I know the security and reliability standards required in the financial sector, and I apply them to every project.
Frequently asked questions
Do you have experience with banking systems?
Yes, direct experience. I designed and implemented systems for PKO Bank Polski (ECM microservices platform with Kafka and OpenTelemetry), BFG (regulatory analytical platform), and PWPW (secure document production tracking). These aren't CV references, I was hands-on in every one of them.
How do you ensure security in financial systems?
We apply standards from banking projects: at-rest and in-transit encryption (TLS 1.3), OAuth 2.0/OIDC, RBAC, full audit log, Outbox Pattern for data consistency. Penetration tests before every production deployment.
Can you modernize an existing system without downtime?
Yes, that's our specialization. We use the Strangler Fig Pattern: gradually replacing old modules with new microservices, keeping the system running throughout. Production is never shut down.
