We are thrilled: together with our friends of mBank, we celebrated the full decommissioning of their Mainframe, rehosting their entire core banking system to .NET. And which better place for this celebration, than the wonderful Embassy of Belgium in Warsaw, where we enjoyed the warm and unconventional welcome of Mr Ambassador Rik Van Droogenbroeck? P.S.: Yes, you read it right. This is not about picking a low-hanging workload and moving it off the mainframe. It is about the entire mainframe being switched off. #Mainframe #DigitalTransformation #CoreBanking #LegacyModernization #DotNet #SoftwareEngineering #mBank #Fintech #EnterpriseIT #Microsoft #Raincode #Innovation #FutureOfBanking #Transformation #Milestone

Niezwykłe spotkanie w Ambasadzie Królestwa Belgii w Warszawie! 🇧🇪✨ 10 marca 2026 r. świętowaliśmy zakończenie projektu replatformingu systemu centralnego mBank S.A. — przejście z IBM mainframe na nowoczesne platformy #x86 oraz chmurę hybrydową. 🚀💻 Darius Blasband, CEO, Raincode, gospodarz wydarzenia, podkreślił, że w projektach technologicznych najważniejsi są ludzie. Fakt, że zostałem zaproszony, mimo iż od lat nie pracuję już w Microsoft, jest tego najlepszym dowodem. Dziękuję za to wyróżnienie! 🙏 Spotkanie uruchomiło lawinę wspomnień i refleksji: • mBank to historia polskiej innowacji i digitalizacji sektora bankowego • to także ważny etap mojej kariery na rynku IT — początek to projekt BRE 7, ja pracuję w IBM; klient wybiera system centralny Accenture a ja rozpoczynam współpracę od instalacji IBM Mainframe. • potem rynkowy debiut mBanku, lata nauki współpracy z klientem i dostawcą systemu, walka ekipy mBank o pierwsze „czarne zero”, moje uczestnictwo w #mRada - budowanie marki w erze dot.xn--comw-sqa - pozyskiwanie nie klientów a funów, budowanie społeczności • duma, gdy mBank był stawiany na świecie jako przykład najbardziej innowacyjnego projektu fintech 🌍🔥 • a potem zmiany, nowe zespoły, nowi liderzy i wyzwania: trudno zdobyć rynek, ale jeszcze trudniej go utrzymać i skalować biznes • potrzeba optymalizacji biznesu - ludzie się zmienili ale duch innowacji pozostał; dzięki niemu pojawił się pomysł replatformingu; a ja już w Microsoft - zatem ponowna współpraca z mBankiem! • moment przełomowy: Raincode — wyjątkowa belgijska firma, której technologia pozwoliła projekt zrealizować 💡🇧🇪 • po 12 latach determinacji, wysiłków i pracy… ZROBILI TO! 🎉 Największy projekt tego typu na świecie — brawo mBank S.A., brawo Raincode, brawo Accenture, brawo Microsoft! 👏👏 Zamiast długiej listy nazwisk (nie sposób kogoś nie ominąć) — podziękowania dla tych, których złapałem na zdjęciach: Michal Niedzwiecki, Darius Blasband, Krzysztof Dąbrowski, Michal Plechawski. I Paweł Kopacz — zabawne, że choć obaj już poza Microsoftem, to właśnie my „reprezentowaliśmy” technologię kluczową dla tego projektu 😉💙 "Bo w projektach technologicznych najważniejsi są ludzie." To był wieczór pełen refleksji i inspiracji. Dzięki! 🙌✨ #replatforming #digitaltransformation #optimization #hybridcloud #innovation

Mainframe modernization is increasingly appearing on every C‑level agenda—driven by cost savings, skill shortages, and the need to accelerate time to market. With the rise of AI, it can sometimes feel as though it is positioned as the answer to everything. AI is powerful and will undoubtedly help modernize our mainframes, but it is not the only answer. This evening, I was invited for a celebration party at the Belgium Embassy in Warsaw marking the successful completion of a full mainframe migration at mBank. For me, it was a meaningful milestone: I helped sell the original solution during my time at Accenture, and later, at Microsoft, supported both the customer and partner throughout the journey. Seeing the customer fully switch off their mainframe was incredibly rewarding. A big congratulation to mBank S.A. in Poland with Raincode as their mainframe modernization solution, to move their core banking solutions off the mainframe. We all know that mainframe environments using many languages, databases, and tools—there is no single solution that fits every scenario, not even AI. Tonight’s go‑live celebration proved that success comes from choosing the right approach for the customer’s specific challenge. The customer described the experience as feeling like a marriage, and the tool selected, in this case Raincode, was truly fit for purpose. This is what keeps me motivated after more than 20 years in this field. Every situation is different, every challenge is unique, and the work is never boring. Mainframe Modernization Rocks.

The end goal of mainframe migration is not simply moving to Azure. It is about building a truly cloud-native fabric of containers and microservices that can continuously evolve, scale, and adapt over time. Raincode delivers cloud-native mainframe modernization. #Raincode #MainframeModernization #CloudNative #CloudTransformation #LegacyModernization
