Available to hire
I’m Alexey G. Gerasimov, a Senior Technical Architect focused on turning complexity into clarity for enterprise integration and system modernization. I help customers design, implement, and migrate robust solutions, including Oracle Cloud-based options, to create stable, scalable platforms. I follow a ‘Go Beyond’ approach to not only fix current issues but also deliver improvements that prevent future problems.
Over the years I’ve led and advised teams across large organizations, including Sofigate Oy, Oracle, SAP, Deutsche Telekom, and the Pulkovo Observatory, working across finance, telecom, public sector, and research contexts. I excel at bridging product management, development, and operations to deliver enterprise-grade integration, data pipelines, and cloud modernization initiatives.
