Summary
Oleg Stadnichenko is a Staff Engineer based in London with over a decade of experience building resilient, cost-efficient systems for fintech and banking. He specializes in Java, microservice architecture, and database design, and has repeatedly driven fee reductions and reliability improvements by replacing third-party processors and developing in-house cryptography and processing integrations. Oleg has a strong track record of splitting monoliths into observable microservices, integrating legacy data platforms like Hadoop, and leading migrations that decommission expensive legacy systems. As a hands-on technical leader he mentors teams, implements observability and alerting, and partners with cross-functional stakeholders to align engineering with business outcomes. He is an active public speaker who shares knowledge within the community and brings a blend of rigorous applied-maths training from MIPT and practical production experience. Notably, his integrations with major processors (including Visa) have unlocked new client opportunities while materially reducing operational costs.
