ABOUT NICK ZYLKOWSKI
Senior engineering leader with 10+ years driving technology strategy, building platform infrastructure, scalable systems, and high-performing teams across high-growth European B2B SaaS, Fintech, and e-commerce companies.Currently leading backend engineering at Qonto across two domains (groups of teams), where I\'ve grown from a payments system platform to owning the entire core banking infrastructure - managing 45+ engineers across 7 distributed teams. Delivered platform engineering at scale: in-house card processor achieving 7-figure cost savings, new acquiring product lines (payment links, tap-to-pay) reaching >100% MoM growth, and GenAI-powered operational tools via API-first microservices architecture, cloud infrastructure (AWS), and cross-functional leadership and stakeholder management.Previously at Westwing, I grew from Senior Engineer to Director over 7 years, ultimately leading 45 engineers across 3 remote/hybrid tribes (teams of teams). Key achievements include building ML-powered product recommendations that generated €4M annual revenue, building a data platform processing 2B+ monthly events with GDPR compliance, and architecting cloud-native scalable systems achieving 99.9% uptime during 5x traffic events, while maintaining 90%+ engagement during major organisational transformations through transparent communication and strategic planning.My leadership approach focuses on delivering business outcomes through technical excellence. I help organisations achieve measurable results - cost reduction, revenue growth, operational resilience - by building engineering teams that understand both the technical \"how\" of platform engineering, API design, and cloud architecture, and the business \"why\" behind their work. This means connecting daily engineering decisions to company strategy, fostering ownership across distributed teams, and maintaining a sustainable delivery pace without sacrificing quality.I develop technical leaders who combine deep expertise in scalable systems and modern infrastructure with strong cross-functional collaboration skills - creating organisations where engineering drives competitive advantage, not just executes requirements.
