My Services

What: I provide a proven, end-to-end framework for digital transformation, built on my battle-tested experience transitioning an outdated IT team into a best-in-class Platform Engineering team. I help you establish a clear team identity, prove business value with metrics like DORA, and redesign your organization for scalability using principles like the Reverse Conway Maneuver.

Why: Many organisations struggle to transition their legacy IT systems and teams to a truly effective Cloud-Native model. This creates bottlenecks, hinders innovation, and prevents them from realising a return on their technology investments. I bridge the gap between technical theory and enterprise reality to help you build a high-performing team that accelerates innovation, reduces costs, and is prepared for long-term success.

Whom: This service is for mid-to-large organisations that need to modernise their technology and culture. It is specifically for CIOs, CTOs, VPs of Engineering, and business leaders who are committed to a fundamental digital transformation and want to turn their technology department into a core driver of business growth.

Why: Cloud-Native and Platform Engineering teams often struggle to prove their value beyond technical metrics, making it difficult to secure budgets and strategic alignment.

What: I provide a proven framework and advisory service to help you measure and manage the business success of your platform, using clear, quantifiable KPIs.

Whom: Startups, scale-ups, and mid-to-large organizations that are serious about their operations and need to demonstrate the ROI of their platform investments.

Why: To truly succeed in Cloud Native, you must move beyond technology and build a high-efficiency team. Most companies struggle with the right organizational design, leading to lost productivity.

What: I provide a proven methodology for designing and implementing optimal team topologies to accelerate flow and empower your engineers.

Who: Ideal for startups and scale-ups building their first platforms, as well as mid-to-large organizations planning or executing their digital transformations.

Why: Digital Operational Resilience Act (DORA) elevates Site Reliability Engineering (SRE) from a technical discipline to a strategic and regulatory-critical function. DORA mandates and formalises many practices that are central to SRE, forcing companies to adopt a more rigorous and auditable approach to reliability

What: HandsOn Advisory on (re)thinking the SRE as a business-driven process aligned with the new DORA regulations

Whom: Startups(building the future of SRE and Incident management), Any organisations impacted by regulations or building their IncMgmt process

Why: Digital Operational Resilience Act (DORA) is reshaping the way Operations look like in Finacial Sector. Operations need to meet the stringent demands of operational resilience. Incident Management seat at the forefront of this silent revolution.

What: HandsOn Advisory on building business-driven incident management fully aligned with latest European Regulations.

Whom: Startups(building the future of SRE and Incident management), Mid-large organisations (concerned about operations)

But his impact doesn’t stop there. Beyond his technical expertise, Sergiu is a true industry and thought leader. Whether he's leading discussions on cloud-native best practices, analyzing the intersection of AI and digital transformation, or mentoring the next generation of engineers, he consistently combines strategic foresight with hands-on expertise. He's a brilliant guy, and I enjoy talking to him whenever I can!"

“I am glad I met Sergiu years ago as part of my network. He truly is a great leader and thought leader with strong core values. Next to his forward-looking and visionary views on modern ways of engineering, he is very collaborative, highly responsive and passionate about his work. Acting as a speaker he loves to share his knowledge and brings people together. You can always feel his passion and take something new and inspiring out of it. He is one of the people you want to have in your network and always enjoy talking to"

"Sergiu brings a rare combination of deep technical expertise and strong leadership. His work leading cloud infrastructure and platform engineering at Allianz has been nothing short of transformative—he's built teams that don't just keep up with the pace of change in tech, they help define it. Whether you're talking cloud-native strategy, platform architecture, or scaling engineering culture, Sergiu brings clarity, direction, and an ability to execute at the highest level. He's the kind of person you want in the room when you're solving complex problems or mapping out ambitious goals."

"I’ve had the privilege of connecting with Sergiu through Kubecon CNCF events where his passion for the cloud-native community shines through every interaction.
