Iaşi, Romania


Driven by a zest for technology and fun in equal measure, I've navigated from hands-on coding across full-stack and frontend to steering technical leadership and architecture. Embracing change, I've evolved, always eager to push beyond the familiar. My experience spans a rich variety of domains, including remote device management and monitoring, payroll, healthcare, media, e-commerce, and software for municipalities, in both insourcing and outsourcing models.
Alongside my technical contributions, I've enriched my career by mentoring emerging talent and engaging audiences at conferences, sharing insights and fostering a community of learning and innovation.

Beyond the realm of coding, I am passionate about sharing insights, whether through thought-provoking articles or by distilling my experience into my book, "Software Architecture for Web Developers."

You'll be immersed in practical examples and case studies showcasing how AI tools like GitHub Copilot, TabNine, and Kite have transformed software development. Walk away with actionable insights, real-world success stories, and a clear understanding of how AI can redefine your development processes.

Quit learning frameworks like there is no tomorrow

In a period when technology changes like fashion, time is the most precious resource we have and, trying to learn all the new frameworks mostly becomes a waste of it. Although at first sight, they might seem different, we have to pay attention to the same specific important elements. The real challenge is to stay relevant by investing in the knowledge that survives the test of time. Key characteristics like resilience, accessibility, staleness, or latency are easily overlooked when building applications, but they do make a difference when applied.


Picture yourself working with an app that has a web and a mobile version, or better yet, just several different types of clients that consume the same APIs but are being built by totally different teams. The functionalities they provide are distinct, hence the need for distinct sets of data and functionalities. You might think that the solution for this is having an “as generic as possible” backend for all UI’s. From my experience, this kind of backend leads to huge issues in matters of performance, entangled user experience as well as extra and unnecessary communication for the development teams to align and meet their needs. Fortunately, there is a promising set of approaches taking the stage as they are created to optimize how front-end applications collaborate with backends: BFF (Backend-For-Frontend) pattern and GraphQL. Given these two approaches, which one is the right to consider? Join me in a talk where we will discuss the two approaches, underline both their good and bad sides, and determine which you should consider as the most appropriate for your frontend application and business context.

From REST to GraphQL

Sometimes, RESTful APIs limit us regarding how we need to shape data. Although REST is a proven and valid choice when transporting data, details like versioning, managing multiple endpoints, over fetching, under fetching, or chattiness when trying to fully satisfy the needs of an application make us waste a lot of time and ignore some essential metrics. In this session, we will discuss GraphQL, its benefits, how to approach the decision to use it, and how to consume GraphQL in various scenarios, including in combination with REST.


Too often, we encounter the idea that software architecture is an esoteric concept, which only the chosen ones are allowed to discuss at the right time. Well, how about a bit of a change of perspective? With software development and users' needs evolving so fast, we don’t afford the luxury of rewriting systems from scratch just because teams fail to understand what they are building. Today’s software developers are tomorrow's architects. We must challenge them to step away from the IDE and understand how the architecture evolves to create a common and stable ground regarding quality, performance, reliability, and scalability. At the same time, software architects must step away from abstractions and stay updated on the project development reality. This session revolves around finding the right ways of intertwining up-front architecture, API design & coding while maintaining a continuous focus on architecture evolution.

The discussion about reactive systems we all need

More than ever business applications feel the need of embracing responsiveness at its finest, be flexible, scalable, and guarantee resilience. As a result, there is an increasing tendency in adopting reactive approaches which even though seem complex in the beginning, strike as necessary for the development process of the application in the long run. What are the core concepts of the reactive paradigm? How do I decide if it's the right tool for the job? What are the challenges when applied in real-life projects? These will be some of the questions we will answer in order to provide a good understanding of what reactive programming stands for, what reactive systems bring to the table, how to apply design principles in various projects, and how to create fully reactive architectures.

How to Fail Big at Being a Tech Lead

Although leadership skills have been analyzed for so long, there is something in the way we choose and raise our technical leads that defy all laws. We often think that the brightest and most creative person in the team will eventually become a technical lead, which actually happens in most cases. The exciting part, though, the process of becoming a technical lead starts when we actually take over the role. What seemed to be a gratification for excellent results can become a long list of failures if you don’t really, really prepare for the challenge. Luckily we can learn from each other’s mistakes, so join us to touch some hot spots in the technical leadership journey.

Architecting frontend

Building frontend architectures open to change and performant can get very complicated. But we don't talk about it. We either get stuck in debates about which framework is best or rely blindly on the approach proposed by the next "solve-all-your-problems-fit-all-scenarios" technology. Very few discussions are about architectural patterns and issues in the frontend area.

Although it is an essential step in the right direction, frontend architecture is not only about building reusable components. Nowadays, we do much of the heavy lifting on the frontend side. Therefore we need resilient structures that quickly adapt to the market's ever-changing needs.

In this session, we will discuss ways that will help us avoid getting lost in the complexity of frontend applications. We will discuss different patterns and ways to approach frontend architecture when starting a new project and when trying to save an existing one.

Modern App Development: Adopting, developing and operating well-architected workloads

The Azure Well-Architected Framework and Azure Cloud Adoption Framework provide a comprehensive approach to designing, operating, and optimizing cloud-based systems on Azure. The Azure Well-Architected Framework is a set of best practices that helps organizations design and operate their cloud-based systems in a secure, reliable, and scalable manner. The Azure Cloud Adoption Framework is a set of guidelines and best practices for planning and executing a successful cloud adoption strategy. In this session, we will this discuss how these frameworks help organizations ensure their cloud solutions are reliable, scalable, and secure while maximizing cost-effectiveness and operational efficiency.
