In software development, we often celebrate elegant code or clever architectures—but these mean nothing if they solve the wrong problem. The pressure to deliver quickly tempts us to skip fundamental steps, yet the best solutions emerge from disciplined problem-solving first. This isn’t about methodology dogma; it’s about recognizing that code is just one tool in a larger process. Let’s explore how focusing on the problem space—through requirements, modular design, and continuous collaboration—creates software that actually delivers value.

Software architecture decisions often come down to invisible tradeoffs. While microservices have dominated recent conversations as the 'modern' solution, their benefits frequently come with hidden complexities that aren’t immediately apparent. Through this exploration, I want to unpack both sides of this architectural debate—not to prescribe one approach over another, but to highlight the considerations that truly matter when choosing between distributed and monolithic designs. The best solutions emerge not from following trends, but from understanding these fundamental tensions.

When designing systems, the choice between multi-tenancy and single-tenancy can significantly impact complexity and scalability. Imagine building a solution for just one customer—how much simpler would it be? While multi-tenancy demands handling multiple customers seamlessly, single-tenancy can offer straightforward, scalable solutions when requirements are carefully examined. In this article, I’ll share a real-world example where a simple proxy service, rather than a complex multi-tenant overhaul, effectively solved the problem of data compartmentalization. The key takeaway? Always evaluate your specific needs and opt for simplicity and expandability over unnecessary complexity.

Kubernetes has become synonymous with modern infrastructure, but is it always the right tool for the job? While its scalability and automation are appealing, they can lead to a lack of critical thinking about core metrics like user behavior, response times, and redundancy. As a fan of straightforward solutions—like Go for programming—I believe infrastructure should be simple, predictable, and easy to understand. In this article, I’ll share why I’ve often opted for simpler setups using tools like Traefik, NATS, and Ansible, which have proven to be highly scalable and maintainable without the overhead of Kubernetes. Sometimes, boring infrastructure is a sign that everything has been done right.

Testing during development is essential, but real-world scenarios often defy expectations. To ensure my code performs reliably in production, I’ve adopted a strategy I first used almost a decade ago: writing the same logic twice. Ideally, two developers independently implement the logic, sometimes even in different programming languages. Only when both versions produce identical results in production is the code accepted. While this approach isn’t practical for every function, it’s invaluable for critical systems. Whether running both implementations continuously or temporarily after updates, this method complements traditional testing. In this article, I’ll discuss how double programming can enhance fault tolerance, error detection, and safety in production environments.

In the world of web-based and network service projects, debates about programming languages often take center stage. But when it comes to operational costs, the language you choose is usually just a small piece of the puzzle. From Kubernetes clusters and load balancers to databases and storage solutions, infrastructure and architecture play a far more significant role in determining your expenses. A poorly designed system can drain your budget, regardless of whether you’re using Java, Python, Go, or Rust. In this article, I’ll explain why effective cost reduction starts with optimizing your infrastructure and architecture—not with chasing the ‘right’ programming language.
