Title: The Year End Reflection: LLMs Are Everywhere, But Dev Experience Matters

---

December 30, 2024. Another year in the tech world has rolled by, and it feels like we’re living in a perpetual beta. Let’s take a moment to reflect on what’s been going on.

The AI Surge

This year was dominated by large language models (LLMs) and their infrastructural requirements. ChatGPT may have been the spark that lit the fire, but its aftermath has been a whirlwind of innovation and scaling challenges. Our team at Platform Engineering had to grapple with managing LLM infrastructure at scale—balancing performance, cost, and security. One big project was optimizing our LLM clusters using Kubernetes for better resource utilization. It wasn’t always smooth sailing; there were plenty of nights spent troubleshooting node failures and scaling issues.

WebAssembly’s Growth

WebAssembly (Wasm) continued its march onto the server side. We experimented with Wasm to offload some of our compute-heavy tasks, like image processing and encryption. The promise was there—write once, run everywhere. But in practice, it wasn’t as straightforward. Compatibility issues and performance bottlenecks meant that we often had to fall back on traditional languages and frameworks.

Developer Experience

DevOps has become a mainstream discipline. At our company, the DevEx team took center stage, pushing for better developer tooling and workflows. We launched a CI/CD platform that integrated seamlessly with our existing infrastructure. The feedback from developers was mixed—some loved the speed and efficiency, while others felt it lacked flexibility.

FinOps and Cloud Costs

FinOps continued to be a hot topic. With cloud providers offering a dizzying array of services, budgeting and cost management became even more complex. We implemented a tool that automatically tracked our spending across multiple accounts and regions. It was like trying to herd cats—constantly adjusting budgets and optimizing resource allocation.

DORA Metrics

DORA (DevOps Research & Assessment) metrics remained widely adopted as we focused on reducing lead times, mean time to recovery, and failure rates. Our team worked hard to streamline our release processes, aiming for faster feedback loops and quicker iterations. However, the struggle was real—balancing speed with quality never gets any easier.

Personal Reflections

On a personal level, I found myself spending more time thinking about the human aspect of tech. Too often, we focus on the technology itself without considering its impact on developers and end-users. The Cognitive Load article resonated deeply; it’s not just about pushing more features or faster performance; it’s about creating systems that are intuitive and enjoyable to use.

Looking Ahead

As we wrap up 2024, I’m excited yet weary. The landscape is shifting rapidly, with new tools and frameworks emerging every day. My hope is that as technology evolves, so too does the focus on developer experience—making sure that the tools and platforms we build enhance our work rather than become an obstacle.

Here’s to 2025 and a renewed commitment to excellence in both tech and people!

This year, like many before it, was filled with challenges but also opportunities for growth. The next chapter is just beginning, and I’m eager to see what it holds.
