My journey from working on embedded systems to building data infrastructure has been a fascinating evolution that parallels the broader development of technology over the past decade. This transition wasn't planned, but rather emerged organically as I followed my curiosity and the changing technological landscape.

The Embedded Systems Era

I began my career working on embedded systems - designing and programming the small computers that control specific functions within larger mechanical or electrical systems. This work was concrete and tangible; I could hold the hardware in my hands, and the software I wrote had immediate physical effects in the world.

The constraints of embedded systems - limited processing power, memory, and energy - taught me to write efficient code and think carefully about resource utilization. These systems operated in isolation or in small networks, with relatively simple data flows.

The Transition Phase

As connected devices proliferated and the Internet of Things emerged, the embedded systems I worked on began generating more data. This data needed to be collected, stored, processed, and analyzed. Gradually, my focus shifted from the devices themselves to the infrastructure needed to handle their data.

This transition period involved learning about distributed systems, cloud computing, and data processing at scale - areas quite different from the microcontroller programming I was familiar with. Yet the fundamental principles of efficiency and reliability remained crucial.

The Data Infrastructure Present

Today, my work focuses on building infrastructure for real-time inference on streaming data. This involves designing systems that can ingest, process, and derive insights from massive data streams with minimal latency.

The scale and complexity of these systems are orders of magnitude greater than the embedded systems I started with, but I find that my background gives me a unique perspective. Understanding both the sources of data (the embedded devices) and the infrastructure that processes it allows me to design more effective end-to-end solutions.

Parallels to AI Development

This journey from embedded systems to data infrastructure mirrors the development of artificial intelligence in many ways. AI began with simple, rule-based systems operating in constrained environments, similar to embedded systems. It has evolved into complex, distributed systems that process vast amounts of data and learn from it - more akin to modern data infrastructure.

The future of AI will likely involve a convergence of these domains, with intelligent systems embedded throughout our physical world, connected to powerful data infrastructure that enables them to learn and adapt. My background in both areas positions me to contribute to this exciting frontier.

Lessons Learned

The most valuable lesson from this journey has been the importance of adaptability and continuous learning. Technology evolves rapidly, and the skills needed today may be different from those needed tomorrow. By following my curiosity and embracing new challenges, I've been able to stay relevant and contribute to cutting-edge projects.

I've also learned that seemingly disparate domains often have unexpected connections. The principles of efficiency and reliability that guided my work on embedded systems remain relevant in data infrastructure, albeit applied in different ways.

As I look to the future, I'm excited to continue exploring the intersection of physical and digital systems, and to contribute to the development of infrastructure that enables the next generation of intelligent applications.
