# i'm sladyn > [!right-card] > ![[Assets/sreguy-mark.svg]] I am a production engineer who likes understanding how systems actually work. This site is where I write about Linux, production engineering, distributed systems, open source, AI infrastructure, incidents, debugging, and the craft of becoming a stronger engineer. Some pages are polished essays. Some are shorter field notes that will keep evolving. The goal is not to make a perfect blog feed. The goal is to build a useful technical field manual over time. --- ### start exploring [[Topics/Production Engineering|Production Engineering]] is the best entry point if you care about reliability, incidents, debugging, runbooks, SLOs, and operating real systems. [[Topics/Linux & Systems|Linux & Systems]] is where I collect notes on syscalls, file descriptors, kernel boundaries, I/O, and operating system fundamentals. [[Topics/AI Infrastructure|AI Infrastructure]] is where I write about inference engines, prefill, decode, KV cache, GPUs, and the systems side of modern AI. --- ### featured writing - [[Articles/Tracing System Calls at a High Level]] - [[Articles/File Descriptors Part 1]] - [[Articles/File Descriptors Part 2]] - [[Articles/Inference Core Loop of an Inference Engine]] - [[Articles/Inference Prefill and Decode]] --- ### field notes - [[Field Notes/Backpressure]] - [[Field Notes/File Descriptor]] - [[Field Notes/Tail Latency]] - [[Field Notes/KV Cache]] - [[Field Notes/SLO]] - [[Field Notes/Runbook]] <nav class="net-links" aria-label="Find me on the net"> <a href="https://github.com/sladyn98" title="github" aria-label="github"><span>GH</span></a> <a href="https://www.linkedin.com/in/sladyn-nunes" title="linkedin" aria-label="linkedin"><span>IN</span></a> <a href="https://x.com/SladynN" title="x/twitter" aria-label="x/twitter"><span>X</span></a> <a href="https://www.youtube.com/@theSREGuy" title="youtube" aria-label="youtube"><span>YT</span></a> </nav>
