Decoding the mechanics of high-performance systems.
Reviewing the technical evolution of this blog over a decade: from managed platforms and dynamic backends to a custom, zero-dependency Hugo architecture.
A pragmatic guide to running k3s inside WSL2 on a Windows gaming PC and accessing it securely from a MacBook. No LAN exposure, no fragile port proxies: just SSH and control-plane tunneling.
Ingesting PII is easy; cleaning it up is hard. Here is how to use ClickHouse's data masking policies and regex to redact sensitive logs in flight without killing your query performance.
A practical guide to understanding how CPU caches (L1/L2/L3) impact Go service performance, with benchmarks on modern hardware.
Postgres is the swiss-army knife of databases, but when you hit the 10-million row mark for write-heavy logs, the relational wall becomes real. Here is why we moved our observability stack to ClickHouse.
If you're building Go applications on WSL2 and keeping your source code on the Windows filesystem, you're paying a hidden performance tax on every build. Here is how to reclaim your CPU cycles.
Two years of coding with AI every day: what actually saves time, what creates hidden debt, and why your fundamentals are your only real defense against hallucinated correctness.
Waiting 2 minutes to see a typo fix? Runtime containers separate your code from your runtime, enabling instant feedback without sacrificing containerized consistency. Mount your code instead of baking it in. Edit files, see changes instantly. No rebuilds, no waiting.
Your background jobs crash on deployment, fail silently, and corrupt data. Here's how to fix it with worker pools, retry strategies, idempotency, and graceful shutdown. A guide to building production background processing systems that don't break under load. Tested at 20 req/sec.
Your Go structs might be wasting up to 32% of their memory due to invisible padding bytes. This deep dive into struct field alignment reveals how the compiler arranges memory, why field order matters, and provides benchmarks showing real memory savings. Learn the simple reordering rules that can shrink your heap, reduce GC pressure, and improve CPU cache efficiency.
Senior software engineer working mostly in Go. I build backend systems and AI applications: feeds, search, LLMs, the infrastructure underneath. When something doesn't make sense, I pull it apart until it does. This blog is where I write that up.
