Where the depth lives
Notes from building backend systems: what I designed, what broke, and the reasoning I wish I had written down the first time.
Topics
Four threads I keep pulling on
Not tutorials. Working notes: what I tried, what it cost, and what I would tell myself before starting.
AI
Agents, LLMs, RAG and AI architecture — what I build, test and break.
System Design
Distributed systems, databases, messaging, caching and scaling.
Code & Snippets
Working references from Java, Spring, PostgreSQL, Kafka, Redis and Kubernetes.
Architecture Lab
Full write-ups from problem to trade-offs, with the diagrams to match.
