Backend systems, architecture, AI workflows, and the small decisions that decide whether software stays calm under pressure.
Short enough to scan. Useful enough to come back to.
What happens when requests arrive faster than your system can process them? Learn how backpressure prevents growing queues, overloaded databases, retry storms, and system crashes.
Learn how the Transactional Outbox Pattern prevents lost events and inconsistent data when a service must update its database and publish a message at the same time.
Your development environment is where your code, secrets, tools, and AI workflows all meet. Here are practical, developer-friendly security habits to keep your local setup safe without killing your productivity.
A practical breakdown of what happens when a user opens a website hosted on AWS , from DNS resolution in Route 53 to CloudFront, load balancers, VPC networking, backend services, databases, APIs, and frontend rendering.
AI coding tools become far more powerful when we stop treating them like random chatbots and start structuring them like engineering collaborators. This article explores how Claude Code, CLAUDE.md, SKILL.md, custom skills, commands, MCP, hooks, and context engineering can turn AI-assisted development into a repeatable workflow for understanding, changing, reviewing, and shipping code.
How I’d evolve a simple EC2 + RDS MVC app into a system that can handle millions of users, layer by layer, without overengineering too early.
