How Much Does Big-O Matter in System Design?
Use asymptotic complexity to spot growth problems, then budget the I/O, fan-out, queues, and failures it cannot describe.
Engineering Field Notes
Capacity Estimation: From DAU to QPS, Storage, and Bandwidth
Turn user activity into traffic, data, and network budgets—then test the assumptions before buying capacity.
Engineering Field Notes
Stateless vs Stateful: Where Does the State Live?
Why moving state out of a server changes scaling and failure boundaries—and when keeping state close to computation is the better choice.
Engineering Field Notes
Vertical vs Horizontal Scaling: Where the Bottleneck Moves
A practical guide to adding capacity, finding the real bottleneck, and deciding when one larger node is simpler than many smaller ones.

What Scalability Really Means
How to reason about growth, bottlenecks, load distribution, partitioning, overload, and the cost of adding capacity.
