Engineering Insights
from the Trenches

Writing 1 as an integer costs 1 byte (8 bits), but as binary it needs just 1 bit — an 8× reduction. Exactly why gRPC with Protocol Buffers crushes REST+JSON at scale. #gRPC

Always use UUIDs as primary keys in SQL to eliminate sequential ID enumeration. One architectural decision that prevents entire classes of IDOR attacks. #Security

Leaderless Replication achieves strong consistency via quorum-based reads and writes. When R + W > N, you guarantee overlap — no stale data sneaks through. #DistributedSystems

Bloom Filters eliminate unnecessary DB calls, trading just 1.13 MB of memory for a 1% false positive rate across 1 million records. A go-to trick for cutting DB load at scale. #Performance

UUID collisions are practically impossible — generating 1 billion UUIDs per second for 100 years only brings the duplicate probability to 50%. Ship with confidence. #Reliability
