The Strangler Fig Pattern: Incrementally Migrating Legacy Systems Without the Big Rewrite
Every engineering team eventually faces the same daunting question: what do we do with the legacy monolith? The temptation is

Event Sourcing in Practice: Building a System That Never Forgets
Most systems today use CRUD: read the current state, modify a row, write it back. The database remembers where things

The Saga Pattern: Coordinating Distributed Transactions in Microservices
Distributed transactions are one of those problems that look simple until you split your monolith into services. In a single

OpenTelemetry in Go: From Zero to Distributed Tracing
Microservices promised us smaller, more maintainable codebases. They delivered — along with a debugging nightmare. When a request flows through

CQRS in Practice: Splitting Reads and Writes for Scalable Systems
Most applications start with a simple mental model: one database, one set of tables, and CRUD operations that read and

Zero Trust Microservices: Implementing mTLS in Go
Most microservice architectures still rely on an outdated security model: trust everything inside the network, and defend the perimeter. The

Implementing Idempotency in Go: Keys, Stores, and Patterns for Reliable APIs
Networks are unreliable. Clients retry requests. Messages get delivered twice. In a distributed system, the question isn’t whether a duplicate

The Saga Pattern in Distributed Systems: Orchestrating Transactions Across Microservices
Every developer who has worked with microservices eventually hits the same wall: a single business operation needs to touch multiple
The Circuit Breaker Pattern in Go: Preventing Cascading Failures in Distributed Systems
When one service in a distributed system starts failing, the cascade can bring down everything downstream. A slow database connection
