Distributed Tracing in Production Go Services on AWS ECS

Once you have more than two Go services talking to each other on ECS, a slow request becomes a needle in a haystack. This is how we wire distributed tracing with OpenTelemetry across services, propagate trace context through HTTP and gRPC, and ship spans to a collector sidecar without adding more than a few milliseconds of overhead.

Soft Deletes in Multi-Tenant PostgreSQL: Patterns and Pitfalls

Soft deletes look simple: add a deleted_at column, filter on NULL, done. In a multi-tenant PostgreSQL database at scale, the naive implementation creates index bloat, breaks your Row Level Security policies, and leaks deleted data in COUNT queries. This post covers the correct patterns and the specific PostgreSQL behaviors you need to know before shipping soft deletes to production.

Event Sourcing in Go: Building an Append-Only Event Store with PostgreSQL

Event sourcing stores the full history of what happened to your data, not just its current state. In the right context, it eliminates entire categories of audit and debugging problems. In the wrong context, it adds weeks of complexity for no gain. This post covers how to build a simple event store in PostgreSQL with Go, when the pattern is worth it, and the specific points where teams consistently overcomplicate it.

Optimizing Go Docker Images for AWS ECS: Multi-Stage Builds and Minimal Containers

A naive Go Docker image built from the official golang base weighs close to 900 MB. The same binary in a scratch container is under 10 MB. That gap matters in AWS ECS: smaller images push faster to ECR, pull faster onto Fargate tasks, and shrink your attack surface. Here is how we build Go containers for production.

Structuring a Go SaaS Backend: Package Design, Interfaces, and Dependency Injection That Scales

A Go SaaS backend that starts with a handful of files eventually becomes a codebase with dozens of packages and hundreds of files.

Service-to-Service Authentication in Go Microservices: Internal Tokens and Shared Secrets in Production

In a microservices backend, services call other services constantly. Order service calls billing service. Billing service calls notification service. These internal calls need authentication, but the mechanism you choose matters. Too simple and you have no security. Too complex and you have an operational nightmare. Here is how we handle it in production Go backends.

Building a Loyalty Points and Rewards System in Go for SaaS Platforms

Loyalty programs fail in production when the points ledger drifts, tier calculations are inconsistent, or redemption races cause balance errors.

Coordinating Distributed Transactions in Go: The Saga Pattern in Production

In a system where one operation requires writing to the main database, charging a payment processor, sending a notification, and updating a cache, you cannot wrap all of that in a single database transaction. The saga pattern is the standard solution, and orchestration-based sagas are significantly easier to debug in production than choreography-based ones.

Building Internal Workflow Automation for Operational Teams with Go

Customer-facing automation gets most of the engineering attention in SaaS products. Internal workflows, the ones that run inside the operations team, are where actual hours get consumed every day.
