    Go Concurrency Patterns I Use in Every Service Worker pools, fan-out/fan-in, pipelines, and the cancellation discipline that keeps Go services predictable under load. go architecture backend Caching: The Easy Part Is Adding It, the Hard Part Is Everything Else Cache-aside, write-through, invalidation strategies, and the failure modes that will wake you up at night. With Go examples. performance databases go Rate Limiting: The Boring Feature That Saves You at 3 AM Rate limiting algorithms, implementation tradeoffs, and practical lessons from building limiters for high-traffic APIs at a real-time messaging company. api backend go PostgreSQL Performance: Measure First, Tune Second Most Postgres performance problems are indexing problems. The rest are vacuum problems. Here's how to find and fix both. databases performance backend API Versioning: Pick One and Stop Overthinking It API versioning is a maintenance commitment, not a design exercise. URL paths for public APIs, headers for internal. The real work is avoiding breaking changes. api architecture backend Message Queues: The Patterns Nobody Tells You About Until 3 AM Queues look simple on a whiteboard. Then you deploy them. The messaging patterns I've learned the hard way across three startups, with real failure stories. architecture go backend The PostgreSQL Tuning Playbook I Actually Use Battle-tested PostgreSQL tuning: connection pooling, memory sizing, index discipline, vacuum management, and the queries that tell you what's broken. databases performance backend Your API Is a Contract You Can't Take Back Hard-won lessons on designing HTTP APIs that survive real integrations, drawn from building fintech and mobility platforms. api engineering backend Async Job Processing: Patterns That Saved Us at a Fintech Startup Hard-won patterns for reliable background job processing -- queues, retries, idempotency, and the failures that taught me to care about all three. backend architecture reliability API Rate Limiting: What Actually Works Algorithms, headers, and deployment patterns for rate limiting APIs -- drawn from building financial data services at the fintech startup. api backend architecture Making Go Services Fast: What Actually Matters Practical patterns for squeezing performance out of Go services — profiling, allocation control, bounded concurrency, and HTTP/DB tuning from real production work. go performance backend GraphQL in Production Is Harder Than They Tell You After a year running GraphQL at the fintech startup, here's what the conference talks leave out. api backend production A Go Developer Looks at Rust for Backend Work I write Go every day at the fintech startup. Here's why I've been spending evenings with Rust, what impressed me, and where it still hurts. engineering go backend Machine Learning for Backend Engineers: What Actually Matters What backend engineers actually need to know about ML in production -- from someone who builds NLP pipelines for financial news. ai backend engineering Why We Chose Go for Our Backend Services How Go became the default backend language at a mobility startup and a fintech startup, what it replaced, and the honest tradeoffs we accepted along the way. go backend engineering
