How I Built Promptly: Solving AI Prompt Management at Scale

The moment I realized we had a problem was when our QA engineer asked, 'How do we know if someone accidentally changed how the AI behaves?' We had prompts scattered across a dozen files, each slightly different, with no way to test or version them. It hit me: we were making the same mistakes Rails solved 15 years ago with hardcoded strings. AI prompts aren't just text, they're critical business logic that shapes user experience. So I built Promptly to bring Rails conventions to AI development, treating prompts like the first-class citizens they should be. The result? 60% faster AI feature development and actual regression testing for AI behavior. Sometimes the best solutions aren't about new technology; they're about applying proven patterns to new problems.

Caching with intent: How to avoid the Redis graveyard

Effective caching strategies require intentional design to prevent memory waste and stale data issues. Implementation guidelines include evaluating query cost, frequency of access, data predictability, TTL settings, and scope management for optimal Redis performance.

Legacy Code And The Trap Of False Consistency

Maintaining consistency in legacy codebases can become a barrier to improvement when it preserves bad design patterns. Effective refactoring requires distinguishing between beneficial consistency and resistance to necessary change.

🚨 Introducing GemGuard: Automated Security for Ruby Gems (Scan, SBOM, Typosquat, Auto-Fix)

GemGuard is my attempt to make Ruby security less of a chore and more of a natural part of development. It scans your Gemfile.lock against OSV.dev and the Ruby Advisory Database, flags typosquat risks, and can even generate SBOMs in SPDX or CycloneDX formats. If it finds a vulnerable gem, it’ll suggest or apply safe upgrades, and because it’s designed with CI/CD in mind, you can drop it into your workflow without slowing things down.

The architecture of trust

Reliable system architecture emerges from patience and iterative refinement rather than upfront perfection. Key principles include embracing change, maintaining stability through resilience, and ensuring modifications don't break existing functionality.

The Cost of Code That Doesn't Belong

Code integration quality matters more than origin, whether human-written or AI-generated. Successful systems require contextual awareness, dialect alignment, and careful bridging between raw output and cohesive implementation.

How I approach a slow SQL query

SQL query optimization requires diagnostic thinking rather than checklist application. Effective performance tuning involves distinguishing between design issues and scaling problems through EXPLAIN analysis, indexing evaluation, filtering optimization, and concurrency assessment.
