Services
Expertise to help your team ship faster and with confidence
I offer backend-focused consulting services for small tech teams looking to reduce costs, fix slow pipelines, and ship with confidence.
Fractional Ruby on Rails Engineer
Need senior-level Rails expertise without the full-time commitment? I join your team part-time to ship features, tackle tech debt, and keep your codebase healthy.
- Ship features and fix bugs alongside your existing team
- Code reviews that improve quality and share knowledge
- Technical guidance on architecture and best practices
- Tackle tech debt and improve codebase maintainability
Heroku to Kamal Migration
Heroku bills adding up? I help Rails teams migrate to self-hosted infrastructure using Kamal, typically cutting hosting costs 60-80% while keeping deployments simple.
- Full migration from Heroku to your own infrastructure
- Kamal setup for zero-downtime deployments
- Database migration strategy with minimal downtime
- Documentation and training for your team
CI Pipeline Optimization
Slow CI kills momentum. I help teams speed up their test suites and CI/CD pipelines so you can ship faster with confidence.
- Test suite audit and optimization
- Parallel test execution and smart test splitting
- Docker and caching optimizations
- Flaky test identification and fixes
Testing Audit
Your testing process should give you confidence, not slow you down. I audit Rails applications to help sort out test flakiness, bad patterns, performance bottlenecks, and gaps in your testing strategy, then give you a clear plan to fix them.
- Identify flaky tests and intermittent failures
- Find slow tests dragging down your workflow
- Review test structure, patterns, and manual testing gaps
- Deliver a prioritized report with actionable fixes

"Dennis provided exactly the type of expert guidance we desperately needed. He looked at our situation and within hours was able to tell us why what we were trying to do wasn't working and gave us alternative solutions."
