Frequently Asked Questions

Common questions about working together

How long does a typical engagement last?

It depends on the project scope. Short-term audits or fixes typically take 1-2 weeks. Feature development projects range from 4-12 weeks. I also work with several clients on ongoing retainer arrangements for continuous support and development. My longest client engagement has been over 3 years.

Do you work remotely or on-site?

I work 100% remotely. I've successfully collaborated with teams across different time zones (US, Europe, Australia) for over a decade. I use asynchronous communication effectively and am flexible with meeting times when overlap is needed.

What's your hourly rate?

Rates depend on the project type, complexity, and engagement model. I offer hourly consulting, fixed-price projects, and monthly retainers. Let's discuss your specific needs on a call — I'll give you a clear proposal with no surprises.

Can you work with our existing team?

Absolutely! I've worked embedded within teams of all sizes (2-200 engineers). I adapt to your existing workflows, participate in code reviews, and document everything so your team can maintain the work. I'm also happy to mentor junior developers and share knowledge along the way.

What's your availability?

I typically have availability for new projects within 1-2 weeks. For urgent needs, I can sometimes accommodate faster starts. Book a call and we'll discuss timing — I'll be upfront about my current capacity and when I can start.

Do you handle emergency fixes?

Yes, I've helped teams with critical production issues and urgent fixes. If you have an emergency, reach out and I'll do my best to help quickly. For ongoing clients, I prioritize their urgent needs.

What technologies do you work with?

Primary: Ruby on Rails, Ruby, PostgreSQL, Redis, Sidekiq, RSpec
Frontend: Hotwire/Turbo, Stimulus, React, Vue.js, Tailwind CSS
DevOps: AWS, Docker, GitHub Actions, CI/CD
APIs: REST, GraphQL, Twilio, Stripe, OpenAI/LLMs
