I’m a full-stack developer with over 10 years of experience, focused on building SaaS applications. I work mostly with Ruby on Rails, React and Postgres, and I’ve handled everything from backend to deployment to analytics. I’ve built and maintained apps like HTTPScout, an uptime monitor, doing everything from writing the code to setting up the infrastructure. I enjoy taking on big projects, and I’m used to figuring things out as I go. I’ve run my own small ventures, worked as an engineering manager at PagerDuty, and understand both the technical and business sides of software. I like clean, simple solutions that work. I’m also experienced with DevOps and prefer keeping things well-documented. If you need someone who can build and launch a project end-to-end, I'd love to chat.

I help web development teams go further. I focus on practices that facilitate a leaner journey towards profitable and maintainable software. My goal is to help create efficient, sustainable solutions with people with a long-term vision. Here are some of the ways I've done this in the past: Stepped in mid-project to lead to success the 6-person team in charge of a flawed but critical migration task. Led and mentored people at all experience levels, including small business owners seeking practical, self-managed solutions, early-career developers joining new teams, and experienced developers transitioning to new technologies. Established and evolved the delivery process blueprint for development teams of a freelance collective I co-founded and actively participated in for seven years. Optimized application performance, improved test coverage, enhanced email delivery, facilitated cross-team communication, and strengthened security posture Reviewed countless pull requests, resolved numerous issues, and delivered even more features working closely with internal teams, Advised against hiring me and proposed alternatives when what I bring would not have helped. Although I prefer longer engagements, as I'm convinced the cumulative effect of small, consistent adjustments in the right direction offers more lasting benefits, I can rely on a hard-earned ability to quickly comprehend complex code bases and project contexts to bring meaningful improvements on shorter commitments. I can work in parallel to your project team, delivering high-impact quality of life improvements that often get sidelined, but also integrated into a team as a lead or software engineer, or for shorter engagements, independently, focused on resolving a specific pain point.

I'm a Ruby on Rails engineer with over 9 years of experience designing and developing REST APIs, SSO authentication, integration with 3rd party services, and performance optimization. Being detail-oriented and having good communication skills, I can collaborate well with any team to deliver high-quality products.

I love working on extremely challenging problems. Specifically very difficult bugs. In addition, I have 10 years of professional development experience in rails.
