I help businesses identify operational problems, design practical solutions, and build the software needed to support them. With 10+ years of experience building web applications, internal tools, workflow systems, MVPs, and automations, I focus on delivering measurable business outcomes rather than simply writing code. I work directly with stakeholders and routinely take projects from idea to deployment. My background is rooted in Ruby on Rails development, but I frequently work across the entire product lifecycle—from requirements discovery and architecture through implementation, deployment, and ongoing support. I work directly with stakeholders to understand the underlying business problem, evaluate options, and determine the most effective path forward. Depending on the situation, the right solution may be a custom web application, workflow automation, API integration, AI-assisted process, dashboard, reporting system, or a combination of several technologies. Areas of expertise: • Ruby on Rails development • Full-stack web applications • Internal business tools • Product development and MVPs • AI-assisted workflows and automation • API integrations and webhooks • Database design and optimization • Business process automation • Technical consulting and solution design Technologies I've worked with include Ruby on Rails, PostgreSQL, Hotwire, JavaScript, HTML/CSS, Tailwind CSS, Stripe, Mailgun, Twilio, Google APIs, Zapier, OpenAI APIs, Heroku, Cloudflare, GitHub, and many others. I enjoy working with clients who need more than just code—they need a partner who can understand the business problem, evaluate tradeoffs, and build an effective solution.
