Mykl C.
Rails Developer | Internal Tools, Spreadsheet-to-App & AI Automation
Most businesses I work with run on a few spreadsheets, a lot of copy-paste, and one person who knows how everything really works. I turn that into software that fits how your team actually operates, so the work gets faster and the knowledge doesn't walk out the door when someone leaves. I've spent 10+ years building web applications, mostly in Ruby on Rails. I start with the business problem: what it's costing you in time, errors, or missed follow-ups. Then I build the simplest thing that fixes it and take it from idea to deployment. Typical projects: - Turning a spreadsheet or manual process into a web app your team can rely on - Internal tools and admin dashboards for operations, quoting, scheduling, and reporting - Cutting out double data entry by connecting the systems you already use (APIs, webhooks, Zapier) - Practical AI features and prototypes, like document processing, drafting, and search over your own data - MVPs for founders who need a working product, not a slide deck - Rails upgrades, cleanup, and ongoing support for existing apps How I work: I talk directly with the people who use the process, map out how it really works, and agree on a small first milestone so you see something working early. I build with AI tools, which lets me move faster, while I handle the architecture, decisions, and quality myself. AI is the tool. Understanding your business is what makes the software work. Tech: Ruby on Rails, Hotwire/Turbo, PostgreSQL, JavaScript/TypeScript, React, Tailwind CSS, GraphQL, Sidekiq/SolidQueue, ActionCable, RSpec/Minitest, Stripe, Twilio, Mailgun, Google APIs, OpenAI APIs, Zapier, Heroku, Cloudflare, GitHub Actions. If your team is fighting a spreadsheet, retyping data between systems, or relying on one person's memory to keep things running, send me a message with a short description. I'll tell you honestly what I'd build first.
