Ruby on Rails development: MVPs and apps in productionMohammad Ali Jesar
I help startups launch MVPs on Rails, and add features and fixes to the Rails app you already run.
Who it is for
Startups and founders with an idea to turn into an MVP, CEOs and product teams with a Rails app that needs to move faster, and agencies that need a senior Rails developer.
Problems I solve
You have an idea and need the smallest working version that proves it, built so it can grow.
New features take too long to ship.
Bugs in production cost you customers or time, and nobody has time to dig into them.
Pages are slow, or background jobs pile up and fail without anyone noticing.
Your app runs on an older Rails version and needs a careful upgrade.
What I build
New Rails apps and MVPs on current Rails, from data model to deploy.
Features and fixes in existing apps, through pull requests your team can review.
Frontends with Hotwire or React.
REST and GraphQL APIs, and integrations with payment providers, CRMs and marketplaces.
Background jobs, performance fixes and Rails upgrades in small, tested steps.
Price and time
Features and fixes in your app, from $400, delivered in about 3 days.
Plan and demo app, from $800, delivered in about 1 week: a written plan (scope, architecture, costs, risks and a fixed price for the build) and a demo of one main flow. If you build with me, it comes off the build.
MVP with AI features, from $3,000, delivered in about 2 weeks: your first version, tested, plus 14 days of fixes.
Full web app, live, from $7,000, delivered in about 4 weeks: tested, documented and live on your own hosting, plus 30 days of fixes.
Ongoing work: part-time (20 hours a week) from $3,000 a month, or full-time (40 hours a week) from $6,000 a month. Monthly contracts get a lower rate because the hours are guaranteed.
Pay by the hour, or get a fixed price for a project, agreed before I start.
How a project runs
Read first: the code and tests of your app, or your idea and who it is for.
A written plan: scope, the smallest version worth building, and the risks.
Small pull requests with tests, so you can try each change as it lands.
Launch and hand-over: deployed, documented, and ready for your team to keep going.
Evidence
7+ years of production Rails for clients in the US and Germany.
MVP management tools for German clients in real estate and furniture, on Rails REST APIs.
Shopify and BigCommerce apps in Rails and React for US clients, with background jobs for catalog and order sync.
ai_shop_assistant: a Rails 8.1 app built from scratch with Hotwire, Solid Queue and streamed replies.
