fix and scale ruby or nodejs backend apps

Informazioni su questo servizio

I build full-stack web apps with Ruby, Node.js, and modern JavaScript.


With 6+ years of experience, I help startups and product teams ship reliable features end to end from database and APIs to the UI your users actually click.


What I can do for you:

Full-stack features in Ruby on Rails + frontend

Node.js / TypeScript APIs with a clean web UI

Vue.js / JavaScript frontend work tied to real backend logic

Auth, dashboards, admin panels, CRUD workflows

PostgreSQL / MongoDB, Docker, AWS integrations

Payments (Stripe) and third-party APIs

Bug fixes, refactors, and tests (RSpec / Jest)

Production-ready source code with comments


How we work:

1. You share the goal, stack, and current codebase (if any)

2. I confirm scope for the package (~10-12 hours)

3. I deliver working full-stack changes + source

4. Up to 2 revisions included


Best fit: new features, MVPs pieces, integrations, admin tools, and fixes across frontend + backend.


Message me before ordering if the task is larger we can plan milestones or a custom offer.
