Description

Ruby on Rails and React developer, I design SaaS, business tools, and automations for startups, SMEs, and agencies.

Specifically, I deliver:

- Web and SaaS applications in Rails/React, from MVP to revenue-generating versions

- Internal back-offices and dashboards that replace overflowing Google Sheets

- APIs and integrations with your existing systems (ERP, CRM, business tools)

- n8n automations and AI agents for your recurring workflows: payments, notifications, data synchronizations, repetitive manual tasks

- Mastered cloud deployments: Docker, CI/CD, VPS

I also take on existing projects: audits, redesigns, feature additions, and fixing fragile codebases.

My method: understand the business problem before writing code. I deliver incrementally, with tests on critical components. You know what's progressing each week.

Free initial consultation to define your needs, followed by a phased quote.
