Back to original languageAbout Ruben
Founder of ONIQ Software, I help companies and startups design and develop their web tools, from POC to production application.
My playground: modern full-stack applications (React, Supabase), integrating AI (OpenAI, Mistral) directly into your products — chatbots, content generation, document extraction and analysis — and automating your processes via Make, n8n, and Zapier.
Specifically, I designed and deployed a complete SaaS platform: CRM with sales pipeline, Stripe payments, AI-powered live support, and custom business modules. I therefore master the entire chain: architecture, development, database, third-party integrations (HubSpot, Stripe, API), and deployment.
Beyond pure development, I also manage the growth dimension: SEO, conversion funnels, acquisition. If your project is out of the ordinary, just ask — we'll find a solution.
