Chi sono
👋 Hi! I'm Víctor, a full-stack web developer from Spain.
I build modern, responsive websites and SaaS dashboards using React, Node.js and clean code — not templates. My latest project, Markulia, is a SaaS platform I built end-to-end: React frontend, custom Node.js API, real-time quota system, admin panel, Stripe billing and VPS deployment.
🛠️ Stack: React · Node.js · REST APIs · Stripe · Tailwind · OpenAI/Claude APIs
I also integrate AI into web apps: chatbots, automations, LLM features.
✅ Clear communication · On-time delivery · Revisions included

During my internship I worked as Full-Stack Developer on Markulia, a complete SaaS management platform for handling communication campaigns, phone numbers, billing and account usage from a single modern dashboard. I designed, developed and deployed the entire application end-to-end. Key responsibilities and achievements: • Built the entire frontend in React with a custom layout system, reusable UI components and a fully responsive design optimized for desktop, tablet and mobile. • Developed and integrated the backend API (Node.js / REST) handling authentication, data processing and business logic with secure client-server communication. • Implemented a complete real-time user quota system with usage tracking, limit enforcement and clear user feedback on remaining allowance. • Created a protected admin panel allowing administrators to manage users, adjust quotas and oversee platform activity and revenue. • Integrated Stripe for secure payments: balance management, top-ups and usage-based packages — fully self-service for end users. • Integrated Twilio for instant phone number provisioning (Local / Mobile / Toll-free) across multiple countries. • Configured and maintained the production deployment on a VPS, including build pipeline, backend process management and zero-downtime restarts. • Maintained an automated changelog and structured release process, keeping every feature and fix documented. I handled the complete development lifecycle — from requirements and architecture to coding, testing, deployment and ongoing maintenance — while keeping clear and consistent communication. The platform is in production serving real users.
