About Roberto Antonio
Full Stack Developer | SaaS, APIs, AI Integrations & Automation
Maia, Portugal - 5:48 am local time
I'm Roberto Machado, a Software Developer based in Portugal with 5+ years of professional experience designing, developing, and maintaining software solutions for e-commerce, logistics, IoT, and SaaS businesses.
I specialize in building custom software, SaaS platforms, internal business systems, AI-powered solutions, and complex integrations. I don't only write code — I take projects from idea to production: defining architecture, designing databases, developing backend and frontend systems, integrating external services, deploying applications, and continuously improving them.
Currently, I work as a software developer for a major e-commerce company in Portugal, while also being the sole developer responsible for the technology of a delivery company in Porto. In this role, I make technical decisions, design new features, optimize existing systems, and build solutions that improve daily business operations.
Some of the problems I help companies solve:
• Automating repetitive business processes to reduce operational costs
• Building SaaS platforms from concept to production
• Developing internal management systems and dashboards
• Integrating third-party platforms and APIs
• Creating AI-powered tools and chatbots
• Improving performance and scalability of existing applications
• Modernizing legacy systems and improving workflows
Recent projects and results:
• Developed an AI chatbot for a delivery company that reduced customer support requests by more than 70% by automating repetitive interactions.
• Built and maintain business-critical systems for a logistics company, including workflow improvements and billing process optimization.
• Designed and developed a complete multi-tenant SaaS platform for restaurants from scratch. The platform includes restaurant management, digital menus, online ordering, Stripe payments, delivery platform integrations, optimized image handling, subdomain-based stores, and administration dashboards.
• Worked on an IoT platform for a Chilean startup that processes continuous streams of measurement data, requiring optimized rendering, real-time visualization, charts, and aggregated analytics.
My technical experience includes:
Backend:
PHP, Laravel, CodeIgniter, Node.js, NestJS, REST APIs, SQL
Frontend:
JavaScript, TypeScript, Vue.js, modern web interfaces and dashboards
Databases:
PostgreSQL, MySQL, database architecture, data modeling and optimization
Infrastructure:
Docker, Git, deployment workflows and application maintenance
Integrations:
Stripe, Google Maps, Uber APIs, Onfleet, OpenAI/ChatGPT integrations, webhooks and third-party services
AI Development:
AI chatbots, LLM integrations, business automation workflows, and practical AI solutions focused on improving operations.
I work with startups, small businesses, and companies that need a reliable technical partner to build, improve, or automate their software.
If you need someone who can understand your business challenges, make technical decisions, and deliver a complete solution — from architecture to production — I would be happy to discuss your project.
