Mobile and Web Application Development

$80/hr Starting at $1K

I help businesses design, build, and scale high-quality web and mobile applications that are secure, maintainable, and ready for real-world use.


With a strong background in full-stack development, I specialize in Angular, Java, Spring Boot, and Ionic, delivering end-to-end solutions — from intuitive frontends to robust backend systems and production-ready deployments.


Whether you need to build a product from scratch, improve an existing system, or prepare your application for launch, I bring a structured, reliable, and results-driven approach.


My services:

• Full-stack web & mobile app development (Angular, Ionic, Java, Spring Boot)
• Scalable backend architecture & REST API design
• Microservices and cloud-ready systems
• CI/CD pipelines, Docker & Kubernetes setups
• Database design (including geospatial/PostGIS when needed)
• API integrations and third-party services
• Performance optimization and codebase refactoring
• Production deployment and system hardening


Beyond coding, I contribute to improving product quality through clean architecture, clear documentation, and efficient development workflows. I also support teams with technical guidance and mentoring when needed.


I’m experienced working in Agile/Scrum environments and collaborating with international teams across different time zones.


Based in Brazil, originally from the Netherlands, and operating through my registered software consulting company — making international contracting simple and reliable.


If you're looking for a senior engineer who can take ownership and deliver solid, scalable solutions — let’s talk.
