Over deze dienst

Have an idea but don't know where to start? Let's build it together!


We transform business ideas into production-ready software from MVPs and internal tools to full-scale web applications and APIs.


With a development team with extensive experience in Node.js, .NET, Spring Boot, React, and Python, we create fast, easy-to-maintain systems that are ready to adapt to the growth of your business.


What I deliver:

  • Custom web applications (frontend + backend)
  • RESTful APIs and microservices architecture
  • Database design and optimization (PostgreSQL, MongoDB, MySQL, Oracle) - Third-party integrations (Stripe, Twilio, Google, AWS, etc.)
  • Clean Code, SOLID principles, and modern design patterns


Powered by DoubleS Software Solutions I personally lead every project to ensure quality communication and technical excellence. Our team of senior developers accelerates delivery while maintaining code standards.


Perfect for:

  • Startups building their MVP
  • Companies automating internal processes
  • Businesses needing custom integrations
  • Teams requiring technical co-founders or CTO-level guidance
