Frequently Asked Questions

Common questions about custom internal apps and automation

An Internal App and Automation Specialist designs and builds custom software solutions that streamline your business operations. Unlike off-the-shelf SaaS tools, I create tailored systems that match your exact workflows, automate repetitive tasks, and integrate seamlessly with your existing processes, helping teams eliminate manual work and improve efficiency.
Every project is different, so pricing is tailored to your specific requirements and complexity. Factors include the number of features, integrations needed, data complexity, and user roles. I provide transparent quotes with no hidden fees after understanding your needs through a discovery call.
Projects begin with a discovery phase to understand your workflows and requirements. I then work in iterative sprints so you see progress regularly and can provide feedback throughout. This ensures the final solution matches your needs exactly and your team can start benefiting from core features as they're completed.
Custom internal apps are built specifically for your business processes and can evolve with your needs, while SaaS tools force you to adapt to their workflows. Custom apps eliminate monthly subscription fees, provide full data ownership, and integrate exactly with your existing systems. However, SaaS works well for standardized needs like email or basic CRM.
I specialize in operational automation for travel agencies, money changers, spas & wellness centers, villas & property management, and small service businesses. Common projects include booking systems, inventory management, financial reporting dashboards, client portals, and workflow automation that connects tools like Notion, Google Sheets, and email.
No. I design all apps with non-technical users in mind. The interface is intuitive, similar to familiar tools like Google Sheets or Notion. I provide training documentation and video walkthroughs for your team, plus post-launch support to ensure smooth adoption.
