HOW I WORK
Discovery & Planning
We start with conversations to understand your business needs and goals. This includes reviewing what you currently have, identifying what's working and what isn't, and setting clear targets for success. You'll receive a detailed plan with realistic timelines and costs upfront.
Design & Prototyping
Initial sketches and layouts help visualize the solution before any coding begins. These evolve into clickable prototypes you can test on different devices. Your feedback at this stage ensures we're building exactly what you need.
Development & Testing
The actual building happens with clean, organized code that's easy to maintain. Every feature gets tested thoroughly across browsers and devices. You'll see regular progress updates and have opportunities to review and request adjustments.
Deployment & Support
Your project goes live with proper hosting setup and necessary configurations. You'll get clear documentation on how everything works and training if needed. After launch, I'm available to fix issues, answer questions, and help with future updates.
