TECH STACK
Workflow
I keep projects structured, collaborative, and fast-moving so you get quality results without unnecessary delays.
I discuss our client's demands, expectations, requirements, costs, time frames, and anything else the client needs.
In Figma, I design the initial user interface for the website, while also gaining feedback from the client.
I develop the website using Webflow's visual design tool, which if needed can be turned into HTML, CSS, and JS.
After the website has been developed and the client is satisfied with the result, I host it on the client's specified domain.
The Freelance Advantage
A lean, direct approach to building high-quality websites and products without the overhead or noise of a large agency.
No middlemen or miscommunications. You speak directly with the developer building your product, ensuring absolute clarity.
Bypassing corporate bureaucracy to move from a raw idea to functional, clickable software in days, not months.
From database architecture to frontend animations, I handle the entire stack to eliminate integration gaps.
I only take on select projects to ensure your product receives my absolute highest level of technical execution.
