What clients say
Fred was an absolute pleasure to work with on my sports app, Wager Vibes. He built the entire website from scratch and delivered a clean, professional, and fully functional product that looks and runs exactly how I envisioned. His communication was outstanding; he hit every deadline with time to spare.
Derek
Founder, Wager Vibes
Fred took my thoughts of something that I never knew I wanted and turned it into something that I don't know how I was living without. As someone that does part-time creation in full-time chaos, needing a website was never something I thought I needed; but I went to Fred with an idea and he turned it into reality.
Avery
Fred took the time to listen to every detail I wanted added and responded PROMPTLY. He didn't have an issue with any of my changes or additions.
Manny
The Collective
Fred was great and the website he created was better than I even pictured it would be. Thank you Fred, I will definitely work with you again.

Startup
Your website is the first investor meeting you don't know you're having.
By the time a partner gets to your pitch, three associates have already opened your homepage in tabs, scanned it for under a minute each, and formed an opinion that's basically locked in. Here's what they're looking at, what they're judging, and what to fix this week.

I audited 50 funded startup websites. Seven patterns showed up almost everywhere.
Two weeks. 50 sites. Pre-seed through Series C. The same mistakes over and over. Here's the aggregate data, the patterns, and what the top five sites did differently.

I redesigned 1Password's homepage. Here's every decision I made and why.
This is an unsolicited concept redesign. No affiliation. No briefing. Just a designer looking at a category-leading product with a homepage that hasn't kept up with how its competitors now look, and walking through the redesign decision by decision. I also built a second concept, fully live, for 1Password's Extended Access Management push.
