★ Case study 01 · E-commerce

How it went down

01 The Challenge

  • Their bounce rate was 72%.

Design isn't decoration. It's a revenue driver. Every pixel should have a purpose.

★ Case study 02 · SaaS

Complexity is easy. Simplicity takes work. But simplicity is what users pay for.

★ Case study 03 · Mobile Design

Transformed a frustrating app into users' favorite tool. Complete UI overhaul that turned critics into advocates.

Mobile App: 4.2 to 4.8 Star Rating in 60 Days

Mobile design isn't just shrinking desktop. It's rethinking the entire experience for thumbs and glances.

★ Case study 04 · Landing Page

Landing Page: 12% to 34% Conversion Rate

Redesigned a landing page that tripled signups. A/B tested redesign that became the company's best-performing page.

The receipts

Landing Page: 12% to 34% Conversion Rate
Landing Page: 12% to 34% Conversion Rate

How it went down

01 The Challenge
  • The SaaS company was spending $50K monthly on ads but only converting 12% of visitors.
  • The landing page had too much text, unclear value proposition, and weak CTAs.
  • Visitors were leaving confused about what the product actually did.
02 The Strategy
  • I redesigned with a single focus: make the value crystal clear in 3 seconds.
  • Created a bold headline that stated the benefit directly.
  • Added a demo video above the fold.
  • Simplified the page to 4 sections: problem, solution, proof, CTA.
03 The Result
  • Conversion rate jumped from 12% to 34% (283% increase).
  • With the same ad spend, they went from 600 to 1,700 signups monthly.
  • Revenue increased $180K monthly.
  • The page became their template for all future campaigns.

Clarity beats creativity. If visitors don't understand your value in seconds, you've already lost.

★ Case study 05 · Design System

Built a design system that made the team 10x faster. Created a scalable system that unified the product and accelerated development.

  • Designers were recreating components from scratch.
  • Developers were asking 'which blue?' daily.
  • Design-to-development handoff took 2 weeks per feature.

A design system isn't just components. It's a shared language that makes teams move faster.
