I enjoy working with AB testing because it licenses ideation and explorations for innovative design, and recognizes impact. Scroll down to see examples.
Personalized accessory recommendations
A great collaboration, this business team would start with a strong premise and open up for variations to approach AB testing for personalized accessory recommendations based on most popular devices (unauthorized users) and customer-specific devices (authenticated). 
Explorations included personalized marquees and features on the landing page, followed by list pages with personalized device and accessory filters.
Personalized device marquee 
We explored various approaches to promoting personalized accessory recommendations, starting with a marquee.
Personalized device page
Upon selecting from a list of their devices, the customer then goes to an accessory recommender page.
Personalized accessory recommender carousel 
I combined a personalized header and drop downs that allow the customer to choose various categories of accessories and specify from multiple devices.
Deal promotion and sticky navigation
The business team was looking for opportunities to promote deals within a sticky navigation to follow page scrolling. 
Amongst several other approaches, I designed and proposed floating carousels to accompany the deals widget. View explorations.​​​​​​​​​​​​​​
Marketing promo tiles
I found opportunities to apply existing responsive components, including use of our more colorful promo tiles (grey, green, blue - accessibility-compliant colors) which achieved greater than 95% click-through rates compared to the previously colorless marketing banners (see below). 
The product detail pages were not part of the RWD development effort, but the layouts were based on the same style and grid, so I recognized that we could carry over the same components.
Here is the original colorless version of the marketing promos (inside the gray horizontal block) which were getting no click throughs.
Product detail pages: Collapsable tables and scannable iconography
Contributed to several aspects of product detail page redesign, used for devices and accessories. Created layouts in alignment with our responsive grid and reduced sprawling device details to collapsable, scannable tables.

Analysis: Capone VS Citi online credit card payment
Received a request for comparison of online transaction experiences. I immediately thought of the contrast between my experiences in paying my two credit cards online, and detailed why CapitalOne provides the cleaner, more effortless experience and feeling.

CapitalOne:
• Payment flow contained in a short, narrow modal with dimmed background
• Flow progresses through one consistent screen format
• Information relating to payment is focused and concise, minimal verbiage
• Use of color / bold typography further emphasizes action, separates / focuses information
• Icons/color offer visual cues / indicators, feels intentional, like an app unto itself vs an auto-generated form
• Minimal calendar, compare with wider Citi version: The Citi calendar affords next month without additional click, but minimal is better overall
• Noticeably painless, simple, bold and colorful
• Sections posed in the form of a question, use of plain language
• Compare verbiage: Capone vs Citi How much do you want to pay? vs Select your payment amount: a guiding question inviting user to identify from multiple choice vs select which is a rigid and burdensome

• Make a payment vs Setup your payment: make connotes immediacy vs setup sounds like you might want to bring a lunch

Citi:
• Long scrolling, disconnected parts, feels like an auto-generated form
• Reads as busy, text-driven, sprawling, nothing commands attention
• Minimal use of color for any purpose – emphasis or esthetics, and a nasty variation on green
• Header is thin font, separated from action
• Wider format accommodates more text
• A lot to read, small text, harder to read, white backgrounds
• Confirmation screen changes format
• Possibly offers some additional info but overall feels busy
