Special shout-out to my lovely team who made my summer in Seattle an absolutely unforgettable one!
✍🏼 Led 2 rounds of in-depth usability testing with 6 users
Received approval for research plan, managed 30-minute user interviews and moderated usability testing
Synthesized 60+ product-related asks from user feedback into actionable design specifications
🛠 Redesigned 8 key features under 4 user pain points that were shipped
Designed platform eliminating manual input errors and reducing steps for 2000+ AWS Finance users across 6 teams (in use now!)
⭐️ Collaborated cross-functionally with key stakeholders
Communicated on a weekly basis with product managers, designers, researchers, and engineers
Participated in 1-week org-wide hackathon, taking initiative to work with members outside of my team to contribute ideas for lasting impact

Project Overview
AWS PLATO
Product Library and Taxonomy Organizer (PLATO) is the single source-of-truth product definition system that generates product definitions according to a standardized framework and stores them for all downstream financial systems to consume from
Manage usage type divisor tool
Raw usage amounts for each AWS product SKU must be normalized so that usage can be reported in a consistent unit. The usage type divisor is the factor that makes this normalization happen.
Research plan
To map out my user interviews, I organized discovery sessions with stakeholders to learn about the current MVP and design objectives and worked closely with my PMs and mentor to align my understanding. I drafted and revised a PR/FAQ that includes background, research goals, evaluation process, users, pre-test and post-test questions, and tasks for users to prepare for my research.
Some tasks I had my users perform included:
View instructional side bar to understand functionality and terminology used in this site
Make a change to a service by inputting a new value to the usage type divisor and changing whether to include it in reporting
Navigate to and understand the meaning and significance of each column of data
Search for results with specific service code and usage type
Filter results to only show services onboarded in a specific time frame
Original MVP mockup of the Manage usage type divisors tool with limited features and ease of use

Ability to edit Usage type divisor value and Include in reporting

Keyword search

Filter by relative and absolute time range
Target customers
The target users are employees in AWS Finance, Sales and Marketing, and partners of the Finance teams.
User interviews
I conducted deep dives with 6 senior financial analysts and managers, walking them through user tasks and interview questions. I noted down the pain points they mentioned, successes and failures/setbacks of the user experience, and how efficiently each detailed user tasks were performed.
User research synthesis
I collected direct user testimonials that encompassed the main pain points that each HMW statement covered to best illustrate the emotions, level of urgency, and roadblocks involved in the current work process.
Design approaches
I used this framework to prioritize my design approaches and pinpoint specific use cases for each feature change.
Feature 1: Notifications
One of the biggest pain points was users not being able to receive immediate feedback after changing their data, so I edited the description to be more concise with visual icons and added the notifications feature.
Feature 2: Bulk edit
Many users brought up the use case of managing many service codes (up to thousands!) at the same time, which they needed to do 1-by-1 currently. I added the bulk edit feature to allow for more flexibility and efficiency when managing a large amount of data.
Feature 2: Bulk download
I added the bulk download feature in addition to bulk editing due to the popular use case of users needing to cross-check and audit changes in Excel, which requires swapping between the two platforms online and locally.
Feature 3: Activity log
I added the Activity log tab so that users have the option to view all changes being committed across the board. This way, managers can easily monitor which changes are being made and revert to previous versions if needed. This feature is used to tackle the common user pain point of not being able to override edits and especially not edits that others have made.
Feature 4: Version history
I innovated upon the static data and added links to each usage type divisor value, which brings up pop-up windows for every past value of the usage type divisor as well as the alias for the user who committed the change to facilitate easy communication.
Next steps and recommendations

Mobile prototypes
In the last few days of my internship, I played around with the mobile version of this prototype. Although there weren’t any previous mobile platforms created in AWS FinTech, this was an initiative which was discussed so I designed simple mockups in case mobile will be undertaken in the future.
Key takeaways
Ask the right questions to the right people
Everyone has a lot to offer in their respective areas of expertise, so being curious and throwing out questions can really help me grow. I’ve learned so much about UI best practices from designers, tips about interview questions from mentors, how to think about and break down big problems from PMs, and just general life wisdom from everyone!
Customer-obsessed applies to everyone
Amazon is extremely customer-obsessed, which has become a lesson I’ve taken with me for the rest of my design journey. However, I found that it applies to any scenario that involves people - in presentations, your audience is your customer; in interviews, the interviewer is your customer… to have someone listen means you need to speak from their perspective first.
