AI-First Design & Prototype
FemCare ChatBot
With the rise of AI, I have refined my skillset to include quick MVP development and prototyping solutions. I created a chatbot for women’s health for them to get evidence-based information about women’s health from reliable medical sources.
I used Figma, Replit, OpenAI, Firebase.
Instant Networking App
I developed an instant networking web app that allows users to create a profile, save contact and swap contact instantly at networking event.
I used Visily.ai and Replit.
FemCare Landing Page
I designed a landing page for femcare and developed it using Lovable.dev. In the process I used my prompt engineering skills and got to refine it to get the output that was designed on Figma.
I used Figma and Lovable.

Mar 2023 - Mar 2025I have worked with Sarah for over 2 years now. Her contribution to our channel has assisted its growth and development more than had been done in the previous 4 years. Sarah provides a fresh new approach to design and customer focused elements to build seamless efficient customer experiences that to this day receive praise. Sarah has a fantastic work ethic, and she strived to deliver her best work in the most efficient manner, she always accommodated me and my numerous requests to explore multiple possibilities and change designs all while adhering to very stringent design standards. Her willingness to always help, to listen, think and contribute even on items that were not directly hers made Sarah an invaluable asset to the team. Sarah will be missed and wishing her nothing but success in her next chapter, though in her case i definitely think her hard work will speak for itself again.

Mar 2021 - Apr 2022I've had the pleasure of working with Sarah as a design partner and manager in the recent year. Sarah is such a great collaborator, bringing along with her a strong set of design skills, a bright personality, and an unmatched work ethic. During our time together, Sarah took part in highly intensive collaboration sessions between product and design to gather information, understand the users, and help shape the features in our product that solved real problems. I'm confident that no matter what team is lucky enough to work with her, she will bring the kind of UX/collaboration skills and experience needed to help that team succeed!

Mar 2021 - Apr 2022I've worked with Sarah for over a year at Upland. She quickly adapted to new workflows and tools while handling the ever-changing requirements of a complex project. Her background and skills make her effective at finding solutions that meet users' needs, development constraints, and business goals. Her drive to improve existing systems extended beyond the design scope: she was instrumental in improving the UX team's onboarding process and made significant contributions to our shared tools. I will miss working with her every day. She's a talented designer, and I expect to see her thrive in every challenge she decides to take on next.

Building a Women’s Health Chatbot with Replit
Over the weekend, I designed and prototyped an idea I had.
The idea?
To create a safe, judgment-free digital space where women can ask health questions, get reliable answers, and feel seen, especially in places where access to care is limited or stigma makes it hard to speak up.
What I built (and how): A web app with login and a built-in women’s health chatbot.
Designed a clean interface with Figma
• Developed on Replit for speed and flexibility
• Used Firebase for authentication and secure login
• Integrated OpenAI for conversational AI (trained with curated women’s health content for accuracy)
The result?
A functional prototype that shows what’s possible when you combine design, tech, and empathy in women’s health.
This isn’t a live product yet. But it’s a starting point to explore how tech can support women’s health with empathy, privacy, and accessibility in mind.
While building the prototype, I focused on:
• Understanding kind of questions women struggle to ask
• Designing flows that feel calm, respectful, and intuitive
• Testing tone, logic, and clarity in chatbot conversations (still needs improvement)
• Thinking about how this might work in culturally sensitive contexts
If this were to go live, here are a few things that would be non-negotiable:
✅ Data Privacy & Compliance
• Full HIPAA compliance (US): This ensures that protected health information is encrypted and secure
• GDPR compliance (UK/EU): This ensures clear consent, the right to be forgotten, and transparent data handling
• Minimal data collection: only what’s necessary, nothing more
✅ Medical Accuracy
• All chatbot responses would need review by certified professionals
• Clear disclaimers that it’s not a substitute for professional care — more like a first step toward it
✅ Bias & Inclusion
• Training data and design must reflect diverse health experiences, inclusive of different cultures, identities, and backgrounds
• Language must be plain, neutral, and stigma-free
✅ Accessibility
• Support for screen readers, voice input, and low-bandwidth environments
• Additionally, multilingual support would be important for indigenous or underserved communities
This prototype is just the beginning, but I’m excited about where it could lead.
