Ever felt your software could do more for your business? You're not alone.
Many startups have world-changing ideas but struggle to build a natural software experience for their customers and teammates. People get lost, feel overwhelmed, or just give up. You need an interface that is easy for everyone to use and helps to provide value for your business. That's the gap I bridge. I help innovative startups design software that users love from day one. Here's what I've done so far:
❇️ Boosted four startups (case studies below) from zero to $10 million+ in total funding with stellar UX.
❇️ 10+ years of design experience, turning ideas into user-friendly software.
❇️ Collaborated with 100s of people worldwide over the past half a decade.
❇️ Consulted with organizations like Duke University Hospital, University of California: Berkeley, North Carolina State University, Wake County Public Schools, Bloom Institute of Technology, TARGAN, SRAM, and 10+ more.
Are you eager to enhance or start your software? Reach out, and let's start a conversation about your experience.
P.S.
While it's my job to talk about my client's success, not myself, I guess it's fair to give a short introduction to me too:
I'm an experience (UX) director wizard living in Raleigh, NC. When not designing, you can find me sweeping triathlons, exploring outdoors, or eating peppers off my jalapeño plant. 🌶️

🏆Featured on Upwork Success Stories
📈7 Years On Upwork
🌟 I help businesses run smoother, communicate better, and grow faster — and I've been doing it for over 8 years across client management, social media, writing, and virtual support.
My background spans a range of roles that, taken together, make me a rare find: I can manage your client relationships with professionalism and care, run your social media with strategy and consistency, write copy that actually converts, and handle the behind-the-scenes operational work that keeps everything moving. Most clients don't need five different freelancers — they need one reliable person who gets the full picture. That's what I bring.
Client & Account Management: I've spent years serving as the primary point of contact for clients across industries, managing expectations, running check-ins, resolving issues, and making sure no one ever feels left in the dark. I'm organized, responsive, and calm under pressure.
Social Media Management: From content calendars and caption writing to scheduling, community engagement, and performance reporting, I handle social media end-to-end. I've managed accounts across Instagram, Facebook, LinkedIn, TikTok, and Pinterest for brands in e-commerce, wellness, real estate, and professional services.
Virtual Assistance: I'm the person behind the scenes who makes sure the inbox is clean, the calendar makes sense, the deadlines are met, and nothing falls through the cracks. I've supported founders, executives, and teams with everything from email management and research to CRM updates and project coordination.
Writing & Copywriting: Whether it's a website, an email sequence, a blog post, or a product description, I write with clarity, purpose, and the reader in mind. I adapt my voice to fit your brand and I deliver work that doesn't need three rounds of heavy edits.
Experience:
• Client Management
• Project Management
• SEO Writing, Content Writing, Blog Writing, and more
• Digital Marketing
• Social Media Growth and Management
• Keyword Research
• WordPress
• Google Analytics and Google AdWords
•Email Marketing
*Please note that my job impact score is not a true reflection of my client's satisfaction, but a culmination of Upwork's ever-changing algorithim that I have not kept up with once I took a break from the platform. I am happy to provide client references!*

I started my journey to becoming a professional Nerd by discovering I was a mediocre graphic designer. I spent part of the intervening years operating a one-man Mac consultancy, and the rest honing my writing, presentation, and automation skills. Today, I may or may not be a self-aware collection of bash scripts.
