Stand Out Now
You’re launching a new business or product and need to stand out.

You need high-quality design support without hiring in-house.
Struggling with slow design processes and inconsistent results? Check out my service and long-term Growth Partner Program.
Too Busy
You’re juggling a million tasks and don’t have time to focus on design.
Every moment spent figuring it out yourself is time away from growing your business. Focus on what you do best.
DIY Struggles
DIY website builders left you with bad design and wasted hours.
You can’t be an expert in everything. A poorly designed website doesn’t just waste your time—it can actively hurt your credibility.
Outdated Design
Your outdated website isn’t converting visitors into customers.
You get one shot at a first impression. If your website looks dated or the content feels stale, potential clients won’t stick around.
No Website, No Sales
You’re frustrated by missed sales opportunities without a website.
Lacking a landing page in today’s world means leaving $10,000s on the table.

My Background

4+ years designing for startups. I started at PLTWG Agency, designing for clients like Marvel and Zaybra. 

Next, I joined Pattern Brands, an NY-based e-com startup, where I worked on 7 different brands' websites, created a design system across all of them, optimized the funnel and conversion, and designed, built, and tested landing pages.

Collaborated with cross-functional teams and aligned business, design, and technical requirements. 23% conversion increases, 8% reduction in abandonment. Winner of HERIC and Dora scholarships for academic excellence.

Now applying this growth-focused approach to AI interface design through research and prototyping.

Let's Discuss Your Design Challenge

Whether you're building an AI product from scratch or improving an existing interface, I'd love to understand your users' needs and explore design solutions together.

Still have doubts?

Let’s put them to rest.

Great UX is essential for transforming complex product features into intuitive experiences that drive engagement, build trust, and deliver measurable ROI. 

UX design is especially important for AI products, as they are new to users, and they can get easily confused, distrustful, and leave. It’s the key to standing out in a competitive market.
This depends on the scope. For example, a UX audit is delivered within 2 weeks, while custom design work can take 4–10 weeks, depending on revisions. We work with you to set clear timelines from the start. Meanwhile the UX Retainer partnership can last 1 month, or forever, and you can cancel it whenever you need.
Client satisfaction is paramount. Each package includes up to two rounds of comprehensive revisions. If the design doesn't meet your expectations after these rounds, we'll have an in-depth discussion to realign the approach.
Before diving into design, I conduct an extensive discovery session. This involves understanding your brand's essence, target audience, competitive landscape, and unique value proposition. The result is a design that feels authentically yours.
Yes! While our initial packages have defined scopes, I offer ongoing monthly retainer services for startups needing continuous UX refinement and strategic design support.
Deliverables vary by service but may include UX audit reports, high-fidelity wireframes, A/B testing strategies, and prototypes. We will decide on deliverables during our discovery calls, to tailor them to your needs.
Absolutely. Whether you’re building your MVP or refining a live product, our services adapt to your needs. We focus on maximizing impact no matter your stage.
The payment is split into 3 parts: 30% deposit to book your slot in my production calendar, 35% at the start of the project, and 35% at the end of the project.
Absolutely. I understand the pace of startups and can tailor timelines to your needs while ensuring high-quality outcomes.
Custom design projects start with a deep dive into your product, audience, and goals. From there, I create designs, keeping you involved at every step to ensure alignment and satisfaction.
Depending on the project scope, I can typically start within 1–2 weeks of booking. Contact me to confirm availability.
