About

Professional summary

I am a product designer and AI experience designer with more than five years of experience taking digital products from early concepts to launch. I specialize in user-centered UX/UI, conversational AI experiences, and product strategy that balance user needs with measurable business outcomes.

I design and build products end-to-end, covering discovery, information architecture, interaction design, visual design, prototyping, product architecture, monetization, and go-to-market. I have independently launched SaaS products, web apps, PWAs, and Chrome extensions across AI, climate technology, accessibility, productivity, and family technology.

I work extensively with AI-powered product experiences, including LLM-driven conversational flows, generative AI design workflows, and Claude API integrations. My approach combines human-centered design, accessibility awareness, user research, analytics, and experimentation to improve activation, conversion, and retention.

I have led design for startups, nonprofits, education providers, and SaaS teams. My work has included mobile and web product design, brand positioning, growth marketing, landing pages, onboarding flows, paywalls, and developer handoffs.

I am comfortable connecting product strategy with execution, using tools such as Figma, Next.js, Supabase, Firebase, Vercel, Stripe, and analytics frameworks. I am motivated by building practical, intuitive products that solve meaningful problems and create measurable value.

Career history

Independent Product Designer and Builder Self-directed

I independently designed, built, and launched six products: KLIMAT-P, IncluRead, Distill, Desk Wellness Pack, NameMyTab, and Frostly. These products span AI-driven data platforms, Chrome extensions, and progressive web applications.

I owned the full product lifecycle, including problem discovery, UX/UI design, architecture, backend development, monetization, and go-to-market. I also developed a KPI Funnel Framework that connects user journeys with analytics sources, benchmarks, and success metrics across product, paid acquisition, and organic growth channels.

I shipped production products using Next.js, Supabase, Firebase, Vercel, Stripe, and the Claude/Anthropic API, working with real monetization and data-integrity requirements.

Senior Experience Designer and Content Strategist ZIEL AG - Zack

I owned product strategy, UX/UI, brand positioning, and growth marketing for Zack, a smart family organizer available across iOS, Android, and web. I contributed from product architecture through go-to-market for a live consumer app.

I used funnel data to identify the post-install drop-off before registration, reduced onboarding friction, and designed paywall and trial logic. I also designed and optimized LLM-driven conversational flows for the product.

I ran Meta and LinkedIn campaigns end-to-end, achieving competitive CPC and CPM results while reaching approximately 290,000 unique people on a lean budget. The product reached more than 100 Google Play installs, while website sessions averaged 4 minutes and 18 seconds.

Lead UX/UI Designer, Web and App Tanzania Health and Medical Education Foundation

I designed the AHADI mobile mental health app and prepared specifications for developer implementation. My work focused on creating an accessible, user-centered digital health experience.

The app became a finalist in the 2024 EUTECH SDG Awards under SDG 3: Good Health and Well-being. My design contributions helped the foundation save more than $18,000 in costs.

UX/UI Designer, Web Confidential SaaS Project (Leading SaaS Tech Company, with Cielo Team)

I led the UX/UI design and implementation of a responsive landing page for an AI-driven manufacturing optimization tool. The product incorporated real-time data and predictive-maintenance functionality.

I collaborated with cross-functional stakeholders to translate complex product capabilities into a clear, conversion-oriented web experience.

UX/UI Designer Specialist OpenBootcamp

I reviewed student UX/UI assignments and provided actionable feedback aligned with course standards. I supported learners in improving design reasoning, usability, and execution.

I also created and facilitated live Figma workshops for an e-learning audience.

UX/UI Web Designer California Elder Justice Coalition

I rebranded and redesigned the coalition website with a focus on accessibility and clear communication. I created prototypes in Figma and implemented the website in Weebly.

The redesign helped the organization save $4,212 in costs.
