Listen, Think, Feel
DESIGN
I'm a Warsaw-based UX/UI/Product Designer, AI Experience Designer, and Product Builder, working across the full product lifecycle from UX and conversational design through go-to-market, CRO, ASO, and KPI strategy. Design decisions will stay grounded in what's actually converting.
I design and build digital products end-to-end, with a focus on AI-powered experiences but always with a user-first approach.

KLIMAT-P
Seasonal Weather Probability Platform
Product strategy + Positioning + UX/UI + Dashboard design + Landing page design + Frontend development + Data architecture + Product development
Built around a Bayesian seasonal probability model, combining historical climatological baselines with live data from IMGW-PIB, NOAA CPC, and teleconnection indicators (ENSO, NAO, AO) to estimate seasonal risks such as drought, frost, heat, and precipitation anomalies.
To ensure transparency and trust, forecasts are publicly self-verified against real-world outcomes through weekly validation and Brier score evaluation, allowing users to see not only predictions but also how accurately the model performs over time.
Led the product end-to-end: market positioning, UX research, information architecture, visual identity, landing page and dashboard design, frontend implementation, data architecture, bilingual experience, and deployment.
Designed two intentionally different experiences:
-
a calm, trust-building marketing website focused on credibility and education
-
a dense operational dashboard optimised for frequent daily use and decision-making
Outcome: Public beta launch with 8 Polish regions, live government and international weather datasets, weekly verification against actual outcomes, and a fully operational end-to-end platform built by a solo designer/developer.
Zack: AI-Powered Family Organizer
Product strategy + Brand positioning + UX/UI + mobile app design (iOS, Android) + website design + Growth marketing (iOS, Android, Web)
An AI-powered family organizer that captures tasks from voice, text, and email, and turns them into shared action, helping households stay ahead of school admin, appointments, and everyday planning, together.
Led product strategy, UX/UI, content, and go-to-market across iOS, Android, and web, from onboarding architecture to brand voice. Ran Meta and LinkedIn campaigns end-to-end, delivering paid acquisition well ahead of cost benchmarks: Meta CPC of €0.88 against a €0.70–1.20 target, and CPM near €7.10 against a €6–14 target, LinkedIn's paid CPC of €2.52 sat inside its own €1.50–4.00 healthy range, reaching close to 290,000 unique people on a lean early-stage budget.
Drove an average website session time of 4:18, nearly 3x the 45–90 second benchmark for genuine engagement.
Took Zack from zero to a live app with 100+ installs on Google Play.

Chrome Extension (Manifest V3) + Figma Plugin · Claude Vision API · Vercel · Upstash Redis · Polar
Turn any image into a design token set. Colors, type, spacing, extracted in seconds.
Right-click any image, or upload one, Distill reads its colors, typographic mood, and spacing rhythm, and hands back a full token set.
Export as JSON, a Tailwind config, Style Dictionary, or a designed PDF sheet to share.
A companion Figma plugin (in progress) brings the same tokens straight into Figma variables, organized into a complete design system: color ramps, a type scale, spacing, radii, and elevation, plus a documentation canvas generated right on the canvas..
