01SELECTED PROOF

Evidence before adjectives.

Four projects, four different constraints. Each one shows how I translate product requirements into usable interfaces.

01 / PRODUCT BUILDCLIMBLENSEARLY ACCESS

Turning one climbing video into one useful next move.

Product direction / responsive pre-launch experience

ClimbLens is an AI video coach for climbers. I shaped the web experience around a short promise: record an attempt, receive one focused cue, and test it while the route is still fresh.

  1. 01 / Problem

    Make an ambitious AI product feel immediate

    Movement analysis can quickly become abstract. Climbers needed to understand the value before seeing a finished mobile app or a dense analytics dashboard.

  2. 02 / Decision

    Build the story around one repeatable loop

    The interface moves from camera setup to analysis and one next-attempt cue, supported by product screens, real climbing imagery, and plain-language feedback.

  3. 03 / Result

    A credible route from idea to early access

    The responsive launch site connects the product narrative, audience use cases, waitlist, consent, and legal surfaces into one coherent pre-launch experience.

02 / CLIENT BUILDLOS LASEROSCMS + RESERVATIONS

A business website the owner can actually operate.

Hover to scan the full page / live client website

Los Laseros needed more than a promotional landing page. The site combines the venue story, offer, gallery, pricing, map, and a practical reservation flow.

  1. 01 / Problem

    Content changes after launch

    A static build would leave everyday updates — especially imagery and offer details — dependent on a developer.

  2. 02 / Decision

    Pair the public page with a CMS

    I connected the Next.js experience to Payload CMS and shaped the content structure around real admin tasks.

  3. 03 / Result

    One coherent path from interest to booking

    Visitors can understand the venue and send a reservation request, while the business can manage core content through its own dashboard.

03 / CONCEPT BUILDTAVOLUNABRAND + MENU

Making a fictional restaurant feel ready for its first table.

Fictional restaurant concept / complete responsive experience

Tavoluna is a fictional Italian pizzeria created as a portfolio concept. I turned a simple restaurant brief into a warm, coherent experience spanning story, atmosphere, menu, reviews, and visit information.

  1. 01 / Problem

    Create trust without an existing brand

    The concept needed to feel specific and established even without a real location, customer history, or inherited visual identity.

  2. 02 / Decision

    Let atmosphere lead the information

    Warm food photography, editorial typography, and a clear story-to-menu rhythm make the experience emotional first and practical immediately after.

  3. 03 / Result

    A complete restaurant journey on any screen

    Visitors can move naturally from first impression to dishes, social proof, location details, and a direct reservation action.

04 / HACKATHONASTROCOLONY24 HOURS

Making a simulated Mars colony readable at a glance.

AstroColony resource dashboard with water, energy and oxygen metrics
Resource dashboard / SpaceShield Hackathon 2025

Built with a team during the 24-hour SpaceShield Hackathon, AstroColony turns environmental simulation data into a product people can explore and act on.

  1. 01 / Problem

    Dense simulation data under time pressure

    Water, oxygen, energy, weather, and map state all needed a clear hierarchy — with very little time to iterate.

  2. 02 / Decision

    Prioritize status, trend, then detail

    The frontend organizes resource health into scannable cards and connects the dashboard to an interactive colony map.

  3. 03 / Result

    A working cross-stack prototype in one day

    The team delivered live resource views, structure placement, and scheduled environmental updates backed by a REST architecture.

02CAPABILITY / EVIDENCE

What I can do — and where I proved it.

A technology list says very little on its own. This is the same toolkit tied to concrete product situations.

04 / ABOUTTHE PERSON BEHIND THE UI

Curious about the seam between product thinking and implementation.

I am a software developer from Sandomierz, Poland, focused on frontend and growing toward full-stack product work. I like turning ambiguous requirements into a sequence of clear decisions: what matters, what changes, and what the user needs to see next.

My interests sit where web development, AI agents, automation, and automotive technology meet. I am looking for a team where I can keep learning while contributing to real interfaces from day one.
