Zdoor.design - Personal portfolio website

Hey! I am Ruslan Zdoor a product designer from Ukraine, Kyiv. I create user experiences that leave a lasting impression.

Product Design

Financial SaaS Tool (NDA)

Fintech

Problem

AI SaaS companies scale fast and burn faster. Without sector-specific benchmarks and real-time profitability modeling, finance becomes a lagging indicator instead of a strategic tool.

Solution

A purpose-built finance dashboard that connects P&L, unit economics, and retention into a single view — benchmarked against AI SaaS companies at the same ARR stage, with drill-downs that explain the why behind every number.

Results

• Designed a modular component system covering KPI cards, drilldown panels, trend charts, and benchmark bars.

• Structured information hierarchy so founders can move from summary → diagnosis → action in 3 clicks or fewer.

• Achieved 81% user retention week over week after launch.

• Got 72 NPS score from founding customer cohort.

Tower

Developer tool

SaaS

Problem

Developers running production pipelines had no visual layer that matched the complexity of what they were operating. Failures were buried in logs, environments required CLI expertise, and no existing tool gave teams a clear read on infrastructure health without significant manual effort.

Solution

I came in as the founding designer with nothing to inherit and built everything from zero: research, design system, core product flows, and a live marketing website — giving developers a single interface to monitor pipelines, diagnose failures, and manage environments without leaving the browser.

Results

• Designed and shipped an end-to-end platform, brand identity, and marketing website as the sole designer on the founding team

• 12% monthly bounce rate reduction by connecting Hotjar and updating high drop-off sections

• Grew private beta conversions by 30% in 3 months using scarcity and loss aversion principles

• Tower raised $6.4M — a team effort the design played its part in
