Junior UI/UX Designer

Profile

Designer who also codes. I've shipped a real Android app end-to-end, so my design decisions account for
what's actually buildable, not just what looks good in Figma. Full-cycle experience: user research,
information architecture, wireframing, hi-fi prototyping, usability testing, and iterating until it works.
Looking for a product team where design is treated as a craft, not decoration.

Design Skills

Core

Wireframing (lo-fi/hi-fi), Interactive Prototyping, Usability Testing, Responsive Design, Design Systems

Tools

Figma (primary), Android Studio (for implementation context and feasibility checks)

Process

User research, information architecture, iterative design, accessibility auditing

Technical

Kotlin, Java, Git/GitHub: enables smooth developer handoff and realistic constraints

Languages

Ukrainian (native), French (A2, conversational basics, self-taught), English (A1, actively improving)

Experience

UI/UX Designer Intern · IT STEP Academy

May – Jun 2025

• Designed Musica, a cross-platform audio-streaming concept (Web, Android, iOS): owned the full
cycle from user research through final prototype delivery.

• Conducted target-audience interviews and synthesized findings into user personas and an
information architecture map before touching any visual design.

• Built low-fidelity wireframes, validated structure with stakeholders, then produced dark-themed
high-fidelity prototypes in Figma for desktop and mobile breakpoints.

• Ran moderated usability testing sessions with 5+ participants, identified navigation friction and
visual hierarchy issues, iterated through 3 design rounds to resolve them.

Android Developer Intern · Chat Veterana (NGO)

Apr – May 2026

• Designed and then implemented DualSubPlayer's interface and interaction flow in native Android,
making every UI decision with real technical constraints (media playback timing, lifecycle states) in
mind.

• Experienced firsthand what happens when a design doesn't account for edge cases: buffering
states, subtitle sync failures, orientation changes. Now I design for those upfront.

• Presented the finished product's design rationale and functionality to an evaluation commission.

Projects

Musica · Figma, UI/UX, Responsive Design

Dark-themed interactive design concept for an audio-streaming platform. Adapted across desktop and
mobile. Full process documented: research → personas → IA → wireframes → hi-fi → testing → iteration.

DualSubPlayer · Figma, Android Studio, Kotlin

Designed and shipped a language-learning app interface from concept through to a working Android build.
Proof that I don't just hand off mockups: I can verify implementation matches intent.
