I build systems from napkin concept to information architecture to production — from design in Figma to implementation in code and support in a real product. Specialize in complex product interfaces with large amounts of data and AI interfaces, grounded in continuous research with end users in the field. Grew up from typography, linguistics, and electronics, so I think about interfaces as systems that balance between user needs, business requirements, and practical aesthetics. Strongest where design is an engineering problem: typography, data, interaction — not a decorative layer that adorns the interface. SKILLS Product Design (10+ years), Figma (Advanced), Mobile & Web Design, Cross-Platform UX, Human-AI Interaction, User Research, Prototyping, Design Systems, Data-Driven Design, Internet of Things, Industrial SaaS, Data Visualization, HTML/CSS/JS, React, Pretext.JS, TypeScript, C++, Python. EXPERIENCE Luxoft (Halliburton) — Senior Design Engineer April 2025 — December 2025 | Remote Designed real-time interfaces for industrial IoT monitoring (oil & gas industry), leading solutions from concept to developer handoff. • Ran biweekly research with control-room managers and field operators: crews on the wellsite, where a rugged iPad is the safety-critical interface. Access to these busy, non-technical users was rare, which made every session count. • Research showed that a dense, fixed set of readings locked operators in. Replaced it with a short list of key metrics from which each operator picks the ones critical to their job. • Created real-time data visualization components for mission-critical sensor data streams. Used by operators both in control rooms and on location in harsh conditions. • Designed offline-first interaction patterns for field conditions with unstable or absent connectivity. Hivecell — Senior Design Engineer / Product Designer June 2021 — December 2024 | Kyiv — Lviv — Remote Led product design in a multi-platform edge computing ecosystem for managing a fleet of server clusters: from configuring individual servers through UI to connecting via SSH and ordering additional capacity in a single web application. • Designed interface architecture for IDE, cluster orchestration, developer portal, and AR onboarding for users of all levels of technical proficiency. • Built a micro-interaction system: state transitions, loading patterns, and feedback choreography. • Ran biweekly research with infrastructure managers and the on-site staff who installed edge servers at lifecell (Ukrainian mobile operator) sites, down to cleaning managers. Setup had to be that simple. Findings drove the IA and workflow changes behind the results below. • Achieved a 30% reduction in engineer inquiries, 50% reduction in support inquiries, and reduced time to complete key tasks by 40% through optimization of UX and IA. Artkai — Lead Designer / Design Technologist June 2019 — June 2021 | Kyiv Developed data-informed design practice in fintech, e-commerce, and enterprise projects for clients, balancing user needs and business goals. • Rebuilt the company's internal design infrastructure and launched systematic A/B testing programs for optimizing client products. • Together with three lead designers and the co-owner of the company, created a grading and promotion system for the design department. • Mentored three junior designers, conducted regular design reviews and knowledge-sharing sessions. SoftServe — Middle Experience Designer March 2017 — June 2019 | Kyiv — Lviv — Remote — Wrocław Delivered complex data-intensive web and mobile interfaces for enterprise and government clients. • Created accessibility-compliant components and scalable data-dense form systems reused by the design department. • Conducted workshops on typography, design systems, micro-interactions, and design of non-visual interfaces (audio, haptic). Advertising agencies — UI/UX Designer & Front-end Developer 2012 — 2017 | Kyiv Led end-to-end product design together with front-end coding. Delivered cross-platform solutions for Coca-Cola, Pernod Ricard, and Danone.
