Experience

Lead Front End: Motive Spend Management (2022–2024)

https://gomotive.com/products/spend-management/
I led front-end engineering (2022–2024) for Motive's Spend Management platform, a fintech solution for a $3B+ company serving 120,000+ businesses and 1M+ drivers. Leading a team of 6, I architected the "Vehicle-based Cards" and "Spend Profiles" features, which are critical to Motive's $500M+ ARR. I built automated fraud detection and metadata workflows that significantly reduced client losses. My work focused on high-scale security and Datadog observability for a live platform heading toward an IPO. Industry testimonials and public product endorsements are available on professional networks.

Front-end Developer and UI Designer

https://www.qubitbyqubit.org/
In 2020, I designed and built the landing pages for "Qubit by Qubit," a global quantum education initiative in partnership with IBM and Google. The platform now serves 30,000+ students across 130 countries. I built the specialized course enrollment system that drove 500+ signups in month one and improved SEO visibility by 50%. My work focused on WCAG accessibility, performance optimization, and conversion-driven UI/UX, directly contributing to a 15% increase in student enrollment. Public testimonials and verified results from 2020 onwards are available on professional networks.

Full-stack Lead: Virtual Events and Speed Networking Platform (2020–2022)

I was a founding full-stack developer at Westa, a Moscow-based virtual events startup. I engineered the platform's core "Speed Networking" engine using React and GraphQL, enabling AI-driven matchmaking for live video calls. I also shipped the Polls feature from concept to launch in just 45 days. My technical contributions helped drive a 50% increase in regional users through localized support (Ukrainian/Russian) and automated engagement services. Note: Platform operations were suspended in 2022 due to regional conflict; architecture details and code samples are available upon request.
