Kyiv Metropolitan Area Ukraine
Summary
👤
SeniorMark Tanashchuk is a Senior Software Engineer with 7+ years building full-stack, distributed systems for healthcare, e-commerce, and government that scale to 100,000+ users. He blends modern front-end frameworks (SvelteKit, Vue, React) with back-end Rust and Node.js expertise to deliver performant, resilient products and has repeatedly improved metrics like signup rates and platform usage. Past roles include accelerating search and deployments—cutting response times from seconds to 40ms and reducing releases from hours to minutes—while saving significant hardware and operational costs. He favors preventive engineering and collaborative processes to reduce unknowns, and prefers autonomy over time-tracking-heavy environments. Based in Kyiv, Mark brings a pragmatic, analytical approach to optimizing plans and architectures, often pushing migrations (e.g., to SvelteKit/TypeScript) that materially boost user engagement.
