Hi, I'm Eugene—a full-stack engineer who enjoys the awkward middle between a promising idea and a system people can trust. I have been building production software since 2011, from commerce and authentication flows to cloud platforms, AI agents and WebGL experiments. I am happiest when the problem is still a little messy: shape the first useful version, make the trade-offs visible, ship it, then harden what survives contact with real users. My current toolkit is centered on Svelte, React, TypeScript, Kubernetes and AWS/GCP, with a growing amount of security, agentic systems and Three.js work.

14+ years building production web systems across frontend, backend, infrastructure and integrations.
I work across the full delivery loop: discovery, scoping, architecture, implementation, rollout and the unglamorous fixes after launch.
Current rabbit holes: security and passkeys, Kubernetes, AI agent reliability, tool execution, observability and real-time graphics.
A few recent examples where the job went beyond writing a component: partner launches, identity and security flows, commerce delivery and agent systems that need to behave well outside a demo.
Helped deliver Yubico’s side of the public OpenAI Advanced Account Security / YubiKey bundle in spring 2026. (public launch)
Impact: Shipped partner API integration, a custom product page, checkout flow and authorization handoff across Yubico ecommerce and account systems.
I work directly with Yubico’s authentication and security teams on an organization-wide authorization flow for future products.
Impact: Helped scope service details and integrate the flow across product surfaces, ecommerce, account systems and multiple internal teams.
Evolved a long-running Telegram bot from local chat utilities into a production-like LLM-powered agent system.
Impact: Built async workers, reply gating, model routing and fallbacks, tool execution, memory, metrics and feedback loops around real group-chat behavior.
Delivered customer-facing third-party commerce work across Yubico and Daniel Wellington.
Impact: Supported local payment methods, regional store launches, campaign delivery and Black Friday readiness under production launch constraints.
Not just the stack and a screenshot: what I owned, how each system works and which trade-offs survived contact with real users.
