Hi, I'm Eugene, a full-stack engineer based in Stockholm. I've been building software professionally since 2011 and got my systems engineering degree from BSUIR in 2013. I like math, algorithms, good UX and other boring things. Most of my work has been full-stack: Node and Java on the backend, React and Svelte on the frontend, running on Kubernetes and AWS/GCP. These days I spend a lot of time on security and passkeys, AI agents and real-time graphics with WebGL/WebGPU. I enjoy taking a messy product or platform problem, building the first version that works, and turning it into something a team can run and improve.
Download CV14+ years building production web systems across frontend, backend, infrastructure and integrations.
End-to-end delivery: scoping, architecture, implementation, rollout and support after launch.
Currently into security and passkeys, Kubernetes, AI agents, 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)
Delivered: 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.
Delivered: 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.
Delivered: 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.
Delivered: Supported local payment methods, regional store launches, campaign delivery and Black Friday readiness under production launch constraints.
What I built and owned in each project, how it works and the trade-offs behind it.

A souls-lite adventure played with one thumb. A WebGPU renderer and a Phaser renderer draw the same game state, so the style switches mid-fight.
