Selected work
Platform work across real production systems
The main work I want to be known for: shared account platforms, cross-product UI architecture, design systems, and developer tooling used by product teams.
Technical leadership and platform ownership for the Business Accounts SDK used by approximately 25 Xsolla account apps, covering shared packages, thin-host migrations, Module Federation, release trains, analytics, observability, and cross-platform design systems.
Overview
Key technical leader and owner of the Business Accounts platform SDK used by approximately 25 account apps across xsolla.com/accounts, focused on architecture direction, migrations, shared platform capabilities, and product-team enablement.
Key Responsibilities
- Led the Business Accounts SDK monorepo using pnpm and Turborepo, publishing reusable packages for shell infrastructure, APIs, state management, UI, pages, localization, and BFF across the suite
- Drove the thin-host model and skeleton template by moving shared routing, Module Federation hosting, polyfills, and authentication bootstrapping into published SDK packages, then rolling that model out across live Business Account applications
- Built the Business Accounts CLI, MCP server, and AI agent kits so humans and coding agents can scaffold, validate, migrate, and upgrade hosts without forking platform code
- Owned package versioning, GitLab Package Registry publishing, merge-request preview versions, and release-train upgrades with adoption checks so a package bump includes host wiring rather than only a version number
- Designed Module Federation host and remote integration across React 16 hosts and React 18 remotes, including runtime remote loading and shared dependency strategies
- Built shared product analytics on Xsolla Metrika, including an event catalogue, sidebar instrumentation, and host adoption rules for consistent product telemetry
- Co-led the development and migration of a cross-platform design system for React and React Native with multi-theme support across Publisher Account and Business Accounts
- Shipped shared platform product surfaces used across accounts, including projects list and switcher, settings, members, agreements, payouts, login, and legal consent
- Implemented frontend and backend observability using Datadog RUM and OpenTelemetry, improving error visibility and correlating application behaviour, logs, and performance traces
- Mentored engineers and contributed to internal technical education through Xsolla School
