MariaDB (April 2026 - present) - Senior frontend developer

I joined MariaDB after it acquired GridGain. I work on MariaDB Enterprise Manager, MariaDB Cloud and GridGain Control Center.

Highlights

• Shortly after joining, designed and delivered the integration between MariaDB Enterprise Manager and GridGain Control Center. I owned the feature design and the UI design, and built most of the implementation with coding agents, across a frontend and two backends that were new to me.

GridGain (2017 - March 2026) - Senior frontend developer

GridGain Control Center/Nebula

GridGain's platform for provisioning, managing and monitoring GridGain and Apache Ignite clusters.

Highlights

• From mid-2025, drove the team's adoption of coding agents and invested heavily in making the project agent-ready: faster feedback loops, agent instructions and 20 skills, and integrations with Jira and TeamCity. Used agents to modernize the codebase through refactorings too large to be realistic by hand.
• Architected the Angular application from scratch and evolved it over the years, with 1,100+ pull requests of my own. New developers ramped up on it with little trouble.
• Designed a Grafana-style framework for customizable monitoring dashboards, where new widgets plug in through well-defined interfaces. Wrote several of the widgets myself: charts, grids and real-time data views.
• Built the networking layer for a custom RPC protocol over WebSockets and STOMP. To go with it, built a Node.js tool that mocks the backend at the protocol level, for UI development and E2E tests. Its simple API hides the protocol details from other developers.
• Shaped features beyond the frontend. Helped design most of them, so that the data presentation, the mix of REST, STOMP and RPC, and the backend endpoints fit what the UI could do. Proposed a generic way to track long-running cluster operations, which the backend team later implemented.
• Kept unit and E2E test coverage high, and wrote many of the tests myself.
• Delivered features on time in a cross-functional team. When needed, managed the frontend team: turned vague feature requests from management into Jira epics and tasks, and planned the work.
• Reviewed a lot of code, with a focus on requirements, design, maintainability and test coverage. Left formatting to Prettier, which I introduced. Colleagues rated my reviews highly.

Apache Ignite Web Console

The previous generation of Apache Ignite and GridGain monitoring and management, later replaced by GridGain Control Center/Nebula.

Highlights

• Took over a codebase whose structure didn't scale and was hard to maintain. Re-architected it around components, introduced E2E testing and RxJS for real-time data, and helped teammates learn the new tools.

Saritasa (2013 - 2017) - Frontend developer

A small consulting company with offices in the USA, Russia and Vietnam, where I learned a lot.

Highlights

• Architected the frontend of my last project: a trading app, rewritten from a Java desktop app to web (Angular.js) and mobile (Ionic, Apache Cordova). Along the way, learned to handle real-time data, build highly customizable UIs, share one codebase across web and mobile, and profile performance with Chrome DevTools. These lessons paid off later at GridGain.
• Built many small and medium-sized Angular.js apps for web and mobile (Apache Cordova).
