Senior Frontend Engineer

I architect Playmaker, a sports marketing platform, in an Nx and Lerna monorepo with shared libraries and isolated application modules that enable parallel development streams.

I built a drag-and-drop page editor with craft.js and delivered Claude API features including streaming chat and PDF/image OCR with Zod-validated structured outputs. I also own frontend state, type-safe navigation, internationalization, shared Storybook components, API integration, and agent-assisted delivery workflows with reviewed code changes.

I led a frontend rebuild of QA tooling for an Estonian game studio, redesigning the administration panel, adding chart-based metrics dashboards, and resolving state-management issues that caused inconsistent UI data.

I also built frontend architecture for a Monaco real-estate platform and contributed to an edtech platform for US schools. My work covered design review, maintainable UI implementation, third-party API integrations, and deployment using React, TypeScript, and Next.js.

I built a single-page application for real-time monitoring and management of router operations for a US client. The interface was designed to remain readable and reliable under frequent live data updates.

I implemented Redux state management and data flows with strict TypeScript typing, improving maintainability and consistency across the application.

I delivered web and React Native mobile applications across the full stack, from user interface implementation through API development and the database layer. I used Node.js, Express, REST, GraphQL, PostgreSQL, and TypeORM.

I built custom real-time chat functionality, dynamic data tables, and a Google Maps integration in a Docker-based development environment.

I modernized the interface of a Drupal-based cloud-storage web platform by introducing React components and improving frontend performance.

I worked in an Agile team using JavaScript, HTML, and CSS to deliver maintainable interface improvements.

I independently build and operate an open-source cloud storage product comprising a React, TypeScript, and Ionic application, a Next.js public site, serverless API functions, and an Nx monorepo. The product supports multiple storage backends through a shared upload, listing, and deletion contract.

I implemented semantic file search using Claude, Voyage embeddings, PostgreSQL, and pgvector; Stripe subscriptions with secure webhook handling; and comprehensive quality and security controls. The project includes more than 1,700 unit tests, Playwright end-to-end tests, CI bundle budgets, Sentry monitoring, row-level security, and performance work that reduced mobile LCP from over seven seconds to under four seconds.
