What I'm looking for

I’m looking for a team where I can own frontend delivery end-to-end—building scalable Angular/React/Next.js UIs, optimizing performance, and shipping with strong testing and mentorship—especially on SaaS/CRM and AI-powered products.

I’m a Senior Frontend Engineer with 5 years of commercial experience delivering scalable web applications across Angular, React, and Next.js (TypeScript). I’ve built complex UI and frontend architecture for SaaS, CRM, marketing platforms, and AI-powered products, including large-scale Angular systems and 25+ apps in a shared monorepo.

I bring strong hands-on depth in REST APIs, WebSockets, and state management with NGXS/NgRx, with a clear focus on frontend performance. I also own quality end-to-end through unit, integration, and E2E testing using Jest, Jasmine/Karma, Cypress, and Playwright.

I drive full delivery ownership—from planning and design to implementation and production—plus code reviews, technical interviews, mentoring, and delivery coordination during leadership transitions. I’m comfortable aligning stakeholders, unblocking developers, and keeping production work moving.

Among my standout contributions: implementing SSE streaming UI for AI tools with real-time “typewriter-style” output, developing and reusing shared UI libraries across multiple apps, and embedding React components into Webflow-based production marketing pages. I’ve also led Angular modernization (v14–v20) in production, introducing standalone/control flow and signals refactors, and integrated analytics and monitoring (Mixpanel, Intercom, Sentry, Google Analytics, GrowthBook) for product visibility.
