Denys Galkin

Senior Front-end Engineer focused on React, Angular, React Native, Expo, and Capacitor, with 10+ years across web and cross-platform mobile products.

I turn ambiguous product requirements into reliable web and mobile delivery: from system design, API contracts, and implementation planning to staged rollouts, monitoring, and production releases.

What I work with

• React, React Native, Expo/EAS, TypeScript, Angular, Capacitor, and Apache Cordova modernization
• Cross-platform architecture, WebView bridges, deep links, native integrations, and file workflows
• GitHub Actions, semantic versioning, release automation, feature flags, and Sentry
• API migrations, frontend platform improvements, mentoring, and cross-team delivery
• Claude Code, Codex, local LLM experiments, and AI-assisted engineering workflows

Open source

• Sentry PR #22300: allow consent-gated applications to stop Replay without force-flushing captured data
• Sentry issue #22220: proposed a consent-safe Replay.stop() API for GDPR-sensitive applications
• Sentry issue #22261: proposed suppressing browser session capture before analytics consent

Selected work

• Video to Text Converter: local multilingual transcription for video and audio using Whisper
• Capacitor Installer Source: Capacitor plugin for identifying an Android application's installer source
• Capacitor SEON Plugin: Capacitor integration for SEON device fingerprinting
• Resume: experience, skills, and contact details

Currently exploring

Production-ready AI-assisted development, local coding agents, and repeatable ways to bring LLMs into engineering workflows without compromising review quality or system understanding.
