About me

Grigor Yankov

Senior React & React Native Engineer | AI-Forward Development

Sofia, Bulgaria

Professional summary

Senior engineer building scalable React & React Native products — from enterprise mobile migrations to monorepos and AI-forward delivery with Cursor and Claude Code, always grounded in DDD and solid architecture. Currently Senior React Native Developer at Phoenix, and I teach at STEP IT Academy on the side.

Career journey

From first shipped MVPs to senior mobile engineering at Phoenix

  1. Web Developer

    MOXX Advertising · Sofia, Bulgaria / Remote

    • Engineered and launched an internal React Native MVP dashboard for tracking website health metrics and marketing KPIs on the go.
    • Built and maintained web applications with interactive frontends, custom WordPress components, and Puppeteer automation workflows.

    That first shipping rhythm — from MVP to production — set the foundation for everything that followed: owning the full stack of a feature, not just a screen.

  2. Part-time · Ongoing

    Lecturer in Software Development

    STEP IT Academy · Sofia, Bulgaria

    • Develop and deliver curricula focused on React.js, JavaScript, ES6+, AJAX, HTML, and CSS.
    • Mentor students in classroom and online settings, preparing them for modern engineering roles.
    • Evaluate progress with constructive feedback and targeted technical support.

    Teaching forced me to distill complex ideas into clarity — a skill that later shaped internal tech-talks, code reviews, and team standards in enterprise environments.

  3. Promoted to Mid-Level within 8 months

    Mid / React Native Developer

    BayBridgeDigital | Salesforce Summit Partner · Sofia, Bulgaria / Hybrid

    • Core developer on Bayes Retail — a premium Salesforce AppExchange omni-channel commerce clienteling solution for Fast Retailing (Princess Tam Tam, Comptoir des Cotonniers).
    • Replaced legacy lists with @shopify/flash-list, rewrote critical UI with react-native-reanimated, and architected an aggressive data-caching layer.
    • Authored custom Native Modules bridging system-level capabilities; managed CI/CD and App Store / Play Store delivery for multi-tenant apps.
    • Established internal tech-talks and knowledge-sharing; earned written recommendations from VP, Product Manager, and Team Lead.

    Enterprise retail at global scale taught me performance engineering under pressure — the bridge to my next challenge: migrating real users off legacy native codebases.

  4. Senior Software Engineer

    Inoreader · Bulgaria / Remote

    • Spearheaded migration of legacy Objective-C (iOS) and Java (Android) apps into a unified high-performance React Native codebase.
    • Built custom Native Modules for background syncing and massive RSS stream parsing with platform performance parity.
    • Engineered secure session migration via native keychain storage — users kept authenticated sessions without re-login.
    • Created a cross-platform Design System from scratch; owned end-to-end App Store and Google Play releases.
    • Leveraged AI coding agents (Cursor, Claude Code) for velocity while maintaining structural integrity and code validation.

    Migrating an entire product across a technology boundary — without losing a single user session — is the kind of challenge I now bring to Phoenix as a senior engineer.

  5. New · Started Jul 2026

    Senior React Native Developer

    Phoenix · Sofia, Bulgaria

    • Senior engineer on Phoenix's React Native mobile products — owning architecture, performance, and delivery.
    • Bringing AI-forward workflows (Claude Code, Cursor) and DDD-grounded architecture into day-to-day product engineering.
