Rafalsky - Overview

๐Ÿ‘จโ€๐Ÿ’ป Senior Full-Stack Engineer

I design and build production-grade web applications with a strong focus on scalability, performance, and long-term maintainability.
My work sits at the intersection of frontend architecture, analytics engineering, and developer tooling.


๐Ÿš€ Core Expertise

  • JavaScript / TypeScript โ€“ advanced, strongly typed, production-oriented
  • Frontend Architecture โ€“ scalable SPA/MPA/SSR systems
  • SDK & Platform Development โ€“ shared libraries, helpers, internal tooling
  • Analytics & Tracking Engineering โ€“ event-driven data design

๐Ÿง  Areas of Focus

Frontend Engineering

  • Vue.js (Vue 2 & Vue 3), Nuxt 3
  • State management, reactivity models, performance tuning
  • SSR, hydration strategies, rendering trade-offs
  • Component libraries and design systems

Backend & Tooling

  • Node.js (APIs, backend-for-frontend, CLI tools)
  • PHP (modern PHP & legacy systems)
  • Symfony (service architecture, integrations)
  • Schema-driven development and validation

Analytics & Data Layer

  • Snowplow (event schemas, Iglu, Micro, governance)
  • Google Analytics / GA4
  • Google Tag Manager (client-side & server-side)
  • Data layer design, telemetry, contract-based tracking
  • CI validation of analytics implementations

๐Ÿงช Testing & Quality

  • Unit testing and integration testing
  • End-to-end testing (Cypress, Playwright)
  • BDD and contract testing
  • CI-driven quality gates
  • Performance monitoring and debugging

๐Ÿ—๏ธ Engineering Principles

  • Clarity over cleverness
  • Strong contracts and schema discipline
  • Scalability by design, not by accident
  • Observability as a first-class concern
  • Codebases built to survive years, not sprints

๐Ÿ” Current Technical Interests

  • Advanced frontend architectures in large-scale systems
  • Analytics reliability and first-party data resilience
  • Developer experience and automation
  • Server-side tracking and event governance

Focused on building reliable systems, clean abstractions, and software that ages well.
