Roslan Lbzo

Senior Full-Stack Engineer

I lead frontend architecture for complex, high-traffic React and Next.js products — from system design and tech decisions through to delivery. I've built and scaled platforms serving millions of users, and I bring the kind of technical ownership that keeps engineering teams moving without creating chaos.

What I Do

Working across the full stack with a focus on quality and practical outcomes

Front-end Engineering

  • Build scalable interfaces with Next.js, React, and TypeScript
  • Component-based architecture and design systems
  • Performance and accessibility built in from the start

Full-Stack Delivery

  • End-to-end feature delivery across frontend and backend
  • API integrations, OAuth flows, and data handling
  • Comfortable working across the full stack and owning implementation

Infrastructure & Tooling

  • Docker-based local development and CI/CD workflows
  • Cloud hosting on Azure with deployment pipeline experience
  • Developer experience and build tooling improvements
