What I'm looking for

I seek roles leading engineering teams to build scalable web and mobile products, emphasizing clean architecture, automation, and measurable user impact.

I am a Lead Full‑Stack Engineer with extensive experience building scalable web and mobile platforms using React, Node.js, AWS and containerization. I have led small dev teams, introduced coding standards and reusable UI components, and delivered features such as a real‑time Live Flight Tracker, SaaS marketplace modules, integrated messaging systems, and performant mobile apps that improved user ratings and traffic.

My work has driven measurable outcomes: a 40% reduction in downtime through CloudWatch monitoring, a 30% reduction in data‑transfer costs after migrating REST to GraphQL, and a 40% increase in daily user traffic via push notifications. I focus on clean architecture, automation (CI/CD), and cross‑platform solutions that prioritize performance, maintainability, and user experience.
