About

Professional summary

I am a Senior Frontend Developer with over eight years of experience building enterprise, e-commerce, and digital marketing solutions. I specialize in creating scalable, responsive, and high-performing web applications using Angular, React, Next.js, TypeScript, and JavaScript.

I have delivered business-critical frontend solutions for organizations including Willis Towers Watson and Accenture. My work includes developing reusable component architectures, integrating REST APIs, modernizing legacy JavaScript applications, and improving application reliability and maintainability.

I have strong cloud and DevOps experience, including AWS serverless development and automated deployment pipelines with Azure DevOps CI/CD. I use Git-based workflows, participate in code reviews, and work effectively in Agile and Scrum teams alongside product owners, designers, QA engineers, and backend developers.

I also have hands-on experience building and customizing WordPress, Shopify, and WooCommerce solutions for local and international clients. I focus on responsive, mobile-first development, cross-browser compatibility, performance optimization, and translating client requirements into practical technical solutions.

I leverage AI-assisted development tools such as ChatGPT and GitHub Copilot to accelerate debugging, testing, documentation, and delivery while maintaining engineering quality. I enjoy mentoring junior developers, contributing to frontend architecture decisions, and continuously improving development processes.
