About

Owning the whole lifecycle

I design and deliver end-to-end web applications across both the PHP/Laravel and JavaScript (React, Vue, Node) ecosystems.

My work covers RESTful APIs, relational and NoSQL schema design, and production-grade responsive interfaces. I have delivered ERP and CRM systems, e-commerce platforms and AI-powered automation tools, for clients through freelance work and in full-time teams.

I take a project from requirements and architecture through to deployment on AWS with CI/CD, working alongside product, design and DevOps.
