I’m Matthew J Downie, a software engineer with 15 years of experience delivering robust web applications and integrated systems. I specialize in leading cross-functional teams to design, develop, and maintain complex platforms.
Based in Round Rock, TX, I build scalable web apps on the LAMP stack, optimize databases, and implement infrastructure as code with Ansible, Vagrant, and AWS. I enjoy collaborating with product teams to translate requirements into clean, maintainable code and reliable deployments.
