Behind The Code

Damian Demasi

I'm a frontend-focused software engineer based in Adelaide, Australia, with 5+ years building production software and 15+ years across engineering and technology.

I currently work as a Software Engineer at Aligent, where I build and maintain frontend systems for ecommerce platforms using React, Next.js, Magento/Adobe Commerce, BigCommerce, and modern development workflows. Before that, I spent three years at Amplify-Now building full-stack features for a SaaS product with React and Ruby on Rails.

I'm now moving deeper into AI engineering by building AI-enabled developer workflows, experimenting with agent systems, and writing about tools like Claude Code. My focus is practical AI: systems that help developers understand codebases faster, reduce repetitive work, and ship more reliable software.

Outside of work, I build side projects, write about AI tools like Claude Code and AI-assisted development, and experiment with agent systems, including a custom Claude Code-style agent harness. I'm also deepening my AI foundations through courses covering the OpenAI API, LLMOps, Hugging Face, prompt engineering, subagents, and agent skills.

I'm a Telecommunications Engineer with an MBA, originally from Argentina. After moving 12,000+ km to Australia, I rebuilt my career around software. That mix of engineering, business, migration, and software shapes how I think: understand complex systems, make them usable, and build tools that help people do better work.

Damian always goes above and beyond

Damian always goes above and beyond especially in terms of the documentation for the various investigations and solution designs he has done for our clients. They are always well formatted and presented professionally in a timely manner. They are written in a way that non-technical stakeholders can understand, and always provides context where necessary.

This level of work makes my job as an Analyst so much easier, and I appreciate the extra effort he puts in which impresses our stakeholders and keeps everyone engaged and on the same page.

He has adapted quickly to new tech stacks and started delivering value while still learning new technologies. This was impressive to see and exactly why I highly recommend Damian in any team, he will put in the effort to learn and adapt while delivering value early on in projects.

It's been great working with him and I look forward to working with him on future projects.

Damian Demasi is an easy recommendation

Damian Demasi is an easy recommendation. From the day he came on-board, he stood apart from the pack with an outstanding work ethic and attention to detail. Since then, he has become very strongly skilled in both React and Ruby on Rails.

What's more; he is professional, polite and fun to work with. He logically and methodically works through problems and is capable of wrapping his head around very complex systems. I can highly recommend Damian!
