Message

At Client-Based (Ø-Obsolete), I build data-driven web applications with JavaScript, React, and Node.js. I’ve integrated REST APIs and relational databases, and replaced spreadsheet-driven workflows with web tools for small business clients.

I also assist with AWS deployments and support clients after delivery, making iterative improvements. I use Claude Code in my development work.

Before software development, I administered Microsoft Dynamics at Taisho Pharmaceutical and used SAP at Novartis and Grupo Pochteca. At Taisho, I led purchasing operations and achieved a 30% cost reduction through contract renegotiation, long-term supplier agreements, and procurement process optimisation.
