The path so far

From supply chain and accounts to software and growth

I started my career in 2019 at Universal Gas Installations, moving from data entry to assistant accountant to office manager. I handled payables, receivables and payroll, inventory and stock management, supplier coordination, and ISO 9001 quality and ISO 45001 health and safety documentation.

In 2023 I moved into software at BitAffix, designing ERP modules for sales, purchasing, inventory and HR. In 2025 I joined Aun Digital, where I build and maintain client platforms with Laravel, Inertia.js and React, alongside technical SEO and performance work.

Business-first engineering

Why this background makes me a better builder

ERP and business software exists to run purchasing, stock, payroll and compliance. I spent years doing those jobs by hand. When I design an inventory module or approval workflow, I understand where stock gets miscounted, where approvals stall and what reporting needs to show. The same business thinking shapes growth work: start with how customers decide, then build and measure each step.
