Let’s build something sharp, scalable, and actually useful.

I'm a Software & Business Developer specializing in mid to large eCommerce companies. When an eCommerce business grows beyond the startup phase, the quick, short-term solutions that once worked often start breaking down. That’s when infrastructure becomes essential — and that’s where I come in. I help growing teams build that next layer of structure by implementing real, scalable systems. My focus is on making operations more efficient, connected, and ready for scale. Some examples of what I do: Evaluating and implementing Order Management Systems (OMS) Automating internal processes that drain time and resources Building custom reporting tools for finance and accounting teams Creating integrations to connect isolated systems and platforms To get the most value from my work, I only take on projects where there's already an OMS/ERP in place, or a clear intention to implement one. I’ve worked with a range of platforms, including: Cin7, CommerceHub, Linnworks, Odoo, Sellercloud, Skubana, SKUvault, and Zentail.
