I’m Dawid Tomkalski, a software architect who still writes the code.

I’ve built software for 18 years. The last eight were at Homhero, where I started as a senior software engineer and became its solutions architect. I designed its serverless platform for holiday-rental managers across Australia and New Zealand and shaped Hompay, its payments stack. My last project there was Homtrust, a multi-tenant trust accounting platform that Australian agencies use to hold client money, where I led the architecture from 2023 to 2026.

I started DaTom in 2014 and ran it alongside those roles, taking on architecture, integration and AI workflow projects for clients. Since leaving Homhero in 2026 it has been my full-time work. When you hire DaTom, you work with me: no account managers, no hand-offs.

Before Homhero I worked in the UK from 2008 on intranets, learning management systems and financial web services, then in Australia on lending, payroll, telecoms and insurance products. I co-founded a startup, introduced Scrum and test-driven development to several teams, and mentored a lot of engineers along the way.

I care about systems that stay correct when something fails, that are secure from the start, and that the team who inherits them can run without me. I explain trade-offs in plain language, so the people paying for them can decide.
