I've worked across startups and established companies, helping turn ideas into reliable, scalable products.
Earlier work
I started with electronics and microcontrollers, using C and assembly. Later, I built desktop software, mobile apps and business tools.
At NANKO, I rewrote access control and alarm software from assembly to C. Here are four more projects from that part of my career.
I built an app that showed a building in 3D and calculated its cost. Changing the building settings updated the model and the estimate. Engineers could use it to show customers their future building.
I developed screens and charts for a simulator system used at nuclear power plants. Engineers trained with the system. Engineers and scientists used the charts to view reactor parameters and analyse simulation results.
In the early 2000s, a partner and I built and sold a CHM reader for pocket computers (PDAs). It let people read technical books and software documentation offline, on a small device.
Equipment. I connected security equipment with smart home systems. When devices failed to communicate in a large DSC installation, I investigated the problem and worked with the manufacturer through several rounds of fixes.
Business software. While running the company, I also wrote PHP and JavaScript. I changed SugarCRM modules, forms and fields to fit our sales process, client documents and reports. I connected it with website enquiries and email, and worked on accounting integrations.
