About Me

ERP systems, from database to interface

I build ERP systems for a whole company to run on — designing the database, writing the business logic, and building the screens people use every day. Finance, procurement, loans: the work that has to be right. What I care about most is that it keeps running after release.

I worked in VB.NET and SQL Server on an in-house ERP platform, and I build my own products in Go, TypeScript, and Next.js.

ERP Systems

Production modules used across the company, every working day.

Databases

Schema design and query work on SQL Server, MySQL, and PostgreSQL.

Frontend

The screens on top — in ERP at work, and in React and Next.js outside it.

  • Jersey-number search and QR album links so players and fans find themselves in seconds
