Gristone

Freelance software development

Gristone is my one-person software company. You get a developer who also builds physical things – practical, detail-oriented, and allergic to overcomplicated solutions.

What I build

01 / 04

Web apps & sites

Fast, maintainable web applications, internal tools and websites – built to be easy to run long after launch.

  • Customer portals & dashboards
  • Booking, forms & admin tools
  • Static & serverless sites
02 / 04

Integrations & automation

Connect the systems you already pay for and remove the copy-paste work between them.

  • API integrations
  • Data pipelines & reports
  • Scheduled jobs & scripts
03 / 04

Hardware meets software

Sensors, microcontrollers and small devices talking to real software – from prototype to something you can rely on.

  • IoT prototypes
  • Monitoring & data logging
  • Custom control panels
04 / 04

Technical consulting

A second pair of eyes on architecture, tooling or a stuck project. Straight answers, no sales pitch.

  • Tech choices & planning
  • Code audits
