IONT tech · 2023–2024

IONT platform.

A public EV-charging network from an empty repository to launch: the driver app, a ČSOB-certified payment gateway and an admin panel running on the charger’s own Raspberry Pi.

Role: Fullstack Engineer
Timeline: Aug 2023 – Sep 2024
Sector: Clean Energy · Payments

Launch: 5 months; Empty repo to public launch
Payments: ČSOB; Certified bank gateway
Hardware: Raspberry Pi; Admin panel on the charger

The challenge

IONT tech needed three products that work as one: a public app where drivers find a charger and pay, a payment gateway certified by ČSOB that talks to the charger in real time, and an admin panel that runs offline inside each unit. As the only fullstack engineer, working with the firmware team, I took it from an empty repository to public launch.

What I owned

Public charging app
SvelteKit app where drivers find a charger, authorise it and follow the session live, designed mobile-first.
Payment gateway
Certified ČSOB integration with real-time charger communication, built with the firmware team to meet financial compliance requirements.
On-device admin panel
Offline-first panel on the charger’s Raspberry Pi for configuration and diagnostics, with a signed auto-update system for the fleet.
Infrastructure and delivery
Designed and deployed the whole environment as Docker Swarm microservices, with CI/CD pipelines and Linux server administration.
