Krzysztof Jagiello
Senior software engineer in Uppsala, Sweden
I work on real-time systems, developer tooling, and home-automation projects that tend to get out of hand. Lately that means everything from servers to custom circuit boards.
Work
Amara · day job
A tablet made for older adults, and an app for their families. I work across the whole stack: an AI agent built for older adults, the Python backend, the Flutter app, and the hardware around the tablet, from firmware in Rust to electronics and enclosure design.
Aivi · side project
An HTTP API for iOS Live Activities and widgets. Anything that can send a request, like Home Assistant, a 3D printer or a CI pipeline, can put live updates on the Lock Screen, Apple Watch and CarPlay.
Open source · on GitHub
A bunch of projects in various states of finish, from diagram tools and OpenTelemetry instrumentation to LED matrix drivers.
Previously
Billogram · 2021–2026
Product features, integrations with banks across Europe, and the shared infrastructure and tooling the other teams built on.
5 Monkeys · 2014–2021
Fintech and e-commerce products for clients like Gina Tricot, from backend and integrations to cloud infrastructure.
Before that, freelancing from 2008.
