Platforms

One standard. Every platform.

Real products and a clearly labelled foldable concept show how Pahl Digital Art designs for web, desktop and mobile.

01 / Apps

Pahl Product Index

Four products. Four clear purposes.

Swiftli Launch Pad, Smart HR, Smart Companion and Beste ÖV are distinct products built with the same care in design and engineering.

02 / Web

Swiftli Smart HR

Native precision. Choreographed for the web.

The original Smart HR SwiftUI surface is translated faithfully into an animated web visualisation — not a reconstruction of the web demo.

Swiftli Launch Pad

At home on the Mac.

Swiftli Smart HR and Swiftli Launch Pad are real macOS products, built for native workflows and precise interaction.

Swiftli Smart Companion · Beste ÖV

One design language. Two form factors.

Source-faithful views of Smart Companion and Beste ÖV respond from iPhone to iPad as the available space changes.

05 / Windows

Lohnhelfer · Windows 11

Payroll work. Local on Windows.

Lohnhelfer installs as a local Windows 11 application and opens its web interface in the browser on the same device.

Beste ÖV · Foldable concept

Start compact. Open up to more.

A clearly labelled foldable concept carries the existing Beste ÖV design language from a narrow view to an unfolded layout.

Tech services

Technology that holds up day to day.

Alongside my own products I take care of the technology behind them: network, devices, cloud and data protection—set up, explained and looked after.

AI from hands-on development

AI training & optimisation.

Adapt language models to specific tasks, run them locally and test them carefully. My work on Swiftli Smart HR spans custom training data and LoRA adapters through to quantisation and prefix caching.

Explore the AI service

  • Data & training

    Prepare datasets, evaluate LoRA fine-tuning and adapt models to languages, domain tasks and structured outputs.

  • Quantisation

    Assess memory use alongside quality, from quantised model weights to the KV cache used for longer contexts.

  • Prefix caching

    Reuse matching prompt prefixes, manage KV states and apply result caches where appropriate to avoid repeated computation.

  • Test & integrate

    Measure output quality, time to first response, generation speed and memory on the target device. Integrate local models with MLX into native Apple Silicon applications.
