Frett27 Consulting - Software Craftsmanship

Software design and implementation — from the real business need to software that runs and can evolve over time.

From code to real usage: cognitive load, ease of adoption, clear journeys, human–machine interaction — with deliberate attention to visual identity, UI/GUI consistency, and readable layouts so end users and stakeholders stay aligned on the same problems — including GIS and geospatial stacks in production — because complex systems rest on simple, organized building blocks.

Selected work

Connected devices, mobility, and open-source proof first; last card: an innovation in orchestration and workflows — active work in progress at Coexya (MUI).

IoT platform — Rustiq IOT

IoT platform: long-running battery prototypes, custom board, supervision — from requirements to field-ready delivery.

Details →

MAAS architecture — metropolitan scale

Metropolitan MAAS architecture: streamlined gateway, audit, and event hub on Java / Go / Kafka.

Details →

Split-flap display — open source

Open source driven split-flap: full hardware + software chain, from control to the physical display.

Details →

Innovation (in progress) — business orchestration & VM — Coexya (MUI)

Work in progress: innovating on a dedicated language, VM, and workflows to orchestrate payments, data, and rules — aiming for a lighter path than heavyweight BPMN factories (e.g. Camunda).

Our Services

Software Architecture

Maintainable software architecture

Map, slice, decide: useful views (diagrams, screen flows, lightweight prototypes), module boundaries, and choices that survive the first release — tying engineering, visual guidelines, and UI into a shared language for users, business roles, and stakeholders.

Embedded Systems Development

From prototype to industrial embedded

Firmware, hardware constraints, industrial or field conditions: connected devices built for a long service life.

GIS Solutions

GIS — geographic information systems

End-to-end GIS expertise: cadastre, web mapping, spatial databases and services at scale — data architecture, business integration, and long-running operations (models, operational editing, OpenLayers where relevant) — symbology, legends, and map UX that stay legible for both end users and stakeholders (decision-makers, domain experts, engineering).
