About
I am a Software Architect and Full-Stack Developer at home in the .NET and React ecosystem. For several years I have been building web apps, mobile apps and APIs across the entire lifecycle: architecture, data modelling, implementation, deployment and operations. On most projects I additionally take on project leadership or a technical lead role, depending on what is needed. Currently, alongside hands-on engineering, I am strongly engaged with the topic of AI. I help drive the AI transformation on an organisational level with the ambition that those topics actually land in the day-to-day work of the teams. When I'm not at the keyboard you'll find me cruising on my vintage Vespa or my Harley, or enjoying time with my small beloved family.

Some projects I worked on
Helion Online Offer Calculator (offerte.helion.ch)
Complete ground-up rebuild of Helion's online offer calculator, replacing the previous solution. Together with the team we built the new platform from scratch on React, including a dedicated component library and design system that carries the entire experience and gives the team a solid foundation for future products.
Rapid Prototyping for CSS Krankenversicherung
Part of an interdisciplinary innovation team between Sitewerk and CSS Krankenversicherung. Following a Design Thinking process we explored the topic of mental health, ran interviews with the target group, facilitated ideation workshops and built physical as well as clickable Figma prototypes that we validated with real end customers within just a few weeks.
PowerBuddy Smart Meter Reader (App & Backend)
PowerBuddy is a smart-meter reader that sits on Swiss smart meters (Landis+Gyr, Semax, Ensor, NES) and streams high-resolution consumption data every 5 seconds via MQTT – either to a local broker or to the cloud on Swiss servers. As main developer at Sitewerk I built the native mobile app together with the full backend, including a dedicated Identity Provider (IDP). The app drives the plug-and-play onboarding via QR code, the Wi-Fi configuration of the device and the live visualisation of the energy data.
Democratic Participation Mobile App for Plural AG
As strategic partner we accompanied Plural from the technical concept through implementation to running the platform. The challenge: get a working MVP into the App Store within a few months. We chose a web-first approach to share as much code as possible between the React Native mobile app and the Next.js web app via WebView, on top of a .NET Core backend in Azure as the scalable foundation. Awarded Gold in the "Public Value" category at Best of Swiss Web 2026 and ranked 3rd in the overall Master of Swiss Web 2026.
Internal Control System (ICS) for the City of Olten
Cloud software for the internal control system (ICS) of the City of Olten. Together with the customer we worked out the requirements for a tool that combines a broad feature set with very simple usability. The result: an Angular SPA on top of a .NET Core backend with PostgreSQL, hosted in the Azure Cloud (Switzerland) – productive since summer and the seed for what later became our adminera iks product.
Multi-Tenant ICS Platform (adminera iks)
Following the City of Olten project we evolved the solution into adminera iks, a multi-tenant SaaS for ICS and risk management. As tech lead and main developer I architected the multi-tenancy model and the data model and drove the implementation. The platform lets several municipalities and companies run their internal control processes side by side with strict tenant isolation.
sun2wheel Cloud Platform & Mobile App
Cloud platform and mobile app for sun2wheel's intelligent EV charging system, which orchestrates consumers, producers and storage and enables bidirectional charging. We deliberately translated technical units like kWh into everyday language (kilometres of range, CHF saved). Tech: .NET Core backend on Azure with PostgreSQL, NATS for the real-time bidirectional communication with the on-site hardware, an Angular SPA for admins and an Ionic-based PWA for end customers.
Finoba Trust Services PWA
PWA for the trust service provider Finoba AG. We built the app following a lean MVP approach so that real customers could test it early, then iterated on top of the modular foundation. Customers scan and submit receipts via smartphone, chat with their trustee, book appointments and manage their subscribed services – customers and trustees share the same app, with content driven by a role and permission system. Tech: Ionic PWA on a .NET Core / PostgreSQL backend in Azure.
PV Offer Configurator for Helion (THEIA platform)
Multi-tenant offer configurator for Helion (AMAG) that lets end customers generate a personalised PV offer with ±15 % accuracy in just a few clicks. The wizard pulls 3D building data from swisstopo (swissBUILDINGS3D) for orientation, slope and surface, while a CPQ rule engine plus ERP integration keep prices and product data in sync. As part of the THEIA e-commerce platform the same configurator is white-labelled to partners like IKEA Schweiz, Meier Tobler and Audi – today around 80 % of all Helion enquiries come through it.
Shopify Online Shop for Doruntina Azemi
Shopify online shop for Swiss artist Doruntina Azemi (DA), who designs and crafts wearable and collectable art – from the Ray Riviera collection to hand-painted originals and hand-illustrated prints. End-to-end work via webdigi: visual design, theme implementation in Liquid, shop configuration, product and collection structure, and the launch of the new brand presence.
Company Website for webdigi Alain Kaiser
Designed and developed a modern, responsive website for my software engineering consultancy. Built with React and Gatsby.js for exceptional performance, the site features a headless CMS architecture using Sanity that enables easy content management. The clean design and intuitive navigation highlight my portfolio while providing potential clients with comprehensive service information.
Website-Template Framework
Created a modular website framework that accelerates the development of custom client websites. This reusable component library, built on React and Gatsby.js, includes pre-designed elements that can be rapidly assembled into unique websites. The framework integrates with Sanity for content management, allowing clients to easily update their content while maintaining design consistency.
Website & Webshop easymining.ch
Developed an integrated website and e-commerce solution for easymining.ch, combining content marketing with product sales. The architecture leverages Shopify's robust e-commerce backend while using Sanity to manage product descriptions and marketing content. This hybrid approach provides a seamless shopping experience while giving the client flexible content management capabilities.
Website V2 for Digital Minds GmbH
Redesigned and rebuilt Digital Minds GmbH's web presence with a Next.js front-end and Sanity as a headless CMS, with server-side rendering for SEO and editor-friendly content areas the client can fully control. Development was finished and the site is fully functional, but it ultimately never went live on the production domain – the latest build is still reachable via the Vercel preview deployment linked here.
Werder-App Business Process Application
Engineered a specialized business application for documenting and managing recurring work processes that couldn't be automated through conventional means. Built on Angular and .NET Core with an MSSQL database, this application streamlines workflow documentation and improves operational efficiency. The solution includes customizable form generation and robust reporting capabilities.
