I led and initiated a frontend rewrite at Aurbjörg, where more than 30 React microfrontends bundled with Webpack were consolidated into a single Vite + React SPA. The goal was to significantly improve both product quality and UX, while simplifying development and maintenance for a small team. The new frontend is written in TypeScript, uses Zod for type validation, React Query and search params for state handling, and shadcn + Radix UI + Tailwind as a component foundation. I also implemented PWA capabilities such as background updates, user notifications, and lazy loading.

I migrated authentication from island.is to passwordless authentication with SuperTokens, and temporarily moved authentication for the legacy site to Auðkenni after island.is was discontinued.

I made major improvements to the subscription and billing system. This included resolving expensive errors where users were not billed, billed twice, or deleted incorrectly. All subscription handling was integrated into Hangfire, logging was significantly improved, and support for discount codes was implemented.

I redesigned and implemented a new mortgage calculator in the frontend, focused on better flexibility, more accurate calculations, and improved user experience.

AGR develops inventory management and purchasing optimization software for medium and large companies. Highlights of my work at AGR include:
AGR Client: A major rewrite from AngularJS to Angular. I introduced ESLint rules, strict type checking, data validation patterns, i18n/l10n, data formatting, timezone and session management, and application bootstrap. I contributed across most modules and features, and worked with Highcharts and AG Grid.
AGR Pool: NestJS backend and API for shared data in the AGR ecosystem (translations). Deployed as a Docker container on Azure App Service with MS SQL. I also built an Angular client for managing languages and translations, including integration with Google Translate API suggestions and dynamic loading of CLDR locale files.
Release Page: Python scripts that fetch data from GitHub Releases and generate static HTML pages. Deployed on Azure VPS with Nginx, Certbot, and Webhook for automated build and deployment. I set up similar continuous delivery for AGR documentation.
AGR Service: Backend rewrite from .NET to .NET Core to prepare the AGR solution for cloud architecture (SOA/microservices). I set up CI pipelines to ensure EF Models stayed in sync with the database-first schema and enforced linting with EditorConfig.
Login Portal: Angular client for the AGR Essentials cloud solution.
Support Client: I designed and built a lightweight Angular app I called Snek for tenant overview and administration in AGR Essentials. All components were standalone and lazy-loaded, with a Service Worker (PWA) that prefetches new releases for smooth continuous delivery.
State Management: I implemented Redux-like state management in Angular using RxJS. Services stored data in Subjects (store), action interfaces triggered API synchronization (effects), and reducers updated state. I rewrote the Reports section of AGR Client in this style and built all components in a declarative, reactive style.
Testing: E2E testing with Cypress (previously Protractor), and unit/component tests with Cypress and Jest (previously Karma).

Development of a reusable software solution and supporting tools to accelerate production of interactive 3D map experiences. The project was designed for national parks, nature reserves, visitor centers, and exhibitions to provide guests with insight and overview through an interactive touch interface.
Final report, presentation with video demo, recommendation.

I designed and developed a game for an exhibition about the medieval monastery at Skriðuklaustur in Fljótsdalur. The game is a treasure hunt and quiz experience where players use AR on smartphones to find clues and hidden treasure. The project started as an innovation project funded by the Icelandic Student Innovation Fund and continued through winter 2017-2018. The first version was pilot-tested at Skriðuklaustur in summer 2018.

Alongside my studies at RU, I worked as a teaching assistant. The role included helping students in lab sessions and reviewing assignments. Courses included Problem Solving, intensive 3-week programming (C++), and Data Structures (C++).

Prototype development of real-time indoor positioning hardware with 15-30 cm accuracy. Implemented communication over Ultra-Wideband (UWB) using a Decawave module to measure message flight time, then compute distance and send it to smartphones via Bluetooth. You can read more about the project, and see a photo of the prototype. The work involved significant research and gave me a solid introduction to electronics and C++ programming.

Integrated the Bokun booking system into both the app and website for Friend in Iceland, along with other web solutions and administrative handling of booked tours (including FileMaker setup).

Promoted Bara health products as Marketing Manager. My role included website development, photography, advertising, copywriting, translation, brochure creation, packaging and brand design, and ad distribution. The output of this work can be seen on the Bara website.

Supply truck driver for centerline and edge-line road marking on major roads and newly laid asphalt in Hordaland, as well as Sogn og Fjordane in Norway. Photos here.

Designed and developed the Draumaliðið website, now SportHero.is. I implemented an ecommerce setup that allowed the company to sell photos from tournaments. I have also maintained and updated the site regularly since 2011.

Guitar teacher at the school, teaching both children and adults in small groups of 2-4 students, typically 4-6 groups each winter. During winter 2010-2011 I also taught at Thorvaldur Bjarni's music production school.
