Bio

I’m a tech entrepreneur with 22+ years of experience building software across industry, academia, NGOs, and startups. As a 3x startup co-founder, I love working on projects that tackle social impact, particularly in relation to climate change. One of my startups I co-founded, Dryad Networks, is pioneering an ultra-early wildfire detection system using ground sensors, addressing a critical environmental challenge. The current startup, Rootd.Earth I am associated with as co-founder / CTO is an attempt to connect people to direct climate action. I love to mentor non-technical founders to confidently lead their tech journey from idea to MVP and beyond. I hope to empower them to align their tech with their mission and step into their role as capable leaders rather than bystanders.

Expertise

  • Technology and tools

    I have worked with technology to build software products and with tools to improve productivity across the tech stack - from desktop / web applications, backend systems, infrastructure as code and software development lifecycle. I enjoy using open source software libraries, tools and frameworks to build products with high impact from the idea stage to robust platforms and services. I am curious by nature and love to learn / work with new concepts and ideas related to technology.

Toolkit

  • AWS (Amazon Web Services) logo

    AWS (Amazon Web Services)

    8 years of experience

    I have significant experience with AWS to cloud provision full stack products and platforms. Although I have used some AWS specific services, my strategy of choice is to build each part of the stack into (Docker) containers and deploy these using IaC automation (Terraform) and container orchestration (Kubernetes). I have considerable experience in security, storage, backup and architecture with regards to cloud provisioning on AWS.

  • Angular logo

    Angular

    11 years of experience

    I have extensive experience building modern web applications with Angular , spanning startups, NGOs, and data platforms. Highlights include leading frontend development for Dryad Networks’ IoT wildfire detection system (Angular + PrimeNG), delivering NRC’s COVID-19 response and beneficiary management apps, migrating TeachSurfing from AngularJS to Angular and developing a data analysis workspace at brewlabs.

  • Azure logo

    Azure

    7 years of experience

    I have significant experience with Azure to cloud provision full stack products and platforms. Although I have used some Azure specific services, my strategy of choice is to build each part of the stack into (Docker) containers and deploy these using IaC automation (Terraform) and container orchestration (Kubernetes). I have considerable experience in security, storage, backup and architecture with regards to cloud provisioning on Azure.

  • Kubernetes logo

    Kubernetes

    7 years of experience

    Experienced in designing and managing Kubernetes-based infrastructures across AWS (EKS) and Azure (AKS). Led deployments using Infrastructure as Code (Terraform, Drone), ensuring scalable, secure, and resilient platforms. Introduced DevOps culture with CI/CD, Docker, and Kubernetes, enabling efficient developer workflows and robust product delivery for startups, NGOs, and enterprise-grade platforms.

  • Miro logo

    Miro

    7 years of experience

    I have used Miro effectively for visualizing user interfaces and workflows - this includes app design, gamification flows and end-to-end user experiences. I have also found it useful for brainstorming around product design thinking as well as visualizing high level project management overview. Another interesting use has been in product feature generation frameworks combined with prioritization decisions eventually leading to short / long term roadmaps.

  • Python logo

    Python

    7 years of experience

    I have extensive experience using Python for backend development, data pipelines, and AI/ML integration. At the Norwegian Refugee Council, I supervised the build of a Python-based payment integration system for private donations. At Dryad Networks, I supported AI smoke detection pipelines. I’ve also used Python with OpenAI APIs, self-hosted LLMs, semantic search, summarization and data extraction tasks.
