What I'm looking for

With 20 years of experience, I'm a problem solver first, coder second. I adapt quickly to any tech stack to get the job done. I love mentoring, keeping solutions simple, and focusing on the user's pain to deliver real value, not just lines of code. I'm looking for a collaborative team where we can build great things together.

I've led critical platform modernization work for SDC, acquired by Netcompany, including a Netbank accessibility overhaul across more than 40 Nordic banks. I aligned technical delivery with bank stakeholders and coordinated UAT and rollout approvals.

I built custom AI-agent integrations in the OpenCode ecosystem, designing context-management and execution strategies that reduced overall LLM token costs by 80%. I also refactored navigation and dynamic contrast systems to support keyboard access and WCAG compliance.

At Multivision, allocated to Celfocus, I led the Front-end Chapter and helped move Vodafone Internet in the Car from legacy JSP to ReactJS and Next.js for brands including Porsche, Audi, and Ford. I also supported a 27-language WebCenter Content environment and its transition to Contentful and GraphQL.

Over 15 years at Fenix.com, I led front-end and back-end Agile squads, modernized a Transparency Portal used by 200+ public agencies, and built products including a procurement quotation platform and a React Native payroll app.
