What I'm looking for

I seek roles where I can lead full-stack development and automation efforts, collaborate cross-functionally in Agile teams, and deliver measurable operational impact.

I am a lead developer with hands-on experience building full-stack web solutions, automations, and business process improvements using Next.js, React, JavaScript, TypeScript, Node.js, Python, SharePoint and Power Platform. I have led end-to-end projects that delivered measurable impact, including a process automation that reduced annual costs by 2 million SEK, while mentoring junior developers and collaborating closely with product owners in Agile teams.

Earlier I worked as a QA tester executing functional and regression testing across environments and documenting clear bug reports in Jira. I hold a Bachelor's degree in Manufacturing Engineering, contributed to university web projects using React, and bring strong problem-solving, documentation, and cross-functional communication skills to drive reliable deliveries.
