• Legacy modernization: Maintain and incrementally modernize established production systems, delivering new functionality while preserving compatibility and stability.
• Government integrations: Develop and maintain integrations with Försäkringskassan, including electronic forms and specialized administrative workflows.
• Relatives' portal: Rebuilt a legacy portal as a containerized Spring Boot API and SPA frontend, preserving existing workflows and BankID authentication and signing.
• Staff signing application: Developed a separate application for staff to review, verify and electronically sign timesheets.
• Platform modernization: Progressively replacing a monolith with independently deployable, multi-tenant services; co-designed the architecture and led implementation, developing with Podman locally and targeting Kubernetes via Argo CD.
• AI-assisted engineering: Established a shared, Git-versioned architecture repository used across multiple coding agents for plans and design decisions, with human review of every generated change.

Consulting across unfamiliar codebases, technical stacks and business domains. Joined Consulence following an established development collaboration during my time at GearsERP. Tight deadlines = "we needed this yesterday"

• QlikTech — Built a documentation pipeline transforming proprietary XML to HTML, replacing MadCap Flare output for a large technical documentation suite. Learned more about XSLT than anyone should.
• LinkMobility — Built a digital loyalty card platform end-to-end (UI, API, database), sold through to national retail chains, with payment provider integrations. They all claim to be "simple". They're all lying.
• Tunstall — Maintained and extended healthcare planning and reporting systems, fixing critical production issues where reliability was non-negotiable.
• Avensia — E-commerce development with integrations to Microsoft Dynamics NAV and product catalogue systems.

Full-time until 2015; continued providing technical support alongside consulting through 2021.

Co-founded GearsERP as one of three, building a new B2B platform from scratch. Led architecture, integrations, product development and delivery, and shared the commercial and operational work of running a small software company. So. Many. Kanban. Boards.

• From demo to customers: Signed the first customer after demoing the new platform, then grew to 10+ clients through word of mouth.
• Real-time ERP integration: Built bidirectional Microsoft Dynamics NAV integrations for orders, inventory, pricing and customer data, preserving customer-specific pricing and ERP business rules across catalogues containing thousands of SKUs.
• Multi-tenant platform: One codebase serving every client, each with its own styling, business rules and choice of features from a modular component system.
• Offline-first trade-fair ordering: Tablet ordering used at live events with no connectivity; orders synced once back online, with conflict resolution when several reps edited the same customer.

Websites, intranets and e-commerce platforms on an in-house CMS, through the transition from VBScript/JScript to .NET. Worked directly with clients on requirements.

• Led the development team building custom CMS, e-commerce and corporate intranet solutions.
• Established coding standards, development workflows and quality assurance processes across the team. Got pushback. Then more pushback. Eventually they agreed (mostly).

Web application development and technical support.

Early commercial web development and cross-browser interface engineering, back when that meant Netscape 4, IE 4 and a fair amount of hope.

Studies in information systems, database design and systems analysis.
