1. May 2025 - Current Contract

   Senior Fullstack Developer

   Microniq Business Automation ABWorkforce Management Platform

   I'm one of the lead developers on a workforce management platform that helps service companies plan staff, vehicles, and daily operations. I own large parts of the Resource Planning Schedule, the platform's core planning surface, where I built drag-and-drop assignment with collision detection, snapshot-based undo/redo, optimistic locking with crash recovery, and live schedule validation against a constraint-solving engine.
   
   I work across the whole stack: a React and Material UI frontend, a layered Node.js, Express and TypeORM API on PostgreSQL, Auth0 authentication, a dedicated worker syncing Fortnox financial data over WebSockets, and GCP infrastructure defined in Terraform.
   
   I also own much of the platform's technical documentation — the architecture and domain references the team works from — along with the CI/CD pipelines that build, test and deploy each service to dev and production.

2. March 2026 - August 2026 Contract

   Senior Fullstack Developer

   Ingka Group (IKEA)Edge Engineering

   I worked with Ingka's Edge Team, a group recognized internally as a go-to resource for cross functional collaboration, specializing in rapid prototypes and turning ideas into fast realities.
   
   My main focus was a customer-facing service running globally across several regions, where I took a new interactive frontend feature from proof of concept through to production. The work spanned client-side asset handling and caching, internationalization across a wide range of markets and languages, and a semantic accessibility pass, together with the supporting Python and FastAPI endpoints behind it.

The frontend work was built on IKEA's Skapa design system, with accessibility requirements applied throughout.

5. September 2021 - January 2024 Employment

   Team Manager

   GESHDO Now AB

   As Team Manager I led a cross-functional team of eight — software developers, a Scrum Master and a UX Engineer — alongside my own client assignments.
   
   I ran regular one-to-ones and individual development planning, and created space for knowledge sharing across a team whose members spent their days at different client sites. A large part of the role was keeping people supported and motivated through changing assignments, and helping each of them grow in the direction they wanted to go.

   • Focused on complex, state-heavy web applications, cloud infrastructure on GCP and Terraform, and accessible interfaces used across multiple markets and languages
   
   • Taking technical ownership inside each assignment — software architecture, technical documentation, code review and CI/CD — and working directly with product owners and stakeholders on scope and prioritization

   Procommerca

   During my second internship, I developed data migration systems that streamed data between databases via an internal API.

    Store Manager

    Hemmakväll

    I ran the Helsingborg store with full responsibility for staffing, scheduling, budget and results. From January 2014 I took on a second store in parallel and led both locations and their teams at the same time. The work covered recruitment, coaching and daily operations, along with the forecasting and scheduling that keeps a retail floor correctly staffed — the same planning problems I build software for today.
