About Lasse

I am a strategic IT/Solutions Architect and Technical Orchestrator specializing in global e-commerce infrastructure, system integrations, and process automation. I do not write production-level backend code from scratch; instead, I act as the critical bridge between executive business strategy (EBITDA goals) and development teams to eliminate technical debt and maximize operational ROI.
Driven by an advanced pattern recognition, I specialize in rapidly diagnosing architectural bottlenecks and building high-speed technical solutions. With deep hands-on leadership experience, I understand how to design scalable system landscapes where requirements, budget, and resources are perfectly balanced.

What I Bring to Your Enterprise Projects:

Global Architecture & Scaling: Proven track record of orchestrating the technical infrastructure behind a 10x revenue growth journey. Designed and managed centralized PIM and WMS ecosystems synchronized across 30+ storefronts in 14+ European markets.

Enterprise Migrations & Integrations: Deep expertise in managing high-risk platform migrations (such as Magento to Shopify) and seamlessly connecting core business systems like Dynamics 365 Business Central, advanced inventory platforms (WMS), and complex MarTech tools.

Native Platform Optimization: A rigorous focus on replacing expensive, redundant custom development with high-efficiency native system configurations, turning 30-hour development traps into 1.5-hour native deployments.

AI Automation & Operations: Expert in conceptualizing and prototyping custom AI tools and workflow automations (via Shopify Flow, Make, Zapier or API logic) that eliminate manual bottlenecks, saving organizations hundreds of hours annually.

Available for Fractional CTO/Architect roles, technical advisory, and whitelabeled enterprise project udrulninger via partner agencies.
