Mikkel Nielsen is a Lead Software Engineer based in Aarhus with 14 years of experience building and modernizing backend systems for high-throughput platforms. He has driven major rewrites and migrations—most recently moving a high-traffic PHP site to Kotlin for Better Collective—and architected resilient merchant APIs, an in-house billing engine, and a Snowflake/dbt data warehouse while at Clearhaus. Comfortable across the stack, he combines hands-on development with systems design and has repeatedly displaced legacy, inflexible solutions with scalable replacements. His career spans fast-growing cloud startups and enterprise integrations, and he brings a pragmatic customer-facing perspective from early roles that involved direct user interaction and operational support. Colleagues describe him as detail-oriented and product-focused, able to translate complex requirements into maintainable, production-ready systems.
