Hi, I'm Kristoffer. I turn complex problems into reliable software.
Most recently: designed an event-driven reconciliation engine
About
I'm a full-stack software engineer with 8+ years of experience building data-intensive platforms across fintech and clean energy. I specialize in designing scalable, robust architectures. Most recently, I led the rebuild of FloQast's reconciliation engine to support enterprise-scale growth. Prior to that, I architected the APIs and data infrastructure behind a solar financing platform that facilitated over $2M in annual loans.
I enjoy the full lifecycle: shaping architecture, shipping production code, and growing alongside the engineers I work with.
Off the clock you'll find me exploring Austin with my two kids and wife, learning a new guitar solo, or lost in a book (yes, The Lord of the Rings is the best fantasy series of all time). I'm also an Eagle Scout and a Baylor Bear for life. Sic 'em!

Event-Driven Reconciliation Engine
Leading design of an event-driven reconciliation engine serving FloQast’s largest enterprise customers. Decomposed a synchronous monolith into a queue-backed, idempotent pipeline that scales horizontally per customer.
