Senior🎓
Top SchoolLauri Lehtinen is a software engineer with 10 years of experience building resilient back-end systems and consumer-facing services across financial services, online retail, and location-based mobile platforms. He blends deep Java and JavaScript expertise with hands-on experience in SOA, REST, concurrency, cloud (AWS), CI/CD and TDD, having moved between roles from founder of a browser-based PDF startup to staff engineering and SRE positions at Wise. At Wise he led integrations for cross-border payments and operational tooling, and more recently contributed to data pipeline improvements in the popular open-source PipelineWise project (notably Snowflake target enhancements). Now at Lightyear, he applies that mix of product empathy and infrastructure rigor to help build a European investment platform. Colleagues describe him as the engineer who both architects scalable systems and enjoys diving into tricky operational problems—“if there was a problem, yo, I'll solve it.”
