Senior🎓
Top SchoolTiddo Langerak is a product-focused engineer with 13 years of experience building reliable, high-performance systems across startups and large organisations, currently shaping product engineering at Lightyear from Tallinn. He has a strong track record driving architectural improvements and operational excellence—at Sage Earth he raised test coverage from near 0 to >90%, introduced observability and CI/CD practices, and built fault-tolerant scheduling and emissions calculation frameworks for scalable carbon accounting. At Wise he led cross-organisational initiatives including a Mastercard integration that migrated 2M+ cards with zero disruption, and introduced anomaly detection to reduce on-call fatigue. Comfortable across the stack, Tiddo blends embedded and front-end roots with deep backend and distributed-systems expertise to turn hard problems into elegant, production-ready solutions. He also brings a tendency to codify domain knowledge into reusable frameworks and security-first approaches like row-level data isolation, accelerating long-term extensibility.
