Senior🎓
Top SchoolHasstrup Ezekiel is a Senior Backend Engineer with 8 years of experience building resilient, data-driven platforms for education and freelance marketplaces. He has led engineering teams and product delivery as Founder & Technical Lead at Haldane Engineering, where he designed payroll and conflict-resolution algorithms to enable global payouts across 100+ countries. Previously he maintained and improved API backends for large-scale education products at Pearson, Clutch Prep, and Andela—shipping diff/merge algorithms, LTI integrations, syllabus parsing, and grading systems that materially improved student outcomes and B2B conversions. Comfortable across Ruby on Rails, Typescript/React, Postgres, Redis, and cloud infrastructure, he pairs pragmatic architecture with hands-on implementation. Currently contributing to mentorship and alumni engagement tooling at StellarUp while still iterating on product infrastructure from his startup work. Outside engineering his GitHub bio’s laconic “cooling” hints at a quietly focused, systems-first approach to solving hard product problems.
