Senior🎓
Top SchoolKieran O'brien is a senior software engineer and tech lead with 11 years' experience building production systems across SaaS, telecoms, travel and blockchain, now leading Blockdaemon’s Earn Stack as Product Owner & Tech Lead. He combines end-to-end ownership—from architecture and hands-on implementation to delivery and operations—while mentoring engineers and aligning cross-functional stakeholders. Deep experience in API and platform design, reliability engineering, and pragmatic solutions has driven measurable product improvements, particularly in DeFi primitives like multi-DEX and bridge integrations. Previously he led node operations and protocol onboarding, consolidating deployment tooling and cutting maintenance overhead through reusable Ansible roles. Comfortable in small, high-impact teams, he blends backend systems work (Go, Java, Python) with operational excellence and customer-facing delivery. Fluent in turning complex protocol and integration challenges into maintainable platforms, he often bridges product strategy with implementation details.
