Senior🎓
Top SchoolGarrett Heaver is a consultant, architect and security specialist based in Dublin with over 14 years of hands-on experience building secure, high‑volume systems across AWS, Microsoft and Java ecosystems. He combines postgraduate cybersecurity training and a broad certification portfolio (including AWS Solutions Architect and Security Specialty, C|EH and multiple Microsoft credentials) with a history of delivering for clients from startups to multinationals such as Fidelity, Aon and Premier Lotteries Ireland. Equally comfortable as a full‑stack developer and as an architect, he has designed everything from lottery and gaming platforms to financial audit automation and a private pilot debriefing system. Known for a practical, can‑do approach that earns repeat engagements, he blends deep operational knowledge of cloud services, databases and web frameworks with security-first design. Outside work he’s a private pilot and scuba diver, a detail that surfaces in projects like the flight debrief platform and reflects his appetite for complex, safety-critical systems.
