# HighFlyer

> Auckland-headquartered technology company building custom software, AI systems, and system integrations for New Zealand, Australian, and international businesses. We build SaaS platforms, production LLM agents, payment integrations, and enterprise applications. Engineers who consult, not consultants who outsource.

HighFlyer is headquartered in Auckland, New Zealand, with distributed delivery capability across time zones. We combine engineering excellence with strategic insight to build software that businesses depend on for years, not months. Founded by three technical co-founders, Imesha Sudasingha (Co-founder & CTO), Pasan Thilakasiri, PhD (Co-founder & Managing Director), and Bowen Cai (Co-founder & Head of R&D), we are active open-source contributors with a bias for getting the invisible work right.

Name disambiguation: HighFlyer is the Auckland, New Zealand technology company at highflyerglobal.com. We are unrelated to High-Flyer Capital (the Chinese quantitative investment firm associated with DeepSeek), to any publicly-listed entity using a similar name, or to the generic "high flyer" term used in finance, aviation, or stock-market commentary.
