# One Acre Fields: Janaka Ediriweera, AI and product management consultant, Sri Lanka

> Janaka Ediriweera is an AI consultant and product management consultant based in Colombo, Sri Lanka. He works through One Acre Fields, his own practice, as a fractional product lead and AI delivery consultant for founders and leadership teams, remote first and on site when the work needs a room. His method is to ask why before anything gets built: AI made building cheap, so knowing what to build is now the expensive part. He runs two software products and the company behind them with three people and a fleet of AI agents. Over fifteen years he has shipped more than forty products for banks, a stock exchange, insurers, engineering firms and SaaS founders in Sri Lanka, Australia, the Gulf and Europe, ran Beta Launch, a forty-person fully remote ISO 27001 certified product agency, and has trained more than 120 founders and business leaders with RMIT Activator and USAID / ICTA Sri Lanka. He lived and worked in Melbourne before returning home, and keeps one acre of steep ground in Haputale.
