Our Speakers
Lucas Eduardo Rainett, Platform Architect, Fullstack & Cybersecurity
I'll walk through how I turned my gaming PC into a fully self-hosted AI stack from a first experiment with Home Assistant and Ollama, to running Open WebUI, to my current setup with the Hermes Agent over Matrix. Along the way I'll cover the open-source tools involved (Ollama, paperless-gpt, local voice control with Whisper/Piper), the security architecture protecting it (VPN, reverse proxy, OIDC auth), and what I learned trying to make privacy-respecting tools convenient enough for the non-technical people in my life.
Ma Quanyi, Founder of Libra
AI coding agents can now read issues, edit code, run tests, open pull requests, and even respond to review comments. Yet most developer workflows still reduce all that work to a final commit and a CI result. This talk explores what’s missing in the agent era: how to capture an AI’s context, tool usage, failed attempts, validation, and decision-making, so AI-generated changes become reviewable, auditable, and trustworthy—not just another diff.
Jimmie Wang, Founder of Myfield.one
AI can build products faster than ever—but it can also amplify mistakes, complexity, and information overload. Building Myfield with AI taught me that the real challenge isn’t smarter AI, but staying in control. This talk will share practical lessons from shipping a real product with AI, common pitfalls, and why user-owned data is essential for keeping humans—not AI or platforms—in control. The future isn’t about AI replacing humans. It’s about humans learning how to steer AI.
Open Source Singapore
Open Source Singapore (formerly Free and Open Source Meetup) is a community dedicated to promoting awareness, knowledge-sharing, and adoption of open source technologies. We bring together developers, enthusiasts, and industry professionals to exchange ideas, collaborate, and champion the values of openness, transparency, and innovation in Singapore’s tech ecosystem.
