Sessions
In blockchain, proof of work shows that real effort was done. In your career, open source is your proof of work: a public, verifiable record of how you solve problems, respond to code review and collaborate with others.
That record matters more than ever. AI can now write code and generate pull requests, so what makes a developer worth hiring, promoting or trusting with critical systems? And in Web3, where many teams are distributed and hiring is global, contributions often matter more than a CV.
This panel brings together maintainers, contributors and people who hire engineers to share real stories and practical advice:
What employers look for now: which skills have gained value, and which have lost it.
Standing out: building a visible track record without green-square farming or AI-generated PRs.
Using AI well: making it your advantage rather than a replacement for understanding.
Where open source leads: paths into Web3 and decentralized teams, and growing from contributor to maintainer and leader.
We close the day by looking back at what was built, shared and started. That includes highlights from the talks, pull requests opened in the workshop room, and new connections between the open source and decentralized technology communities. The most important part of the day, though, starts after it ends. We'll show you how to keep going: where to find beginner-friendly issues, how to stay in touch with mentors and maintainers, and how to join upcoming FOSSASIA events, including FOSSASIA Summit 2027. We'll finish with thanks to our speakers, volunteers and partners, followed by a group photo. Don't leave without being in it.
