Rockstar🎓
Top SchoolJohn Johnson is a seasoned software engineer and entrepreneur with 11 years of experience building high‑volume web3 and fintech products from first principles. He co-founded multiple startups including Glider.fi and Smol Studios, and as founding engineer at Matcha/0x helped grow trading volumes from zero to over $1B/month. He blends hands‑on backend expertise—demonstrated by contributions to the 0x-api token registry and API integrations—with product leadership across consumer DeFi, structured products, and exchanges. Previously he led frontend platform efforts at Textio and built critical payroll engines at Ultimate Software, giving him rare domain depth across AI UIs and complex financial systems. Based in San Francisco, he prefers rolling up his sleeves in early‑stage builds and black‑box skunkworks, and his GitHub bio “currently: vibing” hints at a pragmatic, unpretentious approach to shipping impactful technology.
