About me
I’m Abhijay Jain, an open-source developer and FOSS enthusiast with experience across developer tooling, Bitcoin infrastructure, AI products, and modern web technologies. Over the years, I’ve contributed to global open-source programs and organizations including the Linux Foundation, Google summer of code, Block, UnternehmerTUM, and several community-driven ecosystems.
I started my open-source journey as an LFX mentee with Open Horizon (IBM open source) under the Linux Foundation, where I worked on edge computing and infrastructure tooling. Later, I joined SCoRe Lab as a Google Summer of Code 2022 contributor, followed by working with Infinite Reality (previously Ethereal Engine) as an XROS Fellow in 2023, contributing to extended reality and immersive open-source experiences.
In 2023, I was selected again for Google Summer of Code, contributing to Uptane under the Linux Foundation ecosystem, where I worked on secure automotive software update infrastructure. In 2024, I joined Summer of Bitcoin under Block’s Spiral initiative, focusing on Bitcoin and Lightning ecosystem development. I also worked as an Engineering for Change Fellow with Ampaire on impact-driven engineering initiatives and later participated in Digital Product School Munich Batch #22 by UnternehmerTUM, collaborating on product development and rapid prototyping.
Professionally, I’ve worked as a contractual software developer contributing to AI-driven products and full-stack applications. I’m also part of the Bitshala Developer Fellowship and grant program, contributing to BTCPay Server and Bitcoin-native merchant infrastructure. Currently, I’m working on AAIF Goose as a maintainer, contributor, and grant recipient, focusing on AI developer tooling, integrations, and open-source ecosystem development.
Alongside development, I actively contribute to technical writing, open-source maintenance, mentoring, and community initiatives. I’ve also contributed to projects and communities including Fossasia, JBoss, Layer5, Processing, and several independent open-source initiatives.
