Summary
👤
Senior🎓
Top SchoolJakub Czekański is a Senior Software Engineer with 13 years of hands-on experience building Android and AOSP systems, currently working on Reality Labs projects at Meta via intive. He blends high-level Android app development with deep low-level work—kernel modules, system maintenance, and emulator internals—demonstrated by contributions to PCSX-Redux and automotive CAN bus testing in commaai/opendbc. A Kotlin-first developer, he’s reduced crash rates and migrated complex AOSP platforms for video-conferencing hardware, and has led Android architecture and CI efforts in fintech and consumer startups. Based in Warsaw, he spends spare time developing emulators and exploring hardware/endianness quirks, bringing a rare combination of systems-level curiosity and production-grade mobile engineering.
