Summary
👤
Senior🎓
Top SchoolAndrás Sziffer is a software engineer with eight years of experience, currently building Spectacles AR software at Snap Inc. and studying Computer Science Engineering at Pázmány University with a specialization in software development. He brings strong mobile expertise in Kotlin, Swift and Java, honed through roles as an Android developer at SignAll and as the creator of Challenger, a cross-platform fitness tracker that integrates sensors and weather-aware features. Based in Vienna, he combines product-focused engineering with a creative side — running a long-standing photography business covering portraits, weddings and food. Comfortable shipping end-to-end mobile experiences, he blends applied academics with hands-on freelance product work and an interest in AR systems that sits slightly outside the typical mobile developer path.
