Björn Svensson
Open Source Software Developer at Ericsson Software Technology
Gothenburg, Västra Götaland County, Sweden
Summary
🤩
RockstarBjörn Svensson is an experienced open source software developer based in Gothenburg with over 20 years in embedded and systems software and six years focused on modern open-source projects at Ericsson Software Technology. He brings deep C/C++ expertise across telecom and infrastructure components, from packet core and radio base station systems to low-level libraries like FlatBuffers and the popular hiredis Redis client. Björn’s contributions emphasize robustness and correctness—refactoring for type safety in flatcc and hardening asynchronous APIs and tests in hiredis—reflecting a pragmatic focus on preventing subtle C undefined behavior and race conditions. Comfortable across test automation, parser/compiler internals, and production-grade networking code, he combines hands-on maintenance of critical libraries with long-running product experience in telecom. A detail-oriented engineer, he often works on the less visible but high-impact areas (error handling, type fixes, async stability) that improve overall system resilience.
