Senior🎓
Top SchoolPetri Jahnsson is a seasoned systemutvecklare based in Gothenburg with nine years of professional experience building frontend-first applications using JavaScript, React/React Native and the MERN stack. He pairs modern web skills with a less obvious background in electronics and low-level programming (Assembler, C, C++), which gives him a practical edge when bridging hardware-near requirements and user-facing systems. Petri has delivered software across public sector and automotive domains (Trafikverket, Volvo Cars, Aurobay) and has experience acting as both developer and Scrum Master in agile teams. Comfortable with CSS/HTML and full-stack Node/Mongo workflows, he focuses on reliable, maintainable implementations and pragmatic delivery. Known for steady contribution across long-term contracts, he brings a blend of hands-on coding, systems thinking and cross-disciplinary curiosity to complex engineering problems.
