Senior🎓
Top SchoolKeri Szafir is an electronics designer and founder with 11 years of hands-on experience building and servicing tube amplifiers, audio processors and bespoke hi‑fi equipment from her Gdańsk-based workshop, Keritech Electronics. She blends formal engineering training (MSc in Chemistry) with practical skills in PCB design, SMD assembly and diagnostics gained across R&D and field service roles. Known locally as a “vacuum tube witch,” she pairs vintage‑tech passion with modern problem solving—tackling both intricate schematics and gritty installation or repair work. Keri documents her craft on a scrappy but insightful YouTube channel that showcases cost-conscious builds and restoration techniques. Comfortable moving between lab bench, soldering iron and oscilloscope, she specializes in turning resource constraints into creative engineering solutions.
