Summary
👤
Senior🎓
Top SchoolRobert Treen is a retired engineer and technologist with a B.Sc. in Computation and a diverse career spanning broadcast electronics at the BBC, medical ultrasound servicing, adult education, and nearly two decades running his own technical consultancy, Radioshare Limited. He combines hardware roots (FORTRAN/COBOL-era experience, microcontrollers and bespoke electronics) with modern software work in Java and Python, and has contributed front-end improvements to the well-known dash.js MPEG-DASH reference client focused on adaptive bitrate and playback quality. Known as a "think tank" problem-solver, he prefers thoughtful, quality-driven work over rushed deadlines and excels at end-to-end projects—often finding solutions to problems others deemed impossible when technology permits. He also brings practical media expertise in broadcast systems, MIDI/audio engineering and theatrical projection, and values clear documentation and maintainable designs. Based in Stratford-on-Avon, he now prioritises projects that interest him, learning selectively and avoiding areas (like complex mechanics) that don't play to his strengths.
