Top SchoolTim Johns is a Senior Software Engineer with 13 years of hands-on experience building full-stack web platforms, embedded systems, and developer-focused tooling.

A seasoned educator and mentor, Tim has transformed novices into job-ready engineers via a 14-module full-stack curriculum and 170+ practice exercises, and was repeatedly voted favourite mentor at Lighthouse Labs. His background also includes low-level firmware and PCB design for high-precision IMU loggers, demonstrating rare fluency across cloud services, functional programming, and hardware. At Mercury he continues to apply this cross-disciplinary perspective, pairing practical delivery with deep system design and a knack for turning complex academic-style requirements into user-friendly products.
