Hi, I’m Mostafa — a tech lead and hands-on engineer with 10+ years of experience building products end-to-end, from embedded systems and firmware all the way up to cloud platforms, web apps, and real-time dashboards. I’ve led software and hardware teams, shipped production IoT devices, built cloud architectures, designed UIs, and delivered complex systems where everything has to work together smoothly. What I do Embedded Systems & Firmware: ARM, ESP32, NXP i.MX, RTOS, custom drivers, Yocto, device bring-up Embedded Linux & Qt/QML: Touchscreen interfaces, system apps, cross-compiled solutions Cloud & DevOps: AWS IoT, EC2, serverless backends, real-time data processing, event pipelines Web & Front-end: React, Next.js, TypeScript, R3F/WebGL, dashboards, data visualization Full Product Development: Architecture, implementation, testing, optimization, and long-term maintenance Selected experience Tech Lead at Triton Sensors — led development of a new IoT device (hardware + firmware + cloud + UI), redesigned the cloud system, and improved reliability, speed, and cost efficiency. Embedded Linux & Firmware Engineer — built Qt/QML interfaces, MIPI LCD drivers, and dual-core communication on NXP i.MX platforms (including Yocto customization). Cloud & App Engineer — delivered real-time dashboards and 3D visualization tools (Intel 3DAT), and a computer-vision health app used in the medical industry. Cross-functional Lead — managed developers, designers, and testers, and delivered 50+ embedded, desktop, and cloud projects. How I work I like taking a problem apart, understanding the real constraints, and offering solutions that are practical and well-engineered. I’m comfortable jumping between layers of a system — debugging a device driver one day, optimizing cloud infrastructure the next, or building a clean front-end to make everything usable. If you need someone who can think across hardware, firmware, software, and cloud — and actually deliver — I’d be happy to talk.
