GitHub statistics Top languages

I enjoy engineering complete systems rather than isolated pieces:

Schematic & PCB → embedded firmware → communication → application software → testing & documentation

I use GitHub as both a project workspace and an engineering notebook, keeping source code, hardware files, experiments, reports, and reusable tooling together whenever that improves traceability.

• Embedded systems: STM32, ESP32, Arduino, FreeRTOS and C/C++ firmware architecture.
• Hardware and PCB: schematic review, component selection, PCB layout and reusable Altium libraries.
• Robotics and automation: motor control, communication protocols, timeout protection and recovery logic.
• Software engineering: Python desktop tools, dashboards and testing applications.
• AI and computer vision: intelligent classification and workflow automation.

Selected for technical depth, completeness, documentation quality, and relevance to embedded systems, control, PCB design, robotics, and engineering software.

• Understand the system: interfaces, constraints, failure modes and actual operating conditions come first.
• Design for verification: logs, test points, reproducible builds and acceptance criteria reduce guesswork.
• Prefer safe failure modes: timeouts, validation, recovery paths and conservative assumptions are part of the design.
• Measure before optimizing: performance work should be based on evidence and documented decisions.
