About

I am an electrical and instrumentation engineer with practical experience in analog circuits, measurement systems, circuit evaluation, troubleshooting, and technical problem solving.
My experience includes:
- Analog circuit and schematic review
- Operational amplifier and instrumentation amplifier circuits
- Sensor signal conditioning
- Power supply and grounding review
- Noise and signal troubleshooting
- Component selection and rating checks
- LTspice simulation and circuit verification
- Measurement data and waveform analysis
- Electrical testing and hardware troubleshooting
- Technical documentation and engineering reports
- 2D AutoCAD drafting for engineering applications
I am currently expanding my PCB design capabilities using KiCad through hands-on practice and design review.
My strength is investigating why a circuit does not behave as expected, identifying possible causes from measurements and circuit behavior, and proposing practical engineering improvements.
I focus on clear, practical, and technically grounded engineering work, especially in circuit evaluation, measurement, troubleshooting, and design review.
