About
I am a PhD-qualified Research and Development Engineer specializing in electronics design, scientific instrumentation, sensor systems, embedded electronics, and automated measurement solutions.
My expertise includes electronic circuit design, PCB development using Altium Designer, prototype development, sensor interfacing, laboratory automation, and Python-based data acquisition and analysis.
I have designed and developed multiple scientific and engineering instruments, including:
- Multifunctional liquid analysis instruments for density, surface tension, electrical conductivity, and permittivity measurement.
- Automated specific surface area measurement systems based on the BET technique.
- Electronic air purification systems incorporating electric fields and UV technology.
- Automobile emission purification prototypes.
- Sensor-based systems for environmental monitoring and chemical analysis.
I also have hands-on experience in troubleshooting, repairing, and restoring complex laboratory equipment, including high-voltage electronics and scientific instruments.
**Services I can provide:**
- Electronic circuit and PCB design
- Sensor integration and measurement systems
- Scientific instrument development
- Python automation and data acquisition
- Embedded electronics and hardware prototyping
- Product research, feasibility analysis, and proof-of-concept development
- Electronic system troubleshooting and technical documentation
I focus on reliable, cost-effective, innovative engineering solutions and enjoy transforming technical ideas into functional prototypes.
