Experience

• Built an automated nutrient dosing and electrical conductivity (EC) monitoring system, reducing manual labour by 50% and saving 3+ hours per week through sensor-based control and data logging.
• Developed embedded firmware for ESP32 microcontrollers in C using PlatformIO to interface with sensors, pumps, relays, displays, and user inputs — with cloud logging and configuration via Firebase.
• Designed mechanical fixtures, enclosures, and assembly jigs in Fusion 360, improving assembly efficiency by 20%.
• Created PCB schematics and layouts for new hardware, diagnosing issues related to power integrity, component limits, and signal integrity.

• Spearheaded the implementation of strain gauge sensors to assess electromechanical behaviour, devising application-specific Wheatstone bridge circuits (quarter, half, or full bridge) accurate to ±5με while compensating for disturbances and cross-sensitivities.
• Developed and executed validation test plans — thermals, water ingress, single fault, and more — using sources, loads, thermocouples, and dataloggers to ensure system reliability.
• Automated data graphing using Python, reducing manual processing time by 80%.
• Led implementation of humidity sensors and built custom miniature humidity probes for installation in tight volumes.
• Diagnosed and resolved root causes using LTspice simulation, oscilloscope signal analysis, and hands-on circuit modification — soldering and reflow for SMD components.
• Programmed in C to replicate charger operation for focused verification tests.

Embedded design with two early-stage startups, Verdi and Takachar, providing mechatronics expertise in an agile, fast-moving environment.

• Verdi — Led development of an adapter to read soil moisture sensors and output an analog voltage using an ATtiny85 microcontroller, op-amp, 555-timer, and passive components — 53% cost savings versus proprietary options.
• Verdi — Programmed a calibration GUI in Python and 3D-printed a calibration jig, reducing calibration time by 83%.
• Takachar — Designed a high-current analog fan controller PCB in Altium, capable of reliably driving four 70W fans.
• Takachar — Verified theoretical PWM frequency with LTspice simulation, then confirmed actual frequency on an oscilloscope.

• Modeled, procured, and assembled a 35 ft² electrical panel for an electron-beam additive manufacturing machine.
• Implemented GD&T (ASME Y14.5) and ISO standards to produce manufacturing drawings.
• Designed three XYZ gantry motion concepts in Onshape using ball screws, linear rails, and timing belts.
• Optimized stress and deflection using static and thermomechanical FEA simulations in SimScale.
