Bhavesh is an award-winning developer with a strong foundation in math and electronics. His professional experience includes end-to-end embedded software development and hardware design. His code runs on SpaceRyde's gondola and rocket, McMaster University's launched satellite, Quanta Vici's Bluetooth gloves, and Ecobee's IoT lightswitch. These projects are on embedded Linux and microcontrollers (both bare metal and RTOS) and are written in C, C++, and Python.

Work Experience


2022 - 2023
  • Built, tested, and deployed the MVP hardware, firmware, and enclosure for a camera-based, battery-powered, LTE-connected smart meter reader in just one month. Used ESP32, MicroPython, and Fusion 360.
  • Built and deployed V2 magnetoresistive smart meter readers to our existing customers to give them a 15x improvement in time granularity and a 500x improvement in measurement precision compared to the V1 camera-based hardware.
  • Developed a Python and Flask MVP back end for ingesting the smart meter's images.
  • Acquired two paying customers for our smart meter reader and built two ruggedized and weather-proof versions of our device to deploy on-site at their buildings.
  • Developed a V2 back end in Python and Django to increase development speed and leverage the Django ecosystem (e.g., ORM, user authentication, cron jobs, and Django-ninja API).
  • Visualized our deployed IoT devices' metrics on our internal dashboard using Grafana.
  • Built the MVP of our building energy data analytics solution using Python, Pandas, Streamlit, Plotly, and Firebase.
  • Launched the MVP of our building energy data analytics SaaS to 40 beta users. Conducted user interviews with them to gain feedback and improved the software with major feature launches every week.
  • Built a landing page and email intake form to launch our smart meter reader and analytics software to the broader market.
  • Interviewed, hired, and managed a design consultant to develop our outreach materials, including a one-page explainer, investor pitch deck, and brand color scheme.

Edge AI Pipeline Optimization Consultant

2022 - 2022
  • Moved CPU-intensive image transformation functions to run on the GPU instead and further optimized the video pipeline using multi-threading, thus improving the runtime speed of the video inference engine by 2x.
  • Identified the cause of a critical memory leak that caused the video inference engine to crash every two hours on a target with 64GB RAM. With my fix, the inference engine only needed 12GB RAM in total during the app's lifetime—a 5x reduction.
  • Profiled the AI video pipeline using the Python profiling tools Memray (for RAM optimization) and Pyinstrument (for CPU optimization).

Embedded Software Developer

2021 - 2022
Schneider Electric
  • Developed the communications logic between Schneider Electric's solar inverters and the smart grid protocol IEEE 2030.5, using embedded C.
  • Wrote and tested the end-to-end system for correctness using Gherkin and the BDD methodology.
  • Ran IEEE 2030.5 compliance tests (60 of them) on the whole system, in order to submit the test results for official certification.
  • Recorded training videos to document the IEEE 2030.5 code modules and processes for my team members.
  • Created a Jira page with architecture diagrams and documentation of the IEEE 2030.5 code modules.

Quanta Vici
  • Refactored the (pre-existing) messy implementation of Bluetooth (BLE) logic for an IoT heated glove product resulting in greatly improved code reliability.
  • Architected a state-based design to ensure the smooth integration of NFC, Bluetooth (BLE), and sleep and wake features.
  • Wrote Python scripts to automate the firmware build process and device flashing process for manufacturing.

Near-space Balloon Launch Mission - "Apollo 19"
I led a team of five to design, test, handle operations, launch, and recover a stratospheric balloon with an Ecobee thermostat as the payload. My role was central to fulfilling this amazing shared mission and included these activities:

• Marketed the project to the company.
• Got buy-in from senior management.
• Crowdfunded its development.
• Managed the team of three Ecobee volunteer engineers.
• Liaised with an ex-NASA space scientist for mission support.
• Procured all the materials.
• Simulated the flight path based on wind conditions and chose an ideal launch site and date.
• Led the launch and recovery team on the day of the mission.

Sign Language Translation Glove
I designed the hardware, wrote the firmware, and designed the GUI, 3D animation (OpenGL), and machine learning (SVM) software for a sign language translation glove for my final-year capstone project at McMaster University. We received the 1st place award for best project in the electrical and biomedical engineering department for our accomplishment.

PCB Design for a Bluetooth Gesture Glove
I designed the PCB for a prototype glove that can capture the wearer's movements and gestures and transmit the data over Bluetooth. The project was built upon the proof of concept foundation of my university capstone project (Sign Language Translation Glove) in order to miniaturize the design and make it ready for mass manufacturing.
