• Developing custom firmware for the nRF52 platform (based on Nordic SDK) as a replacement for prior OTS software, coinciding with the nRF51 hardware migration.
• Supporting the selection process and porting software for the transition from an end-of-life (EOL) 16-bit TI MSP430 MCU to a modern STM32U0 MCU.
• Evaluating and integrating an SPI-interfaced micropower differential angle sensor to enhance motor control precision.

Security Implementation & Cybersecurity Assurance

Integrated the Bluetooth Authorization Control Service (ACS) using X.509 certificates within an Identity and Access Management (IAM) framework, applying AES-based encryption on the application layer, to ensure Secure Plug & Play Interoperability for Automated Insulin Delivery (AID) devices. Provided comprehensive support during Cybersecurity Assessments (including Penetration Testing) conducted by the Fraunhofer Institute for Secure Information Technology (SIT), which involved providing test devices/documentation/information, addressing assessment team questions, and participating in the discussion/remediation of findings, contributing to the successful attestation

Regulatory Documentation & Support

Contributed technical documentation and support for regulatory submissions and certifications, including FDA premarket submissions, CE marking technical files, and IECEE CB Scheme reports.

Bluetooth Standardization & Qualification

Actively participated in the Bluetooth Low Energy standardization of Insulin Delivery Service (IDS) and Authorization Control Service (ACS) by engaging in technical discussions, developing prototypes and actively executing interoperability tests during IOP events. Played a key role in the Bluetooth Low Energy (BLE) qualification of multiple products, with responsibilities including performing tests using the Profile Tuning Suite (PTS), documenting rationales for necessary waivers/deviations, and serving as the technical liaison with the Qualification Consultant (BQE).
