Jan 2026 – Present

Research Assistant, University of Texas at Austin· Austin, TX

Architected C++ firmware on Raspberry Pi Pico to synchronize 16-DOF bionic hand kinematics from remote glove telemetry, achieving 1ms sensor-to-actuation latency.
Tuned PID control loops for 10 independent joints, improving tracking from unreliable to consistently stable real-time replication across the full range of hand motion.

Jun 2025 – Aug 2025

Embedded Systems Intern· Houston, TX

Replaced $20K/site legacy PLC/Modbus installations with a custom nRF9160 board under $250 (98% cost reduction), deployed across 50 field units within a $5K R&D budget.
Engineered C/Zephyr RTOS firmware for LTE-M + GNSS over a 40-node LoRa mesh to AWS IoT Core; wrote a safe-shutdown handshake preventing LTE tower rejection on power cycle.
Automated TLS certificate provisioning via Python + AT%CMNG, reducing per-unit onboarding from hours to under one minute across all deployed units.
Led full product lifecycle — KiCad PCB layout, Fusion 360 enclosure, firmware dev, and field validation — delivering production-ready hardware under budget.

Jun 2022 – Jul 2022

Software Engineering Intern· Houston, TX

Built a Spring Boot/Cassandra microservice for a 2M+ record keyspace; optimized SQL logic reducing latency by 40%.

Jun 2023 – Aug 2023

Computer Science Research Intern· Houston, TX

Built Python data-visualization tools to render multi-gigabyte CFD vortex datasets — 3D volumetric view, hierarchical tree views, scatterplots, time-series line graphs — supporting a graduate research team on coherent-structure extraction; credited on the NSF project webpage.

C++ · ESP32 · FreeRTOS

Wrote a C++ flight controller on ESP32 running a 1.0ms PID attitude loop, measured at 45µs of jitter using GPIO toggling captured on a Saleae logic analyzer.
Implemented I²C sensor fusion pipeline reading MPU-6050 IMU, driving four motors via 400Hz PWM — stable hover within ±2.5° over 60-second tests.
Built a custom ESP-NOW telemetry layer for low-overhead controller-to-drone communication.
