watonomous · robotics & ml · humanoid autonomy · design team
oct 2025 – now- trained rl + imitation-learning policies in Isaac Lab + PyTorch, 60+ runs tracked in Weights & Biases; reward-shaping sweeps cut convergence time 40%
- validated the top policies on the physical humanoid: sim → real hardware, not just sim numbers
- wrote the firmware underneath: STM32 FOC motor control + Kalman-filtered IMU/encoder fusion for joint-angle tracking, wired into the ROS 2 control stack
- PCA + inverse-kinematics pipeline on a 21-DOF hand: 15 finger-joint commands → 7 synergy controls, shrinking the policy's action space and giving operators a low-dim teleop interface
einfolab · data engineering co-op
jan 2026 – apr 2026- dockerized python pipeline (pandas + NumPy) ingesting, validating, and reconciling 10k+ records/month across 4 domains (medical, dental, financial, admin), with retries, alerting, and pytest CI
- caught what sql rules missed: scikit-learn Isolation Forest, 92% precision on a labeled validation set
- FastAPI + LLM (structured outputs) auto-classifying flagged errors by type: manual review 2h → 30min at 91% accuracy
- shipped versioned FastAPI endpoints exposing run status, error logs, and record-level audit trails, real-time data-quality visibility for stakeholders
uw formula electric · software & firmware · design team
sep 2025 – apr 2026- live telemetry dashboard (React + Next.js + TypeScript + Tailwind) on Kubernetes with GitHub Actions CI/CD, 5000+ CAN frames per test over WebSocket
- python pipeline (pandas + NumPy) parsing + storing CAN telemetry in TimescaleDB across 30+ tests: post-test analysis hours → minutes
- scikit-learn anomaly model on battery cell telemetry: 94% precision flagging voltage + thermal outliers
- embedded c/c++ firmware for the battery, vehicle control, and power distribution units (BMU / VCU / PDU)
- HIL test rig in c++/python with pytest: simulate sensor faults + CAN dropouts, catch integration bugs before on-vehicle testing
robotics team · embedded systems lead
oct 2023 – jun 2025- designed a six-wheel RC mars rover: ESP32 motor controller, custom chassis, live camera stream over wi-fi
- c++/arduino firmware mapping joystick input to PWM drive + steering signals; 40% improvement in steering repeatability
- fused ultrasonic + IMU + OpenCV for obstacle detection, driving stabilization, and automatic fail-safe stops

say hi
i like talking about systems that move, models that misbehave, and why the sim always lies. if you're hiring for internships, or just want to chat, my inbox is open.
