About

Electrical engineering graduate (GPA 3.67/4.00) in robotics, embedded systems, and mechanical design. Owned a quadruped robot’s autonomous navigation for my thesis (ROS 2, Nav2, LiDAR SLAM, MPC), built a heavy-equipment motor test rig end to end as an intern, and design parametric assemblies in Autodesk Inventor. Three years each of olympiad coaching and copywriting. Remote-ready, async-first, and flexible on hours for US, EU, or APAC overlap.

Experience

Junior / System Study Engineer PT Ilamos Pasifik Indonesia · Internship Jun 2025 – Aug 2025 2 mos Jl. Krekot Bunder Raya No.47AB, RT.4/RW.6, Ps. Baru, Kecamatan Sawah Besar, Kota Jakarta Pusat, Daerah Khusus Ibukota Jakarta 10710 • Designed the drive circuit and wrote the control and measurement firmware for a heavy-equipment (excavator) stepper-motor test rig, then assembled and commissioned the unit.
• Produced the 2D/3D technical drawings for the rig’s components and assembly using Inventor

Education

Calvin Institute of Technology B.Eng., Electrical Engineering, 3.67 2022 – 2026

Other experience

TECHNICAL PROJECTS Machine Learning Course Projects 2025
• News summarization (team): ran the PEGASUS fine-tuning track with Hugging Face and Weights & Biases; the best of three runs scored ROUGE-1/2/L 39.6/19.1/29.8 on CNN/DailyMail, nearly 10 ROUGE-1 points above the first.
• Face recognition: built a pipeline from OpenCV face capture to four scikit-learn classifiers tuned by grid search and stratified cross-validation, and documented why same-session test data overstates accuracy.
TECHNICAL PROJECTS Mechanical Design Portfolio — Autodesk Inventor
• Four parametric assemblies modeled down to their internals: Strider, a 1.1 m quadruped; Pivot, its harmonic-drive actuator (frameless motor, cross-roller bearing); Pip, a 72 mm desk robot; Beacon, a sealed 18650 flashlight.
AWARDS & LEADERSHIP • Gold Medal, National Science Olympiad (OSN) — Social Sciences, Indonesia, 2018
• Bronze Medal, OSN — Geography, 2021
• President, Electrical Engineering Student Association (HIMAPRODI IEE), 2024 – 2025
• President, Calvin Debate Society, 2024
• Participant, GEMASTIK & PKM national competitions, 2023
EXPERIENCE Engineering Intern — PT Ilamos Pasifik Indonesia Jun – Aug 2025
• Designed the drive circuit and wrote the control and measurement firmware (C/C++) for an excavator stepper-motor test rig, then assembled and commissioned the unit myself.
• Produced the 2D/3D technical drawings for the rig’s components and assembly in Autodesk Inventor.
Olympiad Trainer — Indonesian Geography Olympiad Alumni Team & partner academies Jul 2023 – Jun 2026
• Coached students for city to national olympiad rounds at 20+ schools and academies in Greater Jakarta and online; wrote original problem sets and trained supervising teachers.
Copywriter — Calvin Institute of Technology Dec 2022 – Dec 2025
• Covered institute news for calvin.ac.id, from interview to published article.
TECHNICAL PROJECTS Rubik’s Cube Solving Robot — Personal Build
• Built and commissioned it from an open-source design (frame, stepper drive, wiring, firmware tuning) and integrated camera color detection with the solver, so it solves a scrambled cube unaided.
TECHNICAL PROJECTS End-to-End IoT Product & System Prototypes — Capstone Coursework 2024 – 2026
• Built IoT prototypes from Arduino and ESP32 firmware and sensors to Node-RED, InfluxDB, and Grafana dashboards in Smart IoT Product Design (A−) and Smart IoT System Design (A).
TECHNICAL PROJECTS AXION: Autonomous Indoor Navigation for a Quadruped Robot (Thesis, graded A−) 2025 – 2026
• Owned the navigation system end to end in a two-person thesis on a DeepRobotics Lite3 Pro: architecture, ROS 2 integration, SLAM, path planning, obstacle avoidance, and all navigation tests (my teammate built the vision side).
• Mapped a campus building with 3D LiDAR and Cartographer SLAM at 2.23% loop-closure error and 0.155 m mean deviation, both within spec; Nav2 A* reached the goal in 10/10 runs, and MPC reacted to new obstacles in 0.23 s.
• Debugged on hardware: fixed yaw integration in the C++ odometry node, added rf2o laser odometry to curb heading drift without an IMU, and resolved AMCL convergence failures and TF race conditions at Nav2 startup.
