Experience & Projects
A journey through my professional experience and personal projects that showcase my growth as a developer
Automation & Digitalization
System Engineer
Deployed 3-layer architecture for factory-wide anomaly detection, reducing logistic bottleneck latency by 24%. Implemented predictive routing with queuing theory over 100K+ datapoints, preventing multimillion-IDR losses.

1st Place Roboboat 2025
Electrical Systems Engineer
Led power and comms platform in “Nala Ares”. Achieved 90% mission continuity under fault-injected scenarios.

Personal Finance Management Platform
Full-Stack Engineer
Engineered a personal financial dashboard with real-time income–expense tracking, trading-style visualizations, and category-based analytics. Optimized for responsive UX with secure data flow and interactive infographics.

APU Control System
Electrical Engineer
Design anomaly detection, and system health analytics (APU).
Systems Engineer
Fault Injection & Synchronization
Executed actuator–logic synchronization for 34 autonomous units. Injected multistate fault modes to validate system recovery across 7 operational anomalies.

Seismic Structural Monitoring
Seismic Systems Engineer
Deployed 5Hz SHM nodes with DKF + fuzzy logic fusion. Captured subthreshold tremors for early warning systems under real-world deployment scenarios.

3rd Place Roboboat 2024
Electrical Designer
Engineered fault-tolerant system fallback during electromagnetic interference for “Nala Proteus V2”.

PKM-KC | Underwater Autonomous Vehicle (UAV)
Electrical Designer
Designed core electrical architecture for autonomous underwater vehicle under PKM research scheme. Integrated sensor–power stack with modular communication logic for mission adaptability and waterproof performance testing.

CCTV Thermal HVAC
Embedded Systems Developer
Developed a thermal-vision-based HVAC automation system with CCTV integration. Engineered embedded control logic to detect occupancy and trigger ventilation via real-time temperature maps, enhancing energy efficiency and safety.
Electrical Systems Engineer
Control & Power Architect
Engineered dual-band communication and telemetry fallback across offshore control systems. Achieved 89% signal integrity and energy resilience in high-volatility sea-state operations.

Electrical Design Engineer
Autonomy Stack Developer
Built power-sensor telemetry stack for hydro-oceanographic USVs. Validated sensor rerouting logic under current-induced turbulence in coastal deployments.

1st Place Roboboat 2023
Electrical Designer
Built error-correcting embedded logic for “Nala Proteus”, fusing real-time sensor inputs for robot resilience.

1st Place KKCTBN 2023
Electrical Designer
Built power-control stack for “Nala Athena”, reducing power loss by 90% in USV missions.

Teaching Assistant
Mentor & Evaluator
Mentored 100+ national developers, evaluated 50+ systems for viability and UX quality, and embedded real-time feedback into code pipelines.
