Roger Ng Zi Liang
Digital Transformation Analyst and Systems Engineer. I specialize in identifying process bottlenecks and leveraging AI automation, rapid prototyping, and systems thinking to deploy real-world solutions.
About
Who I am
Bridging the gap between physical operations and digital workflows. With a foundation in Robotics Systems Engineering, I approach business bottlenecks through a systems lens—breaking down complex problems into scalable, automatable steps. I translate stakeholder needs into governed digital delivery (workflows, integrations, and applications), applying the same rigorous standards to software as I do to hardware requirements, documentation, and user training.

Career
Experience
From systems internships to digital transformation ownership — shipping governed, documented change that stakeholders can run without heroics.
- Full-Stack Development: Developed user-centric web applications using React for dynamic frontends and Django for robust backends, integrated with PostgreSQL databases to digitize internal business processes.
- Automation & AI Orchestration: Designed and implemented AI-assisted automation workflows utilizing n8n, connecting custom-built web interfaces with automated logic to optimize operational efficiency.
- Lifecycle Management: Applied the Discover–Design–Deploy–Iterate methodology to translate stakeholder business needs into scalable digital solutions, managing the full software development lifecycle (SDLC).
- Infrastructure & Governance: Managed and monitored self-hosted systems and digital infrastructure, ensuring operational reliability and strict compliance with PDPA, Responsible AI, and cybersecurity standards.
- Deployment & Testing: Facilitated end-to-end testing, validation, and deployment of digital applications, providing technical documentation and training to support organizational adoption.
- Mechanical Design & CAD: Designed 5+ engineered systems and contributed to 10+ cross-disciplinary projects, from concept development to fabrication support, applying GD&T and DFM/DFA to ensure manufacturability and design accuracy.
- Assembly & Technical Testing: Executed full mechanical assembly and testing for machines/jigs, working with PLCs, pneumatic systems, sensors, and actuators to resolve functional issues using Sysmac Studio.
- Project Documentation & Procurement: Produced and maintained comprehensive engineering project documentation, including BOMs, Gantt charts, technical drawings, and machine manuals, while managing end-to-end procurement and RFQ tracks for 100+ components.
- Stakeholder Coordination & Support: Conducted on-site machine setup and installation support at customer locations, while facilitating interdepartmental coordination, recording meeting minutes, and aligning team action items.
- Operational Signalling: Served as the primary signaller for missile load/unload operations onto ships, coordinating crane movements, vehicle positioning, and ground crew actions under strict safety and timing protocols.
- Heavy Vehicle Operations: Certified and operated Class 3, Class 4, and forklift vehicles to transport, stage, and position military assets across the sea terminal.
- Process Management: Coordinated high-stakes port logistics and supply chain asset staging, building a strong foundational understanding of physical operational workflows in time-sensitive environments.
- Workflow Automation: Streamlined internal workflows and conducted independent R&D on emerging automation tools using Excel VBA and Microsoft Access, successfully reducing operational lead times by 70%.
- Continuous Process Improvement: Applied root cause analysis to process inefficiencies to implement measurable reliability and stability upgrades across cross-functional teams, earning a Certificate of Appreciation.
- Standardization & Onboarding: Authored and developed standardized training documentation to improve onboarding consistency and systematically reduce operational process variability.
- Operational Empathy & Process Awareness: Navigated ground-level logistics, retail, and F&B environments, leveraging firsthand understanding of physical workflows to design highly user-friendly digital transformations.
- Rapid Problem Solving: Acted as a runner and usher in high-pressure event environments, requiring immediate troubleshooting, spatial awareness, and the ability to adapt to sudden logistical changes.
- Stakeholder Communication: Managed direct customer interactions in sales and F&B, developing the ability to de-escalate conflicts, translate needs quickly, and communicate clearly across different demographic groups.
- Prioritization & Resilience: Successfully balanced ad-hoc employment commitments alongside rigorous academic engineering schedules and mandatory National Service.
