4 ปี 5 เดือน IoT Architecture Team Leader Strategic System Architecture: • Architected a robust IT/OT infrastructure for a Centralized Monitoring Platform & Smart Data Center, enabling real-time analytics for plant performance optimization. • Network Topology: Designed end-to-end network connectivity utilizing diverse ISPs (Fiber/4G/5G/FWA) and secured with Site-to-Site VPN, NAT Traversal, and complex WAN/LAN IP structuring to ensure seamless remote access. • IoT & Protocol Integration: Configured Siemens IoT2050 controllers and integrated multi-protocol devices (Inverters, Meters, Sensors) via TCP/IP, Modbus RTU, RS485/232, Profibus, and IO-Link. • Physical Layer Design: Selected optimal cabling solutions (Fiber Optic, LAN,RS485) based on site environment and distance. Designed AI-ready CCTV systems with high-bandwidth cabling to support future Image Processing and advanced security. • Power & Reliability: Calculated power consumption loads to design Power Redundancy Systems (UPS) and industrial Surge Protection, ensuring zero downtime during power outages or electrical surges. Smart Solutions & Business Value: • Auto-Billing Ecosystem: Pioneered the "Smart Metering & Auto-Billing" solution, enabling real-time online data retrieval. This initiative eliminated the need for manual on-site meter readings nationwide, significantly reducing operational costs and man-hours. Project Management & Execution: • Manage EPC & contractors and vendors, conducting rigorous inspections to ensure installation compliance with engineering designs. • Project Delivery: Managed the full project lifecycle from Test Run, COD , ensuring all projects were delivered on schedule. Leadership & Operations: • Team Management: Led the technical team by providing expert guidance, remote troubleshooting support, and organizing training programs to upskill team members. • Budgeting: Managed the annual budget for IT/OT equipment and communication systems, optimizing costs while maintaining technical standards. Senior communication system engineer เมษายน 2023 - เมษายน 2024 (1 ปี 1 เดือน)

Acting as a Lead Developer and Technical Consultant for utility-scale solar farm projects (5-10 MW), bridging the gap between engineering, regulatory compliance, and business operations. Strategic Project Development: •Successfully managed project development under government schemes including (2024)Feed-in Tariff (FiT) (2025/26) "Quick BIG Win". •Secured Power Purchase Agreements (PPA) and coordinated complex grid interconnection requirements with PEA and EGAT. Licensing & Regulatory Compliance: •Navigated complex regulatory landscapes to secure critical permits, including Construction Permits (Or.1) and Factory Licenses (Ror.Ng.4 - number 88). •Liaised directly with the ERC (OERC) and local authorities to ensure full compliance. Technical Audit & Asset Handover: •Led the "Taking Over" process from EPC contractors, conducting technical audits on Inverters, PV panels, and BOS. •Validated Performance Ratio (PR) and installation quality to ensure assets met engineering standards before COD. Site Feasibility: •Conducted technical and geographical assessments for potential solar sites to ensure grid connection viability and land utilization.
