Smart Metering Grid Project ● System Monitoring and Troubleshooting: proactively identifying anomalies and swiftly resolving technical issues to minimize downtime and enhance system reliability. The process involves conducting a hardware inspection of both wired and wireless LAN and WAN systems, as well as component checks. Design the parameters and create tools to convert the signal from the PCB inside the network gateways, IO modules, switching, and server infrastructure into digitized data such as Tx, Rx, RSSI, and system connectivity reliability. Use Wireshark and Zabbix to monitor the traffic from both system- and server-side devices. Create automated machine Python scripts to detect anomalies and visualize them throughout the graphs, reports, and dashboard. ● Create the development environment with virtual machines (VMware or MobaXTerm) and Docker containers. Design, control the testing environment, and conduct the testing criteria (Soak Testing, SAT, FAT, etc.). As part of the Data Connectivity/Disaster Recovery (DC/DR) safety procedure, execute the migration to production. ● Data Governance and Validation: Created and implemented a data pipeline and ETL acquisition to ensure data accuracy and validation within smart metering infrastructures. I utilized computer languages such as Python, C, and Java to inject, extract, and visualize data integrity. Develop on-demand software and applications that are compatible with every operating system (windows, MacOS, Linux, and mobile applications such as iOS and Android) for data injection, validation, anomaly detection, system monitoring, and visualization with a real-time dashboard and report generation.

● Pursue identified automation responsibility area projects, maintenance, and operation throughout the Thailand region, applying the tools and methodologies being utilized by the company and division-wide.  ● Strategies setting with key customers for marketing protection with agreement contact, i.e., O&G, Upstream, Midstream, Refinery, Power, and Hybrid markets. Pursued and negotiated contract pricing and T&C for key projects that are of strategic importance to the organization. ● Interacted across all levels with managers, marketing development, the service specialist, the service engineer, the sales support team, and administrators within the division in Asia Pacific. ● Communicated courteously with current and new leads by site visitation, online, and in real time.  ● Developed and implemented projects after obtaining customer purchase orders by coordinating procurement with factories and communicating efficiently to finish them according to the project execution strategy. To keep consumers updated, provided accurate timelines.

Business Development: I defined a win-win partnership strategy and established a partnership.with customers’s companies to co-create new projects, enhanced data analysis, and integrated technology into business processes. Increased market share by creating maintaining and expanding relationships with key trade clients, distributors, and wholesalers. ● Established an entire organization that adheres to a systematic and organized workflow. ● Conducted a study of the market and subsequently integrate the sales strategy into motion. ● Coordinated with field engineers, the project manager, and quality assurance to achieve the highest level of customer satisfaction possible by acclimating the company's services to client needs and promptly resolving any quality-related issues.

Field Instrument Specialist: Responsible for commissioning and training at the project site, conducted root cause analyses, risk assessments, incident investigations, and identified problematic components and replacing them with new components and assemblies onsite. ● Assessed item and service quotations, including shop drawings and specifications, and offered customer support.  ● To get orders, we gave post-RFQ "technical bid evaluations" and "post-tender explanations." Coordinated field workers and EPCs/contractors to ensure project quotes met end-user standards. When necessary, management grants authority to assure consumer satisfactions. ● Developed and implemented projects after obtaining customer purchase orders by coordinating procurement with factories and communicating efficiently to finish them. according to the project execution strategy. To keep consumers updated, provide accurate timelines. ● Evaluated design adjustments during the order phase and arranged factory inspections when The order was complete. ● Resolved post-order technical and quality issues. ● In addition to manage post-order deliverables between clients and other parties, post-order documentation, e.g., project evaluation (covering technical, risk, cost, etc.).

● Performed pre-installation, provided technical direction for the implementation of projects, and finalized the installation of field instruments. ● Was responsible for project site commissioning and training. ● Provided technical support by email, phone, or onsite (countrywide). ● Provided feedback on products to the sales and marketing teams. ● Conducted root cause analysis, risk assessments, and incident investigations through root cause analysis, identified faulty components. ● Performed replacement of components on site with new components and assemblies onsite. ● Logged and documented all issues in our tracking system. ● Worked with partners to troubleshoot and resolve issues.
