At Pan Asia Resources, I optimized a logistics application’s C# logic and SQL queries, reducing peak CPU utilization from 100% to under 60% and eliminating recurring peak-hour slowdowns. I also developed REST APIs and integrated payment gateway workflows.
At Cordlife Indonesia, I built a Power Apps Canvas application from scratch for field teams to manage customer information on mobile devices, including offline data collection and synchronization. I also developed Dynamics 365 integrations and Power Automate flows.
At Maltem Asia Pacific, I developed a C#/.NET Worker Service to validate SWIFT messages and store validated data in Amazon S3. I also created Python workflows and Apache Airflow DAGs for downstream data processing.
At PT.Epson Batam, I built and enhanced a multi-module General Office System and developed RFID warehouse solutions that accelerated transfer processing by 35%. I also designed n-tier applications, led teams of more than 10 members, and contributed to manufacturing, HR, payroll, and business intelligence systems.
