Work Experience

Software Engineer Intern at Binarindo Pratama

January 1, 2026 - June 30, 2026

Collaborated with stakeholders to gather requirements and define user flows for a full stack ERP (sales distribution, HR attendance/payroll) and B2C e-commerce, shipping features adopted for daily operations. Architected a fault-tolerant offline-first push-pull data synchronization engine on .NET 8.0 Minimal APIs using a three-layer service design for reliability over unreliable networks. Designed and integrated RESTful APIs exchanging JSON payloads across web, mobile, and backend services. Built an offline-first Flutter mobile app (CLEAN Architecture) with secure authentication, GPS coordinate validation, and background processing. Tested, debugged, and optimized deployed systems in live environments, tracing sync pipeline failures to root cause and applying retry logic to ensure reliable data delivery. Produced technical documentation and supported ongoing maintenance through disciplined SDLC and Git/GitHub-based code review.
