Level G1 · Core Logistics Backend

Feb 2026 - Present

Software Engineer, G1 — Ahamove

Core backend engineer delivering high-scale logistics, order management, partner operations, and financial reconciliation in a nationwide delivery network.

  • Truck Rental Shifts: Architected on-demand vehicle hiring by time and distance blocks (hours + km bundles) with checkpoint visual evidence validation and automated odometer overage billing, unlocking a key corporate B2B logistics revenue stream.
  • Fleet Utilization: Implemented intelligent cancellation restriction windows for pooling orders in IDLE status, protecting driver earnings and preventing vehicle idle fragmentation.
  • Electronic Contracting Platform: Built greenfield econtract service with dynamic legal template generation for Household Businesses (Hộ Kinh Doanh) and Enterprises; engineered secure CMC webhook proxy with audit logging and automated contract renewal.
  • High-Throughput Routing: Migrated legacy routing endpoints to Go for sub-millisecond route evaluations; integrated OpenStreetMap (OSM) real-time toll and ferry pricing lookups to eliminate fare estimation discrepancies.
  • Franchise Partner Portal: Designed internal smart routing and server-to-server (S2S) debt query endpoints for franchise fleet owners; instrumented behavioral analytics via PostHog.
  • Financial Audit & Reconciliation: Decoupled reimbursement payments from standard order revenue and implemented an automated debt sweeping mechanism to eliminate balance leakage.
