Experience

Worked on assigned modules inside the H2ALL / FastLink enterprise ERP/logistics platform, focusing on finance-related workflows, import operations, reporting, data reconciliation, and backend-oriented tracing across WinForms clients and hybrid service flows.

• Owned logic in import finance and reporting workflows, including detailed debt reports, beginning-balance handling, import fee processing, and debt-collection handoff support.
• Improved legacy import debt reconciliation by refining business-key mapping, beginning-balance logic, and cross-source consistency to strengthen reporting accuracy and maintainability.
• Supported production changes in workflow-heavy modules and traced issues end to end across UI -> service wrapper -> handler -> business logic -> data layer -> database to validate business rules and improve maintainability.
• Improved heavy report and search flows handling 30k+ rows, contributing to ~40% faster report runtime and ~30% lower DB/query cost in supported areas.

Early backend foundation in enterprise application support, focused on maintaining backend modules and API-related flows.

• Supported production-safe changes in ASP.NET Core backend modules and endpoints, including validation updates, bug fixing, defect investigation, and logging-related improvements.
• Worked with teammates on API enhancements, testing support, and query review to help keep backend changes stable and release-ready.
