Featured Projects

Finance Control API

Personal finance management REST API built in C#/.NET with PostgreSQL, Entity Framework, and FluentValidation. Clean Architecture. Mobile frontend in Flutter (in development).

Parallel Computing Performance Analysis

Benchmarking distributed vs. single-machine data processing with Apache Spark on a multi-node AWS EC2 cluster. Implemented in Python, Pandas, and NumPy.

Professional Highlights

  • Built the Centralized Payment System (SLC): an automated pipeline that extracts transaction records, transforms them into structured payment files, and delivers them via Azure Blob Storage and SFTP to the payment processor; replaced a 5-hour daily manual process
  • Built the Billing Management System (GCB) as sole developer, automating charge calculation and chargeback processing across multiple billing categories
  • Developed customer-facing portal features in TypeScript and React for a platform used by clients and internal operations teams
