My Work Experience

Where I've interned and worked during my career.

Teletouch Communication | Dec 2023 - Present

Backend Developer

Led backend architecture for two key modules using ASP.NET Core and SQL Server, building scalable APIs and normalized databases to support 1K+ users/month. Assisted in SQL Server to Azure SQL migration, performing PoC, schema testing, and tuning, supporting the foundation for cloud-based analytics. Simulated real-world traffic using JMeter and Azure Load Testing to ensure that APIs and data endpoints could handle 5,000+ concurrent users without loss. Engineered API logging infrastructure in .NET to trace and mitigate abnormal request patterns, reducing noise by 90% and improving observability for downstream data collection. Resolved distributed messaging bottlenecks by integrating SignalR with Redis, enabling real-time events across IIS workers — a key step in building a high-throughput data push model. Optimized report export processes by refactoring SQL logic and implementing reusable query components, contributing to faster delivery for BI and user-facing reports. Reduced long-running operations in data-heavy workflows by up to 90%, using methodical profiling to isolate expensive loops and deadlock-prone section
