I built scalable backend applications at Semantha Technologies using C#, .NET, SQL Server, ADO.NET, and Entity Framework. I also improved database execution speed by approximately 25–30% by refactoring Entity Framework implementations to ADO.NET.

I architected backend microservices integrated with AI/LLM pipelines for automated data extraction and intelligent workflow processing. As an AI Training Contributor, I develop and evaluate software engineering datasets, algorithmic benchmarks, edge cases, and system architecture problems for LLMs.

I designed the backend for a Driving and Vehicle License Department ecosystem supporting Desktop, Web, and Mobile applications through centralized ASP.NET Core services and shared business logic. I also integrated AI-powered OCR for national ID extraction and verification and built real-time notifications using the Publisher-Subscriber pattern.

I develop cross-platform mobile services with Flutter, Dart, and REST APIs, including licensing applications, detention payments, document verification, notifications, and backend synchronization. My work is grounded in clean architecture, SOLID principles, maintainability, scalability, and long-term system design.
