Software Engineer building scalable .NET backend and React applications with TDD and clean architecture.

What I'm looking for

I want to build scalable .NET/.NET Core systems and React experiences in an agile team—owning architecture, performance, and quality. I’m excited about TDD, DevSecOps, and intelligent AI integrations like RAG pipelines.

I’m a Software Engineer with 3 years of experience building scalable, production-grade applications in .NET ecosystems. I focus on clean architecture, SOLID principles, and TDD to deliver reliable software in agile environments.

At Deloitte, I designed and developed scalable, multi-threaded backend components in .NET, using decoupled Azure Storage Queues to improve fault tolerance and throughput for file scan, image processing, and GenAI workloads. I also optimized SQL Server queries and stored procedures, reducing execution time by 60% and improving system latency.

I strengthen quality and delivery by building Playwright + Cucumber BDD automation frameworks with Allure reporting integrated with Azure Testing Plans. I enforced DevSecOps practices with SonarQube, ESLint security rules, and SAST tooling, and I refactored legacy UI and backend components to reduce technical debt.

I’ve also built production RAG pipelines using Azure OpenAI (GPT-4o), LangChain, and Azure AI Search for intelligent ESG scope recommendations, significantly reducing manual scoping effort. Alongside Azure Document Intelligence for automated extraction and semantic chunking, I’ve worked to turn complex regulatory data into usable, actionable outputs.
