Experience with modern state management (Redux/Zustand) and Tailwind CSS

Backend:

Deep proficiency in C# and .NET 10/Core.
Experience with Entity Framework Core and high-performance API design.

AI/GenAI:

Proven experience with LLMs (4th generation or newer), Prompt Engineering, and building RAG applications.
Familiarity with LangChain or Semantic Kernel is a plus.

Cloud

Strong experience with Azure (App Services, AI Search, Key Vault) and Azure DevOps/GitHub Actions for CI/CD.

Database

Advanced PostgreSQL skills, including schema design, performance tuning, and NoSQL (CosmosDB) experience.

Preferred Skills:

Experience with AI / GenAI concepts, including LLMs, prompt engineering, or Retrieval-Augmented Generation (RAG) patterns
Familiarity with Azure OpenAI Services, LangChain, Semantic Kernel, or similar frameworks
Experience with containerization and orchestration (Docker, Kubernetes)
Exposure to NoSQL databases such as Cosmos DB
Understanding of secure coding practices and regulated data environments

Required Experience:

7+ years of professional software development experience
At least 3 years operating in a Senior or Lead Engineer capacity
Hands-on experience building and supporting production-grade, cloud-native applications
Experience collaborating with distributed or offshore development teams

Preferred Experience:

FinTech, lending, or financial services platform development
Building or modernizing partner portals or external-facing systems
Greenfield development of enterprise platforms
Platforms that have evolved to incorporate AI-assisted workflows

Education:

Bachelor's degree in Computer Science, Software Engineering, Information Systems, or related field required
