Hi, I have gone through your AI / ML project for the Retail Chain. It looks straightforward at first, but integrating Azure OpenAI with .NET APIs, SQL databases, and cloud infrastructure requires careful planning around data flow, security, scalability, and maintainability. I can outline a practical approach for you. I have over 10 years of experience in .NET, SQL, cloud computing, Azure, database administration, software development, database development, and API integration, and I'm excited to be part of your project. Let's discuss your Retail Chain requirements in the chat so I can recommend the most practical and cost-effective Azure OpenAI solution. ~ Rajesh

Hi! I read that you're looking to convert a Mainframe DB2 legacy application into a modern Azure-based application, using APIs and Azure Key Vault for secure credential management. I have 8+ years of real-time IT experience with .NET, SQL, and Azure, including building and deploying secure, API-driven applications across multi-tenant SaaS, healthcare, e-commerce, and hospital management platforms. I'm comfortable working with Azure DevOps for CI/CD, Azure Key Vault for secrets management, and designing REST APIs that bridge legacy data sources with modern cloud architecture. For legacy-to-cloud migrations, I focus on mapping the existing DB2 schema and business logic carefully first, then building a clean, well-tested API layer so nothing breaks during cutover. I'd like to understand a bit more about the current DB2 setup and whether data migration, API-only integration, or a full rebuild is expected, so I can scope this accurately. Let's connect to discuss details and timeline. Akshay B

I have solid experience working on backend modernization projects involving legacy systems, API integration, cloud migration, and scalable service architecture. Your project requires more than a direct DB2 migration — it needs careful restructuring of business flows, secure API exposure, and reliable Azure integration to avoid performance and maintenance issues later. My approach would be to first map the existing DB2 workflows and identify domain boundaries that can be exposed through APIs or separated into independent services. From there, I can help structure a migration path using Azure services, secure secret management with Azure Key Vault, and a maintainable API layer integrated with SQL-based persistence. I also have strong experience with distributed systems, cloud infrastructure, asynchronous processing, and high-availability backend applications, which is important when replacing legacy enterprise environments. I can contribute on architecture decisions, API implementation, database transition strategy, performance optimization, and integration workflows. I am comfortable collaborating with existing teams, reviewing legacy logic, and delivering incremental migration steps instead of risky full replacements. Available for ongoing hourly engagement and technical discussions as the project evolves.
