We need a Senior .NET Backend Engineer Consultant (AI-Forward) to build the APIs at the center of a pharmacy platform. Prescription and claims data pass through the services you’ll own. You understand pharmacy workflows well enough to know why a controlled-substance refill, a transfer and a prior-auth denial each need different handling. This is a corp-to-corp, 1099 engagement for an independent consultant who works autonomously and uses AI tools daily to multiply their impact.

Key Requirements

• 10+ Years of C# / .NET
• ASP.NET Core Web APIs on current .NET, EF Core and Dapper.
• Clean, testable service design: idempotency, resilience, observability; unit, integration and end-to-end tests.
• SQL Server
• Strong SQL, including working confidently inside large existing schemas.
• Azure
• Key Vault, Storage, Application Insights, managed identity, containers.
• Securing services with Entra ID; CI/CD (GitLab, GitHub or Azure DevOps).
• Pharmacy Software (Required, 3+ years)
• Building software for a pharmacy or PBM: prescription lifecycle, NCPDP claims, NDCs and drug data, NPI and DEA, refill and transfer rules, controlled-substance handling.
• Experience with HIPAA-regulated systems and PHI.
• AI-Forward Engineering
• Daily practitioner with AI coding tools and agents: Claude Code, OpenAI Codex CLI, GitHub Copilot or Cursor.
• Prompt and instruction design: translate business rules into structured prompts, tools and context.
• Code review and output evaluation with a human in the loop; you own what ships., Experience: C# / .NET, 10+ years (required); pharmacy or PBM software, 3+ years (required)

• Your resume or consultant profile highlighting .NET, SQL Server and pharmacy or PBM software work.
• A short note on your LLC or S-Corp (name, state).
• Links to relevant work (APIs, write-ups, demos or repos).
• 3-5 lines on how you use AI tools (Claude Code, Codex CLI, etc.) to accelerate delivery while keeping PHI safe.

Optional (helps us fast-track you): answer in 1-2 sentences each.

• What has to be true before a pharmacy can fill a faxed Schedule II prescription?
• A claim rejects, then a corrected claim is submitted. How do you design the reversal and retry path so nothing is double-billed?
