Need a backend that ships and stays up, plus a frontend your users actually want to use? That is the work I do. I own the whole thing: architecture, REST and GraphQL APIs, multi-tenant data, payments, real-time, cloud, and CI/CD, including the reliability work most people skip. I build systems that hold under real load, not prototypes that break in week two. Systems I designed and built: RoverDent, a multi-tenant dental and healthcare SaaS. Nine .NET 8 microservices behind a React 18 dashboard, with Temporal running multi-day patient follow-up so call, SMS, email, and WhatsApp sequences never lose state. Two services are Python FastAPI: a LiveKit real-time voice AI agent, and a conversation API doing AWS Cognito RS256 token verification and WebSocket chat. Stripe and Twilio in production, HIPAA-aware audit trails, field-level isolation and RBAC across tenants. VisionONE, an enterprise ERP and payroll platform. .NET 8 with a dual-ORM strategy: EF Core for the domain model and Dapper for heavy accounting and ledger queries where read performance matters.
