Senior full-stack engineer building production SaaS platforms and AI-driven backends. .NET, C#, ASP.NET Core, Python, FastAPI, Node.js, Angular, React, TypeScript. 9+ years, Top Rated, 100% Job Success. 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. Angular 20 frontend with NgRx and AG Grid Enterprise for data-dense payroll views. Real-money disbursement through Lipa Na M-Pesa STK Push with webhook callbacks and transaction-status polling, so payment state stays correct end to end. Hangfire for background salary runs, TOTP two-factor auth across multiple SQL Server databases. SmartStay, a multi-tenant hotel and property management SaaS. ASP.NET Core 8 on the ABP framework with an Angular 17 front end. Stripe and PayPal behind PCI-ready Azure infrastructure (VNet, WAF, NSG), SignalR pushing live room-status and reservation updates, GraphQL for flexible queries, Redis caching, and Power BI dashboards for managers. What I help clients build: Multi-tenant SaaS with RBAC, tenant isolation, and secure architecture REST and GraphQL APIs, microservices, CQRS, clean architecture Modern frontends: Angular (NgRx, AG Grid), React, TypeScript, responsive UIs Payments and billing: Stripe, PayPal, Authorize.Net, M-Pesa, webhook handling and signature verification Real-time features: SignalR, WebSockets, MQTT, event-driven backends AI and LLM integration: OpenAI, voice agents, automation with n8n and Temporal Cloud and DevOps: AWS, Azure, Docker, GitHub Actions, Azure DevOps, CI/CD pipelines Legacy modernization: .NET Framework to .NET 8 migrations, desktop to web Core stack: Backend: C#, ASP.NET Core, .NET 8/9, Python, FastAPI, Node.js Frontend: Angular, React, Next.js, TypeScript, Blazor, NgRx Data: PostgreSQL, SQL Server, Redis, Cosmos DB, EF Core, Dapper Cloud: AWS, Azure, Docker, CI/CD Integrations: Stripe, Twilio, SendGrid, WhatsApp, Shopify, OpenAI How I work: I learn a codebase deeply, communicate clearly about risk and tradeoffs, and give honest timelines with no surprises mid-project. I do my best work on long engagements where reliability matters and you want someone you can hand a hard problem to and trust it gets shipped. Tell me what you are trying to ship and your current stack. I will tell you straight whether I am the right fit and how I would start. Happy to do a quick call through Upwork.
