I build the custom software that off-the-shelf tools can't. Because I've also run finance and operations as a director, I build it to actually fit how your business works. I'm a full-stack developer and the founder of Alpen Ventures, where I architect bespoke, enterprise-grade B2B platforms and automate the manual workflows that slow growing companies down. What sets me apart: alongside engineering, I currently serve as a Director of Finance and a Director of Operations, so I speak both languages. I don't just ship features; I understand margins, cash flow, billing, reporting, and the operational reality your software has to support. What I build: • Custom SaaS & B2B web apps — Next.js, TypeScript, React, Node, PostgreSQL • Finance & ops tooling — billing/invoicing systems, dashboards, forecasting & KPI reporting, internal admin platforms • Workflow automation & AI integrations that remove manual work • Complete products, end to end — from data model and architecture to a polished, deployed UI Why clients trust me with it • As Director of Finance, I rebuilt budgeting into a predictive, data-backed model and run the billing, reporting, and KPI systems for a services firm • As Director of Operations at a scaling hardware startup, I built the operational systems, financial models, and investor materials • Managed a multi-million-dollar, multi-country budget abroad and cut ~$10K/month through better process • Grew my own service business to 200+ customers (80% returning) and a 900% increase in bookings. I understand the business owner you may be building for I work fast, communicate clearly, and treat your project like a product I own — not a ticket. You get clean, scalable, secure code from someone who actually understands the bottom-line outcome behind the build. Need a developer who gets both the code and the numbers? Tell me what you're trying to build and I'll tell you exactly how I'd approach it.

7+ years as 𝗮 𝗳𝘂𝗹𝗹 𝘀𝘁𝗮𝗰𝗸 .𝗡𝗘𝗧 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿. Over $3K earned on Upwork with Top Rated Plus status, 100% Job Success, and 1,70+ hours across 4 contracts. I build robust, scalable web applications on the Microsoft stack end to end: ASP.NET Core, C#, Angular, SQL Server, and Azure. ✅ Full stack .NET developer: ASP.NET Core backend in C# plus Angular or Blazor frontend, owned end to end ✅ ASP.NET and ASP.NET Core: MVC, Web API, .NET 6/7/8, Entity Framework, LINQ ✅ C# developer: clean, maintainable, testable C# across the full application ✅ Azure cloud and DevOps: App Service, Azure SQL, Azure DevOps, CI/CD, Docker, Kubernetes ✅ Angular and Blazor: component architecture and responsive UI on a .NET backend ✅ SharePoint: custom development, integration, and migration ✅ Microservices: modular .NET services, REST APIs, and scalable backend architecture ✅ Cross-platform: .NET MAUI and Xamarin mobile apps sharing a C# codebase ✅ Data: SQL Server, Azure SQL, PostgreSQL, T-SQL, SSIS, and Power BI reporting 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 𝗔𝗦 𝗔 𝗙𝗨𝗟𝗟 𝗦𝗧𝗔𝗖𝗞 .𝗡𝗘𝗧 𝗗𝗘𝗩𝗘𝗟𝗢𝗣𝗘𝗥 Full stack .NET web applications - As a full stack .NET developer I own the complete build: an ASP.NET Core backend in C#, an Angular or Blazor frontend, a SQL Server or Azure SQL data layer, and deployment to Azure. ASP.NET Core web development from requirements through launch, with one .NET developer accountable for the whole stack rather than a single layer. ASP.NET and ASP.NET Core development - As an ASP.NET developer I build MVC and Web API applications in C# on .NET 6/7/8, with Entity Framework and LINQ for the data layer. ASP.NET Core work covers clean architecture, dependency injection, authentication and role-based access, and the API contracts the Angular frontend consumes. The ASP.NET backend I deliver is documented and structured so your team can extend it. Azure cloud and DevOps - As a full stack .NET developer on Azure I handle App Service, Azure SQL, Azure DevOps pipelines, CI/CD, Docker, and Kubernetes. Azure work covers cloud migration of existing ASP.NET applications, infrastructure setup, environment configuration, and the monitoring that keeps a production .NET application healthy. Angular and Blazor front ends - As a full stack .NET developer I build Angular and Blazor front ends wired directly to the ASP.NET Core API. Frontend work covers component architecture, state management, responsive UI, and data-heavy dashboards that stay fast as the data grows. SharePoint development and migration - As a SharePoint specialist I deliver custom SharePoint development, integration with line-of-business systems, and SharePoint migration. SharePoint work spans intranet and document-management solutions built and maintained alongside the wider .NET stack. Microservices and API development - As a full stack .NET developer I design modular microservice architectures in C# and .NET, with REST APIs, service boundaries, shared authentication, and an Angular frontend that works cleanly against a distributed .NET backend. I split a monolith only where the boundaries are real. Cross-platform mobile with .NET MAUI and Xamarin - As a .NET developer I build cross-platform mobile applications with .NET MAUI and Xamarin, sharing a C# codebase across iOS and Android and connecting to the same ASP.NET Core API the web client uses. Enterprise and data solutions - As a full stack .NET developer I deliver data-intensive enterprise solutions: SQL Server and Azure SQL data modeling, SSIS data pipelines, Power BI reporting, and Azure Cosmos DB. The data layer is designed around how the application actually reads and writes. 𝗪𝗛𝗢 𝗜 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛 Enterprise teams and founders who need one full stack .NET developer to own an ASP.NET Core and Angular build end to end. Companies migrating existing ASP.NET applications to Azure. Teams who need an existing C# and .NET codebase maintained and extended by a developer who can read it fast. Clients who want long-running ownership, not a contractor who disappears at handoff. 𝗪𝗛𝗔𝗧 𝗬𝗢𝗨 𝗚𝗘𝗧 Every engagement starts with a review of your requirements or your existing ASP.NET and C# codebase before any code is written. You get clean, documented full stack .NET development, an application your team can maintain after handoff, and a developer who stays available after launch. Share your scope and I will come back within 24 hours with a full stack .NET development approach and estimate.
