Robust, secure, and scalable backend and web application development using Microsoft’s powerful .NET ecosystem.
🏢 Trusted by Enterprises for a Reason
When performance, compliance, and long-term scalability are non-negotiable, C# and ASP.NET remain the technologies of choice for governments, banks, healthcare providers, and global enterprises. At TAS, we specialize in C# / ASP.NET development to build enterprise-grade applications, admin dashboards, reporting systems, secure APIs, and cloud-native platforms that can withstand mission-critical use cases and massive user loads.
We understand the unique challenges of enterprise environments—multi-layered architecture, strict security protocols, legacy integrations, and large-scale data processing. That’s why we bring in-depth expertise in the .NET ecosystem, including .NET Core, ASP.NET MVC, Web API, Entity Framework, SignalR, and Azure cloud deployments to deliver stable, future-ready backend systems and business applications.
💼 Why Enterprises Choose ASP.NET & C#
C# and ASP.NET provide a high-performance, statically typed, object-oriented framework that is perfect for building secure, modular, and maintainable backend systems. With a mature ecosystem, vast library support, and first-class tools from Microsoft, it’s the ideal choice for large organizations and high-compliance industries like finance, insurance, healthtech, and logistics.
Using ASP.NET Core, our team builds APIs that are cloud-agnostic, container-ready, and compatible with modern frontend stacks like React, Angular, or Blazor. Whether you need a greenfield backend system or to modernize an existing legacy .NET stack, TAS has you covered.

📈 Real Project Highlights
📚 Shabd.in – Multilingual Publishing & Book Management Platform
We developed the backend system for Shabd.in, a high-traffic platform enabling authors to publish books in over 10 Indian languages. Using ASP.NET Core and SQL Server, we engineered scalable APIs for user management, payment processing, publishing workflows, content moderation, and digital rights management. The platform supports role-based author/editor accounts, royalty tracking, and real-time analytics
📢 Sociota.net – Social Media Monitoring & Automation Tool
Sociota.net required a robust backend to support social media scheduling, multi-account management, and sentiment tracking. We built a modular ASP.NET backend integrated with Twitter, Facebook, and LinkedIn APIs, handling millions of API calls monthly. The backend also powered a custom analytics dashboard, cron-based post scheduler, and OAuth-driven account control for thousands of users.
🛠️ Legacy .NET Migration for Industrial ERP Client (NDA Project)
Re-engineered a legacy .NET 4.5 system handling inventory, finance, and vendor workflows into a modern .NET Core 6 application. This reduced server load by 40%, enabled API access for mobile clients, and introduced modular CI/CD with Azure DevOps.
