    C# VB.NET ASP.NET

    Modern systems need to be fast, reliable, and well-connected. Over the years I’ve seen how fragmented applications, legacy code, and manual processes slow organizations down — so I build .NET solutions that solve that.
    I specialize in C# and VB.NET development, legacy modernization, API integration, and SQL optimization, creating applications that are scalable, maintainable, and built for long-term growth.

    On this page I share the core capabilities I bring into .NET projects and how I design solutions that reduce complexity, accelerate delivery, and improve operational performance.

    I’m available to demo the below applications in a live manner (except 5-6 since they are in production at client).

    .NET Development

    Hands-on engineering using .NET Framework for enterprise applications: modern, stable, and maintainable codebases.

    Full SDLC Ownership

    From architecture and development to testing, scalability, deployment, and long-term operational support.

    Legacy Modernization

    Refactoring and upgrading older systems with improved structure, componentization, and long-term scalability.

    Test Automation & Quality Frameworks

    Reflection-based execution engines enabling repeatable, automated validation across complex systems.

    Workflow & Process Automation

    Transforming repetitive operations into streamlined flows across financial, CRM, sales and operations teams.

    Office Interop & Document Generation

    PowerPoint, Excel, Word and Outlook automation — proposals, reporting, financial imports, and email flows. See also

    API & System Integration

    Linking CRM, ERP, billing, document systems and external services into a reliable automation layer.

    SQL Server Performance & Optimization

    Query tuning, indexing, restructuring data flows and improving backend speed + maintainability.

    Cases: Implementation samples

    Example 1: Bookkeeping and Financial Process Automation

    Digitally modernized a fragmented financial workflow by automating CSV imports, Excel reconciliation, invoice renaming, and file routing across OneDrive and ERP systems. Centralized data handling, reduced bookkeeping workload by over 70%, and delivered a maintainable .NET Framework solution with consistent document and transaction processing.

    Example 2: Test Automation Framework

    Introduced a scalable, data-driven test automation framework built on .NET Framework, enabling Reflection-based execution of any C# or VB.NET method. Standardized functional and integration testing, automated result logging, and reduced validation time by more than 80%. Established a reusable engine for continuous, reliable, and auditable system testing. See more details by clicking here

    Example 3: Sales Contact and CRM Automation

    Unified contact handling across LinkedIn, Outlook, Excel, and Dynamics 365. Automated profile extraction, deduplication, CRM synchronization, and metadata cleanup. Improved sales readiness, strengthened data quality, and eliminated repetitive manual updates through a centralized .NET-based automation tool. See more details by clicking here

    Example 4: End-to-End Automation of Sales Demo and Proposal Process

    Developed a fully automated proposal engine integrating PowerPoint, Excel ROI models, Word SOW templates, and Outlook email generation. Transformed a 4 hour manual workflow into a 30 minute, template-driven process that ensures consistent branding, accurate data population, and faster customer response cycles.

    Example 5: End-to-End CRM, Quoting & Billing Integration

    Connected Dynamics 365 Sales with Bit2Win, DocuSign, Stripe, and Trello through a unified .NET integration layer. Automated quoting, contract signatures, billing setup, SOW creation, and resource handoff to field consultants. Removed duplicate data entry, improved process accuracy, and delivered seamless end-to-end sales-to-delivery orchestration. See more details by clicking here

    Example 6: Backend Modernization & API Integration Framework

    Modernized a legacy VB.NET/ .NET Framework backend by introducing standardized API integration layers, SQL Server optimization, reusable shared components, and structured logging. Reduced technical debt, improved maintainability, and created a scalable architecture for future service integrations and platform evolution. See more details by clicking here
