Full-stack C# & .NET development

Custom software that connects your business.

Linkvision designs and builds robust, full-stack C# web applications, APIs and internal tools — backed by deep SQL Server & database expertise and hands-on network and infrastructure knowledge — tailored to how your business actually works, not the other way around.

What I build

End-to-end software development, focused on the Microsoft & .NET ecosystem.

Web Applications

Custom ASP.NET Core web apps — from internal business tools to customer-facing platforms — built to scale and easy to maintain.

APIs & Integrations

Well-documented REST APIs and integrations that connect your systems, third-party services and data sources reliably.

Databases & Data

Deep expertise in SQL Server and relational databases — schema design, performance tuning, migrations and reporting that keep your data reliable and fast.

Custom Software

Desktop and back-office tools in C#/.NET tailored to your workflows — automating manual work and reducing errors.

Architecture & Infrastructure

Technical guidance on system design, network and infrastructure choices, code reviews and modernizing legacy .NET applications.

Maintenance & Support

Ongoing support, bug fixes and feature development for existing C# applications — so your software keeps up with your business.

Consulting

Not sure where to start? I help translate business needs into a practical, buildable technical plan.

Recent work

A few examples of projects I've built. Case studies coming soon.

ANPR Security Platform

InvestiPlate

A real-time ANPR platform for Spyke Security that matches scanned license plates against watchlists and national vehicle registries, instantly alerting security operators across multiple camera sites.

IT Operations Monitoring

SmartOps

An IT operations monitoring platform for Spaansen, tracking the health of servers, websites, APIs and databases through configurable checks and threshold-based alerts — all visualized on a live dashboard.

Plant Maintenance Platform

Kowalski

A plant maintenance platform for Cono that manages equipment, work orders, spare parts, safety reporting and change requests across multiple production sites from a single system.

About Linkvision

Linkvision is the practice of Dennis, a full-stack software developer specialized in C# and the .NET ecosystem — from front-end interfaces to back-end services. I build web applications, APIs and internal tools for businesses that need software that fits their exact process — not a generic off-the-shelf product.

Beyond the code, I bring hands-on experience with networks and infrastructure and a deep, practical knowledge of SQL Server and databases — so the systems I build are not just functional, but well-architected, secure and performant from the database up to the network.

Whether you need a new application built from scratch, an existing system modernized, or a second opinion on your architecture, I work closely with you from first conversation to deployment and beyond.
