You will get ASP.NET Developer to Stabilize & Scale Collaboration Platform
Top Rated
Project details
I stabilize and scale collaboration platforms built on ASP.NET, ASP.NET Core, and ASP.NET MVC — eliminating weekly outages, performance bottlenecks, and technical debt. ASP.NET developer back-end development covers Microsoft SQL Server optimization, database design improvements, and CI/CD pipeline setup on Microsoft Azure. API integration with third-party collaboration tools, Node.js services, TypeScript refactoring, and AngularJS front-end stabilization ensures the platform scales reliably under real production load with zero downtime.

Asp.net core crm developer
Vadym`s team did a great job on our ASP.NET Core CRM project. They got started quickly, code was clean, and communication was always smooth. Would work with them again.

ASP.NET Developer Needed - Quick Task
Vadym completed the task cleanly and efficiently. He is an excellent ASP.NET developer - identified the DateTime.
Now bug straight away - correctly flagged it as a timezone issue and replaced it with DateTime. UtcNow, which is the right fix for a distributed environment. The new /api/orders/summary endpoint was well-structured, followed our existing Clean Architecture pattern, and handled both the date range validation and the 404 case as specified.
Code was easy to read and required no follow-up questions. Delivered on time. Would work with him again!

What I build as a .NET full stack developer
My deepest work is in ASP.NET Core back-end development. I spent years as the lead .NET full stack developer on a platform managing thousands of wind and solar energy installations globally, processing massive volumes of real-time data, building microservices on .NET Core and Azure, and reducing critical downtime incidents by over 40% through improved monitoring and analytics. On another project I built a Loan Origination System in ASP.NET Core that automated the entire loan lifecycle from lead capture to loan issuance, integrating with HubSpot, external CRMs, and RESTful APIs on Microsoft Azure. The client went from manual processing to a fully automated fintech pipeline handling 550+ active applications, cutting processing time by 60%.
ASP.NET developer work across enterprise and defence
Some of my most complex work as an ASP.NET developer has been in defence and industrial sectors. I modernized a legacy web platform for a company managing 36 high-uptime naval fleet assets, warships that cannot afford downtime. The ASP.NET MVC rebuild reduced manual reporting time by 70% and enabled real-time asset tracking, secure document storage, and streamlined access to sensitive operational data. On another engagement I took over a large workplace management SaaS development project built by a single developer who had left, no documentation, weekly outages, daily hotfixes. I stabilized the ASP.NET Core back-end, eliminated the performance bottlenecks, and reduced unplanned incidents from weekly to zero within two months.
ASP.NET Zero and enterprise acceleration
ASP.NET Zero is my go-to when enterprise clients need multi-tenancy, role-based permissions, and audit logging without spending the first three sprints on boilerplate. I have used it to accelerate SaaS development on projects in pharma automation, workplace management software, and industrial IoT, cutting initial setup time by 3+ weeks and letting the team focus on actual business logic from day one. On average my clients ship their first production release 30% faster on ASP.NET Zero compared to building from scratch.
Full-stack web development across the whole system
As a .NET full stack developer I own the entire delivery, ASP.NET Core back-end, Angular or React front-end with clean web design, Microsoft SQL Server and PostgreSQL database design, and Azure infrastructure. I built a Shopify fulfillment tool in ASP.NET Core and React that reduced packing mistakes to zero and cut order processing time by 35%, integrating barcode scanning, inventory management, and connections to 8+ shipping providers. I delivered a fleet management system in .NET Core and Angular handling 1,250+ assets and 845 active rentals simultaneously, with automated reporting that saved operations teams 10+ hours per week. On the front end I work with Angular, React, TypeScript, JavaScript, Next.js, HTML, CSS, Bootstrap, and RESTful API integration, connecting them cleanly to .NET back-ends without creating maintenance nightmares six months later.
C# and .NET developer engineering that goes deep
Back-end development across 8 years as a .NET developer means I have seen what breaks under real load. I cut a US e-commerce platform's page load time from 8 seconds to 2, directly contributing to a 2x increase in sales. I optimize Microsoft SQL Server and PostgreSQL queries, regularly reducing query execution times by 60-80%, design database schemas that support complex reporting, and build API integration layers connecting .NET systems to CRMs, ERPs, payment gateways, and third-party platforms. I work with Node.js for event-driven services, TypeScript to keep large codebases maintainable, and Python or PHP when projects need scripting layers alongside the core .NET stack. For web development infrastructure I use Microsoft Azure and Amazon Web Services, Docker containers, microservices architecture, and CI/CD pipelines that reduced deployment time by 50% for several enterprise clients.
Why clients come back
I have worked with clients in Germany, the USA, Australia, the UK, Norway, Denmark, and the Netherlands across renewable energy, defence, fintech, e-commerce, and industrial IoT. What stays the same: I ask the right questions before writing the first line of code, flag problems early, and deliver .NET full stack applications that work in production, not just in development. If you are scaling a SaaS product, modernizing a legacy system, or need a .NET full stack developer your team can build on, let us talk.
