Hi, I'm Sachin Tanwar: .NET solution architect and full stack developer

I started my career in 2012 as a software engineer at an Indian software company, where I worked on more than 50 web and mobile projects using Microsoft technologies. That variety taught me how differently businesses use software, and how much good architecture matters once a product starts to grow.

In 2015 I joined a France-based multinational as a senior consultant, working on systems for investment banks and global payments, domains where performance, security and correctness aren't optional. Since 2018 I've worked full time as a freelance .NET developer and architect, building products for clients in the USA, UK, Europe, Australia and India, and earning Top Rated Plus status on Upwork with a 100% Job Success Score.

My core stack is C#, ASP.NET Core, Entity Framework Core and SQL Server or PostgreSQL, hosted on Azure or AWS with Docker and CI/CD. On the front end I use Blazor, React, Angular and modern JavaScript. I also help teams modernise legacy .NET Framework applications and add AI features with Azure OpenAI and Semantic Kernel.

I've built aviation cost analytics, warranty management, e-commerce, recruitment, workforce management, online assessments and legal filing platforms. You can see examples on the projects page, or read my articles on .NET architecture and development.
