In my extensive tenure as a software developer, I've delved deep into automation, networking, blockchains/cryptography, and the Linux ecosystem. My present endeavours involve harnessing Ansible for Proxmox LXC-container automation and leveraging Bash and Python for blockchain node deployment and the monitoring infrastructures. I have operated now a bit over 2 years my own ASN with full rack sized bare metal infrastructure at over 99.99% uptime, thanks to well designed redundancy and monitoring. In programming my advocacy leans towards Rust for guaranteed memory-safe applications.

I help clients fix bugs, improve existing features, and build small-to-medium web app functionality using ASP.NET Core, Blazor, React, Entity Framework, and API-based architecture. I can help with: • ASP.NET Core / Web API bug fixes • Blazor and React UI fixes • React components and API integration • API integration and backend logic • EF Core and SQL database issues • Authentication and validation • Business rules and admin panels • Docker deployment and production troubleshooting My experience includes real production work with payments, SSO, Redis caching, AWS S3 storage, logging, automated testing, and CI/CD deployment pipelines. I’m strongest on the .NET/backend side, including API design, validation, business logic, EF Core, code refactoring, and production bug fixing. I also work with React for UI fixes, component updates, API integration, frontend improvements, and small feature implementation. If you need someone to understand an existing codebase, find the issue, and make a clean fix without overcomplicating it, I can help.

I am software and web developer in corporate industry for almost 7yrs. I develop quite of application using c#.net with different framework like windows application, asp.net MVC, web, net core and blazor. I am fond of using c# and also knowledge in writing test case using xunit and nunit framework. For libraries I always use fluent validator, automapper, fluent migrator, and also syncfusion and devexpress. For gitrepositories I use github, gitlab, and azure devops. For Agile Development I also use azure devops. For cloud services I always use azure I created also my own blazor component github: dadotnetkid/DynaTech I also used my own component like row,column,badge and modal, I did not used my datagrid since it is still not matured so I used syncfusion for the datagrid.
