My profile https://www.linkedin.com/in/riya-bhandekar-5ba01956/
Being a software developer is more than just learning to program in a computer language. I have been building .NET web apps for years and multiplayer games since 2015, using Unity 3D using Photon Fusion (server-authoritative). I have also designed and/or worked on enterprise web sites from concept to deployment, some high-profile projects. I have served as a Senior or Lead Developer for years, mentoring other developers and encouraging them to use the latest technologies and best practices. For tutoring, I would focus on teaching design patterns, using events and encapsulation when designing applications and reinforcing the need to keep your skillset current as new technologies are released. I can give advice on how to focus your learning efforts to target specific types of development positions, and interviewing advice for finding a position within a software company. I had been a developer in C++ for about 10 years prior to using C# and focused on web technologies prior to working with Unity 3D.
While I have primarily been using Unity 3D and Microsoft .NET / C# recently, I have also utilized legacy technologies like Classic ASP, VB and VB.NET, COM/DCOM, worked with Linux/PHP/MySQL from time to time, and worked with the Microsoft SQL Server/Express/CE products for 10+ years. I also have formal SCRUM training, which is used by many companies for handling team project management.
For Unity 3D multiplayer networking projects I typically work with and recommend Photon Fusion along with PlayFab integrations, PlayFab Matchmaking, and PlayFab GameServers.
If your college project is a "Concept to POC" type of project where the Proof of Concept is the working software required for a grade, then I will also teach you to use a Git repository to manage the project (or Plastic/UVCS for Unity projects).
I can help you document the Project Scope, Functional Specs, create Design Documents, and build the presentation for your college project. We can build completed projects in a short time, both the user interface and the server components as needed.
My focuses are Unity 3D multiplayer, C#, .NET Core
Since 2009, I’ve actively immersed myself in the IT, programming, startup, and blockchain realms. My journey has been rich with diverse experiences, from entrepreneurship and startup involvement to collaborating with large corporations. Over the years, I’ve worn various hats—CTO, Developer, DevOps, and Scrum Master—working across a spectrum of languages and frameworks: Solidity, Hardhat, PHP, Laravel, JavaScript, Node.js, Vue, MySQL, MongoDB, Elasticsearch, and more. My passion lies in decentralization and blockchain technology. I firmly believe that programming transcends specific languages or expertise; adaptability is my forte.
I'm an analytical but creative software engineer with a love for applying tech against interesting domains and problems. I have a knack for taking tough concepts and presenting them in a way that's easy to understand - if analogies are your thing I think you'll find that I have the perfect one for any situation. My work is backed with results, I have been tutoring a friend of mine for a year or two, and he was able to use the knowledge I taught him to transition from Application Specialist (non-coding role) to a Software Engineer at his company!
Please see my personal portfolio site and Github for video game mod related projects, and other assorted coding endeavors!
