    I am a professional Golang backend engineer with over 5+ years of professional experience building backends for various projects. - I'm comfortable with any Go HTTP library, but my favorite is Chi. - If data retrieval becomes too complex, I use GraphQL for better performance and ease of use. - I love using gRPC for internal service connections. - For real-time data communication between the frontend and backend, I use zishang/socket.io or gorilla/websocket(sometimes FE dev prefer socket.io because it is easier to implement). - Typically, I use Kafka for message queuing, but for smaller use cases, I prefer Redis queue. - PostgreSQL is my top choice for a database. - I can work with Kubernetes as a developer, though not as a DevOps specialist. - The ELK stack is my preferred tool for analyzing log data. - I am also capable of setting up CI/CD pipelines using GitHub and GitLab. - Lastly i can help frontend dev to help integrate backend api.

Future developers (if any are hired after me for maintenance/updates) can go through the code and update/refactor with ease - I know how it feels as a developer to read bad code and attempt to do anything on top of it. I also share screencasts to show the setup & execution of the code or a README file. I apply only to jobs which relies on my skill set and which I consider I can finish no matter what - implying I already have a high level mental plan on approaching/solving the problem described there. The rest I mostly leave it to the regular invites. So yeah, send me an invite to your job, we can discuss and take it forward from there. Availability and communication will never be a problem as I'm always almost available for a quick chat/call. You'll know my quality when you work with me. Looking forward to many great work experiences.

    Hi, There! I am a game developer working with Unity3D game engine and have seven years of experience developing games. I work in cross-platform development IDE like Unity3D. This game engine will allow us to develop cross-platform games rather than build native games separately, which will lower the development cost. Unity3D is a powerful cross-platform 3D engine and a user-friendly development environment. Easy enough for the beginner and powerful enough for the expert. Unity should interest anybody who wants to easily create 3D games and applications for mobile, desktop, the web, and consoles.
