Technical Writing Portfolio

About Me

I write cloud deployment and self-hosting guides for developer tools, with published work on Vultr and freeCodeCamp. My work focuses on Docker-based setups, Linux servers, and open-source infrastructure.

I test every guide on a live VPS to ensure it works exactly as written and covers real deployment issues developers face. I also co-author peer-reviewed AI research published on IEEE Xplore and ScienceDirect.

My goal is to make complex deployments easy to follow so developers can get systems running without unnecessary trial and error. I work in a Docs-as-Code workflow using Git, Markdown, and pull requests—the same process used by modern engineering teams.

Selected Work

Vultr Docs

How to Deploy Kestra — Open-Source Workflow Orchestration Platform

A step-by-step cloud deployment guide that helps developers self-host Kestra on a VPS without setup or configuration issues. I worked independently to research, write, and test the guide end-to-end on a live server, focusing on Docker-based deployment and a stable environment setup. The article went through multiple review cycles with the DevRel team and was published on Vultr Docs.

freeCodeCamp

How to Self-Host AFFiNE on Windows with WSL and Docker

A step-by-step self-hosting guide that helps developers run AFFiNE locally using WSL and Docker without setup or environment issues. I wrote and tested the guide end-to-end, focusing on clear instructions for Docker setup and WSL configuration. The article went through editorial review by the freeCodeCamp team and was published on freeCodeCamp.

How to Troubleshoot Ghost CMS: Fixing WSL, Docker, and ActivityPub Errors

A troubleshooting guide that helps developers fix common errors while running Ghost CMS with WSL and Docker, including issues related to ActivityPub and environment setup. I wrote and tested the solutions end to end, focusing on identifying root causes and providing clear fixes for each problem. The article went through editorial review by the freeCodeCamp team and was published on freeCodeCamp.

How to Self-Host Your Own Server Monitoring Dashboard Using Uptime Kuma and Docker

A step-by-step self-hosting guide that helps developers set up a server monitoring dashboard using Uptime Kuma and Docker without configuration issues. I wrote and tested the guide end to end, focusing on Docker setup, service configuration, and ensuring a stable monitoring environment. The article went through editorial review by the freeCodeCamp team and will be published on freeCodeCamp.

How to Build a Résumé Screening System Using Python and Multiprocessing

A technical guide that helps developers build an automated résumé screening system using Python and multiprocessing to improve performance. I designed, implemented, and documented the system end-to-end, focusing on parallel processing and efficient data handling. The article went through editorial review by the freeCodeCamp team and was published on freeCodeCamp.

Docs-as-Code Workflow

I follow a Docs-as-Code workflow similar to modern engineering teams:

• Set up and test every environment on a live server before writing. If a step fails, it is fixed before documentation begins.
• Write documentation in Markdown on a dedicated Git branch using a structured template.
• Document the reasoning behind each step, not just the commands, so readers understand the system.
• Include verification steps to confirm successful setup at each stage.
• Submit documentation via pull requests and refine it through structured review cycles before merging.

This repository is maintained using the same Docs-as-Code workflow, where each update is created on a separate branch, reviewed via pull request, and deployed through a CI/CD pipeline using GitHub Actions.

How I Can Help

I help teams create clear, production-ready documentation for deploying and managing developer tools.

I can help with:

• Cloud deployment guides — Step-by-step documentation for deploying applications on VPS using Docker, Linux, and modern infrastructure setups.
• Self-hosting documentation — Guides for running open-source tools in real-world environments with reliable configurations.
• Troubleshooting and debugging guides — Clear breakdowns of common errors with root causes and practical fixes.
