I'm a developer and technical writer building small, reproducible engineering projects around developer tools, Python APIs, browser automation, and data-processing workflows.

My background is in physics and software development, with practical experience in Python, AI-assisted programming workflows, and project-based technical documentation. Recently, my work has focused on turning compact engineering ideas into runnable projects with clear README files, screenshots, tests, limitations, and practical usage notes.

• Python backend APIs and FastAPI projects
• Small developer tools and browser productivity scripts
• CSV and data-processing workflows
• Docker-based local development
• Testing and reproducible project structure
• Technical writing based on working code

A minimal FastAPI service that accepts CSV uploads and returns a structured JSON data quality report.

The project demonstrates a lightweight backend workflow: file upload handling, CSV analysis with pandas, typed response models with Pydantic, structured error handling, pytest coverage, Docker packaging, screenshots, and practical documentation.

A privacy-first Tampermonkey userscript for collapsing and navigating long ChatGPT conversations locally in the browser.

The project demonstrates a small browser-side developer tool: DOM-based UI enhancement, MutationObserver support, localStorage-based UI state, privacy-first boundaries, manual testing, troubleshooting documentation, screenshots, and clear MVP scope.
