About me

Freelance developer and systems engineer since 2023, with seven years of overall hands-on technology experience. My work covers Python and web development, data processing, systems architecture, automation, cloud infrastructure and hardware-focused projects.

I build data-cleaning and conversion tools, CSV/JSON validation, Python utilities, API integrations, SQL queries and exports, and responsive HTML/CSS layouts. I also work with Rust, JavaScript, AWS, Cloudflare, systems administration and self-hosted services.

I evaluate AI models, coding workflows and infrastructure for cost, speed and capability, focusing on maintainable systems and reusable automation. My public portfolio contains labelled personal projects and synthetic demonstrations. For each assignment, I agree the full scope, required inputs, acceptance checks and delivery schedule, then provide clear outputs and handover instructions.
