Arinze Chinweuba / Software engineering
Practical software.
Clear evidence.
Reliable systems.
I build tools and services that make complex workflows easier to inspect, automate, and trust. My current focus is networking, Linux, and practical security.
Selected work
Projects built around real constraints.
A small selection of work, with the decisions and trade-offs left visible.
Node.js
Dupload
A Telegram video downloader and media-processing bot built with Node.js, Telegraf, yt-dlp, and FFmpeg, with queued jobs, cancellation, media validation, compression, and resilient Telegram delivery.
Incident Response
DupTrace
An evidence-first incident investigation assistant that helps engineers trace service health, incidents, deployments, and events without confusing correlation with proven causation.
Rust
Mint Pilot
A Rust CLI for scheduling OpenSea mint transactions with wallet orchestration, calldata validation, transaction replacement, and experimental EIP-7702 sponsored execution.
Technical focus
Useful systems over impressive-looking demos.
The areas I use to evaluate a build: is it clear, useful, testable, and maintainable?
Engineering notes
Writing from the work.
Building Mint-Pilot: A Rust CLI for OpenSea Mint Workflows
A source-grounded overview of Mint-Pilot's collection discovery, calldata inspection, scheduled mint workflows, wallet manifests, and experimental sponsored execution.
Building Dupload: A Telegram Media Pipeline
A source-grounded walkthrough of Dupload's queueing, yt-dlp downloads, FFmpeg processing, progress updates, cancellation, and Telegram Bot API delivery.
Research
Questions worth testing.
Designing Evidence-First Incident Investigations
Design notes from building DupTrace: how to separate observations from hypotheses, preserve timelines, and make incident investigations auditable.
Working now
Building evidence-first investigation tools, improving production automation, and studying networking and security fundamentals through hands-on work.
