I ship features, fixes and tooling into real projects, with tests, and I say exactly what was checked.
17 merged pull requests in 8 repositories in the last week, including maintainers' own review and CI:
| Mozilla neqo · 2.2k★ | Firefox's QUIC / HTTP/3 stack, Rust |
| OpenRig · 8k★ | multi-agent CLI, TypeScript |
| Tabularis · 5k★ | desktop SQL client (Tauri, Rust, React): 8 merged features |
| Hiero JS SDK · Linux Foundation Decentralized Trust | JS/TS SDK, 2 merged PRs |
A PR from me follows the project's own conventions, comes with tests, passes the full CI, and the description states what was run and what was not.
I take fixed-scope jobs where the result is something you can run and review:
| What | Examples |
|---|---|
| Bots and automation | Telegram bots, alerting, parsers, scheduled data jobs |
| Crypto data & dashboards | Exchange/on-chain data pipelines, signal and risk dashboards, AI-assisted analysis |
| Features and bug fixes | In Rust, TypeScript / React, Python, Node.js: scoped, tested, documented |
| Smart-contract tooling | Soroban (Stellar) and Anchor (Solana): tests, SDK helpers, review of edge cases |
How it works: you describe the task, I confirm scope and price up front, deliver in small reviewable steps, and explain every change. No surprises.
