I build small, sharp tools that do one job and finish: CLI utilities, data cleaning and migration scripts, report automation, and rework of legacy systems. Everything I claim is checkable. In six days in August 2026 I shipped nine public repos, with source, unit tests, real-artifact verification and signed releases, all open at github.com/xiaoqiMikko. Examples: log4j-check runs 93 unit tests and is verified against 12 real-world jar scenarios; shiro-check expands 26 advisories into 37 rules across 7 modules; pac4j-check is backtested against all 147 published versions and matches the official ranges exactly, and that check runs in CI. How I work: you send one sample file or a reproducible example, and I write back what "done" will look like before writing any code. Fixed price, fixed date, never hourly. I run the tool against your real data before handover, and I reply within one business day. Payment in stablecoins through LaborX escrow; USDC works on all six chains it supports.
