Quality Engineering
QA strategy, automation, and AI-assisted testing
Operating model transformation, risk-based automation design, and intelligent CI/CD tooling.
Quality Assistance Model
Lead Software QA Engineer · Engineering-wide transformation · Trellis
Replaced a siloed QA gatekeeping model with a Quality Assistance approach that shifted ownership into the engineering team, rebalanced automation around risk, and made release confidence part of the delivery system, not a late-stage approval ritual. The change touched how teams planned, how PRs were reviewed, how incidents were analysed, and what "done" actually meant.
Android PR Acceptance Testing Agent
Claude-powered GitHub Actions agent that selects which of 60 instrumented Android tests to run per PR using diff analysis, runs them on a managed emulator across up to 4 shards, then diagnoses failures and posts coverage gap recommendations directly to the PR comment.
LLM PR Regression Checker
Autonomous pull request review agent that compares code diffs against a vector-backed library of historical bugs, then posts evidence-based regression feedback directly into GitHub review flows.
