}- 🏆 #1 contributor to Twake Mail (3.6k+ commits), an open-source, multi-platform email client on the JMAP protocol.
- 📦 Maintaining Dart & Flutter packages on pub.dev (see below), from UI widgets to a DNS/IP networking stack.
- 🤖 Learning, researching and building AI tools that automate the software lifecycle, from spec to review, QA and release, to cut delivery time without lowering the quality bar (more).
- 🌱 Currently researching multi-agent orchestration, MCP integrations and LLM evaluation & guardrails.

Mission: automate every repeatable step of software delivery with AI agents, so engineers spend their time on design and judgment, not on toil.
Principle: AI proposes, deterministic checks decide. Every agent output is verified by tests, policies or a human before it ships.

| Tool | What it automates |
|---|---|
| 🧪 qa-agent-kit | Evidence-driven QA for pull requests: permission test matrices, a checksummed evidence registry and a GO / NO_GO release gate. AI drafts tests and triages failures; only validated results can pass the gate. |
| 🔍 Branch review agent | A Claude Code skill that reviews any MR/PR (GitHub, GitLab, Bitbucket) for architecture, correctness, performance, ReDoS, security and memory leaks, then posts line-anchored comments, fixes the branch or fills missing unit & e2e tests. |
| 📏 Agent guardrails | Shared engineering rules for coding agents: ReDoS checks measured on every regex engine, a content review before every push, consistent commits and review comments. |
| 🔄 Self-updating profile | This README: a GitHub Action ranks my projects and contributions from the GitHub and pub.dev APIs every day. |
| ✅ AI quality gates in CI | CodeRabbit and CodeScene on every PR, so humans review intent while machines catch smells and regressions. |
- 🕸️ Agentic workflows & multi-agent orchestration: splitting delivery into planner, coder, reviewer and tester agents.
- 🔌 Model Context Protocol (MCP): connecting agents to issue trackers, repos, design files and CI.
- 📐 Spec-driven development: turning specs into tasks, code and tests an agent can verify.
- 🧮 LLM evaluation & guardrails: measuring agent output with deterministic checks instead of trust.
- 🧠 Context engineering: skills, memory and project rules that make agents reliable on large codebases.
