Open-source developer from Mossoró, Rio Grande do Norte - Brazil. I build driftcheck — a CLI that catches version drift between docs and toolchain files before your contributors hit a build failure. I also contribute to agent runtimes and AI infrastructure: provider error classification, retry UX, tool schemas, test-suite migrations and the CI hygiene that keeps big repos mergeable. Steady, reproducible, reviewed — one focused PR at a time.

• Open PRs: open pull requests across agent runtimes, open-data tooling, and upstream reproducibility — including Rust/Go version sync, NER test config, and stdlib test-suite migrations. Currently in flight:
  • fmtlib/fmt#4918 — sanitize non-UTF-8 bytes from std::error_code::message() (fixes #4436)
  • debpalash/VoiceStudio#1801 — guard null seg.start/end in .toFixed() (fixes #1798)
  • THU-MAIC/OpenMAIC#1343 — CI: bump upload-artifact + cache to Node 24 versions (awaiting re-review)
  • medusajs/medusa#16715 — translate country/currency names using Intl.DisplayNames (awaiting review)
  • rancher/dashboard#19043 — support IPv6 CIDR in isValidCIDR validator (awaiting review)

• 🔍 yunaremaia/driftcheck — my own project. Detects version drift between docs and toolchain files (README vs Dockerfile, build.gradle, pom.xml, versions.tf, .circleci/config.yml, .gitlab-ci.yml, GitHub Actions versions, and more). 80+ tests, 15 drift types.
• 🏛️ apache/maka (ASF agent runtime) - five merged PRs in one week: permission-mode refactor, usage-limit billing paths, humanized retry delays, DeepSeek V4 Flash metadata, and a desktop flake fix.
• ⚡ modular/modular - stdlib test-suite modernization in Mojo: test_string_span_bounds_abort migration.
• 🔐 decionis/agent-safe-pipeline - cryptographic-agility docs, TLS verification posture, and Unicode edge-case conformance vectors (#56, #55, #23).
• 📊 semantica-agi/semantica - vector-store persistence fixes, reproducible CI dependency pinning, and a private-IP opt-in for trusted internal APIs (#914, #945, #959).

• 🔍 Drift detection — version drift between docs and toolchain files (Dockerfile, build.gradle, pom.xml, versions.tf, CircleCI, GitLab CI, GitHub Actions, and more)
• 🤖 Agent runtimes & LLM tooling - provider billing/error taxonomies, retry UX, MCP tool schemas, capability systems (TypeScript, Python, Rust)
• 🔬 Test infrastructure & CI hygiene - flake elimination, conformance vectors, reproducible pipelines (Rust, Python, Mojo, C++)
• 🔤 Encoding & Unicode correctness - UTF-8 sanitization, Windows code-page edge cases, std::error_code formatter robustness (C++)
• 📊 Open data - schema-validated vendor/startup program datasets
