I build agentic engineering systems, security tooling, and product operations that turn ambiguous work into tested, reviewable software. My current obsession is making autonomous development accountable: narrow diffs, reproducible evidence, hard QA gates, and useful products at the end.

Based in Mexico City. Working in public across AI agents, developer tooling, OSINT, cybersecurity, and automation.

Recognizable organizations accepted this work into the software people use. The strongest, sustained contributions lead; every accepted contribution remains visible below with its exact code-review receipt.

	Maigret · eight merged investigations into better OSINT #2318 · #2442 · #2558 · #2588 · #2779 · #2929 · #2930 · #3024 — turned noisy identity searches into stronger evidence: fewer false positives, healthier site detection, modern XMind exports, and status-code checks that distinguish redirects from genuinely missing profiles. Eight accepted changes now show sustained maintainer trust, not a one-off contribution. Python · OSINT reliability · HTTP evidence · data exports · sustained maintenance
	Palantir · Blueprint #8165 MERGED — made large React migrations safer by detecting deprecated components hidden behind aliases. TypeScript · React · static analysis
	Texas Instruments · embedded developer tooling open-pru #139 MERGED · processor-sdk-doc #720 MERGED — improved portable assembly workflows and made Android SDK documentation more reliable to build and maintain. Embedded systems · assembly toolchains · Linux/Android documentation
	Sentry · Python SDK #6241 MERGED — gave teams a privacy control that drops scrubbed user IP addresses from the official SDK. Python · privacy · SDK behavior
	OWASP · Agent Security Regression Harness #149 MERGED — enabled more realistic, authenticated HTTP testing for AI-agent security regressions. Python · agent security · HTTP testing
	Aqua Security · Trivy #10828 MERGED · #10857 MERGED — made a widely used software-supply-chain scanner easier to operate correctly. Go ecosystem · security · developer experience
	Google Labs · design.md #131 MERGED — fixed primitive rendering from specification config, keeping AI-assisted design output faithful to its source data. TypeScript · generative UI · structured specifications

Full merged ledger · every remaining security, developer tools, and infrastructure receipt

	Locust #3384 MERGED — corrected report and navbar request-rate semantics.
	mitmproxy #8196 MERGED — prevented a binary-detection crash on short network payload tails.
	Sentry · Responses #791 MERGED · #807 MERGED — fixed recorded-response failures and strengthened public Python typing.
	Zeek · package manager #222 MERGED · #224 MERGED — improved the onboarding path for a core network-security ecosystem.
	jc #692 MERGED · #711 MERGED — corrected network-parser behavior and improved command-line data tooling.

Cybersecurity + AI fieldwork · accurate status, no inflated claims

• Anthropic Cybersecurity Skills (community project) — improved cloud-security skill descriptions for agent discovery in PR #25. The proposal was closed rather than merged, so it is shown as fieldwork—not an upstream acceptance.
• Security surface covered — cloud security, malware analysis, forensics, OSINT, agent security, network traffic, and software-supply-chain scanning.
• Operating principle — reproduce the failure, make the smallest defensible change, test the claim, and link the public receipt.

New OSS pull requests from 2026-08-25 (open unless marked merged):

• Google Labs design.md #173 — packaged CLI spec command can load spec.md again.
• OWASP Agent Security Regression Harness #171 — parity tests discover nested and .yml scenarios the loader already accepts.
• mitmproxy #8405 — CSS and XML/HTML prettifiers normalize CRLF so Windows checkouts format correctly.
• Aqua Trivy #11145 — parsers and the Amazon detector no longer panic on empty strings.Fields results.
• jc #722 — preserves bracketed and empty scalar values; merged.

How I ship with agents

I run a multi-agent engineering loop with explicit ownership:

1. Jeffrey orchestrates scope, implementation, and delivery.
2. Magno handles infrastructure and heavy build/test workloads.
3. Ludwig is the senior engineering and QA gate.
4. Every non-trivial claim closes with evidence: tests, CI, review state, and a precise remaining risk.

The goal is not “AI wrote code.” The goal is reliable software with a shorter path from intent to proof.
