Tu CV Cuenta — AI CV Reviewer

Problem

Job seekers get rejected by automated filters before a human reads them, and never learn why. Free tools give generic advice; this product tells people what the machine saw, with an honest, audited score.

Role

Solo product owner and developer: product decisions, architecture, AI pipeline with anti-hallucination layers, UI, accessibility, testing and serverless deployment.

Key decisions

• Multimodal AI reads the actual PDF document, and every score passes an adversarial auditor before reaching the user.
• Contact data is anonymized in the browser before any processing; nothing is stored server-side.
• The .docx editor corrects the original XML so the user's own design survives intact.

Result

A free public product in production at ats.sintitulo.dev, accepting CV uploads in PDF and Word, with the audit trail of every AI claim visible to the user.

Limitations

The source repository is private, so the running product is the verifiable evidence. Scores are advisory and do not predict hiring outcomes.

Agent Systems & Portable Memory

Problem

Make a planner-builder workflow inspectable without presenting synthetic telemetry as production evidence.

Role

Designed and implemented the bilingual case study, deterministic replay, authority boundaries, and verification contract.

Key decisions

• Kept the replay deterministic and local.
• Separated educational simulation from public evidence.
• Documented human approval gates and failure modes.

Result

A bilingual technical case study with a deterministic replay covered by unit and browser tests.

Limitations

The replay is educational and does not execute external models, production workloads, or sensitive data.

Voces y Agentes – Youth Advocacy Lab

Problem

Create a clear public web presence for a youth advocacy laboratory and its participation model.

Role

Implemented and published the React and TypeScript front end represented by the linked public source repository.

Key decisions

• Used a static front end suitable for GitHub Pages.
• Structured program information for a public, mobile-friendly experience.
• Kept source code and the deployed site publicly inspectable.

Result

A deployed public site on the GOYN México domain with its front-end source available for inspection.

Limitations

This portfolio does not claim ownership of GOYN program outcomes, participant data, or funding results.

Personal Portfolio — santiagOS

Problem

Present bilingual professional evidence inside a retro operating-system interface without sacrificing static HTML, accessibility, or security.

Role

Designed, built, and maintains the Astro and Svelte portfolio, its content model, interaction shell, and verification suite.

Key decisions

• Moved public content to static Astro Content Collections.
• Centralized bilingual routes, canonical URLs, and navigation.
• Reserved Svelte for interaction and kept public claims evidence-aware.

Result

A static bilingual portfolio with centralized routing, keyboard workflows, security boundaries, and automated regression coverage.

Limitations

Professional metrics and private work remain self-reported unless a public source is linked; physical-device QA is tracked separately.
