§ 01

Engineering

12+ years of backend, agentic AI, devtools and business software.

  • Natural language → formal logic

    Órganon

    The technical jewel, live: write in Spanish → autologic (rule-based NLP formalizer) translates it → ST executes it (a logic language with a home-grown CDCL SAT solver, 6,333 tests). No AI, no database: it all runs in-process, serverless on Vercel.

  • OSS dev tools

    Téchne

    Docs and showcase of OSS devtools for Linux: Ultimate Terminal (browser-based distributed machine control), Mission Center Web (Electron-free resource monitor), clawbar (voice + Hyprland status bar with Whisper/Kokoro) and Hyprland Multi-Monitor (independent per-monitor workspaces). Astro Starlight, fully static.

  • Community platform

    Koinonía

    Multi-tenant platform for Discord communities: web portal (events, library, ranking, store and roles), a NestJS 10 API over Neon Postgres and a discord.js bot with XP and voice rewards. A single codebase and database for many communities isolated by tenantId.

  • Custom SMB software

    Érgon

    Commercial landing for a suite of three ready-to-customize SMB starter kits: CRM (React + Vite + Express), Hours Tracker (Next.js 15 + Turso) and VPN Manager (Flask + Docker). Model: "80% is already built, you pay for the 20% custom". Fixed-scope sale or micro-SaaS.

  • Time tracking + invoices

    Chrónos

    SaaS app for freelance time tracking and Colombia-localized invoices: single or bulk entry, income calculation with configurable rate, PDF export, weekday filters and average-based autofill. Next.js 15 + SQLite.

  • SMB CRM

    Xenía

    CRM for Colombian SMBs with 19 entities: kanban pipeline, contacts, companies, deals, activities, quotes and invoices. Localized for tax ID, COP, departments and company types. React 19 + Vite + Express + Neon Postgres, deployed on Vercel.

  • Legal scraping

    Nómos

    Legislative document indexer with full-text search: adapts scraping to Colombia’s House and Senate and the DR Chamber of Deputies via a swappable Source Adapter pattern that never touches the pipeline. FastAPI + Neon Postgres + Mangum on Vercel serverless.

  • Inventory

    Apothḗke

    Warehouse and inventory management system: stock, orders, movements, roles (admin/manager/worker), notifications and analytics. React 19 + Vite + Neon Postgres on Vercel serverless functions, with seed demo data to start instantly.

  • Scientific editorial CMS

    Áporía

    Full-stack editorial platform (Next.js 16 + Neon/Postgres + Firebase Auth): publishes papers, archives research and runs collective experiments with real-time visualization, with a /studio panel for editorial CRUD behind real auth. The name evokes paradox, but the product is scientific publishing infrastructure.

  • Orchestrating director of the agent fleet

    Cauce V3

    My flagship engineering project: the orchestrating director of the agent fleet that operates Cauce V3 (this very portfolio and the entire Humanizar ecosystem). Deployments, monitoring, delivery contracts between agents, and a multi-tenant CRM in production. The right hand that keeps the fleet alive.

  • Brand image generator

    Eikón

    Deterministic brand-identity generator: procedural isotypes, palettes, icon sets and social kits, with WCAG contrast validation. Multi-tenant webapp + API + MCP server, in production. The engine that builds the brands of this very portfolio.

  • Independent student governance

    Koinonía UdeA

    Open-source collective governance platform for students of the UdeA Institute of Philosophy. It organizes issues, deliberations, verifiable decisions and initiatives with follow-through. This is an independent project and does not officially represent the university.

  • Debate moderator

    Agón

    Offline PWA to moderate academic and competitive debates: manages turns, timer, scoring and fallacy detection, and bundles a dynamics simulator with a cellular automaton (2D canvas) inherited from the complex-systems research.

  • Interactive atlas of experiments

    Umbral

    Interactive atlas of 23 experiments in mathematics, physics, automata and complex systems. It pairs exploratory 3D scenes with 230 documented results and source links; the scenes do not recompute the original results.

    Scientific explorationVisit Umbral ↗

  • Learn complexity by coding

    Phúsis

    Complexity science course platform with three active courses and 22 lessons. Learners code cellular automata, chaotic systems and agent-based models, with live previews, automated checks and philosophical reflection.

  • Doctoral thesis · Philosophy of science

    Estructuras Preontológicas

    Doctoral thesis (Jacob Agudelo + Steven Vallejo, UdeA) in philosophy of science and complexity sciences: proposes "pre-ontological structures" as operative regularities prior to objecthood, anchored in a dynamic material substrate and validated with the EDI metric and multiscale compression over multi-domain evidence. Quantitative rigor and ontological grounding in a single program.
