Experience

Founder & Lead Engineer

2020 — Present

Mounaji Studio · Córdoba, Argentina — Remote

Architect and main author of the studio’s AI products: CognitionDesk, the coding-agent platform, the Cockpit, Cortex, AgentLaw and Magnicia (details under Projects).
Run production on a self-managed VPS: Docker Compose behind Caddy, the API on two replicas with connection draining on every deploy, and one-command rollback to a previous commit.
Published the shared code as npm packages (50+ under @mounaji_npm; AgentLaw under @agentlaw, Apache-2.0), so a fix lands once and reaches every app.
Shipped the studio’s own products, each with a public site — CognitionDesk, Kondor, Turnia, LogScope, Fixi Hogar and AgentLaw — and two games on Google Play. Built and led a team, and created paid work for other developers.

Full-Stack Developer — Client Work

2020 — Present

Independent · Remote

Client work in sportswear e-commerce (since 2023) and school nutrition: I build the product and keep it alive after launch.
Delivered a platform for a team of nutritionists working across schools, with an agent that reads their spreadsheets so nobody has to retype them.

Cockpit Desktop app · internal

Cortex Curated context for agents

2026

A service that hands every agent, in one MCP call, a brief with the project’s rules, decisions and learnings plus a map of the code.
