R&D playground by Daniel Fuentes - experiments, prototypes, and tech spikes.
VJ = Vicente & Joaquín (my twin sons) — this lab is named after them.

This space is for learning in public: trying ideas fast, documenting what works, and sharing useful building blocks.
Production-grade delivery happens at Atelier Busco. VJ Lab is the experimental wing.

• Daniel (Personal) — notes, ideas, and foundational research.
• Atelier Busco (Studio) — client-facing products, production quality, SLAs.
• VJ Software Lab (Lab) — experiments, prototypes, OSS utilities, and technical proof-of-concepts.

• Prototypes & MVP spikes (mobile/web/backends)
• Architecture trials (serverless patterns, modular frontends, event-driven systems)
• AI/LLM experiments (RAG, eval harnesses, prompt engineering, agents)
• Dev tooling (CLIs, validators, code generators, CI/CD recipes)
• Data & dashboards (ETL stubs, observability demos, cost monitors)
• Teaching assets (sample apps, playgrounds, workshop material)

If something proves valuable, it may graduate and move to a dedicated repo or into Atelier Busco projects.

• 🧪 Lab — unstable, breaking changes expected, minimal docs.
• 🔬 Incubating — gaining traction, clearer API, basic docs & tests.
• ✅ Graduated — stable and moved/linked from here (see the repo’s README).

Use at your own risk. Not production software unless explicitly marked Graduated.

• Explore by folder or tags; each project has its own README.
• Look for ADR.md / NOTES.md for context and decisions.
• Issues and discussions are welcome if the repo is public.
• Reuse freely where licenses allow (see each project’s LICENSE).

Default license is MIT, unless a project specifies otherwise.

• A portfolio site or sales page (that’s Atelier Busco).
• A place for client artifacts, private data, or NDAs.
• A promise of long-term maintenance for experimental code.

• PRs and issues are welcome on public repos.
