Sandro Costa — AI Product Builder

I turn messy ideas into AI products that actually work — interface, backend, agents and data, end to end.

Process

Process01 / 03

Noise

Every idea starts like this.

A real problem, a sketch, a conversation. Before picking a model or a stack, I figure out what needs to change — and for whom.

Process02 / 03

Shape

Prototypes in days, not months.

I use AI to build fast and inside the product: agents, LLMs, vision and automation go where they create value, not where they make noise.

Process03 / 03

Signal

Live, measured, evolving.

Full-stack from database to pixel, running at the edge, with observability and metrics from the very first deploy.

What I build.

  1. A

    Agents & automations

    LLM workflows that do real work: customer support, operations, analysis and integrations between systems.

    • LLMs
    • tool use
    • RAG
    • MCP
  2. B

    Web products with AI at the core

    From MVP to scale: fast interfaces, solid APIs and AI woven into the experience — not bolted on.

    • React
    • TypeScript
    • Node
    • Python
  3. C

    Generative media

    Images, video, voice and 3D generated on demand, inside the product and on brand.

    • diffusion
    • video
    • audio
    • WebGL
  4. D

    Data & forecasting

    Models that anticipate demand, detect anomalies and turn operational data into decisions.

    • forecasting
    • anomalies
    • observability

Open source

My code does the talking.

Experiments, AI plugins and WebGL games — open for you to explore.
