JinacodeSystems
AI-first engineering studio

AI systems that hold up in production.

We design, build and run voice agents, agentic workflows and retrieval systems — plus the platforms, data flows and guardrails that make them dependable. Senior engineers only, working software every week.

AI at the core

The demo is the easy 20%.

Most AI projects stall on the last stretch: evaluation, safety, latency and cost. That stretch is the work we specialise in. Every system we ship comes with all six layers.

Models

The right model for the job. Frontier APIs or open-source models, tuned to be fast, reliable and affordable to run.

Knowledge

Retrieval that stays grounded. Hybrid search, re-ranking and live re-indexing over your approved sources, with citations.

Agents

State-driven workflows, not prompt chains. Planning, branching, retries and tool use across your APIs and databases.

Guardrails

Bounded autonomy. Evals in the build, policy checks at runtime, and human checkpoints exactly where they matter.

Observability

Know why the AI did what it did. Every decision and action logged, versioned and replayable.

Deployment

Where your data needs it. Cloud, private cloud or on-prem — air-gapped if required.

How we engage

From first call to live in four weeks

A fixed path with a fixed scope and price. No open-ended contracts, no quietly growing costs.

Engagement models
  1. Day 0–3

    Scope

    One focused session to agree the goal, the success metric and the smallest first slice worth building.

  2. Day 3–7

    Join

    Engineers join your team, tools and meetings. Access, a plan and first working code inside a week.

  3. Week 2–4

    Ship

    New working software every week, shown in a live demo. You set the priorities.

  4. Ongoing

    Hand off

    Docs, tests and training so your team fully owns it. Keep us on or carry on alone.
