I build AI agents
that don’t just sound
smart.
They are reliable.

I design and ship agentic AI systems — combining LLMs with agentic retrieval, knowledge graphs and continuous evaluation — that deliver trustworthy, evidence-based results in high-stakes, regulated domains — healthcare, finance, legal and enterprise knowledge.

SCROLL TO EXPLORE

Why “just an LLM”
is not enough

Large Language Models are trained to predict text, not truth. They can be confidently wrong, especially when the cost of error is high.

Hallucinations

Even 2026 frontier models hallucinate 4–19% depending on the task — citation accuracy is the worst offender.

No domain grounding

Built-in search is generic. Your domain knowledge isn’t in the weights — it needs governed, traceable retrieval.

No grounded verification

The model can’t check its answer against your data, policies and sources. That check has to be engineered.

Unsecured autonomy

Prompt injection, over-permissive tools, irreversible actions. Agents need sandboxing, permissioning and human-in-the-loop.

WHY IT HAPPENS

A simple truth from information theory

Models learn P(text), but we need P(true | text). These are not the same.

Even a perfect model will hallucinate because of uncertainty, compression and noisy data.

P(text)

We need

P(true | text)

=

P(hallucination) > 0

Always hallucinate.

The world is complex. Context is limited.

Models compress knowledge.

Compression creates uncertainty.

Uncertainty leads to hallucinations.

THE SOLUTION

Systems, not models.
Evidence, not guesses.

I build agentic architectures where the LLM is just one component. The agent plans, retrieves, self-checks and retries — every answer is grounded in data, verified, and fully traceable.

1. Plan & Retrieve

The agent decomposes the task and searches trusted sources and tools (MCP)

2. Ground

Knowledge graph links entities, relations and rules — curated context, not a dump

3. Verify & Retry

Self-check loop: fact-checking, contradiction detection, corrective re-retrieval

4. Guard

Least-privilege tools, sandboxed execution, prompt-injection defense, human approval for irreversible actions

5. Generate

LLM generates answers grounded in validated evidence — with guardrails

Evidence-based Answer

Citations, confidence scores, and full tracing of every step and tool call

PRODUCTION READINESS

Secure by design.
Operated like real software.

An agent in production is a security surface and an operational system — not a demo. I design for both from day one.

Security & Governance

  • Least-privilege tool access & permissioning
  • Human approval for irreversible actions
  • Sandboxed execution environments
  • Prompt-injection & memory-poisoning defense
  • PII controls and full audit logs

Aligned with the OWASP Top 10 for Agentic Applications (2026).

Production Operations

  • SLOs, model routing & fallbacks
  • Canary releases and instant rollback
  • Cost budgets and drift monitoring
  • Regression evals on every change
  • Multi-turn agent evals with repeated trials — errors compound along the trajectory

Evals practice follows Anthropic’s guidance on agent evals (2026).
