AI automation and audits for teams running LLMs in production.

I automate manual work with AI agents, then audit your AI systems for security holes and margin leaks. I have spent 8+ years building production backends in Python and Go, so the fixes ship as working code, not slide decks.

AI automationSecurity auditsMargin audits

Three services, one goal: AI that is safe and pays for itself

Each service has a fixed scope, a written deliverable and a way to verify the result.

Service 1

AI Automation

AI automation replaces repetitive manual work with LLM agents and event-driven pipelines that run without supervision.

  • Voice, document and ticket processing at volume
  • Multi-agent workflows with queues, retries and fallbacks
  • RAG services with their own scaling and monitoring
  • CI/CD and incident automation using the Claude API

You get: a working pipeline in your cloud, runbooks, and an evaluation set to track quality.

Service 2

AI Security Audits

An AI security audit finds how your LLM application can be abused, such as prompt injection, data leaks and over-permissioned agents, before an attacker does.

  • Prompt injection and jailbreak testing
  • PII and secrets exposure in prompts, logs and outputs
  • Tool, API and agent permission review
  • Mapped to the OWASP Top 10 for LLM Applications

You get: a findings report ranked by severity, fix guidance, and a retest of the fixes.

Service 3

AI Margin Audits

An AI margin audit shows what each AI request really costs and where your gross margin leaks, then cuts that cost without hurting quality.

  • Token, model and infrastructure cost per request and per customer
  • Model routing, prompt caching and batching review
  • Cheaper fallbacks and graceful degradation under load
  • Cost and hallucination dashboards your team keeps using

You get: a cost breakdown, a ranked savings plan, and the changes implemented if you want them.

Sample audit finding formatIllustrative, not client data
AreaFindingSeverityFix
SecurityAgent can call a write API with no approval stepHighScoped credentials and human approval for writes
SecurityCustomer details written to prompt logsHighRedact before logging, shorten retention
MarginSame large model used for simple classificationMediumRoute easy requests to a smaller model
MarginLong shared prefix recomputed on every callMediumEnable prefix caching
AutomationRetries re-run the whole pipelineLowRetry individual steps from a queue

Every audit ends with a report in this format, plus a retest after your team applies the fixes.

How an audit works

A typical audit takes a few weeks, depending on how many systems are in scope.

Step 1

Scope and access

We agree which AI systems, data and costs are in scope. I work from read-only access and your existing logs and billing.

Step 2

Audit and measure

I test the system, trace the cost per request, and rank every finding by impact and effort.

Step 3

Fix and verify

You get the report. I can implement the top fixes with your team and retest so you can see the improvement.

About Mohit Kumar

I am a Lead Software Engineer with 8+ years building distributed systems in Python and Go. Since 2024 I have focused on production AI: multi-agent systems, RAG pipelines, LLM observability and AI-assisted engineering for teams of engineers.

I started auditing AI systems because most failures I see in production are infrastructure and design problems, not model problems. Unsafe permissions and wasteful token spend are the two I see most.

Questions people ask

What is an AI security audit?
It is a structured review of an LLM-powered system to find ways it can be abused: prompt injection, leaked personal data or secrets, and agents with more access than they need. You receive a ranked list of findings and fixes.
What is an AI margin audit?
It measures what each AI request costs across model tokens and infrastructure, compares that with the revenue it supports, and finds savings such as cheaper model routing, prompt caching and batching.
What can AI automation handle?
High-volume, repetitive work with clear inputs and outputs: processing calls and documents, triaging tickets, reviewing code changes, and responding to incidents. Anything risky keeps a human approval step.
Which stack do you work with?
Mainly Python and Go on AWS, with the Claude API, OpenAI, LangChain, CrewAI and Google ADK. I fit the audit to your existing cloud and tools.
Do you work with international teams?
Yes. I work remotely with teams in any time zone.
How do I start?
