Your AWS and AI systems work in the demo. I make them survive production.

I help engineering teams close the gap between “it works on my machine” and “we can trust it with real users, real load, and a real bill.”

For CTOs, founders, and platform teams facing rising AWS costs, fragile serverless systems, weak observability, broken RAG quality, or AI pilots that can’t safely reach production.

The demo-to-production gap

Real pain, not abstract architecture talk.

Most teams don't need more cloud jargon. They need to know what's expensive, what's fragile, what slows users down, and what can be safely changed this week.

Cost

The AWS bill is growing, but no one knows which system is causing it.

Finance sees the number. Engineering sees hundreds of services. Nobody has a safe first move.

I start with cost allocation, idle inventory, traffic shape, and commitment risk before touching architecture.

GenAI

The GenAI demo worked, but production quality, latency, and cost are unstable.

The feature looks impressive in a meeting and then becomes expensive, slow, or untrusted with real users.

I inspect retrieval, context design, evals, fallbacks, and cost per request before blaming the model.

Deploys

Deployments are risky and rollback is unclear.

Every release needs extra human attention. That slows the team and creates fear.

First I check blast radius, deployment path, stateful dependencies, and rollback ownership.

Observability

Observability exists, but debugging still takes hours.

Dashboards are present, but incidents still become log archaeology and Slack guessing.

I connect symptoms to traces, metrics, logs, ownership, and alarms that point to action.

IAM & envs

IAM and environments grew organically, and every change now feels risky.

Permission changes become production incidents waiting to happen, and nobody wants to clean them up.

I define account boundaries, environment contracts, permission guardrails, and IaC ownership.

Scale

The platform works today, but no one trusts it at 10x traffic.

Growth becomes a threat because failure modes, queues, database limits, and on-call paths are vague.

I model what fails first, then build guardrails around scale, retries, backpressure, and recovery.

What's included

  • Review across cost, reliability, latency, and rollback risk
  • Prioritized fix list: what to fix first and why
  • Focused AWS Cost & Reliability Audit when the bill is the symptom
  • Written findings you can hand straight to your team

Includes a focused AWS Cost & Reliability Audit when the bill is the symptom.

AWS Cost Audit

From $1,500 · plan in 7 business days

Teams whose AWS bill keeps climbing and nobody owns FinOps.

I find what your AWS bill is quietly bleeding and hand you the remediation plan. You keep the savings forever.

What's included

  • Line-item findings from your billing data, with the math shown
  • Remediation plan in priority order (quick wins first)
  • Right-sizing, commitments, lifecycle, and LLM token ceilings
  • Cost guardrails so the bill doesn't creep back

Also available: GenAI / RAG readiness review, implementation sprints, and fractional platform architecture.

Reference architecture

How a production GenAI request should actually flow.

A real RAG lifecycle on AWS: authenticated request, semantic cache, vector retrieval, guardrails, then a Bedrock call — every step logged, evaluated, and capped by a hard cost-per-request ceiling. This is the difference between an AI demo and a system you can trust with real users and a real bill.

About Rahul

I'm Rahul Ladumor, a Principal Cloud & AI Platform Architect from Surat, India. I work close to teams that already have real users, real AWS bills, integration constraints, andreal production pressure.

9+ years in cloud and platform engineering. AWS Professional certified. 4x AWS Community Builder. Production AWS + GenAI delivery across enterprise, SaaS, consulting, and AI-driven development work. I care about systems that survive traffic, failures, and late-night incidents.

Common questions

Asked before booking.

What kind of AWS architecture projects do you take on?

I specialize in systems that need to survive production: serverless migrations, AWS cost optimization audits (typically 30-40%, up to 55% documented), event-driven architectures on ECS/EKS, GenAI/RAG infrastructure on AWS Bedrock, and multi-account cloud security. My value is highest when you need reliability, security, and cost control at scale.

How much can you save on my AWS cloud costs?

Typical AWS + LLM engagements land around 30 to 40% when waste is structural: idle compute, wrong DB tier, unbounded model calls, missing lifecycle. On documented work, reductions reach up to 55%. I quote from utilization and billing data, not from a template. ₹50L+/year in AWS waste removed for clients (~$60K+/year), from cost and reliability audits.

What AWS certifications do you hold?

I hold three AWS Professional certifications (Solutions Architect, DevOps Engineer, and Generative AI Developer), plus AWS Developer Associate and HashiCorp Terraform Associate. I'm also a 4x AWS Community Builder (Serverless).

Can you help with GenAI / AI/ML infrastructure on AWS?

Yes. I build production GenAI systems on AWS Bedrock including RAG pipelines, AI agents, and LLM applications. I handle the full stack: vector databases, prompt engineering, token cost monitoring, and audit logging. Currently studying Agentic AI at IIT Roorkee.

Do you offer a free consultation?

Yes: a free 30-minute call. You describe what’s going wrong, I suggest what to measure first, flag obvious cost and reliability risks, and say if I’m a fit. No commitment. Book from the contact page (Cal.com) or email hello@rahulladumor.com.
