🎯 About Me

AI Platform & Solutions Architect with 9+ years building production AWS platforms, serverless backends, and GenAI infrastructure. I work best with teams running serious systems under multi-region, high-traffic, cost-sensitive, on-call reality — where reliability and governance actually matter.

Available for consulting and fractional engagements as an AWS cost optimization (FinOps) consultant, Amazon Bedrock / production RAG engineer, serverless & platform reliability architect, and forward-deployed AI engineer.

🌙 3:47 AM — the call I get hired for

Most engagements start the same way. Something is on fire, or the AWS bill stopped making sense, or a GenAI system is falling apart under real traffic.

I find what is bleeding, stop it, and make sure it cannot happen again.

Recent: a shared Redis pinned at 100% CPU with 1,620 open connections, degrading a specifications-indexing pipeline. Root cause: a KEYS * call in Lambda, no connection pooling, hardcoded credentials. I shipped a cost-neutral migration to a dedicated Valkey 7.2 cluster — with a full rollback path, credentials remediated.

I build systems that survive real traffic, real failure modes, and real cloud bills. Not demos. The boring, reliable kind that does not wake you up at 3 AM.

🎓 Education

🛠️ Four things teams hire me for

🤖 GenAI Infrastructure Bedrock & SageMaker pipelines built for real traffic. RAG, agent workflows, guardrails, and evals that hold up past demo day — chunking, embedding selection, reranking, RAGAS + LangSmith loops.

💰 Cost Control (FinOps) I find the spend your AWS bill is quietly bleeding and stop it. Token budgets, spend governance, right-sizing, S3 tiering, connection pooling. FinOps that actually sticks.

🏗️ Platform & Reliability Multi-region systems with proper observability, incident playbooks, and safe rollouts. Lambda Powertools, structured logging, tight IAM scoping to keep blast radius small.

🚀 Cloud Delivery Terraform, CDK, Kubernetes, CI/CD. Shipped fast, without breaking prod. Blue-green and canary by default, rollback planned before the deploy.

How I weigh a system: Cost — what does this become at 10x scale? Reliability — what happens when one component fails? Blast radius — how much breaks at once? Ops load — who maintains this at 2 AM? Time to ship — is this overbuilt? I prefer boring but reliable over clever but fragile. Every time. If something is a bad idea, I say it directly and explain the consequence.

❓ How I Can Help

Looking for an AWS cost optimization / FinOps consultant?

Yes. I run AWS cost audits and FinOps engagements that remove ₹50L+/yr of cloud waste — right-sizing, S3 tiering, connection pooling, GenAI token-budget governance, and spend guardrails that actually stick. → Book a call

Need an Amazon Bedrock / production RAG consultant?

I build production GenAI infrastructure on AWS Bedrock and SageMaker — RAG pipelines, agent workflows, guardrails, and LLM evaluations (RAGAS, LangSmith) that hold up past demo day, not just in a notebook.

Want a fractional cloud / platform architect for hire?

I take on fractional architect and consulting engagements — architecture reviews, multi-region reliability, AWS Well-Architected audits, and technical advisory. 9+ years, 3x AWS Professional, 4x AWS Community Builder.

Forward-deployed engineer for AI / customer-facing delivery?

I work forward-deployed — embedding with your engineers to take AI and cloud features from prototype to production under real traffic, real failure modes, and on-call reality.

AWS serverless or platform reliability help?

Serverless architecture (Lambda, API Gateway, DynamoDB, Step Functions, EventBridge), multi-region high availability, observability, and safe blue-green / canary rollouts with rollback planned before the deploy.


🤝 Work With Me

I'm open to consulting engagements and fractional architect roles — GenAI infrastructure, platform & reliability, and FinOps.

engagements:
  - GenAI infrastructure: Bedrock / RAG / agents, guardrails, evals
  - Platform & reliability: multi-region, observability, safe rollouts
  - Cost (FinOps): audits, governance, token + spend ceilings
  - Fractional architect: design reviews, technical advisory
preferences:
  remote: true
  timezones: IST + US
