Senior AWS Cloud & Product Engineer
I Personally Build Your AWS Infrastructure, POCs, and Production Systems.
35 years architecting for Fortune 500 companies. Now available for direct-build engagements — AWS infrastructure, AI/RAG prototypes, and TypeScript/Python product development. You hire me. You get me. No team, no handoffs.
Trusted by Industry Leaders and Innovators
Need Senior Engineering Work Delivered, Not Managed?
I work with founders, CTOs, and engineering leaders who need:
- •A production-ready AWS landing zone built right the first time — not duct-taped by juniors.
- •A working AI/RAG proof-of-concept (Bedrock/Claude) shipped in 2–4 weeks, not theoretical advice.
- •Senior infrastructure and product engineering capacity without a 6-month hire.
- •TypeScript/Next.js or Python development with architecture judgment baked in.
- •Someone who writes the CDK or Terraform, not just draws the diagram.
How It Works
A predictable, low-friction path from first conversation to shipped system — and a clean hand-off when the work is done.
Intro Call
30 min
We talk about what you're building and whether I'm the right fit. No pitch — a real technical conversation.
Scoping
Week 1
I produce a written proposal with scope, timeline, deliverables, and tech stack. You know exactly what you're getting before we start.
Build & Deliver
2–12 weeks or ongoing
I personally build your system — infrastructure, application code, CI/CD pipelines, documentation. You get senior work at every layer.
Handoff
Closeout
Clean documentation, deployed systems, and — if you're hiring a team — code your engineers can maintain.
You Hire Me. You Get Me.
Most agencies sell you a team. Freelance marketplaces sell you hours. I sell you direct senior engineering work — personally delivered, from architecture through deployment.
Every engagement is built and shipped by me — Ken Ramirez — with 35+ years architecting systems for Siemens, Carrier, Atlas Air, Fairbanks Morse Defense, Kubota, and more. I work with a small number of clients at any time, which means you get the focus and depth your build deserves.
Signature Specialty
AI/GenAI Prototypes That Actually Work.
Every founder wants to “add AI.” Most don't know where to start. I build working AI/RAG prototypes using AWS Bedrock and Claude — real systems that ingest your data, answer questions, and integrate with your product.
No vapor. No “we'll figure it out in production.” Just a deployed proof-of-concept in 2–4 weeks that proves the concept is viable — or shows you why it's not before you waste six months.
Engineering Outcomes at Enterprise Scale
Measurable results from production systems I personally designed, built, and shipped across Fortune 500 and private-equity-backed environments.
Connected building devices served by the event-driven, serverless TypeScript platform I built at Carrier (Abound BMS) — IoT Core, Lambda, DynamoDB/Timestream.
Uptime on the mission-critical, multi-region SaaS platform I architected and shipped for Siemens.
Infrastructure cost reduction I delivered through FinOps and architecture discipline on an enterprise SaaS platform.
Faster deployment cycles from the CI/CD pipelines I built and redesigned — GitHub Actions, blue-green releases, automated Vitest/Playwright gates.
Servers migrated to AWS at Atlas Air on the multi-account landing zone and migration tooling I designed and built (AWS CDK, Terraform).
Detection and response times from the security guardrails and observability I implemented across production environments (Security Hub, GuardDuty, CloudWatch/OpenSearch).
Insights for Builders and Technical Leaders
Perspectives on shipping AWS infrastructure, building full-stack TypeScript and Python products, and getting AI/RAG prototypes into production — written from the engineer who personally builds them.

Ready to talk about your build?
Let's talk. 30 minutes. I'll ask about your stack, your timeline, and what you're trying to ship — and I'll tell you honestly whether I'm the right fit.
