Cloud & Infrastructure
AWS-certified infra — ECS/Fargate, Terraform and blue-green CI/CD that scales from zero and stays up.
Agentic AI & LLMs
Production AI — Claude agents, RAG and tool-calling that do real work, not demos.
Automation & Integrations
n8n workflows and event-driven pipelines that wire your tools together and run themselves.
Data & Analytics
Pipelines, ML and geospatial — from a Neo4j fraud graph to serverless map tiles.
Strategy & Delivery
Honest scoping, a clear statement of work, and delivery you can see through.
Deep AWS expertise, independently verified.
Credentials spanning architecture, security, data, machine learning and generative AI — each one links to its official AWS verification record.
Three people. Zero handoffs.
You work directly with the people writing the code. No account managers, no juniors learning on your budget.
