Staff Software Engineer and Distributed Systems Architect with 20+ years of experience. Author of "Hadoop with Python" (O’Reilly Media).

I specialize in scaling mission-critical data platforms and high-availability backend systems. Recent highlights:

- Architected a cloud-native agentic AI platform using Gemini 2.5 and custom MCP servers (sub-5s latency).

- Built a 15TB+ biomedical graph platform on AWS, reducing infra costs from $100k to <$10k/month.

- Engineered a 60TB NoSQL clinical discovery platform with 1-second p99 query latency.

- Scaled engineering organizations from founding hire to 20+ developers and $4M+ ARR.

Seeking Staff/Principal Engineering, Engineering Management, or Principal Architect roles. I thrive in high-growth environments where technical strategy meets deep execution.

Aventic AI | aventic.ai | DevOps/Platform Engineer | Hybrid, Baltimore, Boise, USA | Full-time

Aventic is trying to change the way people talk with companies. We’re building an intelligent platform with custom LLMs and deploying them in the cloud and on-premise. We’re looking for someone who enjoys working with Kubernetes in the cloud and deployed locally on-site; enjoys autonomy and is able to take large features from conception to deployment; and wants to be able to have a large impact on an early stage product.

You’ll work on automation, observability, CI/CD, and infra-as-code; and partner closely with product and engineering teams to ensure reliability and velocity. Tech stack: LLMs, Javascript, Python, Node, React, Ruby, Kubernetes, Terraform, GCP

Ideal experience: - 3+ years in DevOps/SRE/Platform roles - Cloud infrastructure (GCP) - Infra-as-code (Terraform, Ansible, etc.) - Kubernetes and container orchestration - Strong Python - Bonus: Experience deploying Kubernetes on-premise

We’re a small, fast-moving team with experienced founders and strong product traction. Join us early and shape the foundation.

My wife has accepted a position in Wiesbaden, Germany and I am looking to continue my career. We will be moving mid August and I am an engineer with over 10 years of experience across a broad set of skills in software engineering, system architecture, and solutions engineering. Recently, I have focused on Hadoop engineering and have been involved in a number of production and research projects. Previous experience includes mining larges sets of vulnerability data from computer networks to determine trends and discover new attack vectors. Current focuses are developing Big Data analytics and applications on large multi-node clusters utilizing Pig, Java MapReduce, Zookeeper, Accumulo, Mahout, and Greenplum.

I also love learning new things and tackling hard problems, so I am open to learning languages and creating interesting products.

I have to agree, my largest gripe with the app store is searching for an app. When I look for a decent app, I currently google for app reviews, then go back to the app store find it by name and download it.
