Over a decade of Data/ML Engineering Experience, and now with AI, you get three of me for the price of one! So you've got a lot of data and now you want AI agents and harnesses, vector databases, RAG, insights, complex integrations? Reach out to me. Seasoned in Python, all types of databases, and all of the AWS data/ML stack technologies. I thrive on cost reduction through efficiency and automation in complex environments. My expertise is in architecting and implementing cloud based solutions for tough problems for my clients . If you have a lot of data, and need to figure out how to store it, move it, automate it, or analyze it, and want to do it in AWS, then I'm your man. I cut my teeth in AWS and Python spending 7 years building the backend and analytics platform for an algorithmic trading fund, where the priorities revolve around latency, scale and real-time number crunching. Within Python I'm usually building or fixing systems, automating some type of workflow, or doing analytics using Boto3, Pandas, PySpark, SQL Alchemy, Airflow or the AWS APIs. Within AWS I'm most familiar with CDK, Aurora, Redshift, Lambda, OpenSearch/Elasticsearch, EMR/PySpark, Dynamo, ECS/Fargate/EC2 (Docker), S3.

Driven and self-reliant software developer with a robust background in IT, and proven communication skills. Brings a wealth of experience in the managed IT, reprographic, manufacturing, and library industries. Known for sharing insights gained from this background to improve operational maturity. I'm skilled at bringing technological solutions to business problems.

I'm the engineer teams bring in to build the thing and to own everything around it. Blank repo to running product: the mobile app, the API behind it, the infrastructure under that, and the pipeline that ships it all. I don't hand off the hard parts. Most of what I've built, I built from the ground up for clients and for my own products (I run a small software studio and ship my own apps). I like doing it right the first time: scalable, maintainable, and documented well enough that the next person isn't cursing my name. What I can help with: Build a mobile or web app from scratch: Flutter, React Native, Next, Vue Design and build APIs, backends, and microservices: Laravel, Node and beyond Stand up cloud infrastructure, CI/CD, and DevOps automation Rescue a stalled project or put out a production fire Be the versatile senior generalist your team's been missing If you need someone who can take an idea from nothing to shipped, or drop into an existing team and be the piece that was missing, let's talk.
