Get To Know Me
I'm Taylor Cressy, a Senior Staff AI Engineer.
I build AI and ML systems that operate at petabyte scale for millions of users, in real time. From architecting agentic AI platforms and real-time inference pipelines to the distributed data systems that power them, I work across the full stack. 12+ years in, and I still love the challenge of taking something genuinely hard and shipping it at scale. Chances are if you've got a problem, I've got a solution.
I built this site as a creative outlet, a way to own a full end-to-end suite of services and infrastructure. Everything you see (and don't see) is bespoke. Its primary purpose is to keep me entertained: a place to learn new things and work on whatever I find interesting. If you see something you like, be sure to reach out 😁
What I Do
Data Engineering
From real-time ingestion pipelines to batch systems processing petabytes of data, I build infrastructure that scales to any business need. Kafka, Spark, and cloud-native tooling are my go-tos, and I care deeply about getting the plumbing right before the models go live.
Service Oriented Architecture
Can't work in the backend without knowing how to build a proper RESTful API. I've designed and built microservices at scale across a variety of frameworks, Spring being a personal favorite. Clean contracts, reliable services, and systems that don't fall over under load.
AI & Machine Learning
I architect AI and ML platforms end-to-end, from feature stores and training infrastructure to real-time inference at sub-100ms latency. I've shipped agentic AI systems, built online learning pipelines that adapt in real time, and led MLOps ecosystems serving 50+ production models. LLMs, neural nets, and everything in between.
System Design
One of the most rewarding parts of this job is watching an architecture go from whiteboard to production. I've designed complex, high-scale systems across payments, fraud/risk, agentic AI, and real-time ML, and I genuinely love that part of the work.
Front End Development
While I spend most of my professional time in the backend, I love working across the full stack. My first jobs were actually in the front end and I still keep up with the cutting edge, this site included. React is my go-to, and I'm a firm believer that good UX matters even for backend-heavy products.
Dev Ops
Probably the skill set that my peers know least about. Almost a guilty pleasure. If you aren't automating it, are you really doing it correctly?
