Field notes for AI, data, and BigData builders.

Exploring the systems, patterns, and tradeoffs behind production-grade data and AI platforms. From pipelines to models, from streaming to distributed jobs, these are the notes I wish I had when I was in the trenches.

Writing from the machine room.

Deep dives, patterns, and real-world lessons from building systems that move, learn, and scale.

01

Evaluation, retrieval, and serving paths

How model-backed products depend on data quality, feedback loops, and operational discipline.

From EMR Escalations to AI Platform Reliability

A practical bridge from big data escalation work to AI platform reliability: the same habits show up in scheduling, observability, data quality, and recovery.

Observability Before Orchestration

Orchestration helps only after the system can explain itself. Metrics, traces, logs, and workload shape need to come before automation confidence.

SLO Thinking for Data Pipelines That Feed AI Systems

Data pipelines need reliability language too. Freshness, completeness, latency, correctness, and recoverability are better signals than green checkmarks.

The GPU Cluster Has a Data Problem First

The expensive part of an AI platform is not only the accelerator. It is the end-to-end path that keeps training and inference workloads fed, observable, and recoverable.
