Engineering Case Studies

Each write-up covers the problem, the constraints it ran under, the decisions taken with the alternatives rejected, measured results, and an explicit statement of what was mine versus shared.

Agent systems

4

Agents with real tools, real context, and the evaluation that keeps them honest.

LLM Evaluation Platform

An OpenTelemetry and Langfuse platform that gates every prompt, model, agent, and tool change on measured accuracy, latency, and cost.

Sentinel Test Generation Agent

A multi-step agent that writes test cases from tickets, grounded in a code graph — and refuses to let untested work proceed downstream.

Retrieval & context

3

Grounding answers in knowledge that is scoped, current, and measurable.

Knowledge Graph RAG

Tenant-scoped retrieval over a million-plus entity knowledge graph, with a five-layer failure taxonomy so a bad answer can be traced to its cause.

Platform & reliability

2

The infrastructure agents run on, and the failures that had to be root-caused.

Code Intelligence Gateway

A code-search service for agents, taken from container proof of concept to serverless production — then rescued from a storage-throughput failure that no amount of application debugging would have found.
