Four kinds of system, built end to end.

Every engagement runs 3–6 months, 2–3 days a week. I scope, I write the code, and I hand the working system to your team before I leave. AI is how I ship all of this with radically less project weight than traditional delivery required.


01

Workflow automation & internal tools

The system layer between your people and your tools. Internal apps and automations that replace the manual glue holding the operation together.

Python n8n Retool
02

Reporting & data infrastructure

Pipelines the team trusts and dashboards that replace the monthly Excel rebuild. The reporting you keep promising to fix, finally fixed.

ETL Warehouse BI
03

AI-enabled operating layers

Agents, extraction, classification, and copilots, added where they carry real operational weight. Not demos, not pilots.

Agents LLM tool-calling
04

Embedded build capacity

A senior builder inside your team for a defined window. Scoping, shipped code, and capability transfer. AI is the reason one person can carry this load.
