Freelance Software & AI Developer

Software and AI
for e-commerce operations.

I build internal platforms, data pipelines, and Amazon advertising software for e-commerce teams.

Background

My work started in e-commerce. I learned the operations side first, and the code after that. Today I build the software for the problems that I used to solve by hand.

I work on both sides of a project. I can read a profit and loss statement, and I can read a stack trace. Most of my work sits between the two.

Work

AI platforms

I led an internal AI platform on the Claude Agent SDK, from the first idea to rollout for more than 15 employees.

It carries skills, a shared memory, and custom MCP servers.

Amazon Advertising

I managed a six figure monthly ad spend on Amazon Ads and Amazon DSP.

  • Seller Central
  • Selling Partner API
  • Advertising API
  • Marketing Cloud
  • Amazon DSP

Business intelligence

I build dashboards and reporting dataflows in Power BI, on top of the data that a business already has.

The numbers update on a schedule. Each view answers one question.

Custom applications

I build applications for work that a spreadsheet cannot hold.

One example is an internal ERP application for logistics, product management, and dashboards. Each application fits the process that it replaces.

Data automation

I connect APIs, databases, and files into one data pipeline, with Airbyte and PostgreSQL.

The pipeline runs without a person. If a source changes, the pipeline reports the error.
