Peramanathan Sathyamoorthy
AI-native product / agent engineer
Available now. Stockholm, Sweden. Open to AI-native product or agent roles, and to senior fullstack roles where using AI is already part of the job.
React and Node are common. What is scarce is shipping an agentic workflow in production with product taste, evals, and the judgment to keep a demo from becoming a liability.
What you are hiring
At Oneflow I owned public API, CRM clients, permissions, and an in-place JavaScript and Flow move to TypeScript, and I led a team. After December 2024 I did family care and shipped my own systems. The named products on this page are the March to August 2026 slice of that stretch, not lab employment.
I have landed a product in other companies' tools
At Oneflow I built CRM clients and a public API so the product worked inside HubSpot, SuperOffice, Salesforce, and Microsoft Dynamics. Permission models were theirs, not a demo embed.
An agent is a control loop, not a chat box
collab-finder is a local Tauri app. Cost, fit, rate limits, and a human promote before anything becomes permanent. The prompt is the cheap part.
I design for when not to call the model
If a signal is not worth the spend, the loop stops. Refusal is cheaper than a clever completion that should never have run.
One data source, so tools cannot drift
This site and the apply PDFs read one cvdata file. Role-fit packs do not silently fork the master record.
I modernize a living codebase in place
At Oneflow I moved a FlowType and JavaScript SaaS toward TypeScript with a history-preserving script. Type errors dropped about 70 percent. That saved more than 200 hours versus a rewrite.
I go below the web stack when that is where it breaks
Tamil metre analysis is a Rust parser compiled to WASM so it runs in the browser. collab-finder is a local Tauri app with SQLite, not a hosted chat UI.
The long arc from 2015 orchestration to 2026 local agent work lives in Essays.
Evidence
December 2024 to present is family care plus shipped products. The chronology is on the CV. This page sells from sourced metrics and artifacts.

Academic
The Uppsala master's ran from 2010 to 2016. I stayed with the thesis a bit longer through a personal interval — marriage, settling in — then published it as a conference paper and a journal article.
