Arnas Treciokas

Software engineer and consultant. I help banks and lenders catch fraud, make better credit decisions and keep complex platforms running well.

About

I have spent around twenty years building software, and the last decade or so on the technical side of fraud prevention and credit decisioning for financial institutions across Europe, the Middle East and Africa.

I like the part of a project where design meets reality: architecture, integrations, upgrades, migrations to the cloud, go-live night and the quiet weeks after. I enjoy explaining complicated systems to the people who have to run them, and I lately spend a lot of time making that easier with AI-assisted tooling.

What I work on

Fraud & financial crime

Card fraud detection, identity resolution and network analytics for banks and card issuers.

Credit decisioning

Rules-based origination and decision services, with bureau and data-provider integrations.

Platforms & cloud

Solution architecture, version upgrades, on-premise to cloud migrations, hardening and performance tuning.

AI-assisted tooling

Agents and retrieval tools that turn product documentation and configuration into faster troubleshooting.

Toolbox

Projects & notes

Side projects, experiments and write-ups will live here.
