Gezim Veliu

Senior software engineer. I build .NET back ends and the mobile apps that run on them.

In 13 years I've shipped fintech apps, ride-hailing and delivery platforms, a border management system for Kosovo Police and an AI security platform for small businesses. Today I work on big-data eDiscovery software with .NET and SQL at ISA Consulting.

I love turning ideas into working software, especially where a careful back end meets an interface that feels good to use. Lately that means AI agents and LLMs on .NET.

Apps

Nineteen apps across fintech, security, mobility, delivery, health and government. Anything with an Open prototype button runs as a clickable prototype in the phone.

  • Cybee

    Live

    Cybersecurity and compliance for small businesses

    An all-in-one security platform for business owners who aren't IT experts. It stops threats on Windows and Linux devices with behavioral AI, watches cloud apps like Microsoft 365, Google Workspace, Slack and GitHub, and turns frameworks such as GDPR, SOC 2, HIPAA and NIS2 into one-click compliance reports, with an AI advisor to answer questions.

    Your bank of things

    A fintech app built on circular-economy ideas: snap a photo of something you no longer use, get an instant offer, get paid on the spot and ship it later. Earnings land on a free debit card, with carbon offsetting built in. I led application development here as tech lead.
