Message

At Cyber Intel Service, I work on SDNexus, a surplus property management tool for states. It brings together Donee management, eligibility verification, property requests, communication, invoicing, and GSA compliance tracking and reporting.

Across my full-stack developer roles, I’ve contributed to products including SG Wireless’s IoT device management dashboard, Beadpay’s multi-asset payments product, and WODO NETWORK’s blockchain-based gaming platform. My work has also included enhancing dashboard functionality, contributing product improvements, and writing code for several blockchains.

As a freelance software developer, I develop web, mobile, and desktop applications, APIs, and frontend and backend refactors. I’ve also worked on AI projects involving text-to-speech and speech-to-text, and use scikit-learn to integrate machine learning algorithms into personal projects.
