What I'm looking for

I’m looking for fully remote roles in EST/Americas time zones where I can build end-to-end, real-time, data-heavy web applications across frontend, backend, APIs, and databases.

At Forward Thinking Systems, I build and maintain full-stack features for Engage360 and IntelliHub, enterprise fleet-monitoring and GPS-tracking platforms. I’ve delivered real-time React and TypeScript alert dashboards, role-based reseller permissions, asset migration flows, and security improvements.

Previously, I supported IoT and asset-tracking systems at KORE Wireless, modernized Java/Spring Boot banking microservices at APAP, and deployed mobile Core cloud solutions at Huawei. I’m comfortable owning a feature from the UI through APIs and stored procedures, working across React, TypeScript, Java, C#, Oracle, and SQL Server.
