Jay Greasley
I build things,
then I help people
use them.
Technical support engineer and full-stack developer with 15+ years across startups, government, legal, and enterprise. I learn fast, build pragmatic solutions, and bridge the gap between engineering and customers.
What I bring
Build Products
NextJS, React, TypeScript, C#, Ruby on Rails. I build full-stack applications from scratch — currently a bespoke CRM handling real events and real members.
Support & Debug
Deep experience in technical support engineering at InfluxData, Demandbase, and ScreenCloud. Distributed systems, databases, cloud infrastructure — I trace issues through the full stack.
Bridge the Gap
The rarest skill in tech: understanding both how products are built and how customers use them. I turn customer pain into product improvements.
Current focus
Ceroc CRM
Bespoke event and member management system. NextJS, C#, Azure, SQL Server. Claude API integration for intelligent data workflows.
This Site
A living portfolio of technical experiments and spikes. Each one is a real thing I built to learn, not a tutorial I followed.
