Founder, GreenRoom · Production engineer

Building the graph behind culture.

I'm building GreenRoom so artists and creative teams can find the right people through verified work and real relationships.

I also help teams turn fragile AI and data prototypes into production systems with tests, observability, and explicit failure modes.

Consulting capacity is intentionally limited so I can stay hands-on from diagnosis through delivery.

How I build.

I work best where product ambiguity meets backend, data, and AI complexity.

Prototype to production

Turn a promising demo into a tested, observable system with explicit failure modes.

AI product engineering

Build bounded agent workflows, retrieval, tool use, evaluation, and clear human review paths.

Data and platform systems

Design FastAPI services, Postgres models, ETL pipelines, queues, and cloud delivery.

Technical rescue

Find root causes across contracts, data flow, infrastructure, and release discipline.

About

Founder first, engineer always.

I'm Eric Henschel, founder of GreenRoom. Before going all-in on the graph, I moved ESG data for 6,500+ companies at Bloomberg and distributed 100M+ parameter calibration workloads at Assured Guaranty. GreenRoom is built with that production discipline.

I design the data model, write the code, and ship it myself. When something breaks in production, I'm the one who answers.

Consulting, in limited capacity.

Alongside GreenRoom, I take on a small number of engagements for teams whose AI and data systems face launch risk: production triage, audits, and bounded delivery sprints. One senior engineer, end to end, no handoffs.
