Third-year CS student. Accreva developer intern. Elvyna founder. Four AI systems built with shipping speed and real proof.
Governance
Risky AI output gets caught
RAG
Answers cite source pages
Ledger
Every write leaves proof
INPUT
Messy problem
ROUTE
AI orchestration
OUTPUT
Working system
Architecture pattern
Deterministic rules own every write. AI decides the route. Humans confirm before commits.
Proof wall
Each card shows the problem, the system built, the proof available, and the privacy boundary.
AI can't touch a ledger unless deterministic rules stand between model output and the database. Every mutation needs an owner, a scope, and an immutable trace.
Backend core
Phase B done
AR/AP
Phase C active
A plumber on a job site doesn't pick up. The caller hangs up. That call was $800 of work. Multiply by five missed calls a week. That's the problem Elvyna is built for.

A confident wrong answer in a classroom is worse than no answer. Most AI tutors have no mechanism to refuse or cite sources. They just talk.
Citation accuracy
85%
Correct refusal
100%
SAP environments have approved T-codes, vendors, and policy constraints that a generic LLM doesn't know and can't enforce. One hallucinated T-code in an AI output creates an operational incident.
Catch rate
