AI engineering by Roko Grga

AI systems.
Tested in public.

I build agentic workflows with a full-stack development background: bounded context, validated outputs, controlled execution, and evaluations that expose the limits.

Primary showcases

Code, controls, and outcomes
01Prototype

Frontend Director

AI-powered React editor with bounded context, validated edits, user approval, and reversible history. Structural additions separate read-only planning from approved execution.

Context
Selected JSX / bounded source
Controls
Patch validation / stale-plan rejection
Evidence
125 automated tests / atomic history

02Deployed

BTC–Jev

A deployed AI decision experiment with scheduled market processing, deterministic guardrails, limited model requests, and a public evaluation dashboard. Paper-only; no real orders.

Decisions
Candidate gating / long-only paper policy
Controls
Daily request reservations / pause switch
Evaluation
Simulated fills, costs, and outcomes

03Experimental

Problem Hunter

An AI research pipeline with source-backed findings, structured evaluations, caching, cost controls, and audit reports. Findings need human review; reliable autonomous opportunity discovery is not established.

Evidence
Attributed source passages / dates
Controls
Request ceilings / per-run cost limits
Outputs
SQLite ledger / JSON and Markdown

Frontend Director is a development prototype without a build-before-apply gate. BTC–Jev keeps archived direction forecasts separate from current paper results. Problem Hunter's general remedy research requires a reviewed workflow brief.
