# Eli Benbaruk — ELI/OS (detailed)

> Forward Deployed & AI Engineer. Engineering student @ESILV. I make companies AI-native and build autonomous multi-agent systems and on-chain protocols — software that acts, not just answers.

I've been building production software since I was 14. I've designed and deployed multi-agent systems, AI infrastructure and on-chain protocols. 4× hackathon winner.

## Projects — case studies

### Heureka (2026)
- Tagline: An AI co-scientist — 7 agents that generate, refute and rank hypotheses.
- Problem: Research is bottlenecked by how many hypotheses a team can generate and seriously test. How do you surface testable ideas you wouldn't have had?
- Approach: 7 specialised agents in an adversarial loop: generation (expert debate) → critique → falsification (red-team) → safety → Elo tournament ranking → evolution. Claim-level verification: each hypothesis is broken into atomic claims checked against open-access literature (OpenAlex, Europe PMC, arXiv); conjunctive scoring — a single contradicted premise collapses the score.
- Impact: Ranked hypotheses with claim graphs, calibrated novelty scores, falsification verdicts and proposed experiments. Budget-driven orchestrator, per-role model routing, reproducible runs with provenance. Unit + integration tests, CI.
- Role: Sole author — architecture, agents, evals.
- Stack: Python, Pydantic, multi-agent.

### FendForItself (2026) — 🏆 Agentic Economy on Arc 2026
- Tagline: Autonomous AI-run companies spun up in ~30 seconds.
- Problem: Launching a micro-business takes dozens of manual steps. What if agents could own and operate a business end-to-end?
- Approach: Each generated company gets its own wallet, USDC funding and a priced API (x402-protected). Agents spawn, pay and coordinate on Arc.
- Impact: Winner, Agentic Economy on Arc 2026 (Circle + Arc + Lablab.ai). Demo: 60 buyer agents settling on-chain over real-time SSE. $0.005/call at ~98% margin — viable because USDC is Arc's native gas.
- Role: Solo build — agents, on-chain integration, frontend.
- Stack: Next.js, Gemini, x402, Arc.

### PACT (2026)
- Tagline: Identity & reputation for autonomous agents.
- Problem: Agents that transact need to prove who they are and decide who to trust, with no human in the loop.
- Approach: Three phases — cryptographic handshake (capabilities + Ed25519-signed bonds), discovery (need/capability matching), Web of Trust (referrals via bonded peers).
- Impact: 20+ REST endpoints, network visualization dashboard, two demos (one fully LLM-driven, one scripted).
- Role: Protocol design + backend + interface.
- Stack: FastAPI, React, Ed25519.

### onchain-lie-detector (2026)
- Tagline: Automated crypto due diligence via fund-flow graphs.
- Problem: Evaluating an on-chain protocol is slow, manual and easy to fake (inflated TVL, Sybils).
- Approach: Ingests 4 heterogeneous sources (Alchemy RPC, Dune, Etherscan, DefiLlama), builds a fund-flow graph, runs Louvain clustering + Johnson's cycle detection.
- Impact: 0–98 trust score across 5 weighted dimensions, 108+ tests. Replaces hundreds of hours of manual investigation per protocol.
- Role: Design + implementation.
- Stack: Python, graphs.

### zkrust (2026)
- Tagline: A Groth16 zk-SNARK built from scratch, zero crypto deps.
- Problem: Truly understand zero-knowledge proofs — not just call a library.
- Approach: Full Groth16 over BN254 — hand-rolled Montgomery arithmetic (Fp/Fp2/Fp6/Fp12), optimal Ate pairing, Pippenger MSM, KZG commitments, radix-2 NTT. CLI setup → prove → verify.
- Impact: ~6,500 lines of Rust, 159 tests, 6-crate workspace. ~1 ms prove / ~13.5 ms verify (Apple Silicon).
- Role: Sole author — maths, implementation, tests.
- Stack: Rust.

### LiquidVest (2026)
- Tagline: Tradeable token vesting on Solana.
- Problem: Vesting tokens are locked and illiquid until the cliff ends.
- Approach: Each vesting schedule is a transferable Receipt NFT — selling the NFT sells the future token stream. Linear / cliff / step curves.
- Impact: Anchor 0.30.1 program, Node.js + better-sqlite3 indexer, Next.js frontend. Property-based tests (Proptest) + 13 integration tests (Bankrun).
- Role: On-chain program + indexer + frontend.
- Stack: Anchor, Solana, Next.js.

### HyperVest (2026) — 🏆 Hack'inDauphine 2026 (Tokenization track)
- Tagline: On-chain equity vesting with Soulbound Tokens.
- Problem: Equity vesting stays opaque, off-chain and hard to verify.
- Approach: Vesting anchored on non-transferable Soulbound Tokens, with performance-based unlocks (MRR, GitHub commits, KPIs) instead of pure time.
- Impact: Winner, Tokenization track (Kryptosphere). Solidity + OpenZeppelin v5, Foundry, deployed on HyperEVM Testnet.
- Role: Smart contracts + frontend (with Ariles Hireche).
- Stack: Solidity, HyperEVM.

### truth-stamped (2025)
- Tagline: Cryptographic anti-deepfake timestamping.
- Problem: Prove a piece of media existed at time T, in the age of AI deepfakes.
- Approach: On-chain timestamping — SHA-256 + ECDSA signatures + immutable record on Base.
- Impact: Live on Base Sepolia, 12 tests, ~$0.001 per stamp.
- Role: Design + implementation.
- Stack: TypeScript, Solidity, Base.

## Experience

### TVA Engineering — Forward Deployed Engineer (intern) · Antony (92) · Jun — Jul 2026
Embedded in an industrial engineering firm (~110 people) to make it AI-native. Designed and deployed the whole central AI infrastructure end-to-end: cloud (Claude API, reusable internal prompts & tools) AND a self-hosted local cluster — networked Mac Minis serving open-source models (Qwen, Gemma) routed per task. Re-architected access to a non-AI-ready ERP (BoondManager) via custom MCP servers, built an in-house ERP, shipped commercial tooling + a 360° leadership dashboard, Microsoft 365 automations. Result: dozens of hours/week saved, ~10 large clients won. Security, guardrails and tests throughout.

### Euretudes — AI Engineer (intern) · Paris · Jun — Sep 2025
Helped the company adopt AI and become agentic. Small custom agents per team (recruiting: sourcing, CV screening, profile formatting, follow-ups, scheduling) and drove adoption.
