You will get a fractional senior engineer for monthly code & architecture reviews
Project details
Need senior engineering judgment on tap — without hiring a full-time staff engineer? Keep me on monthly to review your code, architecture, security, and reliability, and be the experienced second opinion on decisions that are expensive to get wrong.
Each month you get hands-on review and async advice — design and PR reviews, architecture and security passes, and straight answers on tradeoffs — plus a written advisory report: what I found, rated by priority, with concrete recommendations. Essentials is a senior sounding board (~4 hrs); Standard adds a deeper architecture & security review and a roadmap (~8 hrs); Partner adds critical-PR review, a reliability deep-dive, and priority async access (~16 hrs).
Why me: I placed 1st of 116 in a security-audit competition, and I build and ship production systems myself — full-stack web apps (Next.js, Rails) and Solana programs. So I advise as someone who writes and breaks the same code, not from the sidelines. Stacks: JS/TypeScript, Ruby on Rails, Python, Rust.
Each order is one month; re-order to keep me on — no lock-in. Fully async. Receipts: rectorspace.com · github.com/rz1989s. Message me your stack for a fit check.

About Rheza
AI Agent Engineer on Solana | Audit-Proven | RECTOR LABS
Bekasi, Indonesia - 3:09 am local time
I don't build chatbots that get stuck. I build agentic systems that survive mainnet: LLMs that orchestrate real on-chain actions, agent privacy infrastructure, multi-chain stealth tooling. Every line of agent code I ship is audited like a smart contract — because that's what agents are: programs with money and autonomy.
What I build:
- Production agentic apps — LLM tool calling, multi-step reasoning, auto-recovery, preflight simulation
- Agent infrastructure on Solana — REST APIs + skill files for AI agents to consume on-chain primitives
- Solana programs — Rust + Anchor, audit-grade architecture, on-chain logic that survives mainnet
- Agent privacy — stealth addresses, viewing keys, Pedersen commitments across 17 chains
- Smart contract security — vulnerability hunting, audit reports, mitigations (13 findings across 14 audited Solana repos)
Proof of work:
- Sipher — Privacy-as-a-Skill for Multi-Chain Agents (66 endpoints, 17 chains, on-chain Anchor program, 1,402 tests, live in production)
- Kami — AI Co-Pilot for Kamino DeFi (plain English → signed mainnet tx, LLM auto-recovery, live on Solana mainnet)
- 11 hackathon & bounty wins — $36,050+ across the Solana ecosystem
- $10K Solana Foundation grant + $6K audit subsidy for SIP Protocol
- 1st of 116 in a Solana Security Audit — 13 findings across 14 repos, incl. a framework-level Anchor CPI bug (CVSS 7.5, fixed upstream)
How I work:
- Production-first — every line written as if it ships tonight, audited tomorrow
- Fully async — written updates + Loom walkthroughs by default. I'm in Jakarta (UTC+7); async keeps us both unblocked across time zones. Saves you status meetings, gives me deep focus.
- Honest comms — clear timelines, no scope creep, no ghosting
- Security-conscious — agents move money, so the bar is high
- Pragmatic — I ask questions before coding, pick the right tool, and say "no" when a feature doesn't serve the goal
Stack: Solana, Rust, Anchor, TypeScript, Next.js, Vercel AI SDK, MCP, Noir (ZK), Python, Docker, PostgreSQL
Let's ship a production agent — for your DeFi protocol, your trading desk, your DAO treasury, or whatever else needs to be smart, secure, and on-chain.
