Fractional CTO & Technical Architect

Part-time CTO for startups or companies that need senior technical leadership without a full-time hire: architecture, end-to-end ownership, IT management, cost discipline.

• —System architecture and technical roadmap
• —Distributed-team governance and vendor selection
• —Decision logs, runbooks and code-review standards
• —Cost discipline on cloud and tooling

I design complex multi-component IT systems. Microservice boundaries, schema design, deploy pipelines, documented cross-stack decisions.

• —Architecture review and incremental refactoring
• —Microservice boundary design
• —Schema design and data modeling
• —Deploy pipelines and multi-environment workflow

I build production AI systems: agent loops with per-task tool whitelists, multi-tenant MCP gateways, custodial signing-services, code-level guardrails, production-grade prompt engineering.

• —Single agent loop with per-job-type tool whitelists
• —MCP gateway between LLMs and external tools (request-id correlation)
• —Custodial signing-service with per-agent encrypted EOAs
• —Code-level guardrails (non-bypassable SELL GUARD)
• —Subscription/credit engine for autonomous agents
• —QA for non-deterministic outputs

Tuning live-production MongoDB and Postgres clusters with a focus on cost discipline and zero-downtime ops.

• —Cache-pressure analysis and index optimization
• —Complex aggregation pipelines
• —Backward-compatible schema migrations
• —Hot patches under pressure

I map traditional processes, identify friction points and design end-to-end digital replacements with audit trails.

• —Process mapping and gap analysis
• —State machine design and digital workflows
• —Audit trails and GDPR-aware logging
• —Self-service UX and document generation

Multi-chain (EVM + Algorand) smart-contract integration with gasless UX, account abstraction, soulbound tokens and audit-ready protocols.

• —ERC-4626 vaults, EIP-7702 / ERC-7821 sponsored tx, UUPS proxies
• —Soulbound tokens (ARC-19 + ERC-5192) with versioned IPFS metadata
• —Cross-chain via LiFi, HTTP payments via x402
• —Algorand: AlgoKit, algosdk, ARC-3/19, Pera Wallet
• —Privy + Wagmi + viem stack
• —Isolated signing-service with per-agent encrypted EOAs
