Workflow Automation & Rule Engines
Design and implementation of queue-based worker systems, retry and idempotency patterns, rule and permission matrices, Sieve scripting, n8n workflows, Telegram and Discord bots, MCP servers, and Claude Agent SDK integrations.
Security & Server Hardening
Implementation of OAuth gateways, least-privilege principles, secrets management with SOPS, input validation, server hardening via Ansible, key-only SSH, fail2ban, Cloudflare traffic filtering, and SOPS-encrypted secrets with nightly backups.
AI Agent Systems
Building long-running TypeScript daemon-based AI agent systems with worker queues, Telegram and Discord integrations, memory services, sandboxed tools, and adversarial test suites.
Frontend Prototyping (Next.js)
Development of Next.js frontend prototypes and sites, including integration with backend APIs and deployment pipelines.

Project history
Co-founded a studio building made-to-measure software and AI integrations for businesses without a development team. Responsible for its direction and offer. Built and maintained the Next.js site, a Telegram bot with an HTTP API, Ansible-provisioned servers and deployment, outreach pipeline and Notion CRM. Built an OAuth gateway for AI agent workspaces, hardened company servers in Ansible, and built a Python proof of concept estimating private company revenue from cited evidence.
Technical project manager from March 2026 for Gateway Yield, a yield layer on Mellow Core Vaults. Led full AAVE V2/V3 integration end-to-end including smart contract development, backend, frontend, deployment, and team enablement. Customized push and async oracle development including Uniswap-dependent calculation oracles and Chainlink VRF oracle. Fullstack engineering across smart contracts, React frontend, and Go backend operator services for a DeFi yield product. Architected the internal multichain Hardhat V3 deployment template. Deployed Iden3 for an identity-system demo for a Big Tech company.
Helped design and implement ERC20 and ERC721 contracts for Wirex Pay cards and on-chain payments; built its Next.js frontend prototype.
