You will get a working first version of your custom AI product
Project details
I will turn your product idea, requirements, or existing prototype into a working first version built around one primary user journey.
The package covers one web-based AI product with up to three connected workflows, ten core screens, two user roles, three external integrations, one AI or tool-using agent system, business rules and approvals, staging deployment, acceptance testing, source code, and handoff documentation.
This is a good fit for SaaS products, internal platforms, marketplaces, fintech decision tools, and agent workflows that need rules, approvals, permissions, or human handoff. I have built full-stack AI and financial products for major crypto exchanges and digital banks in security-sensitive environments.
Message me before purchasing with the product idea or current prototype, intended users, integrations, deadline, and first-version priorities. I will confirm what fits and define the acceptance criteria with you.

About Elijah
AI Software Engineer | AI Agents, Full-Stack SaaS & API Integration
Tempe, United States - 4:42 pm local time
🚀 I design and build full-stack AI software, AI agents, SaaS products, marketplaces, internal tools, and API integrations for business operations.
Stack: Next.js, TypeScript, React, Node.js, Python, FastAPI, Supabase, PostgreSQL, OR-Tools, OpenAI API, and other LLM APIs.
🧠 I’m strongest in the messy middle: when you know there is a valuable customer or operational problem, but the right workflow, architecture, controls, or product path are still unclear.
🛠️ I can take a project from customer discovery and product strategy through system design, UX, frontend and backend development, AI and API integrations, testing, staging, documentation, and handoff.
🎯 BEST FIT
• AI agent development and tool-using business workflows
• Full-stack AI SaaS products and internal tools
• AI integration and workflow automation
• Voice AI for calls, qualification, booking, and human handoff
• Fintech, payments, and decision-support tools
• AI products that need debugging, finishing, or rebuilding
✅ SELECTED WORK
• GridSynapse: A public AI compute procurement product built with Next.js, Python, FastAPI, Supabase, and OR-Tools. It helps buyers compare compute options and prioritize faster availability or lower cost.
• Treasury Router: A governed HNWI investment workflow I prototyped, designed, and built while working with Gate. It supports controlled routing, prepares client and advisor materials, records human approval, and includes an x402 testnet payment proof.
• Orelis: A commercial voice AI agent for inbound calls, customer intake, lead qualification, booking, structured summaries, and human handoff. Production telephony and CRM workflows are configured for each client.
• Monarch Doctor: An open-source CLI and CI preflight for AI agent payment code. It catches supported x402 payment patterns when a required policy guard is missing and can stop a release before it ships.
🔒 FOR SENSITIVE WORKFLOWS
For financial and sensitive products, I build in clear rules, approval steps, spending limits, and human review so important actions stay controlled.
💼 ENGAGEMENTS
