Services

Production-grade engineering services for ambitious software products

These pages are structured around the kinds of work I actually do: AI agents, grounded LLM systems, Solidity-backed products, Stripe reliability, and full-stack delivery across products with moving parts.

AI Agents

Production AI Agent Development

I build AI agents that do useful work in production: research, document operations, support workflows, internal tooling, and multi-step actions with clear failure modes. The focus is not on demo magic. The focus is reliability, observability, and operating cost.

Best fit
  • Founders building an AI-native product that needs more than a single prompt wrapper.
  • Teams replacing manual operations with multi-step agents that call tools, fetch data, and write outputs.

RAG Systems

RAG and LLM Systems Engineering

When an LLM needs to answer from documents, product data, or internal knowledge, the quality of retrieval and response policy matters more than model hype. I build grounded systems that can explain what they used, refuse when context is weak, and stay maintainable as the corpus grows.

Best fit
  • Teams shipping support, research, or knowledge workflows where citations and grounded answers matter.
  • Products with document ingestion, chunking, embeddings, vector storage, and retrieval debugging requirements.

Web3 Systems

Solidity and Web3 Product Engineering

I work on Web3 products where onchain logic changes how the system behaves and what users can trust. That includes escrow, token operations, smart accounts, settlement flows, and the offchain systems around them: APIs, operator tooling, audit trails, and execution workflows.

Best fit
  • Teams building escrow, token, DeFi, or operator-driven Web3 products with real business rules.
  • Founders who need backend and contract logic to move together cleanly instead of being developed in isolation.

Payments

Stripe and SaaS Systems Engineering

Payments are where weak backend design becomes expensive. I build Stripe-backed systems with the boring but necessary pieces done correctly: retries, idempotency, webhooks, reconciliation, operator visibility, and product flows that do not fall apart once real money is involved.

Best fit
  • SaaS teams launching subscriptions, invoicing, or account lifecycle flows.
  • Marketplace or operator products using Stripe Connect and payout orchestration.

Full Stack

Full-Stack Product Engineering

I work best on products with moving parts: frontend, backend, automation, payments, data, and AI features that all need to cooperate. The goal is not to ship fast at any cost. It is to ship ambitious products cleanly, with architecture that still makes sense six months later.

Best fit
  • Founders who need one engineer who can reason across product, architecture, delivery, and implementation.
  • Small teams that need backend-heavy delivery without losing frontend quality.
