About

Customer-facing engineering, crypto infrastructure, and AI workflows.

How I moved from production troubleshooting into domain ownership, automation, and the Forward Deployed, Solutions, and AI PM work I want next.

The throughline

Customer problems → automation builder → AI systems

  1. 2022 · Technical Engineer

    Joined Fireblocks

    High-availability fintech. Blockchain transactions, APIs, wallet ops, policy behavior. Got fast at production troubleshooting and customer translation.

  2. 2023 · Wallet & DeFi domain owner

    Became Focal Point

    Ownership of complex domains. Identified gaps in product, wrote a wallet PRD that landed on the Q2 roadmap as a "quick win." The pattern became clear: recurring customer pain could become product feedback, tooling, and automation.

  3. 2024 · Senior Engineer / Automation Builder

    Senior + Automation

    Built reporting automation with n8n, a data warehouse, JS, and an LLM. 30-minute manual reports collapsed to about 4 seconds. Director-requested initiative, used across 50+ customer-facing reports.

  4. 2025 · AI Builder, technical operations

    Multi-Agent Builder

    Shipped TRBT: around 20 specialized AI agents, 9 product domains, structured playbooks, and outputs that always cite their sources. A 7-person support team uses it daily. Inherited the off-exchange focal seat from someone who left "really big shoes to fill" and carried the work forward.

  5. 2026 · Looking outward

    Now

    Multi-agent systems work when they start from real operational pain. The next step is taking that approach into a commercial role where customer discovery, technical depth, and practical AI workflows meet.

About

A bit more, in my own words

I'm Ben. I started at Fireblocks four years ago close to the customer and close to the product: wallets, transactions, policies, integrations, and the parts that fail in interesting ways. The work taught me to translate fast: from confused customer reports to precise reproductions, from log noise to root cause, and from recurring pain to product gaps worth writing up.

Somewhere along the way I stopped wanting to repeat the same investigation twice and started wanting to build the workflow once. So I built things. n8n pipelines that retired manual reports. A reporting job that cut 30 minutes of SQL to 4 seconds of automation. Then TRBT, a multi-agent investigation system that helps reproduce the path an experienced teammate would take, with faster source-backed handoffs.

Now I'm looking outward. The same approach carries over well to roles where customer discovery, technical depth, AI workflow design, and measurable value sit together: sales engineering, GenAI engineering, AI product. Fintech, web3, payments, and crypto custody are domains I've already spent years inside. If that sounds like the seat you're hiring for, I'd love to talk.
