Why teams hire me

I have sat on both sides of the deal: carrying a quota-adjacent seat (sales engineering, account management) and shipping the code that the customer actually runs. That is the job description of a Forward Deployed Engineer.

If you need a... What I bring Proof below
Forward Deployed Engineer Scope with the customer, build inside their stack, hand over something their team runs without me PumpWire, MyGrokFlow, TickerFront
GTM Engineer AI outbound and lead systems: research, enrichment, gated drafts, reply triage, CRM as the source of truth BDRclaw, MyGrokFlow
Sales Engineer Demos and POCs that survive technical buyers; I translate product to buyer and back SE + account management background, AgentToll and PumpWire x402 demos

🏆 Hackathons

I build under deadline and ship the proof, not the slides: agent payments, agentic finance and multi-agent pipelines.

COLOSSEUM · CRYPTO WORLD'S FAIR 2026

🛣️ AgentToll

Charge AI agents per request. Keep humans free.
A drop-in paywall proxy for any site, API or MCP server: set a price per route or per tool, and agents pay per call in USDC over x402 while people browse free. No API keys, no signups, no invoices; money lands straight in the founder's own wallet.

PAYPAL AI HACKATHON · DEVPOST 2026

💸 Payback.ai

An AI back office for businesses that run on PayPal.
Syncs PayPal activity, uses Cloudflare Clef decision models to pick the GL account, product line and risk for every transaction, books balanced double-entry journals, reconciles to the PayPal balance, and only acts (invoice reminders, payouts, dispute triage) when it is confident and policy allows. Otherwise it asks a human.

ANSEMHACK CLAWRENA · CLAWPUMP × PUMP.FUN

⚡ PumpWire · $PWIRE

pump.fun rug-risk scores, sold to other agents per call.
Watches every pump.fun launch onchain and turns it into a 0 to 100 rug-risk score with plain-English reasons. Agents pay $0.01 USDC per call over x402 or ask through an MCP server. Our buyer agent made 250 paid mainnet calls on launch day.

LABLAB.AI · AI AGENTS HACKATHON

🐦 Auto Tweeter

Tweets that write and post themselves.
An autonomous multi-agent pipeline that produces and publishes posts to X (Twitter) end to end. The judges recognized it for effective agent prompting, a habit I still build on: clear roles, tight instructions and checks between steps.

PumpWire, explained simply (click to expand)
  • The problem. pump.fun lets anyone launch a Solana token in seconds on a bonding curve (the price rises automatically as people buy). That speed also makes rug pulls easy: a developer launches, friendly wallets buy first, then everyone dumps on later buyers. A trading bot looking at a brand-new token can't easily see who deployed it, who bought first, or whether those early buyers are secretly the same person.
  • What PumpWire does. It watches every pump.fun launch onchain, stores launches, trades and wallet funding links, and turns them into a 0 to 100 rug-risk score with plain-English reasons (e.g. "3 buyers in the creation slot share one funding wallet"). The score is a deterministic, versioned, unit-tested function, so every number traces back to its evidence.
  • How agents pay for it. No API keys or subscriptions. It uses x402, a revival of the web's HTTP 402 Payment Required status code: an agent calls GET /v1/risk/:mint, gets a 402 with the price ($0.01 USDC), pays on Solana, retries, and gets the answer.
  • How agents plug in. It ships as an MCP server, so Claude, Cursor or a claw-agent can simply ask "rug check <mint>" and pay from their own wallet, with spending caps enforced before anything is signed.
  • Proof, not slides. Our own buyer agent (PWIRE Scout) made 250 paid mainnet calls on launch day. A public /live page and /v1/stats keep first-party calls separate from third-party ones, so the usage numbers stay honest.
  • Stack. TypeScript/Node workers → SQLite (WAL) → Express + x402 API → MCP client, run on my own VPS.

$PWIRE mint: 2b2Tv315U1FUtYF9Y1H2b2qrCnL3tN5QPabScFPCw8vw · #AnsemHack · Risk information from public onchain data only, not investment advice. $PWIRE is a utility token for the hackathon.


Selected work

Polymarket arbitrage bot

Pair arbitrage on Polymarket's 5-minute crypto markets. Rust on the hot path, Python for research, an explicit order state machine. Cut identify-to-send latency from 500 ms to 130 ms by measuring first and moving regions.

TickerFront

High-quality investor-relations websites for small publicly traded companies, plus a scraper that finds the ones that need it. The site an investor lands on before reading the filing.

MyGrokFlow

GTM IAAS for a client that I built. Helps GTM Agencies and the GTM process become optimized from a cost reduction standpoint and increase scalability.

BDRclaw

An AI BDR: prospect research, outreach drafts behind a human approval gate, reply classification, meeting booking and CRM sync across email, SMS and LinkedIn. Built to show safe agent design where AI touches customers. Walkthrough on request.

josephdev.online

My site in four languages (EN / ES / PT / IT): an About page with the 90-second intro video, and a resume you request through a form that routes straight to my inbox.


How I work

  • Scope and price in writing before a line of code. The customer approves the brief; I send progress reports while I build.
  • Keep the model out of the hot path. Deterministic code makes the decisions that move money or touch customers; the LLM researches, drafts and reviews.
  • Harness before horsepower. Evals, quality gates, spend caps, kill switches and a human approval step before any risky action.
  • Hand over, don't hold hostage. Docs, runbooks and a team that can run it without me. Ship something an account team can defend in a QBR, not a demo that dies after the call.

Background

Global consulting firm (client operations) → Sales Engineer, B2B SaaS → Account Manager, B2B SaaS → independent Forward Deployed Engineer shipping AI systems for operators and my own companies. About six years in total, all remote.

That path means I can own account health, renewals and escalations, run discovery and technical demos, and then build the thing myself.
