> Senior engineer at Quicknode building blockchain RPC and developer tooling used across the crypto ecosystem. I like things that are fast, small, and a little weird — x402 payment rails, agent arenas, raw-transaction sleuthing, healthcare dashboards that have to clear HIPAA. AI is changing development daily; the work now is finding the safe new tools that level up the LLMs. A lot was possible before; anything is possible now. If you're not using this day-to-day, you're falling behind.

▸
x402-rails
—Public package · payment rails for the agentic era
[2026]
Open-source backbone infrastructure for x402 — programmatic HTTP 402 settlements between AI agents and the services they call. Per-request stablecoin payments without an account, an invoice, or a tab. Free for anyone to drop in.
TypeScriptViemSolidityNode.js
▸
x402-payments
—Public package · drop-in x402 for any API
[2026]
Open-source SDK that lets a Node or Next.js endpoint quote a price, settle it on-chain, and serve the response — turning any function into an instantly-monetizable agent service. Install, wrap your handler, ship.
TypeScriptNext.jsViemEVM
▸
x402playground.com
—A live x402 sandbox
[2026]
Open the page, connect a wallet, watch real x402 calls execute against demo endpoints. The fastest way to see paid HTTP feel like a normal fetch().
Next.jsViemWagmiTailwind
▸
agentarena.xyz
—Where agents fight for benchmarks
[2026]
A leaderboard + match runner for autonomous agents — pit different models on the same task, score speed/cost/correctness, share replays. Every invocation is metered through x402.
Next.jsTypeScriptPostgresx402
▸
x402pokemon
—Pokémon trades over x402
[2026]
A demo that lets two agents trade Pokémon between each other with x402 settlements between every move. Pure showcase — also genuinely fun.
TypeScriptViemOpenAIx402
▸
wacdonalds
—AI burger ops
[2026]
A weekend project where an LLM runs the kitchen — orders flow in, agents fill them, x402 invoices print for every nugget. Half satire, half genuine experiment in agentic dispatch.
Next.jsTypeScriptOpenAIx402
▸
packz
—Bundles for autonomous agents
[2026]
Curated packs of x402-paid services an agent can subscribe to with one signature — research, code execution, rendering, image gen. Buy a pack, give it to an agent, watch it work.
TypeScriptViemNext.js
▸
story-block
—On-chain interactive fiction
[2026]
Branching narratives where readers vote on the next chapter with on-chain signals; outcomes get attested as blocks. Blockchain as story-state machine, not as ticker.
Next.jsSolidityViemMDX
▸
modtech
—Modular tech consulting
[2026]
Sticking-point code review + architecture work for early-stage teams. Drop in for a sprint, leave behind something that's still maintainable a year later.
TypeScriptNext.jsPostgresAWS
▸
enterprise cms dashboards
—HIPAA-compliant control surfaces
[2026]
Multi-tenant content + analytics dashboards built to clear HIPAA, SOC 2, and the audit trail every healthcare buyer asks for. Row-level security in Postgres, signed-URL document delivery, full event log.
Next.jsPostgres (RLS)TypeScriptAWS
▸
poc-distribution
—Referral fee distribution PoCs
[2026]
Three parallel proofs-of-concept for scalable on-chain referral payouts: 1inch CumulativeMerkleDrop, Thirdweb Airdrop, and Splits Protocol. Live-tested on Polygon mainnet with gas benchmarks.
TypeScriptSolidityViemHardhatPolygon
▸
rawtxnaddressfinder
—Raw transaction archaeology
[2025]
JavaScript CLI that decodes raw Ethereum transactions and surfaces the signer address + nonce without needing an RPC. Great for forensics and cold-wallet recovery flows.
JavaScriptethers.jsNode.js
▸
zlerplabs.com
—A personal sandbox
[2025]
Long-running experiments blog — part playground, part portfolio, part accidental README. Runs on Next.js with a custom MDX pipeline and view-transitions-powered post navigation.
