01What I build

Tokenta — a verifiable exchange for AI capacity, settled on-chain.

A trust layer for AI assets — verification, escrow, reputation and low-latency execution. I designed and built the backend from scratch.

  • 0.8ms median match latency across 12 regions
  • $200M+ notional reconciled through multi-sig escrow
  • 6-stage verification pipeline emitting signed evidence

02Capabilities

Three systems I've built end-to-end.

Each one ships in production at Tokenta and maps directly to the line items in Web3 backend job descriptions.

Matching engine01

Sub-millisecond matching path

Lock-free order book with price-time priority and idempotent fill settlement. 0.8ms median match latency across 12 regions, written in Rust and Go.

RustGolock-freeprice-timeTCP
On-chain escrow02

Multi-sig settlement & indexing

Solidity escrow with deterministic release conditions and an attestor quorum, plus a reorg-safe indexer and settlement service reconciling $200M+ in locked notional.

SolidityFoundrymulti-sigreorg-safeindexer
submithashauditprobequorumlisting
Verification pipeline03

Six-stage attestation

Provenance hashing, static audit, behavioural probing and a multi-party attestor quorum. Modelled as an event-driven state machine emitting signed evidence bundles.

03Master's research, in a terminal

The dissertation, re-read as backend engineering.

A synchronous agent protocol, a sub-second hot decision path, and a reproducible, audited harness. Run the commands.

04From product to protocol

A six-year arc, ending on-chain.

Product manager → frontend → backend → Web3 backend. Each step compounded toward distributed, performance-critical systems.

  1. Tokenta

    Co-Founder & Backend Engineer

    web3current
    Tokenta· Remote
    Mar 2024 — Present

    Multi-chain AI-asset exchange — verifiable compute, API quotas and model-access rights.

    • Architected the entire backend from zero — service topology, data model and the on-chain/off-chain boundary.
    • Built a sub-millisecond matching path with a lock-free order book and idempotent fill settlement across 12 regions.
    • Designed multi-sig escrow (Solidity / Foundry) and a reorg-safe indexer / settlement service reconciling $200M+ notional.
    • Multi-chain RPC orchestration with dynamic node scaling and automatic fail-over; 99.998% terminal uptime.
  2. Goldsky

    Backend Engineer Intern (Web3)

    web3
    Goldsky· Remote · Brooklyn, NY
    Sep 2023 — Aug 2025

    On-chain data and indexing infrastructure used by subgraph and webhook customers.

    • Owned a multi-chain RPC scheduler, contract event listeners and an on-chain reconciliation service in Go.
    • Tuned a Kafka ingestion pipeline that absorbs chain-reorg and duplicate events idempotently.
    • Cut ingestion-to-query p99 by ~38% via streaming JSON-RPC decoding and off-path reorg detection.
  3. Reservoir Protocol

    Backend Engineer Intern (Web3)

    web3
    Reservoir Protocol· Remote · New York, NY
    Feb 2023 — Aug 2023

    NFT orderbook and aggregator infrastructure across EVM chains.

    • EIP-712 wallet-signature verification, dynamic gas estimation and aggregation-routing APIs in Node / TypeScript.
    • Integrated Ethereum, Polygon, Base and Arbitrum with fallback RPC providers and circuit-breakers.
    • Solidity adapters and forked-mainnet integration tests (Foundry) for order-cancellation and seaport-fill paths.
  4. Flipside Crypto

    Backend Engineer Intern (Web3)

    web3
    Flipside Crypto· Remote · Denver, CO
    Jul 2022 — Jan 2023

    On-chain analytics and quant data warehouse for analysts and external dashboards.

    • Block crawlers and transaction-parsing services (Python / Go) into a curated Snowflake / ClickHouse warehouse.
    • Idempotent backfill orchestrator with checkpointing and DLQs that absorbed RPC outages without manual replay.
  5. Mercury

    Backend Engineer Intern

    Mercury· Remote · San Francisco, CA
    Jun 2021 — Aug 2022

    Banking-for-startups — payment-ledger and reconciliation services.

    • Double-entry ledger with idempotency keys and exponential-backoff retries for ACH / wire reliability.
    • Improved API response time ~30% via tighter indexes and a batched loader replacing N+1 reads.
  6. Pave

    Frontend → Backend Intern

    Pave· Remote · San Francisco, CA
    Jun 2020 — May 2021

    Compensation-data SaaS (YC W19) — moved from the dashboard into platform.

    • React / TypeScript dashboard, then server-side: API gateway, JWT rotation, RBAC scopes, webhook-signing helper.
  7. Pry Financials

    Product Manager Intern

    Pry Financials· Remote · San Francisco, CA
    Jul 2019 — Apr 2020

    Financial-modelling SaaS (YC W20) — first role before transitioning to engineering.

    • PRDs, prototypes (Figma) and roadmaps for a runway-modelling product; user research with 20+ founders.
