Senior Software Engineer (backend/systems), 5+ years production, with a track record spanning verifiable AI asset protocols, on-chain trust infrastructure, and high-stakes trading products. I design systems where proof comes before liquidity — combining systems-engineering rigor with hands-on full-stack delivery.

Previously WeBank (Federated Learning Intern, ML Platform & Explainable Risk Systems), Sony (AI Product Design), All Way Success (Senior PM on the AllWeb3 platform), and SUSTech (Research Assistant, Digital Twin Systems). Currently building Tokenta, a verifiable AI asset exchange.

Academic background in systems engineering, with 3 published papers and 2 patent applications in AI, digital twin, and ergonomic systems.

Small, honest, executable projects — full test suites, no inflated claims:

• campus-secondhand-marketplace — Spring Boot 3.2 + React 18 full-stack portfolio reconstruction (monorepo): JPA/Hibernate 6, Flyway, Testcontainers MySQL 8 integration tests, Axios 401 single-flight refresh. Actively built in the open, roadmap tracked as GitHub issues.
• rfc9421-signing-demo — Executable subset of RFC 9421 HTTP Message Signatures (ed25519 / hmac-sha256, RFC 9530 Content-Digest binding), with negative verification tests, typed error codes, real benchmarks, and an honest SECURITY.md.
• escrow-state-machine-ts — Rule-level reconstruction of an escrow settlement flow from a portfolio case study: state machine with golden fixtures, settlement reports, fund-flow conservation checks, and invariant tests.
• federated-learning-dp-sim — Horizontal federated learning with differential privacy in pure Python (FedAvg, update clipping + Gaussian noise, simplified privacy accounting) on synthetic risk data — an independent reproduction of FATE-style federated workflows, with a centralized/FedAvg/FedAvg+DP comparison experiment and 17 tests.
• predictive-maintenance-rul — Remaining-useful-life prediction mini-system for digital-twin predictive maintenance: synthetic run-to-failure generator, health index, degradation-model estimator, honestly benchmarked against a naive baseline (pooled RMSE 29.4 vs 39.9 cycles), 17 tests.
• dataquest-task-lifecycle — Reconstruction of a task-lifecycle state machine (13 states, 19 transitions, incl. abandonment/expiration/dispute/resubmit) from a case study: Mermaid diagram generation, SLA deadlines, and a runnable CLI demo.

Institutional-grade terminal for trading, verifying, and escrowing AI compute capacity and API access rights. Core thesis: Proof Before Liquidity.

A full-stack protocol platform where AI quotas and API access rights are verified, tokenized, and traded through non-custodial smart escrow. Every asset must pass a multi-step verification pipeline before it can be listed. On-chain reputation anchors each participant's history to their wallet identity.

Architecture:

• Verification Pipeline: automated endpoint testing, quota validation, proof-hash minting
• Smart Escrow Contracts: non-custodial, condition-based fund release with dispute resolution
• On-Chain Reputation: SBT-anchored trust scores, staking collateral, slashing mechanics
• Tokenta Terminal UI: Bloomberg-inspired monochrome interface, buyer/seller mode toggle, live escrow panel

Whitepaper available on request.

A multi-portal platform solving the transparency and KOL accountability crisis in Web3 marketing and PR.

Built the complete frontend architecture and product specification for a platform that aggregates on-chain KOL behavior, computes multi-dimensional trust scores, and provides project teams with verifiable marketing intelligence.

Key Modules:

• Trust Verification Center: multi-factor KOL wallet analysis, risk scoring, evidence chains
• Blockchain Tracker: interactive timeline of on-chain KOL activity across multiple chains
• KOL Assessment Center: ranked pool with verified badges, investment performance data
• Strategy Builder: smart-contract milestone tools, budget allocation, performance dashboards
• Transparency Monitor: real-time project transparency scoring, on-chain data integrity tracking

Technical SEO uplift from 38% to 83% site health through structured implementation.

Product architecture for a trust-minimized PR collaboration and effect verification system on-chain.

Designed the complete product model for a three-portal Web3 platform with smart contract escrow integration, oracle-based verification, and blockchain transaction management across Creator Portal, Project Portal, and Admin Portal.

Deliverables produced:

• Full PRD with 500+ Linear task items across 12 workstreams
• Smart contract escrow staking and phased settlement mechanism specifications
• Multi-KOL attribution and incentive distribution modeling (with numerical simulation)
• Database schema design (DrawSQL): users, wallets, campaigns, on-chain transactions, deliverables, KPIs
• Custom admin authentication architecture separate from Privy wallet-based portal auth
• NestJS + PostgreSQL + Prisma + Swagger + Docker + GitHub Actions backend specifications

Open-source event landing page template with real-time 3D lanyard physics, personalized badge generation, and shareable encrypted URLs.

Built as a production-grade template for global Web3 developer events. Features a fully interactive 3D lanyard with real-time physics simulation, a personalized badge generator with dark/light variants, PNG export, and dynamic Open Graph image generation for social sharing.

Stack: Next.js · React Three Fiber · Rapier Physics · TypeScript · TailwindCSS · WebGL · Canvas API

Features:

• Physics-simulated 3D lanyard with real-time interaction
• Canvas-based badge texture rendering with user name input
• Encrypted shareable URLs with per-user lanyard state
• Dynamic OG image generation via Edge API routes
• Dithered animated background, decrypted text reveal animations

Led 0-to-1 product build and two fast iterations for a proof-of-reputation-based marketing platform.

Outcomes:

• Scaled early user base from 500 to 15,000 in two weeks via referral quest design
• Top campaign exceeded 1 million views
• IA and onboarding redesign delivered +30% retention and conversion uplift
• Designed Sybil-resistant reward mechanics, dispute resolution flows, and slashing rules
