Minner — Web3 Automation Developer

Minner

Web3 Automation Developer

Based in Shanghai · Available for remote Web3 work

About

Automation thinking, applied to Web3.

I'm Minner, a Web3 automation and backend developer based in Shanghai. Before moving deeper into Web3, I spent years building Python scraping, data automation, and backend systems. That background shaped how I work: I like finding hidden workflows, understanding edge cases, and turning messy manual processes into reliable tools.

Today I focus on Web3 automation, smart contract integrations, on-chain data tools, exchange API monitoring, Chrome extensions, and AI-assisted engineering workflows. My edge is combining automation thinking, data extraction, backend engineering, and Web3 execution into practical tools that help teams move faster.

Projects

Featured Projects

A few systems I have built or researched across Web3 automation, trading tools, smart contract workflows, and browser-based productivity.

Alpha-Trace Agent

On-chain Wallet Analysis · Web3 Agent

Problem

Web3 users and teams need a structured way to analyze wallet behavior and generate evidence-based risk reports.

Solution

An agent workflow that analyzes wallet activity, stores task data, and generates structured reports — connecting backend services, database storage, and smart-contract interactions.

Result

Testnet contract deployed and backend workflow implemented.

What this proves

I can connect on-chain data, backend workflows, database storage, and smart contracts into one working system.

What I can build for you

Wallet monitoring tools, on-chain analytics dashboards, address risk reports, Telegram alerts, and custom Web3 data workflows.

Exchange Spread Monitor

Exchange API · Spread Monitoring

Problem

Token pairs across exchanges may show small price differences, but it is hard to judge whether the opportunity is real after fees, depth, and execution risk.

Solution

A monitoring and simulation tool for pairs like USDT/USD — historical spread analysis, max/min profit simulation, fee modeling, and risk checks.

Result

Simulated spread opportunities and built a foundation for risk-controlled trading research.

What this proves

I can work with exchange APIs, trading data, fee models, simulations, and risk-aware automation.

What I can build for you

Exchange spread monitors, funding-rate dashboards, price alert bots, trading data pipelines, and Telegram notification systems.

Chrome Extension Workflow Tool

Chrome Extension · Automation

Problem

Many business workflows require repeated manual operations across web platforms — reading page data, extracting structured information, and triggering analysis.

Solution

Chrome extension tools that extract page data, automate repetitive workflows, and connect browser-side actions with backend services and AI analysis.

Result

Practical browser automation tools for real-world workflow improvement.

What this proves

I can build browser-side tools that connect user workflows, page data, backend services, and AI systems.

What I can build for you

Chrome extensions for Web3 dashboards, exchange workflows, wallet tagging, research tools, internal operation tools, and data extraction.

Why Work With Me

Built for practical, reliable delivery

I focus on practical delivery, clear communication, and building tools that actually fit your workflow.

01

End-to-end delivery

I can work across smart contracts, backend APIs, databases, automation scripts, and dashboards.

02

Fast prototypes

I can build a working MVP first, so you can test the core workflow before expanding the full system.

03

Clear written communication

I provide structured updates, explain trade-offs, and work well with async international teams.

04

Practical engineering

I focus on tools that solve real workflow problems, not over-engineered demos.

05

Security awareness

For Web3 projects, I use isolated environments, review dependencies, and avoid unsafe handling of private keys or sensitive credentials.

Process

From workflow to working tool, in four steps

A simple collaboration process designed for fast validation and reliable delivery.

01

Understand the Workflow

I learn your current process, technical stack, pain points, and the result you expect.

02

Design a Practical Solution

I break the requirement into modules, APIs, data flow, contracts, automation tasks, or dashboards.

03

Build a Fast Prototype

I deliver a working MVP quickly, so you can test the core workflow early.

04

Improve and Deliver

I refine the system, fix edge cases, add documentation, and prepare it for real usage.
