The business operates on a one-person company (OPC) model, meaning the person who discusses requirements is also the one who writes the code. This structure eliminates sales layers and project manager markups, ensuring the requirements do not change and responsibility remains clear. The website states that the price is public, with starting costs listed directly on the site without requiring a phone call to get a quote.

The delivery pipeline consists of five steps: requirement evaluation and solution (1-2 weeks), prototype and UI design (1-2 weeks), feature development (3-8 weeks), testing and launch delivery (1-2 weeks), and after-sales maintenance. The company promises a 1-3-7 delivery commitment, which includes 3 free modifications and a 7-day period where unsatisfied work can be redone.

Pricing is handled through milestone-based installment payments, and the company offers a 3-month free maintenance period after launch. Small changes that can be done conveniently are not billed separately. The website explicitly states that source code, deployment scripts, and documentation are fully delivered to the client.

The business is located in Chengdu and operates nationwide via remote work. It has 12 years of full-stack development experience and has delivered over 80 projects across six technical directions. The team has 5 years of foreign enterprise remote development experience, having served exchanges and foreign exchange financial companies.

Clients can get started by filling out a requirement form or scanning a QR code to add the WeChat account shiyanfeng446. The company typically responds within 1-2 working days and offers a free feasibility assessment and rough cycle estimate before charging.

The business specializes in six main development categories: AI development, system development, APP development, mini-program development, custom development, and blockchain development. Each category includes specific sub-directions such as private RAG knowledge bases, CRM systems, iOS/Android apps, and smart contract security audits.

A representative case mentioned is a private AI knowledge assistant that reduced parameter lookup time from 40 minutes to 10 seconds by parsing 8,000 scattered manuals into an internal network query system with source citations. Another example is a customer CRM system that made overdue payments visible and prevented client loss when a salesperson left.

The business provides industrial OPC gateway services, including PLC data collection, multi-protocol conversion, and integration with MES/SCADA systems. They also offer custom agent and document parsing for internal Q&A robots in the AI sector.

The business targets clients needing full-stack software customization, from enterprise websites to Web3 DApps. It suits those who want a direct developer without sales layers, and those looking for private deployment or integration of legacy systems.
