Services & solutions

From a requirement to a system that runs

Our services are organised around business value rather than technology stacks. Each can be engaged on its own or combined into a complete programme.

01

Custom software development

Systems and applications designed around a specific workflow, replacing scattered spreadsheets, chat threads and manual handoffs.

When off-the-shelf software does not fit the process and people end up moving data between tools by hand, building is often the cheaper option. We start by mapping the existing process, design the data model and permission structure, and deliver a system your team is willing to use.

Typical stack

  • TypeScript
  • React / Next.js
  • Node.js
  • Java / Go
  • PostgreSQL / MySQL
  • WeChat mini program

What you get

  • Requirements documentation and feature list
  • Prototypes and interface design
  • Web / mini program / mobile applications
  • Admin console and role-based permissions
  • Integration with third-party systems
  • Source code, deployment docs and user guide

02

AI & data services

Large language models and data capability connected to real operations, producing measurable gains rather than a demo.

We help identify where AI actually pays off, then run the full path: data preparation, model integration, evaluation and production rollout. Alongside that we handle data governance and visualisation, so information scattered across systems becomes a dashboard you can decide from.

Typical stack

  • LLM APIs
  • RAG / vector search
  • Python
  • ETL & data warehouse
  • BI visualisation
  • Workflow orchestration

What you get

  • AI opportunity and feasibility assessment
  • LLM applications and intelligent support agents
  • RAG knowledge bases and document Q&A
  • Data collection, cleaning and governance
  • Operational dashboards and reporting
  • Workflow automation and agent orchestration

03

Internet products & technical services

Complete support for products from zero to one, plus engineering capacity when your team is stretched.

From product planning and interface design to deployment and long-term operations, we cover the product lifecycle. Teams that already have engineers can also buy our capacity by the day as an extension of their own.

Typical stack

  • Next.js
  • Tailwind CSS
  • Linux / Nginx
  • Docker
  • CI / CD
  • Cloud infrastructure

What you get

  • Product planning and scope definition
  • UI / UX design and design systems
  • Corporate sites, brand sites and SEO
  • Cloud server deployment and launch support
  • Monitoring, backup and performance tuning
  • Remote or on-site engineering outsourcing

How a project moves

Every stage has a concrete output, so you always know where the project stands.

  1. 1

    Discovery

    One session, online or in person, to understand the current process, the pain and the goal.

  2. 2

    Proposal & quote

    A feature list, technical approach, timeline and a firm quote — then we sign.

  3. 3

    Design & build

    Milestone-based delivery with working demos at every stage, so direction can be adjusted early.

  4. 4

    Launch & operate

    Deployment, handover of source code and docs, warranty-period maintenance and further iteration.
