Services

Software engineering services for businesses.

We design, build, integrate and operate web and mobile applications, backend systems and infrastructure — and add automation and AI where it measurably helps.

What we build

Six areas of work, often combined in a single project: a customer-facing product, the backend and infrastructure behind it, and the integrations, automation and AI features that make it useful day to day.

01

Websites & Web Apps

Company and product websites, customer portals and internal tools. Fast, accessible front ends backed by the server-side logic the product actually needs.

  • Company, product and landing websites
  • Customer portals and dashboards
  • Admin panels and internal tools
  • Static-first or server-rendered, as the use case requires

02

Mini Apps

Mobile-first experiences that run inside platforms such as Zalo, where customers already spend their time — without asking them to install another app.

  • Zalo Mini App development
  • Mobile-first UI and product catalog
  • Cart, checkout flow and payment integration
  • Customer accounts and back-end integration

03

Commerce & Business Systems

Online ordering and the operational tooling around it, designed to work alongside the systems a business already runs.

  • E-commerce storefronts and ordering flows
  • Order, catalog and inventory management
  • POS integration and stock synchronisation
  • Admin tooling and operational reporting

04

Backend, Cloud & Infrastructure

The services, data and hosting behind a product — designed to be deployed reproducibly, observed in production and operated after launch.

  • Backend services and REST APIs
  • Databases and data models
  • Cloud and self-hosted deployment
  • Monitoring, logging and ongoing operation

05

API Integration & Automation

Connecting existing software and removing manual steps between systems, so data stays consistent without staff copying it by hand.

  • Webhooks and third-party platform APIs
  • Payment gateway and POS connectors
  • Workflow automation and scheduled jobs
  • Data synchronisation and reconciliation

06

AI & LLM Integration

Claude integrations, RAG, AI assistants, workflow automation, tool use, and business knowledge systems — applied where they measurably help a workflow.

  • Claude API integration and conversational assistants
  • Retrieval-augmented generation over business knowledge
  • Tool use and agent workflows connected to business systems
  • Evaluation, observability and cost control

AI & Claude

AI & Claude

We are integrating Claude into AI-enabled applications and client solutions, including conversational assistants, retrieval-augmented generation, knowledge systems, workflow automation, and tool-based agent workflows.

Our focus is on practical production use: reliable API integration, structured tool use, secure access to business data, evaluation, observability, and cost-efficient deployment.

  • Conversational assistants

    Customer- and staff-facing assistants grounded in the business’s own information.

  • Retrieval & knowledge systems

    Retrieval-augmented generation over documents, catalogs and internal knowledge.

  • Tool use & agent workflows

    Structured tool calls that let a model read from and act on business systems within defined limits.

  • Workflow automation

    Language models inside well-bounded workflow steps such as drafting, classification and triage.

  • Secure data access

    Scoped access to business data, with credentials and permissions kept outside the model.

  • Evaluation & operations

    Test sets, logging and cost monitoring, so behaviour and spend are visible in production.
