Development services

If it does not exist, we build it

The person who designs it writes the code, and the person who builds it runs it. Hands do not change midway.

Public · finance · defense systems

Designed to the standards of demanding sectors. From requirements and architecture to build, acceptance and audit documents.

JavaSpringeGovFramePostgreSQLOracle

Web & app services

Turn an idea into a running service. User screens and the operator console together, deployed to production.

ReactNext.jsREST API

AI agent development environments

Agents wired to your tools and data with Claude and MCP. Designed around the people who use them, so the team actually works with them.

Modernization & integration

Fix the system you run without stopping it. New features attach through APIs; data moves intact.

API integrationData migration

Cloud migration & automation

Move to AWS and Docker, with deployment automation and monitoring. When something breaks, the alert arrives first.

Operations & maintenance

The builders run it. Incidents and feature requests come through one channel to the same team, on monthly or yearly contracts.

Our solutions

Plug in and it runs

Three building blocks we built and use ourselves. They attach to a running service through API and SDK, without downtime.

Add-Chat

Real-time chat

Do not build chat yourself. Real-time 1:1 and group chat plus an operator console, attached in a few lines of code. It keeps working as users grow.

  • Every device, HTML5 and JSON standards
  • File transfer · read receipts · threaded replies
  • Statistics dashboard and admin console included
More about Add-Chat

Add-Push

Push messaging

Stop pulling developers in to send a push. Your staff pick the audience, schedule the send and read the results themselves.

  • Image and video push, guest delivery
  • Segments · schedules · A/B tests
  • Delivery logs and usage analytics in real time
More about Add-Push

Add-Flow

Logistics TMS / OMS

Stop reconciling orders, dispatch and delivery in spreadsheets. See the whole flow from order intake to delivery and settlement, tuned to your site rules.

  • OMS — intake · stock allocation · shipping · returns
  • TMS — route planning · dispatch · live tracking · POD
  • Standardized booking, dispatch and settlement

How we work

How a small team owns it end to end

Instead of adding people the way large vendors do, we cut the work with design and automation.

Design comes first

Documents before code. We write the screen list and data flow, then build.

Working screens every two weeks

You check real running screens, not documents. If the direction is off, we fix it at that step.

Common solutions over clever ones

Standards and conventions over tricks, so another developer can read it six months later.

The builders run it

We do not stop at handover. After launch the same team takes incidents and improvements.

Agents do the agent work

Repetitive work goes to Claude and MCP agents; people are kept for judgment. Our own development environment works this way.

Scope is fixed in writing

What is in and what is out is written before the quote. Out-of-scope requests are quoted for the next phase.

Process

From first contact to operations

Six steps. At the end of each one we decide together whether to move on.

  1. 01

    Consultation

    Post on the board or email us. A person replies. It is free.

  2. 02

    Scope & quote

    What is in and what is out, in writing, then a quote.

  3. 03

    Design

    Screen list, data structure and architecture fixed first.

  4. 04

    Build & demo

    Built in two-week increments, verified on working screens.

  5. 05

    Acceptance & launch

    Tested together, deployed to production, with operations docs.

  6. 06

    Operations

    A stabilization period, then monthly or yearly maintenance.

Before quoting we write the screen list and data flow together. Solutions and system builds alike are quoted after scope is fixed, and consultation and quotes are free.

FAQ

Before you hand it over

Can I ask before the plan is ready?

Yes. We define scope together.

If you can say who it is for and what it should do, that is enough. We lay out screens and data flow first.

Does it integrate with what we already run?

We attach without stopping your service.

You get API documentation and template code. Solutions plug in; modernization keeps your data in place.

Will it hold up as users grow?

Designed on MSA so it scales with you.

Event-driven architecture handles heavy traffic without lag.

Resources scale automatically under load (Auto-Scale).

Faults are detected and recovered automatically (Self-Healing).

How much is it?

There is no fixed price table. We quote after the scope is written.

Integration scope — which service, screens and data it attaches to

User scale — concurrent users and monthly active users

Customization — how much screens, rules and permissions are fitted

Operations — whether we run it after launch (monthly or yearly contract)

What about security?

One-way hashing for personal data, TLS for transport.

SHA-256 one-way hashing protects personal data; end-to-end TLS protects transport. Rate limiting blocks abnormal calls.

What do I keep when it is done?

A state another developer can take over.

Source code and design documents

An operator console and an operations guide

Code written the common way, easy to hand over
