Software & IT for growing businesses · Colombo, Sri Lanka

Ideas are easy.
Execution is engineering.

We build the software and systems businesses run on: websites, apps, business systems, networks and the infrastructure behind them. From the first conversation to long after launch.

$n exec ps --all01

Everything IT, under one roof.

Most businesses end up juggling a web person, a network person, and whoever set up the office printer. We do all of it, and we'll tell you plainly what you actually need.

Something else?

If it plugs in, runs on a screen or needs a network, ask us. We'll tell you honestly whether we're the right people for it.

$n exec run --phase all02

How working with us actually goes.

Four steps, and you'll know where things stand at every one. No jargon in the updates, no surprise invoices, no disappearing halfway through.

01

Understand

We sit down and work out what you actually need, which is often not what you first asked for. You get a written scope and a fixed price before anything starts.

  • What you need
  • Written scope
  • Fixed price
  • Timeline
02

Plan

We design how it will look and how it will work, and show you before we build. Changes are cheap at this stage and expensive later.

  • Designs to approve
  • How it works
  • Your data, safely
  • Sign-off
03

Build

We build it in stages you can see and try, not behind a curtain for three months. You get a progress update every week.

  • Working versions
  • Weekly updates
  • Properly tested
  • You try it
04

Launch & support

We put it live, train your team, and stay on to fix and improve. Your data stays yours and portable, so you are never trapped with us. You stay because it works.

  • Go live
  • Team training
  • Ongoing support
  • Your data, portable
WHAT YOU OWN

Two questions come up on almost every project: do I get the code, and can you sell my idea to someone else? Here are the straight answers, before you have to ask.

Yours
  • On a custom project: the full source code of your system, bar our internal build and deployment tooling. Keep it, change it, extend it, or hand it to another developer. It is yours to do whatever you want with.
  • On one of our products customised for you: a licence to use the platform, plus any modules we build specifically for your business. The platform source stays with us, so those modules aren't much use on their own. We tell you which of the two you are getting before you sign, never after.
  • Your data either way: sales, customers, stock and staff records, exportable any time.
  • Your branding, and your business rules like pricing and discount logic, supplier terms, commission structures and approval steps.
Ours
  • The right to reuse the code and components we wrote. Writing something once doesn't mean we forget how.
  • The platform, components and tooling we bring to every project, plus our internal build and deployment pipelines.
  • The freedom to keep working in your field, including on our own products. If another business asks us for something similar, we build theirs from our own tools, never from your system.
WHAT WE WON'T DO

Your finished system, your branding and your setup are not ours to pass on. We will never hand them to another client or resell them as they stand. Think of it like hiring an architect: the house is yours and the drawings are yours, but the architect doesn't forget how to design houses, and stays free to design another one down the road.

Everything above is non-exclusive, and your contract sets it out in full before any work starts.

$n exec ls ./work03

Work we've delivered, still running today.

A few of the projects we've built. Some clients asked us not to name them, so those appear unnamed, but the detail is real.

Property operations2025

TenantPay

LEX Engineering (Pvt) Ltd

Tenant billing and collections for Majestic City. Utility readings, rent cycles and shared-service charges were being reconciled by hand across a few hundred units, which meant invoices went out late and disputes were settled from memory.

Outcome
Billing cycle closes on schedule, with an auditable trail per unit

Building systems2025

BMS Reporter

LEX Engineering (Pvt) Ltd

Reporting layer over the building management system at Kelun Pharmaceuticals. A GMP site has to evidence its environmental conditions, and the BMS held the data but could not produce the record an auditor asks for.

Outcome
Scheduled compliance reports pulled straight from live plant data
Node·TimescaleDB·BACnet

Embedded & IoT2025

Lift Controller

CJ Holdings

Controller and monitoring stack for a lift installation. The constraint was the one that always applies to embedded work in a building: it has to fail safe, and it has to keep behaving when the network in the riser does not.

Outcome
Fault state and call history visible without a site visit
C·ESP32·MQTT
Read the case study
Retail systems2025

Point of Sale

CJ Holdings

Counter-side billing and stock control. Retail floors lose money the moment the till stops, so the till does not depend on the network being up — it queues locally and reconciles when the link returns.

Outcome
Sales keep running through connectivity drops

Web platform2025

Kandy Travels

Kandy Travels

Public site and enquiry pipeline for a tour operator. Enquiries were arriving across three channels and being answered from whichever one someone happened to check, so the work was as much about the intake as the pages.

Outcome
Every enquiry lands in one queue with a response clock on it

Learning platform2025

Success Online Institute

Success Online Institute

Course delivery and enrolment for an online training provider at et-gtec.com. Students, cohorts and payments each lived in a separate tool, and the reconciliation between them was a person.

Outcome
Enrolment through to completion tracked in one system

$n exec ls ./products04

Our own products, built in-house.

Alongside client work we build our own systems, so you start from something that already runs instead of a blank page. Each one is delivered as a project and fitted to how you work — not a subscription. These are early; we'll share more as each is ready.

You don't need to read this bit.

We pick tools to fit the job, not the other way around. But if you have an IT person who wants to know what we work with, this is for them.
