What we do

Three things we do best

We're a software engineering partner for small and mid-sized businesses. Most work falls into one of these — and they often combine on a single project.

Custom software & modernization

Software built around how your business actually works

We design, build and modernize web and business applications for teams that have outgrown spreadsheets, off-the-shelf tools, or an ageing legacy system.

Integrations & AI automation

Connect your tools and automate the manual work between them

We connect the systems you already use — CRMs, accounting, payments, support, internal apps — and automate the repetitive work between them, including AI-assisted automation for tasks like document handling, triage and drafting.

Dedicated engineering teams

Senior engineers who work as an extension of your team

When you need engineering capacity without a long hiring cycle, we provide dedicated engineers who integrate with your tools, standups and workflow — and ramp up or down as your needs change.

How we work

From first enquiry to a working system

A straightforward process designed so you can judge fit early and never commit blind.

  1. 01

    You send an enquiry

    Tell us what you're trying to build or fix. A senior engineer reads it — not a sales rep.

    Discovery call

    A short call to understand your goals, constraints and what success looks like.

  3. 03

    Written scope & estimate

    You get a clear first milestone, approach and estimate before committing to anything larger.

  4. 04

    Build in iterations

    We work in short cycles with working software you can review, and regular demos.

  5. 05

    Launch & handover

    We deploy to infrastructure you control and hand over code, documentation and knowledge.

What you receive

  • Full source code and IP ownership
  • Deployment to your own cloud account
  • Automated tests and a deployment pipeline
  • Documentation your team can operate from
  • Direct access to the engineers doing the work

Why ARSTEG

Specific reasons teams choose us

Not “we're innovative and excellent.” Here's what's actually different about working with us.

Senior engineers do the work

You work directly with experienced engineers, not a layer of account managers passing messages to a junior team.

We scope before we quote

Engagements start with discovery or a small milestone, so you get a written plan and estimate before any big commitment.

Modernize without the risk

We replace legacy systems incrementally and build alongside what you have — no big-bang rewrites that stall your operations.

We fit your existing tools

Integrations and automation that connect the systems you already run, rather than forcing you onto something new.

Clear, direct communication

Regular demos, honest status, and a straight answer when something is harder or simpler than expected.

You own everything

Full source code and IP, deployed to infrastructure you control. NDA available on request.

Questions buyers ask us

Straight answers to help you decide if we're a fit.

We focus on small and mid-sized businesses across India, the US, UK and Europe. Typical projects range from roughly $10,000 to $75,000, plus ongoing monthly engagements for dedicated teams.
