Software development, modernization and AI automation for businesses in India, the UK and Europe.
Custom web platforms, integrations between the tools you already use, and upgrades to software that's holding you back. Designed, built and supported by one engineering team, from first call to production.
Organisations in India, the UK and Europe with software that already matters to the business.
Members, customers, stock or bookings tracked in Excel files and registers that nobody fully trusts.
How we replaced paper registersInvoices typed in twice, reports assembled by hand, the same customer in three systems.
How we'd connect themFigures from many branches or teams, each person seeing only their part, with exports that show where numbers came from.
Seven-level reporting we builtWhat working with a focused engineering team means for you.
No account managers or hand-offs. The engineers on your first call design, build and deploy your system.
We take on a small number of clients at a time, so your project is never one of fifty.
The platforms we build run in production on Azure, and we keep running them. We'll walk you through how they're built.
Begin with a written assessment or a single module. If it works, we carry on. If not, you haven't committed much.
Engineering from India at rates well below UK, European and US agencies, to the same production standards. Defined work gets a fixed price, so there are no surprises.
Working software in your hands within two weeks of starting, and a new increment every two weeks after that. No months of silence before a demo.
We review your existing software, data and process, and send back what we found: the risks, the options and what each would take. A clear starting point before you commit to a build.
Ask for an assessmentWhen someone you refer becomes a client, you both get 5 to 10% off.

Full-stack applications and enterprise platforms, designed, built and taken into production by the engineers who scoped them.

AI doesn't replace good engineering. It depends on it.
In CodeGate, hidden tests decide whether code works. AI only scores quality against a written rubric and summarises each answer for a reviewer.
Mandate, in development: an AI agent can act on ERP data only through approved actions, and risky ones wait for a person.
In our client platforms, recurring events and data-completeness checks run as scheduled background jobs. No AI required.
Where AI makes a judgement, the reasoning is shown and a person can override it.
Every system is designed as a whole, from the screen a user touches to the pipeline that releases it. These are the layers, and what we build them with.

Records, workflows, integrations and reporting, shaped around how your organisation actually works.
Member records, events, live check-in and statistics across a seven-level hierarchy, in production today.
See the workStock records, barcode capture, reorder rules and the reports your operations and finance teams need.
Invoices posted to Tally or Zoho Books, payment gateways, and reconciliation that runs on a schedule.
Appointments, reminders and records for clinics, studios and service businesses.
Courses, quizzes and certificates, and coding assessments: we built CodeGate for our own hiring.

Existing systems often contain years of business knowledge. We modernize intelligently instead of rewriting everything unnecessarily.
Architecture, development and delivery remain connected. The people who scope your system build it and support it.
We care about deployment, reliability, observability and real-world operation — not just prototypes.
We choose the architecture and stack for the problem in front of us, rather than forcing every project into the same solution.
What goes into the production systems we run, as standard.
Altherix was founded in Ooty, high in the Nilgiris, and works from Coonoor in Tamil Nadu, India. It's an unusual place for an engineering company, and a deliberate one: a small team with room to do careful work, away from the churn of a large delivery centre.
The work reaches well beyond the hills. Platforms we built run in production on Azure for The Church of Pentecost in the UK and its Missions Office in Ghana. We take on projects across India, the UK and Europe.
One conviction hasn't changed: your existing software is the backbone of your business, and it usually deserves improving before it deserves replacing.
Our CSR unit puts the skills we use every day to work for the community around us in the Nilgiris.
Free coding training for students from the Nilgiris, assessed on CodeGate. The strongest are offered a paid Altherix internship.
Each year we build or fix a system for a nonprofit, school or clinic, free of charge.
What happens after you get in touch, and what you get at each step.
Altherix is a small software engineering company. We build custom web applications and enterprise platforms, modernize existing systems, add automation and AI where it helps, and connect business systems to each other. We also deploy and run what we build.
You work directly with the engineers who design, build and run your system, with no account managers or hand-offs. Our platforms run in production on Azure for clients in the UK and Ghana, including a church management system with 80+ API modules and statistical reporting across seven organisational levels, and we'll walk you through how they're built.
Our production work is in .NET 9 and ASP.NET Core, React and TypeScript, Laravel and PHP, SQL Server and MySQL, on Azure with Azure DevOps pipelines. We choose the stack that suits your system rather than forcing one.
With a free 30-minute call with an engineer. We then review your existing system and send a written assessment with options, followed by a proposal: fixed scope and price for defined work, or a monthly team for ongoing work. Build work happens in two-week increments you can see and use.
Our rates are well below those of UK, European and US agencies, and defined work gets a fixed price agreed before we start. You'll have working software within two weeks of starting, followed by a new increment every two weeks.
Yes, and we recommend it. Start with a written assessment or a single module. If it works for you, we carry on; if not, you haven't committed to a large project.
Yes. If you refer a client to us, both you and the client you refer get a 5 to 10% discount.
Our office is in Coonoor, in the Nilgiris district of Tamil Nadu, India. Altherix was founded in nearby Ooty. We take on projects remotely across India, the UK and Europe.
Whether you're modernizing a legacy platform, integrating enterprise systems, or figuring out where AI actually fits, start with a conversation with our engineering team.
