Software Engineering That Outlives The Team That Built It

We write down why your system is shaped the way it is and hand it to you. Our longest active engagement is still running after more than a decade.

Your engagement, scoped before you commit

A senior software engineer reads it and replies within one business day with how we would scope it. No sales sequence.

Platforms rarely break at launch; they break in the year the last software engineer who knew why it was built that way leaves.

How we know

Drawn from delivery and maintenance work across 50+ enterprise engagements in 7 countries since 2015, and one engagement still running after more than a decade.

What happens when the people who built it leave

The code is still there. What is gone is the reasoning that made it that shape, and it left in somebody's head.

The one who knew why has gone.

Nobody left can say what the tradeoff was, so nobody will touch it.

The docs describe what, never why.

You can read every endpoint and still not know what was rejected.

A small change now takes a quarter.

Each estimate carries a fear tax nobody can price for you.

None of that is answerable from the code alone, because the code never recorded what it was chosen over.

What the first weeks actually do

An Atyantik software engineering engagement runs in five phases: discover, specify, architect, build and hand over. Each one ends in a document you keep.

Discover
We read the system you already have and interview the people who depend on it, then write down what we found and what we still cannot establish.
Specify
Requirements go into a specification set you sign, so what counts as finished is agreed in writing before any code is written.
Architect
We choose the architecture, record the alternatives we rejected and why we rejected them, and hand you that record instead of keeping it in our heads.
Build
Delivery runs in short increments against the signed specification, each one reviewed, tested and deployed through a pipeline that you can watch.
Hand over
You receive the running system, its tests, its pipeline and a runbook, so your own team can operate it without calling us first.

How deep the specification actually goes

Five documents, each settling a different question. We write the ones your project needs and say plainly which ones it does not.

The specification documents, what each settles, who signs, and what its absence costs
Document	What it settlesThe question it answers	Who reads itWhose sign-off it needs	What its absence costsWhat goes wrong without it
BRDBusiness requirements document	What it settlesWhy the project exists at all, and which business outcome counts as it having worked.	Who reads itThe sponsor funding it, and the executive who will be asked later whether it paid off.	What its absence costsScope arguments have no referee, so the loudest stakeholder wins each one in turn.
FRDFunctional requirements document	What it settlesWhat the system does, function by function, in language a non-technical reader can check.	Who reads itProduct owners, plus the client-side reviewer who signs each function off by name.	What its absence costsEvery ambiguity gets resolved by a software engineer guessing, and the guess ships.
PRDProduct requirements document	What it settlesWhat the product has to be for the people using it, and which behaviours are not negotiable.	Who reads itProduct and design, together with whoever will support the thing after launch.	What its absence costsDesign and delivery optimise for different products and only discover it at QA.
SRSSoftware requirements specification	What it settlesThe system requirements in testable form: inputs, outputs, states, limits and error paths.	Who reads itThe software engineers building it and the testers who have to prove it works.	What its absence costsThere is nothing to test against, so finished becomes a matter of opinion.
TRSTechnical requirements specification	What it settlesThe architecture, the stack, the interfaces and the non-functional limits it runs inside.	Who reads itThe software engineers who maintain it after we leave, and your own platform team.	What its absence costsThe reasoning stays in somebody's head, and it leaves the day they do.

What you receive, stage by stage

01
Discovery
We read the system you already have and interview the people who depend on it, then report what we found.
You receive
A findings note listing what exists, what is at risk, and what we could not establish.
02
Specification
Every requirement is written down in testable form and signed off by you before delivery starts.
You receive
The signed specification set: BRD, FRD, PRD, SRS and TRS, all yours to keep.
03
Delivery
Software is built in reviewed increments against that specification, tested and deployed through a pipeline you can watch.
You receive
Working software in your own repository, with its test suite and its CI pipeline.
04
Handover
We write down how to operate it, then prove your team can run it without us in the room.
You receive
A runbook and the architecture decision record, both of them yours to keep.

One sign-in for every application, with Keycloak SSO

We put Keycloak in front of a suite of separate web applications, moved their users into one store and gave every user a single sign-on, with OAuth 2.0, OpenID Connect and multi-factor authentication.

Several application logins became one sign-on, and authentication support tickets fell 70%.

View Case Study

Software engineering here is the whole arc, and several parts of it have a deeper engagement of their own: discovery workshops, prototyping, MVP development, SaaS product development, system integrations, RFID software for tags, readers and printers, infrastructure and DevOps, performance optimization, and ongoing support once it is live. Larger programmes usually start at enterprise-grade delivery, and the full service catalogue lists the rest. We work primarily in TypeScript and JavaScript across the browser, Node and the edge, and the stack we build on is published in full. For a company in New York, the page on custom software development for New York companies sets out working hours, code ownership and the record a vendor review asks for, before anything is agreed.

Three engagements is what fits on a page. The rest of the anonymized case work is written up the same way, numbers and all.

Whether this engagement fits

Where we fit

You are building or rebuilding something that still has to be maintainable in five years.
Somebody who understood your architecture has already left, or is about to.
You would rather have the reasoning written down than take it on trust from whoever is in the room.

Where we are the wrong call

You need a market-ready first version in weeks and can accept documenting less of it.
MVP development
Your product already works and the real problem is that it falls over under load.
Scale & Optimize
You want the whole catalogue of engagements in front of you before you choose one.
every service we offer

Questions before you commit

The answers you and the person signing the contract both want before anything starts.

How is this different from hiring contractors?

Contractors deliver code and leave. We deliver the code and the reasoning behind it: a signed specification set, a record of the architecture decisions and the alternatives we rejected, and a runbook. If we stopped tomorrow, your team would pick it up from documents rather than from an archaeology exercise.

What to verify in a software company's first month

Do we get the documents, or only the software?

Both, and the documents are yours from the day they are signed. They live in your repository alongside the code, not in a portal we control, so nothing you paid for is behind a login we own.

Which technologies do you build on?

We work primarily in TypeScript and JavaScript across the browser, Node and the edge. The full stack we build on is published, and we pick from it against your constraints rather than against our preferences.

How long does an engagement take?

That depends on what has to keep working, and we will not quote a duration before reading the system. What we can say up front is the shape: discovery and specification come first, and delivery starts once you have signed what finished means.

The five things that stretch a software delivery timeline

What happens when our requirements change halfway through?

They usually do. The specification set is versioned, so a change becomes a visible amendment with its own sign-off, rather than a quiet argument months later about what was originally meant.

Do we talk to a software engineer, or is this a sales call?

A software engineer, not a salesperson, replies within one business day. You describe what you are building and you get a technical answer about your system rather than a pitch.

Still deciding whether the paperwork is worth paying for?

Describe what you are building and a software engineer will tell you honestly which of these stages your project needs and which it does not.

Tell us what has to keep working

Describe what you are building and what it has to survive. A software engineer, not a salesperson, replies within one business day with how we would scope it.

You have seen the phases, how deep the specification goes, and exactly which documents you would receive from each stage. The next step is that shape applied to your own system rather than to a generic engagement.

Tell us what you are building and what has to keep working after handover, and a software engineer reads it and replies.
