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.
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.
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.
An Atyantik software engineering engagement runs in five phases: discover, specify, architect, build and hand over. Each one ends in a document you keep.
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.
Requirements go into a specification set you sign, so what counts as finished is agreed in writing before any code is written.
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.
Delivery runs in short increments against the signed specification, each one reviewed, tested and deployed through a pipeline that you can watch.
You receive the running system, its tests, its pipeline and a runbook, so your own team can operate it without calling us first.
Five documents, each settling a different question. We write the ones your project needs and say plainly which ones it does not.
| 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. |
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.
Send what you are building and a software engineer replies within one business day with the stages we would run.
Measured from engagement start date, client register.
Counted from enterprise engagements across 7 countries, 2015 onward.
Counted from billing jurisdictions on active and closed engagements.
The evidence
Three engagements, each anonymized to a class descriptor, with numbers published on its page.
We built a cloud-based RFID solution to help SMBs track inventory across multiple stores with real-time scan accuracy, automated vendor reordering, and smart SKU validation.
Designed for scale and built for non-tech teams.
We transformed a lagging frontend into a high-performance shopping experience with SSR, state management, and memory-optimized rendering.
Faster carts, smoother mobile, and onboarding across 4 cities.
We implemented an SSO architecture using Keycloak, bringing OAuth 2.0, user federation, and centralized authentication to a fragmented app ecosystem.
From fragmented logins to unified access.
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, 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.
Three engagements is what fits on a page. The rest of the anonymized case work is written up the same way, numbers and all.
See the anonymized case workWhere 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.
Your product already works and the real problem is that it falls over under load.
You want the whole catalogue of engagements in front of you before you choose one.
The answers you and the person signing the contract both want before anything starts.
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.
A software engineer replies within one business day.
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.
