Some projects are under NDA — we show them on a call, with the client’s permission.

01 Problems

Sound familiar?

These are the situations people come to us with. Different tasks, one mechanic: we describe the process, automate the bottleneck and hand it over working.

  • “Requests come into chats and get lost, we count everything in Excel.”

    Intake with validation, a record in the CRM and a notification to the person responsible.

  • “Payouts and reconciliation are done by hand — and there are mistakes.”

    A settlement module with rules, an operation log and export to your accounting.

  • “Staff repeat the same action a hundred times a day.”

    An internal tool built around the actual process, not around a generic CRM.

  • “We have the data but no reporting.”

    A dashboard and scheduled reports that land where the team already works.

  • “Under peak load the service falls over and we hear about it from clients.”

    Profiling, queues, caching and idempotency — plus monitoring with alerts before users notice.

  • “There is a system, but every change means two weeks and a new invoice.”

    An audit, documentation and a handover so the code stops being a hostage situation.

Your situation is not on the list? Describe it — we will say honestly whether we take it

02 Services

What we build

Four directions on one backend contour. One contractor for the whole chain — bot, payments, admin panel, dashboards — instead of stitching three teams together.

01 / 04

01

Process automation

A repeated action leaves the working day and becomes a service that runs itself.

Typical tasks

  • Request intake with validation and routing to the person responsible
  • Telegram bots for sales, support and internal operations
  • Scheduled jobs, notifications and background workers
  • Data sync between CRM, spreadsheets and your systems
Stack Python · aiogram · Celery · Redis · PostgreSQL
Typical duration: from 2–4 weeks Estimate this task
02

Internal systems and admin panels

Software shaped around your process, instead of your process bent around generic software.

Typical tasks

  • Client portals and back-office panels with roles and permissions
  • Dashboards, scheduled reports and exports
  • Audit log: who changed what and when
  • Migration off spreadsheets without losing history
Stack FastAPI · Django · React · Astro · PostgreSQL
Typical duration: from 4–8 weeks Estimate this task
03

High-load services

The service survives the peak, and you hear about problems from monitoring rather than from clients.

Typical tasks

  • Profiling and finding the real bottleneck before rewriting anything
  • Queues, caching, read replicas, horizontal scaling
  • Idempotency and retries so nothing is processed twice
  • Monitoring, alerts and load testing before release
Stack PostgreSQL · Redis · RabbitMQ · Docker · Grafana
Typical duration: audit from 1 week Estimate this task
04

Integrations and payments

Money is counted by the system, with a log — not by a person in a spreadsheet.

Typical tasks

  • Payment providers and acquiring with reliable webhook handling
  • Reconciliation, settlements and payouts by rules
  • Integration with accounting, CRM and external APIs
  • Access control and an operation history that survives an audit
Stack Stripe · acquiring APIs · webhooks · PostgreSQL
Typical duration: from 3–6 weeks Estimate this task

A task that sits between these, or is not on the list at all? Describe it — we will tell you honestly whether we take it, and if not, who does it better.

03 Process

How the work goes

Every step has a deadline and an artefact you keep — not a verb. This is what replaces promises about quality.

  1. 01

    Call, 30 minutes

    We ask about the process, the constraints and what is already in place.

    You get
    An honest answer on whether we take it, and a rough shape of the solution
    From you
    A description of the task in your own words
  2. 02

    Scope and estimate, 2–3 business days

    We break the task into work items and price them with the risks named.

    You get
    Work breakdown, timeline, budget range, risk list — free, and yours to keep
    From you
    Access to the current system or a couple of clarifying answers
  3. 03

    Sprints of 1–2 weeks

    We build in short cycles and show working software, not screenshots.

    You get
    A demo every Friday, repository and staging access from day one
    From you
    1–2 hours a week for the demo and acceptance
  4. 04

    Launch

    We deploy to your infrastructure and hand over everything needed to run it.

    You get
    Production, accounts, deployment instructions, API docs
    From you
    Acceptance and the accounts the services will live on
  5. 05

    Support

    Defects on us, development by agreement.

    You get
    A warranty period, an agreed response time, monitoring and alerts
    From you
    A decision on the support format — or nothing at all

04 Formats

How you can work with us

When the task is broad, the format matters more than the price list. Pick the model that matches how well the scope is defined.

Fixed price per stage

What it is

Scope, price and deadline are locked before we start. Changes go into a separate stage.

Choose when

The task is described, this is our first project together, you need a predictable number.

Bad fit when

The product is still being figured out and the scope changes every week.

Sprints, time and materials

What it is

Two-week cycles, priorities re-agreed before each one. You can stop after any sprint.

Choose when

There is no spec yet, the direction is clear but the details are not.

Bad fit when

You need one invoice for the whole year — take the fixed price instead.

Dedicated developer

What it is

An engineer works inside your team, your process and your tracker. Billed monthly.

Choose when

You have your own tech lead or product owner and need hands.

Bad fit when

There is nobody on your side to set the tasks.

Support and development

What it is

A monthly fee with an agreed response time. Month to month, no annual lock-in.

Choose when

The system is live and needs someone responsible for it.

Bad fit when

You only need a one-off fix — that is a stage, not a subscription.

What drives the price
  • Number of roles and permission levels
  • Integrations with systems you already run
  • Load and reliability requirements
  • Data volume and migration from the current system
  • Urgency — a compressed deadline costs more than a normal one

For a first project we usually suggest a fixed price per stage: you risk one known amount rather than an open-ended estimate.

05 Risk

What we commit to

Not “quality and an individual approach” — obligations that go into the contract and can be checked against it.

01 / 07

06 Fit

Who we fit — and who we do not

We will work well together if

  • There is a person on your side who makes decisions
  • The task is about processes, money or load — this is where we are strongest
  • You are up for a weekly demo and acceptance
  • You need someone responsible for the whole loop, not a one-off patch

We are probably not the right fit if

  • The result is needed immediately and there is no time to work through the task
  • Work without a contract
  • We need to pick up someone else’s code with no access to the author and no chance to audit it first
  • Your current team already covers this — we will say so rather than take the work

Everything else is up for discussion. If the task is not ours, we say so on the first call and, where we can, point you to someone better suited.

07 Questions

Questions we get asked

The ones that actually come up in chat — answered the way we answer them there.

01

How much does it cost?

It depends on the number of roles, integrations, load requirements and how much data has to be migrated. We do not quote from a description alone: after a 30-minute call we break the task into work items and send a budget range with a risk list within 2–3 business days. That estimate is free and it is yours to keep, even if you build it elsewhere.

02

We do not have a spec. Is that a problem?

No — most tasks arrive that way. In that case we do not start with code, we start with the process: what happens now, where it breaks, what has to stay. The output is a written scope you can take to any contractor. If you already have a spec that describes logic and edge cases, we can start building straight away.

03

Who owns the code?

You do, from the first commit. The repository lives in your organisation, servers and third-party services are registered on your accounts. If we stop working together, there is nothing to hand over — it is already yours.

04

What if we do not like the result?

We work in stages, and you pay stage by stage. If a stage does not satisfy you, we do not start the next one and you pay only for what has been delivered. On sprints you can stop after any two-week cycle. That is why we usually suggest a fixed price for a first project — you risk one known amount.

05

Will you take over an existing system?

Yes, but not blindly. We start with an audit: we read the code, find the bottlenecks and the risks, and say honestly whether it makes sense to keep it or rebuild the weak part. Taking over legacy without an audit is how deadlines get missed, so we do not do it.

06

Our service falls over under load. Can you fix it?

That is one of our main areas. We do not rewrite first — we profile and find where the time is actually spent. Usually it is queries, missing queues or synchronous calls that should have been background jobs. You get a report with the bottlenecks and the cost of fixing each, then we agree what is worth doing.

07

How do you handle financial data?

Access control and roles, an audit log of every operation, idempotency on payment webhooks so nothing is charged twice, secrets outside the repository, backups with restore tested. We write the software — licensing and legal compliance stay on your side, and we will say so plainly rather than pretend otherwise.

08

Who supports it after launch and what does that cost?

Defects that are our fault are fixed under warranty. Beyond that there is a monthly support format with an agreed response time — month to month, no annual contract. You can also take everything in-house: we hand over documentation, deployment instructions and accounts, and that is a normal outcome, not an offence.

09

Do you work under a contract with an EU legal entity?

Yes. We work with legal entities in Ukraine and the EU, sign an NDA on request and send the template with the first message. Closing documents are standard.

10

Why you and not an agency or a freelancer?

Against an agency: no account managers between you and the code, so the person who estimated the task is the person who builds it. Against a freelancer: there is a contract, a process, a repository in your organisation and someone to hand over to. If your task needs thirty people, we are the wrong choice and we will say so.

08 Contact
