SERVICES / CUSTOM SOFTWARE

Custom software development for startups and businesses

When an off-the-shelf tool no longer fits your rules, we design and build software around the way your business actually works — then document it so your team can own it.

Business problems we solve

Repeated manual work

Your team re-enters data, reconciles spreadsheets or copies information between systems because no tool follows the real workflow.

Rules that generic tools cannot express

Approval chains, pricing rules, exceptions and permissions are specific to your business, not a template.

Systems that do not talk to each other

CRM, ERP, payment, logistics or internal APIs hold the same customer in different states, and nobody trusts the numbers.

What we build

Internal systems

Operations, approval, inventory, CRM, reporting and back-office tools built around your process.

Backend and APIs

Services, data models, authentication and integrations that other systems can depend on.

Dashboards and reporting

Operational views that answer specific questions rather than displaying every available number.

Integrations

Connecting third-party products, legacy systems and internal services with explicit failure handling.

What you receive

  • A written scope with acceptance criteria and known exclusions.
  • Architecture and data-flow decisions with trade-offs recorded.
  • Source code in a repository you control.
  • Tests for the risky business rules and critical flows.
  • Deployment and environment documentation.
  • A handover walkthrough and a defined support period.

A clear path from idea to delivery.

  1. Discover

    Understand your users, constraints and goals.

  2. Define

    Agree the scope, approach and success criteria.

  3. Build & verify

    Develop in increments with visible progress and testing.

  4. Deliver & evolve

    Release, document and plan what comes next.

Technical capabilities

Architecture

System boundaries, data ownership and failure modes decided before the interface is built.

Full-stack engineering

Web applications, APIs and background jobs using a stack that fits the team that will maintain it.

Security and access

Authentication, roles, audit trails and data handling proportional to the risk.

Quality

Acceptance criteria, automated checks and a tested rollback path before launch.

How we work together

Discovery first

A short discovery produces the scope, risks and estimate before a large commitment.

Phased delivery

Increments that each produce something usable, testable and reviewable.

Direct technical contact

You speak with the people making the technical decisions, not only a sales layer.

Frequently asked questions

How long does a custom system take?

It depends on scope, integrations and data quality. We estimate after discovery and split delivery into increments so you can see progress early.

Do we own the source code?

Yes. The repository and deployment access should belong to you. We document how to run and hand over the system.

Can you work with our existing team?

Yes, when the technical direction and ownership are clear. We can take a defined area or work alongside your engineers.

What if the scope changes?

We record the change, its impact and the decision before doing the work. The goal is to make trade-offs visible, not to hide them in a change request.

Do you provide support after launch?

Support and maintenance are agreed per project. We document the system and define a support period before handover.
