What we can take on
We cover the full lifecycle of a software project: requirements, design, implementation, testing, deployment and support.
Mobile applications
We design and build iOS and Android applications that talk reliably to your systems and pass app store review.

When no off-the-shelf product fits the way you work, we build software around your process instead of the other way round.

We set up the environment your software runs in, so upgrades stop being a risk and problems surface before your customers report them.

How we work
A process without surprises
Every project moves through the same four stages. You always know where things stand, what is being delivered and what comes next.
Understand
We capture what the project must achieve, who will use it and what the constraints are. The stage ends with a written scope.
Design
We define architecture, data model and interfaces, then agree on deliverables and timeline before any production code is written.
Build
We deliver in small working increments with tests. You see progress regularly and give feedback while there is still time to use it.
Launch & support
Controlled deployment, documentation, knowledge transfer and monitoring. We stay available for fixes and later phases.

Why Streamcode
Few people, clear accountability
We are not an agency with layers in between. You talk directly to the engineer building your project.
One point of contact
No handover from salesperson to project manager to developer. The same person knows your project from start to finish.
Code that is genuinely handed over
You get the repository, the documentation and the rights. No lock-in to a platform or to us.
Operations experience, not just development
We run our own systems in production. We know what backups, monitoring, upgrades and a 3 a.m. incident actually involve.
Realistic commitments
If something does not fit the available time or budget, you hear it at the start along with an alternative.
Frequently asked questions
How much does a website or application cost?
It depends on scope. A corporate presentation site is a very different project from an application with user accounts, payments and integrations. After an initial 30-minute conversation you receive a written proposal with a breakdown of deliverables and a fixed price per phase.
How long does a project take?
A corporate website is usually complete in three to six weeks. An application with a database and user roles starts at two to three months for a first working release. The timeline is finalised after the design stage so that it is a commitment rather than a guess.
Do you maintain the project after launch?
Yes. We offer a support agreement covering fixes, security updates, backups and monitoring. You can also take the project in-house — we hand over code and documentation without restrictions.
Do you work with clients outside Greece?
Yes. We are based in Aigaleo, Attica and work remotely with clients across Greece and internationally. Meetings are held by video call and everything agreed is documented in writing.
Can you take over a project someone else started?
Often yes. We begin with a technical review of the existing code and infrastructure to establish what can be kept and what needs rewriting. At the end of the review you receive a written assessment of risks and options, whether or not we continue together.
