Flexipy OÜ · Python engineering · Estonia, EU
Founders reach us six months in, holding code nobody can maintain. We build production Python systems — and the engineer who designs yours is the one you talk to.
Not case studies we can't show you. Working software, with the engineering problem named.
A builder that turns a structured brief into a working application scaffold — data model, API, admin and deployment — so a project starts from something running rather than an empty repository.
What was technically hard
Generated code has to be code a human wants to maintain six months later. That ruled out template interpolation: the generator works against an intermediate representation and emits idiomatic Django, so the output reads as though someone wrote it.
An AI-native operating system for agencies: CRM, projects, HRM, finance, knowledge base and a team of specialist agents, in one platform working from the agency's own data.
What was technically hard
Giving twenty-five specialist agents access to one shared knowledge base without letting them see across tenant boundaries. Retrieval had to be organisation-scoped at the query layer rather than filtered afterwards, because a filter you forget is a data leak.
An education platform for course delivery, assessment and student progress, built for institutions that are audited on accessibility.
What was technically hard
Assessment under load. Everyone submits in the last hour before a deadline, so the write path has to stay correct while the read path is being hammered, and a partial submission can never be lost.
a European wealth-management platform
Reconciliation ran monthly and compared totals. A break that started on the third of the month surfaced on the first of the next one, by which point the cause was buried under four weeks of writes.
Time to detect a reconciliation break fell from weeks to one day.
a Central European component manufacturer
Line telemetry was written straight into the reporting tables. Duplicate messages inflated output figures, and a network drop left gaps nobody noticed until a plant manager questioned a shift total.
Shift totals now reconcile to the plant's own counts.
Not a list of markets we'd accept work from — the specific failure modes we've had to fix.
Payments and wealth systems that survive an audit, a reconciliation break, and their own growth.

Free. We work out what you actually need built.
Within a week. Scope, sequence and cost, in writing.
Not status reports — software you can click.
With the tests and the deployment you keep.
After launch, included.
If an existing product fits your process, buy it. Here is how we think about the choice.
| Dimension | Building it | When Off-the-shelf SaaS works |
|---|---|---|
| Fit to your process | Built around how you actually work, including the parts that are unusual. | Fits if your process is close to the industry norm — and many are. |
| Time to first value | Weeks. Nothing works until the first release. | Days. This is the real advantage, and it is a big one. |
| Ongoing cost | You own the code and pay to maintain it. | Per-seat forever, but somebody else carries the maintenance. |
| Integrations | Whatever you need, including the internal system nobody else has. | Whatever the vendor supports. Check before you commit. |
| When it breaks | You decide the priority, because it is your team. | You file a ticket and wait with everyone else. |
| Leaving | The code and the data are yours. | Export what the vendor lets you export. |
