Apps & Platforms

Custom web, mobile and backend systems — engineered for production, not slideware. Built, integrated and operated by the same team.

Everything version-controlled, nothing clicked

We build the systems your business runs on.

Custom web, mobile and backend applications — integrated with the ERP, CRM, e-commerce and identity you already use, and operated by the same team that built them. Greenfield builds and legacy modernization, with one accountable engineer in the room.

  • End-to-end — from architecture and design through to on-call.
  • Security in CI — SCA, SAST, secrets and license scans on every PR.
  • EU AI Act & GDPR aware — handled inside the build, not bolted on.

What we ship

Six capabilities, one accountable team.

Web apps

Server-rendered or single-page — picked for the job, not the trend cycle. Symfony, Next.js, Vue/Nuxt and headless commerce stacks.

  • Performance budgets & Core Web Vitals
  • Accessibility (WCAG 2.2) baked in
  • i18n, EN + PL + DE out of the box
Mobile apps

Native (Swift, Kotlin) where it matters, React Native / PWA where it pays. Store submission, code-signing and OTA updates included.

  • iOS & Android
  • Push, offline, deep-linking
  • App Store / Play Store handover
Backend & APIs

REST, GraphQL, gRPC and event-driven services. Queues, schedulers, workflow engines. Designed for replayability, idempotency and observability.

  • PHP/Symfony, Python/FastAPI, Node
  • PostgreSQL, Redis, RabbitMQ/Kafka
  • OpenAPI + contract tests in CI
Integrations

Plug your apps into Obsigen AI, ERP, CRM, payment and identity systems — with proper auth, retries, observability and audit logs.

  • Obsigen AI & other LLM providers
  • SAP, Comarch, Microsoft Dynamics, Salesforce, HubSpot
  • Stripe, Adyen, PayU, BLIK · OIDC / SAML
Platform & ops

Containers, Kubernetes, infra-as-code, observability and SRE — so deploys are boring and rollbacks are 15 minutes, not 15 hours.

  • Docker, K8s, Terraform, Argo
  • Grafana / Loki / Prometheus
  • SLOs, error budgets, on-call
Modernization

Untangle legacy systems gradually — strangler-fig migrations, data extraction, API gateways. No "rewrite from scratch" by default.

  • Legacy code archaeology
  • Phased replatforming
  • Vendor lock-in exit plans
Engagement

From idea to "running in production".

Four phases. Six-to-twelve weeks for a typical engagement, then continuous operation if you want us to keep running it.

1
Discover

Goals, constraints, stakeholders. We write down what "done" means in measurable terms before any code.

2
Design

Architecture, data model, threat model, infra topology. Fixed-price scoping artefact you can sign off on.

3
Build

Weekly demos, shared backlog, tests & security checks in CI. Course-correct early, ship often.

4
Run

Hand-over with runbooks, IaC and on-call rotations. Or we stay and operate it under SLA.

Stack

Opinionated, but not religious.

A pragmatic stack we know well — plus the parts of your stack you already trust.

Backend
PHP / Symfony Python / FastAPI Node.js PostgreSQL Redis
Frontend
Next.js / React Vue / Nuxt Twig Tailwind
Mobile & AI
Swift / Kotlin React Native Obsigen AI Claude / OpenAI
Infra & ops
AWS / GCP / Azure OVHcloud / Hetzner Docker / K8s Terraform Grafana / Loki

…and whatever else makes sense for the job. Tell us what's already in your stack.

FAQ

Questions every CTO asks us.

Do you do greenfield or modernization?

Both. Greenfield is faster but rarer in our pipeline; most engagements involve a working system that needs a new feature, a security uplift, a migration off a stuck vendor, or all three at once.

Can you join our existing team instead of running solo?

Yes — most of our engagements augment, not replace. Shared backlog, your CI, your incident channel. The handover is part of the engagement, not an afterthought.

How do you handle ops after launch?

Three options. (a) Full handover with runbooks, IaC and trained on-call. (b) Co-ops — your team owns weekdays, we own weekends and incidents. (c) Full run & defend retainer with SLA-backed response times.

What about AI inside the application?

If you want AI features inside the app — search, copilots, summarisation, content generation — we use Obsigen AI by default for EEA data residency, or your preferred provider behind a proxy. Either way, the integration is auditable end-to-end.

How fast can a first version ship?

Architecture review in 1–2 weeks. A scoped MVP typically 4–8 weeks. Full production rollout 8–16 weeks depending on integrations and compliance scope. Fixed price after a short scoping sprint.

Will the code be ours?

Yes. All source, infra config and documentation is yours from day one. We work in your repo, not ours, unless you ask otherwise.

Bring a system or a sketch. We look at it together and outline the smallest engagement that gets you to a defensible answer — no slides, no fluff.
