Reliable software for small teams.

We design and maintain web backends, internal tools and data pipelines — the unglamorous systems that keep a business running.

Services

Backend & APIs

REST and gRPC services in Python and Go, with tests, monitoring and sensible deployment.

Internal tools

Dashboards, admin panels and workflow automation that replace spreadsheets and copy-paste.

Data pipelines

Scheduled imports, reporting and clean data models on PostgreSQL and ClickHouse.

Maintenance

Upgrades, security patches and on-call support for systems that already exist.

Recent work

Inventory sync for a regional retailer — nightly reconciliation across four warehouses.
Booking backend for a clinic group — appointments, reminders and reporting.
Logistics reporting — replaced manual weekly spreadsheets with a live dashboard.
