Services
Four ways we help.
Bring a full specification, or just a problem.
Capabilities
One team, the whole chain of work.
From language models to deployment pipelines, nothing subcontracted.
Web platforms
Web applications and internal portals with real workflows behind them — including moving off a legacy system without halting operations.
Mobile apps
One codebase for iOS and Android, with native modules where the camera, maps, or offline storage have to be used properly.
Internal assistants
Assistants that answer from your own documents and databases, and show where each answer came from.
Document automation
Invoices, contracts, and forms read, checked, and filed into your systems without being retyped.
Search & recommendations
Semantic search and ranking tuned to how your users actually behave, not to alphabetical order.
Integrations
Connecting the systems you already run — ERP, CRM, payment gateways, logistics.
Data & reporting
Database modelling, pipelines, and dashboards whose numbers reconcile with your own books.
Audits & architecture
Technical audits, roadmaps, and due diligence before a budget is signed or a vendor is picked.
How we work
Six stages, one loop.
AI writes most of the code. Judgment, approval, and accountability stay with people.
Intent
Every idea, ticket, or alert becomes one written problem statement — corrected by you before anything is built.
Why Pietra
Why teams choose us.
You are never locked in
The system can move to another team — or to your own — without an archaeology project first. The intent, the spec, and the plan are committed alongside the code, and every project ends with full repository access and a handover session.
A budget that holds
Scope, policy conflicts, and technical choices are settled at intent and design, while changing course still means editing a document rather than rebuilding. Anything that moves the number is discussed before the work starts, not slipped quietly into the final invoice.
Fast, without the gamble
AI writes most of the code, so the schedule compresses and you reach a usable version sooner. Nothing reaches production without an approved plan, passing tests, and a named person's sign-off — so that speed is not paid for with code nobody ever read.
AI only where it pays back
We don't staple a chatbot onto every problem. If a process is cheaper or more reliable without AI, that's what we'll tell you — and what the spec will say — so the budget lands on the one or two places that actually return it.
