Where we can help

When the challenge crosses boundaries.

You need a system that works as a whole. Quantingo is a strong fit when:

  • Your prototype needs to become a production system.
  • Your software needs to work with hardware or edge devices.
  • Your AI feature works in demos but fails in real use.
  • A legacy system is blocking your next product decision.
  • Failures span several layers, and the root cause is unclear.
  • You need someone to define the architecture and build it.

Engineering services

From the first architecture
to the system in production.

Senior technical direction and hands-on delivery, wherever the hard part lives.

01

Custom software & systems architecture

From architecture to production implementation.

Turn a difficult product brief into a clear architecture, working backend and maintainable system. We design APIs, integrate existing platforms and take prototypes into production.

Architecture reviews · Backend platforms · APIs & integrations

02

Embedded, IoT & edge systems

Make connected devices work in the field.

Engineer the full path from device software to cloud services, with provisioning, OTA updates, fleet diagnostics and secure remote access built for day-to-day operation.

Embedded Linux · ARM · Bluetooth / BLE · Device-to-cloud

03

AI, ML & LLM engineering

Move beyond a convincing demo.

Build AI features with evaluation, failure analysis and observability. Combine LLMs, RAG, agents and computer vision with deterministic software that keeps the system under control.

Applied ML · Evaluation · AI-backed APIs · Edge inference

04

Mobile & product engineering

Build the product around the whole system.

Deliver Android applications that connect reliably to APIs, devices and users. Account for offline behavior, on-device AI, real-time visualization and the full publishing lifecycle.

Kotlin / Android · Firebase · Subscriptions · API integration

05

High-reliability & legacy systems

Evolve the system you depend on.

Diagnose difficult failures, modernize legacy software and strengthen testing, builds and deployment. Engineering experience shaped by aerospace and industrial constraints.

Why Quantingo

See the architecture.
Understand the details.

Technical decisions have consequences across the system. We work with those connections in view.

01 /

Architecture + implementation

The same engineering perspective carries through design decisions, working code and debugging.

02 /

Cross-layer understanding

We reason across devices, Linux, networking, APIs, data and product software to solve the whole problem.

03 /

Production discipline

Diagnostics, validation, maintainability and controlled deployment are part of the engineering work.

04 /

Experience with difficult systems

A background spanning aerospace, industrial instrumentation, AI, IoT and mobile products informs practical decisions.

Selected work

Engineering made tangible.

Quantingo’s own products demonstrate the connection between architecture and delivery.
