What We Build

One Studio Across the Entire Product Stack

From the model to the App Store review — you work with one senior team that owns the full system, not five vendors stitching it together.

AI & LLM Engineering

RAG, autonomous agents, evals, and fine-tuned models shipped behind guardrails you can monitor in production.

Explore AI Services

Mobile App Development

Native iOS and Android, or cross-platform from one codebase — polished apps with offline sync and store delivery.

Explore Mobile Services

Web Apps & SaaS

Realtime dashboards, multi-tenant SaaS, and developer platforms in TypeScript, React, and Next.js — fast and accessible.

Explore Web Services

DevOps & Cloud Reliability

CI/CD pipelines, Kubernetes, IaC, and multi-region AWS/GCP platforms with zero-downtime releases worldwide.

Explore DevOps Services

MySQL & Database Operations

Managed MySQL: HA replication, PITR backups, query tuning, upgrades, and 24/7 monitoring with sub-minute failover.

Explore MySQL Services

Cybersecurity & Protection

WAF and endpoint defense, penetration testing, vulnerability scanning, and a 24/7 SOC that responds while you sleep.

Explore Security Services

24/7 Managed Operations

Follow-the-sun NOC across four global hubs — monitoring, incidents, and on-call with a 15-minute P1 response.

Explore Managed Services

Product Design

Research-led UX, design systems, and prototypes that de-risk the build before production code, with WCAG 2.2 AA built in.

Operated, Not Just Shipped

One Console for Deploys, Databases, and Defense

After launch, our global teams keep your pipelines green, your MySQL fleet healthy, and your perimeter protected — around the clock.

Global Coverage

Delivery That Follows the Sun

Four hubs across three continents hand work to each other every shift. While one team sleeps, the next is monitoring, responding to alerts, and shipping — so your product never waits for a sunrise.

One contract, one accountable team, and local presence in the markets where your users wake up first.

How We Work

From Ambiguous Idea to Operated Product

A fixed, transparent delivery rhythm. You see working software every week and own every commit from day one.

01

Discover

We map users, constraints, and data sources, then define the smallest outcome worth shipping.

02

Prototype

A clickable prototype and a thin-slice AI spike prove the hard assumptions within two weeks.

03

Build

Weekly releases behind feature flags, with evals, tests, and security review built into the sprint.

04

Scale & Operate

Launch, instrument, and iterate. Optional embedded teams keep shipping after go-live.

Client Words

Teams That Ship With Us, Again

Northstack took our AI roadmap from a deck to a product our customers pay for in four months. The evals they put in place caught regressions our old vendor never would have seen.
Mara KesslerVP Product, Helios
The most senior engineering team we have worked with in a decade. They challenged our assumptions, shipped weekly, and left our own engineers stronger than they started.
