29 apps live on the App Store
Overview

Almost every product problem that surfaces late - flaky features, security scares, data you can't fully trust - traces back to the foundation. A backend is invisible when it's right and everywhere when it's wrong. We design clear data models and documented APIs, build security and observability in from day one, and choose infrastructure that scales with you instead of against your budget.

Who it's for
Products outgrowing a backend that was rushed to launch
Teams that need a documented API for apps or partners
Anyone who's been surprised by a security or data issue
The problem

A shaky backend shows up everywhere.

Flaky features, security gaps, and data you can't fully trust all trace back to the foundation. Fixing it after launch costs far more than getting it right early.

Flaky endpoints and inconsistent data
Security and access control as an afterthought
No visibility when something breaks
Our approach

How we deliver.

01

Model the domain

Clear data models and contracts so every client can rely on consistent behaviour.

02

Secure by default

Authentication, authorization, and validation designed in - not patched on.

03

Observe everything

Structured logging, metrics, and alerts so issues surface before users feel them.

04

Scale deliberately

Infrastructure chosen to grow with load without ballooning your bill.

Read before you build.

Engineering

Multi-tenancy: how to choose before it's expensive to change

Shared schema, database-per-tenant, or sharded? The deciding factor isn't cost - it's what happens when one customer needs something the others don't.

Engineering

MCP is stateless now: what the 2026-07-28 spec changes

The new MCP spec deletes the initialize handshake, sessions, and resumable streams. Your server becomes an ordinary HTTP service - and scales like one.

AI

Background agents: AI that finishes the job after you close the tab

Agents now run for hours at coin-flip reliability. That's why AI is moving from the chat box to durable background workflows that survive crashes and retries.

Engineering

Just use Postgres: one database instead of five

Postgres plus a few extensions now covers search, vectors, queues, documents, and jobs. Add a specialized system only when a real bottleneck forces it.

Engineering

Designing a backend an AI agent can actually use

Agents retry, chain, and act unsupervised - so APIs built for humans break. Idempotency, structured errors, and observability make a backend agent-ready.

Engineering

You probably don't need a vector database

The AI wave pushed everyone toward a dedicated vector database. For most apps, Postgres with pgvector does the job - one fewer system to run, secure, and sync.

Engineering

Your API needs an MCP server (and it's a security boundary)

AI agents are a new class of API consumer, and MCP is how they call your backend. The interesting work isn't the tools - it's auth, scoping, and audit.

How to design an API that lasts (2026)

How to design an API that survives real use: REST vs GraphQL, versioning from day one, and the backward-compatibility rules that stop you breaking clients.

Node.js vs NestJS in 2026: choosing your backend stack

Node.js vs NestJS in 2026: NestJS runs on Node, it's not an alternative. When raw Express is right, when NestJS earns its structure, and where Fastify fits.

SQL vs NoSQL in 2026: why Postgres is the safe default, when a document database actually wins, and how to choose without regretting it later.

FAQ

Questions, answered.

Can you integrate with our existing systems?

Yes - we design APIs and integrations around the systems and data you already run.

Do you document the API?

Always. Clear, versioned documentation is part of the deliverable so your team and partners can build against it confidently.

How do you handle security?

Defense in depth: validated inputs, least-privilege access, encrypted secrets, and security reviewed at every layer.
