For when the off-the-shelf stack starts to bend.

Custom web and product engineering. React and Next.js front-ends, Go, Node and Python services, APIs designed as contracts, for the parts of your product that no plugin, theme or SaaS configuration can carry.

10x

performance efficiency from Go services re-architected for high-concurrency loads.

Spec-first

OpenAPI 3.0 contracts validated in CI on every endpoint, every deploy.

Concept to launch

product builds in regulated, real-time markets where performance decides winners.

The problemEvery product hits the point where configuration ends

Every product hits the point where configuration ends.

The CMS handles content. The SaaS handles the standard workflow. Then the business asks for the thing that makes it your product, real-time logic, a custom transaction flow, an integration nobody has built before, and the off-the-shelf stack starts to bend.

  • The workaround tax.

    Plugins stacked on plugins, business logic living in places it shouldn't, every small customization making the next one harder.

  • Integrations held together with hope.

    Point-to-point connections with no contract, no versioning, no tests, where one upstream change breaks three downstream systems.

  • Internal tools staff quietly bypass.

    Admin surfaces so painful that the real workflow lives in spreadsheets, which means your operational data does too.

The answer isn't more configuration. It is engineering the parts that deserve to be engineered.

What we doApplication engineering services

Six services. One build discipline.

One build discipline across all six: the right runtime for each job, an API contract before the code, and resilience on the unhappy path, not just the happy demo.

Service

Modern Front-End Engineering

React, Next.js, TanStack Start. SSR and PWA builds where performance and SEO are product requirements.

Stacks we ship
React · Next.js · TanStack Start · SSR · PWA
Service

Backend Services

Go, Node and Python services. Microservices where they earn their complexity, monoliths where they don't.

Stacks we ship
Go · Node · Python · Kubernetes
Service

API Design & Integration Layer

OpenAPI-first contracts. API-first middleware connecting content, commerce, CRM and data without vendor lock-in.

Stacks we ship
OpenAPI 3.0 · REST · GraphQL · Middleware
Service

Identity, Auth & Payments

The flows where trust is won or lost. Authentication, authorization and payment integrations engineered for security and audit.

Stacks we ship
OAuth · OIDC · Stripe · PCI-aware
Service

Internal Tools & Admin Surfaces

Operational interfaces staff actually use, because a bypassed admin tool is a data integrity problem wearing a UX costume.

Stacks we ship
React admin · Role-based access · Audit logs
Service

Product Engineering, Concept to Launch

Full builds in demanding markets. Real-time logic, regulatory constraints, user experience that has to convert.

Delivery, in the open

Every engagement ships with Bott.

Bott, our engagement agent, carries full project context from day one, reviews every PR with AI, and brings DORA-level delivery transparency to each steering review. On application builds, a production issue moves from a Sentry alert to a fix-PR before standup, so problems get handled while they are still small.

NextBook a build scoping session

Build the part of your product that makes it yours.

If the off-the-shelf stack is bending, or you are about to ask it for something it was never designed to do, let's scope the build properly before the workaround tax compounds.

Engineering is one of four capabilities

The same team carries it through.

We don't hand the work to a build partner and walk out. The people who frame the bet are the people accountable when it ships. Read how the other capabilities plug in.
