Software development

Custom software that feels bought, not built.

From discovery and design through backend, mobile and modernization — we ship senior-led product engineering that holds up in app stores, in audits and in the hands of real users.

Overview

Small senior teams that own the outcome.

Body-shop delivery rarely produces software people want to use. Our pods pair a product lead, designer and senior engineers — accountable end-to-end from problem statement to production release.

Whether you need an MVP, a rewrite of a load-bearing legacy system, or a partner to extend your existing team, we scale the shape of the pod to fit.

  • Discovery & design. Problem framing, prototyping and a plan you can commit to before writing a line of code.
  • Web & mobile. React, Next.js, Swift, Kotlin and React Native shipped with real accessibility and performance budgets.
  • Backend & APIs. Domain-driven services in Go, TypeScript, Java and Python with proper observability from day one.
  • Modernization. Strangler-fig replacements of legacy monoliths without a scary big-bang cutover.
  • Quality engineering. Automated test pyramids, load testing and release gates that let you deploy without heroics.

Sub-capabilities

Nine ways we design and build product software.

Product discovery & design

Framed problems, prototypes and design systems that anchor the whole build.

Web applications

React, Next.js, Vue and Remix front-ends with performance budgets and accessibility built in.

Mobile (iOS, Android, RN)

Native Swift and Kotlin, plus React Native and Flutter for cross-platform speed with quality.

Backend & APIs

REST and GraphQL services in Go, Node, Java and Python with contracts, versioning and metrics.

Micro-services

Domain-driven decomposition, event backbones and service meshes that stay operable.

Legacy modernization

Strangler-fig migration of .NET, Java and mainframe estates without freezing feature delivery.

API integrations & B2B

Salesforce, SAP, NetSuite, ERP and EDI integrations with retries, idempotency and audit trails.

QA & test automation

Playwright, Cypress, XCUITest and Detox pyramids with parallelized CI runs and flake budgets.

Accessibility & performance

WCAG 2.2 AA compliance and Core Web Vitals engineering shipped as part of the definition of done.

Delivery process

From first workshop to a shippable release, predictably.

Discover

Problem framing, user research and a scoped opportunity backlog with rough sizing.

Design

Prototypes, technical architecture, non-functional targets and a delivery plan you can commit to.

Build

Two-week increments, weekly demos, trunk-based development and CI green before merge.

Ship

Progressive rollouts, feature flags, telemetry review and a hardened runbook for support.

Case example
In the field

A logistics app rebuilt from scratch in fourteen weeks.

A national last-mile operator was losing drivers to a slow, crashy in-house Android app. We rebuilt it in Kotlin and React Native for the dispatcher web, integrated three carrier APIs and shipped to 4,200 drivers with zero downtime on cutover weekend.

  • Reduced average route completion time by 17% through better UX and offline sync.
  • Cut crash-free session rate up from 92% to 99.8% on Android 8+.
  • Handled a 3x holiday-season load spike without a single incident.
Common questions

FAQs.

Can you extend our existing engineering team?

Yes. We run embedded pods that plug into your rituals, tooling and code review flow with named senior engineers.

What does an MVP typically cost and take?

Most MVPs land in 8-14 weeks with a pod of four to six. We quote fixed-price after a two-week discovery.

Do you keep code ownership and IP with us?

Always. You own all IP, repositories and credentials on day one , and we hand over so you can operate without us.

Will you maintain what you build?

If you'd like. Our managed engineering team takes over BAU changes, performance work and roadmap increments post-launch.
