Services · Full-Stack Engineering

Software built to last
a decade, not a sprint.

We build web platforms, mobile apps, and API layers that scale with your business — React, Next.js, Spring Boot, Node, Flutter — chosen for the problem, not for familiarity.

Architecture

Modern full-stack platform architecture

Edge-optimized frontend, API gateway, microservices backend, and a polyglot data layer — every tier chosen for its job, every boundary explicit.

Our Approach

Pragmatic choices. No religion.

01

Right Tool for the Job

Next.js when SEO matters, React SPA when it doesn't, Flutter when mobile matters more than web. We don't have a preferred framework — we have requirements.

02

API-First Design

Every API is designed contract-first (OpenAPI 3.1), with consumer-driven contract tests before a line of code is written. Breaking changes are caught in CI.

03

Performance Budgets

Web Vitals targets (LCP <2.5s, INP <200ms, CLS <0.1) enforced in CI via Lighthouse CI. Performance regressions fail the build.

04

Accessibility by Default

WCAG 2.1 AA minimum. axe-core automated checks in CI, manual screen reader review before every release. Accessibility is not a post-launch fix.

What We Solved

Real engagements, measurable outcomes

Energy · Web Platform Rewrite

Customer self-service portal rewrite for a utility provider

An Angular 8 monolith with a Java EE backend — 4.2-second LCP, inaccessible to screen readers, $3M/yr in call center volume from frustrated customers who couldn't self-serve.

Micro-frontend rewrite with Next.js 14 App Router, Spring Boot 3 microservices, Kong API gateway. Feature-by-feature strangler migration over 8 months. Lighthouse CI enforcing performance budgets.

Utilities · Mobile App

Offline-first Flutter app for 1,200 field technicians

Field technicians managed work orders via a mobile browser on aging Android devices — no offline support, constant connectivity drops causing data loss, 40-minute daily paperwork.

Flutter app with SQLite offline-first architecture, background sync via WorkManager, barcode scanning, photo capture with compression, and digital signature capture. Built for Android 8+ on ruggedized devices.

Healthcare · API Modernization

ESB replaced with Node microservices + Kong for a health system

A TIBCO ESB routing 200+ integrations between EMR, billing, and scheduling systems — single point of failure, $2.4M/yr in licensing, and 8-week lead time to add a new integration.

Event-driven microservices in Node.js + TypeScript with Kafka for async messaging, Kong for API gateway and rate limiting, contract tests via Pact for every service boundary.
