Web & Mobile Engineering

Scalable software. Built to last.

From component systems to distributed backends — we engineer high-performance web and mobile products that stay clean at scale.

01Architecture First

Every system starts on paper, not in an IDE.

System design, clean separation of concerns and scalable data modeling — resolved before a single line of UI is written.

02Frontend Engineering

Interfaces that stay fast as they grow.

Component systems, enforced performance budgets, accessibility as a default, and TypeScript-strict codebases from commit one.

03Backend & API Layer

The layer your product depends on.

REST and GraphQL APIs, authentication, third-party integrations and database design built to hold under real production load.

01Why a specialist

Software built by senior engineers —
not adapted from a template.

Most software fails quietly — not in a demo, but eighteen months later, when the team that shipped it has moved on and every new feature takes longer than the last. That is an architecture failure, not a talent one.

We design the data model and the system boundaries before we design a single screen. Frontend performance budgets and TypeScript-strict discipline are enforced from the first commit, not retrofitted after a client complains.

We build software the way senior engineers would build it for themselves — because at this stage, that is the only standard that matters.

02The discipline

Five disciplines.
One complete engineering process.

Architecture, web, mobile, backend and operations — wired together from the first commit, not stitched on afterward.

04The system

Product Engineering — the release console for your product.

One unified view of health, performance and release status across web and mobile. Owned & engineered by Zerobyte.

The engineering edge

TypeScript-Strict by Default

No `any` escape hatches — types are load-bearing, not decorative.

Performance Budgets

Bundle size and Core Web Vitals gated in CI, not discovered in production.

Component-Driven UI

Design-system-first frontends that stay consistent as teams and features grow.

API-First Backends

Contracts defined and versioned before implementation — frontend and backend move in parallel.

Zero-Downtime Deploys

Blue-green and rolling deploys as the default, not a stretch goal.

Observability Built In

Structured logging, tracing and alerting wired from the first release, not bolted on after an incident.

05How it works

A lifecycle,
not a checklist.

Every engagement runs the same proven loop — from architecture to maintenance — so you always know what stage a build is in and what ships next.

01Architecture

System design and data modeling resolved on paper — before a single screen is built.

06Platform surfaces

Built across every surface.

Web, mobile and the API layer beneath them — engineered as one system, with one architecture and one standard.

Web

Web Applications

  • Next.js / React, server-rendered
  • TypeScript-strict end to end
  • Core Web Vitals gated in CI
  • Deployed on Vercel with edge caching
Mobile

Native & Cross-Platform

  • React Native for iOS & Android
  • Single codebase, native performance
  • Play Store & App Store release pipelines
  • Push, offline-sync and deep linking
API

Backend & Services

  • Node.js services on REST or GraphQL
  • PostgreSQL & Prisma for relational data
  • Auth, billing and third-party integrations
  • AWS Amplify / Firebase for managed infra

Web, mobile and backend are engineered as one system, not three vendors stitched together — one architecture, one team, one standard.
