Service 01 / Engineering

Web & App Engineering

Marketing websites, custom web applications and e-commerce stores — designed to load fast, rank well and convert visitors into customers across India and the GCC.

What's Included

Built to perform

Every build is engineered around speed, search visibility and conversion from day one — not bolted on afterwards.

Marketing & Corporate Websites

Fast, SEO-ready sites with custom design systems, built on modern frameworks and tuned for Core Web Vitals.

Custom Web Applications

Internal tools, client portals and dashboards built with React/Next.js, wired to your data and workflows.

E-commerce Stores

Headless and platform-based storefronts with local payment rails — UPI, Razorpay, PayTabs, Stripe MENA and Tabby.

Performance & Core Web Vitals

Audits and re-engineering for slow legacy sites — faster load times, better rankings, higher conversion.

How We Work

From brief to launch

A tight, transparent process — you always know what's being built and why.

01

Discovery & Audit

We map your goals, audience and existing site (if any), and benchmark it against competitors and Core Web Vitals.

02

Design System

Wireframes and visual design tailored to your brand, built as a reusable component system from the start.

03

Build & Integrate

Development in weekly sprints with staging previews, plus integrations for payments, CRM, analytics and CMS.

04

Launch & Optimize

Go-live with monitoring in place, followed by performance tuning based on real user data.

Why CodeByZeno

Built different.
By design.

01

Native bilingual — not translated

Arabic RTL and English LTR are built simultaneously as one design system. Not a translation job added at the end. That means half the time, zero retrofitting, and design that actually works in both scripts.

02

Core Web Vitals — guaranteed green

We commit to CWV green before final handover, measured on real devices in India and the UAE. LCP under 2.5s, CLS under 0.1 — in writing. Not "should be fast" but "here are the PageSpeed scores."

03

Fixed price — zero scope creep

Everything is scoped and priced upfront. We've never sent a surprise invoice. If anything changes mid-project, we discuss it — we don't just bill for it.
