Services

End to end. Idea to release.

We work the way a senior in-house team would — with architecture, code review, and release discipline. Six service lines, all delivered by the same engineers who designed them.
01 / Web

Modern web apps

Production-grade web products on Next.js, React, and TypeScript — server components, type-safe APIs, edge deployment, and design systems built to scale.

Next.jsReactTypeScriptTailwind
02 / Mobile

Native & cross-platform

Android in Kotlin and Jetpack Compose, cross-platform in Flutter — from MVP to Play Store and App Store release, with clean architecture and long-term maintenance.

03 / AI

AI features & automation

LLM integration, chat assistants, OCR and ML Kit pipelines, RAG over your data, and automation that takes real work off your team's plate.

OpenAIML KitRAGAgents
04 / Backend

APIs, cloud & data

REST and GraphQL services, Firebase and Firestore, Postgres, secure auth, push notifications, and Stripe payment flows wired into your product.

NodeFirebasePostgresStripe
05 / Design

UI/UX & product design

Interfaces translated straight to production — design systems, typography, motion, and dark/light theming that engineering can actually ship.

Design SystemsFigmaMotionTheming
06 / Ship

Refactor, ship & scale

Rescue inherited codebases, modernize architecture, ship to Play Store / App Store / Vercel, and stay on retainer to monitor, patch, and grow.

Process

Five steps, no surprises.

Every engagement follows the same five-stage path. You see the architecture before the code, the build before the release, and the dashboard after.
01 · Discover

Goals, users, scope

Working session to map the product surface, define the MVP, and document non-negotiables before a single screen is drawn.

02 · Architect

Stack & structure

Architecture document, state-management choice, data model, and module boundaries — written down, approved, then built against.

03 · Build

Weekly drops

Internal builds shared weekly via Firebase App Distribution. You see the app evolve, comment in-line, and steer scope in real time.

04 · Ship

Stores & releases

Play Store / App Store listings, release notes, screenshots, staged rollouts, and crash-free baselines before public launch.

05 · Maintain

Patch & iterate

Monthly retainers cover monitoring, SDK upgrades, OS-version compat, and incremental features as the product earns its audience.

Why CodeGraphix

Senior by default.

Four reasons clients keep coming back — pulled directly from the feedback we receive, not a brochure.

Clean, maintainable code

MVVM, BLoC, and Clean Architecture aren't bullet points — they're the baseline. Codebases you can hand to another team without apology.

One-hour responsiveness

Average response time across 17 reviews: 1 hour. You won't lose a workday waiting on a status update or a blocker fix.

Architecture that scales

Built for the next 100k users — modular packages, async pipelines, and data models that survive feature growth without rewrites.

Long-term partnership

Repeat clients across three years and nine countries. We're built for the maintenance phase, not just the launch screenshot.

Studio

Founder-led.

Every project is run, reviewed, and shipped under one senior engineer. No account managers, no junior handoffs.
