What We Build On
Building a mobile app is more than writing code - it's picking the right backend for your data model, connecting real-time services where users expect instant feedback, and shipping a product that earns five-star reviews.
Mobile Layer
Single codebase deploying pixel-perfect, high-performance UI to both iOS and Android App Stores, with native API access.
REST API Layer
Structured, secure APIs with clean architecture, RBAC, queue management, and full test coverage.
Real-Time Layer
Auth, Firestore, push notifications, Crashlytics, and real-time synchronization built into the Flutter app.
Cloud Infrastructure
EC2 / Elastic Beanstalk hosting, S3 storage, CloudFront CDN, SES email, and Lambda for background jobs.
Relational Data
ACID-compliant, query-optimized schemas on AWS RDS with automated backups and performance monitoring.
Our Services
From concept to App Store - every capability in-house. No fragmented teams, no handoff chaos.
Pixel-perfect, high-performance cross-platform apps. One codebase ships to both iOS and Android with smooth animations and native API access.
Structured, secure REST APIs with clean architecture, RBAC, queue management, and scalable backend engineering.
Firebase Auth, Firestore, push notifications, Crashlytics, analytics, and real-time synchronization.
EC2, Elastic Beanstalk, S3, CloudFront, SES, and Lambda for scalable, production-grade deployment.
Query-optimized schemas deployed on AWS RDS with automated backups and performance monitoring.
Wireframes, interactive Figma prototypes, design systems, and validated mobile UX before a single widget is built.
Lean Flutter MVP builds focused on validating your core idea fast, without compromising future scalability.
Automated Flutter tests, physical device testing, API load testing, and monitored production releases.
Ongoing Flutter upgrades, OS compatibility updates, security patches, database tuning, and feature releases.
Industries We Serve
Each Flutter app is engineered around the workflows, compliance requirements, and user expectations specific to your sector - not a reskinned template.
HIPAA-aligned, patient-first apps with Firebase Auth, secure PostgreSQL patient records, and AWS-hosted APIs.
Secure mobile wallets and payment apps with encrypted PostgreSQL transactions and Firebase real-time balance updates.
Conversion-optimized shopping apps with Laravel product APIs, S3 media, and PostgreSQL order management.
Driver and dispatch apps with Firebase real-time location tracking, Laravel route APIs, and PostgreSQL fleet data.
Interactive learning apps with S3 video storage, Firebase progress sync, offline caching, and PostgreSQL course data.
Property listing apps powered by Laravel search APIs, PostgreSQL geospatial queries, and S3 photo storage.
Uber-model platforms with Firebase job dispatch, Laravel booking APIs, and real-time worker tracking.
Internal tools and ERP mobile companions that connect to existing PHP backends and enterprise databases.
How It Works
A collaborative engineering partnership, not a factory line. Every stage has clear deliverables, defined ownership, and direct access to the senior engineers building your product.
We map your user personas, core journeys, and technical constraints. Output: written PRD, Flutter architecture plan, API contract, database schema draft, and Firebase service map. Free, no obligation to proceed.
Figma wireframes progress to high-fidelity, Flutter-ready design systems. Interactive prototypes validated with real users before any Dart code is written.
Two-week sprints. Flutter UI, Laravel API, and PostgreSQL schema develop in parallel. Firebase services integrated as features require. Working builds delivered every sprint.
Flutter widget and integration tests run against the full stack. PostgreSQL queries profiled and optimized. APIs load-tested. AWS infrastructure provisioned with monitoring in place.
Submission to both App Store and Google Play from the single codebase. Full source - Flutter/Dart, Laravel, PostgreSQL migrations, Firebase config, AWS infra-as-code - handed over on day one.
Why KSoft Technologies
We've heard the horror stories: blown deadlines, junior developers billed at senior rates, source code held hostage. Here's how KSoft is different.
Every project is led and executed by senior engineers. The engineer you meet in discovery is the one writing your Dart code, designing your APIs, and configuring your infrastructure.
Flutter, PHP, Firebase, AWS, and PostgreSQL because they're the right tools, not the easiest ones to bill for. Each is chosen to solve a specific problem in your architecture.
All Flutter/Dart code, Laravel backend, PostgreSQL migrations, Firebase config, and AWS infrastructure definitions belong to you on day one - no strings, no lock-in.
A strict NDA is signed before any scoping discussion. Your idea, data model, and business logic are protected throughout the engagement and beyond.
Bi-weekly sprint demos, a shared project tracker, direct Slack access to your engineers, and 4-hour response time SLAs. You always know where your project stands.
Over a decade delivering production apps to clients across the US, Europe, Middle East, and Asia. 20+ projects shipped on time.

Questions
Flutter lets KSoft build one codebase that deploys to both iOS and Android with near-native performance and pixel-perfect UI using Dart. It reduces development time compared to maintaining two separate native apps while giving full control over the interface.
PHP with Laravel serves as the REST API layer. Laravel handles business logic, authentication, role-based access control, background queues, and server-side data processing that the Flutter app communicates with securely.
PostgreSQL handles structured relational data such as users, orders, transactions, and permissions. Firebase handles real-time features such as live chat, push notifications, presence indicators, and authentication flows. Many production apps use both.
KSoft uses AWS EC2 or Elastic Beanstalk for Laravel hosting, AWS RDS for PostgreSQL, S3 for media storage, CloudFront for CDN delivery, SES for transactional email, and Lambda for serverless background jobs depending on the app architecture.
Typical KSoft engagements range from $10,000 to $50,000 USD depending on scope - from a lean Flutter MVP with Firebase auth and a basic PHP/PostgreSQL API, to a full-featured app with Laravel API, PostgreSQL schema, and Firebase integrations. A written scope and fixed roadmap follows a free Discovery Sprint, before any commitment.
Timelines depend on scope - an MVP, a full-featured consumer app, or an enterprise build with complex integrations. After discovery, you receive a written scope and fixed roadmap confirming your exact timeline before any work begins.
Yes. You own the Flutter/Dart source code, Laravel PHP codebase, PostgreSQL migration files, Firebase project configuration, and AWS infrastructure setup. IP transfer is included in the contract.
Yes. KSoft audits your existing mobile codebase, rebuilds the mobile layer in Flutter/Dart, and connects it to your existing or newly rebuilt PHP/PostgreSQL backend. Firebase can also be added for real-time features.
Yes. KSoft manages app listings, metadata, screenshots, privacy policy compliance, age ratings, and Apple/Google review correspondence for both App Store and Google Play submissions.
Support covers Flutter and Dart upgrades, iOS/Android compatibility updates, Laravel security patches, PostgreSQL performance tuning, Firebase rule audits, AWS cost optimization, and ongoing feature releases.
