Custom Software for Every Platform.
From bespoke CRM systems that replace Salesforce, to cross-platform mobile apps on Flutter and React Native, to real-time web dashboards and desktop tools — KorTechX engineers software that fits your exact business logic, not the other way around.
Custom CRM Systems
Stop paying monthly subscriptions for tools that almost fit. We build CRMs that are exactly your business.
Full-Stack CRM Development
We design and build bespoke Customer Relationship Management systems tailored to your exact sales pipeline, team structure, and workflow. Unlike Salesforce or HubSpot — your CRM has zero bloat, loads in milliseconds, and is owned by you outright with no recurring license fees.
- Lead capture, scoring & pipeline management
- Role-based access control & team dashboards
- Activity logging, notes & task automation
- Custom reporting & revenue forecasting
CRM Integration & Migration
Already on HubSpot, Salesforce, or Zoho but outgrowing it? We extract your historical data, migrate it cleanly into a purpose-built system, and integrate your new CRM with your email platform, billing system, marketing tools, and WhatsApp — creating one unified source of truth.
- Salesforce / HubSpot data migration
- Email (Mailchimp, SendGrid) integration
- WhatsApp Business API integration
- Stripe / QuickBooks billing sync
AI-Powered CRM Automation
We supercharge your CRM with AI — auto-scoring leads based on behaviour patterns, sending AI-drafted follow-up emails, predicting deal close probability, and routing high-value prospects to the right rep automatically. Your sales team spends time selling, not data entry.
- AI lead scoring & churn prediction
- Automated follow-up sequences
- Deal probability forecasting
- Smart notification & routing rules
Mobile Application Development
Native-quality apps on iOS and Android — shipped from a single codebase using Flutter or React Native.
Flutter — Cross-Platform Excellence
Flutter is our primary recommendation for most mobile projects. A single Dart codebase deploys to iOS, Android, web, and desktop with pixel-perfect, 60fps UI. Google's Material Design 3 and custom widget libraries let us create stunning, brand-consistent interfaces that feel fully native on every device. Flutter apps deploy to App Store and Google Play simultaneously, cutting build time by up to 60%.
- iOS + Android from one codebase
- 60fps smooth animations
- Offline-first with local SQLite sync
- Firebase / Supabase backend integration
React Native — JS Team Acceleration
If your team is already in the React ecosystem, React Native gives your web developers the ability to ship mobile apps using familiar JavaScript/TypeScript skills. We architect React Native projects with Expo for rapid iteration, React Navigation for fluid routing, and NativeBase or Tailwind RN for streamlined UI — giving you a web development speed advantage in the mobile space.
- Ideal for JS/React teams
- Expo managed workflow
- 200,000+ npm package ecosystem
- Over-the-air (OTA) updates
Native iOS & Android
When you need maximum performance, deepest platform integration, or are building for a specialized hardware use case — we develop fully native iOS (Swift / SwiftUI) and Android (Kotlin / Jetpack Compose) applications. Native apps access the full device API surface — ARKit, HealthKit, NFC, advanced camera APIs, and background processing — with no cross-platform abstraction overhead.
- Swift / SwiftUI for iOS
- Kotlin / Jetpack Compose for Android
- Full hardware API access (AR, NFC, Health)
- App Store & Play Store submission
Frameworks & Tools We Use
Web & Desktop Applications
SaaS platforms, enterprise dashboards, and cross-platform desktop tools — all architected for scale.
SaaS Platform Architecture
Multi-tenant SaaS systems with strict data partitioning, horizontal scalability, Stripe billing integration, RBAC, and REST/GraphQL API layers — built to scale from 1 to 1 million users without a single architectural refactor.
- Multi-tenant data isolation
- Subscription billing (Stripe)
- REST & GraphQL API suites
- Auto-scaling cloud deployment
Real-Time Dashboards & BI Tools
High-performance data visualization dashboards using WebSocket, Chart.js, D3.js, and Grafana integrations — ingesting data from multiple APIs and SQL databases and presenting actionable KPIs in real-time to executives and ops teams.
- Live WebSocket data feeds
- Custom chart & graph libraries
- Role-based data filtering
- Multi-source API aggregation
Cross-Platform Desktop Apps
We build Windows, Mac, and Linux desktop applications using Electron or .NET MAUI — accessing local file systems, hardware interfaces (thermal printers, barcode scanners, NFC) while maintaining modern web-quality UI for field ops, warehouse teams, and medical practices.
- Electron (JS-based, all platforms)
- .NET MAUI (enterprise Windows-first)
- Hardware peripheral integrations
- Offline local DB with cloud sync
From Idea to Shipped Product.
A battle-tested engineering process — whether we're building your CRM, mobile app, or enterprise platform.
Discovery & System Architecture
We map every user role, define interaction flows, choose the right platform strategy (Flutter vs Native vs Web), and produce ERDs, API contracts, and system architecture diagrams — all approved before a line of code is written.
UX Design & Clickable Prototype
High-fidelity UI mockups for mobile, web, or desktop — reviewed and approved by your team. Interactive prototypes are produced so you can test flows on a real device before development begins. Zero surprises at launch.
Agile Development in 2-Week Sprints
Development in agile sprints with a clear Definition of Done for every feature. You receive a functioning, testable build every sprint — demonstrated on a staging environment with a bug reporting period before we proceed.
QA, Store Submission & Launch
Comprehensive QA: device testing across 15+ screen sizes, OWASP security testing, load testing, and — for mobile — full App Store and Google Play submission handling including screenshots, store listings, and compliance metadata.
Application Pricing Tiers.
Fixed-scope project pricing for predictable delivery. Ongoing retainers for product teams that never stop shipping.
