Tech Stack

Technologies We Use

Every technology on this list has been deployed and operated by OKAXI in production. No decorative tech, no resume padding.

Mobile Development

Mobile Development

Cross-platform and native mobile app development. OKAXI delivers Flutter/React Native for shared iOS + Android codebases, plus native Kotlin/Swift when performance demands it.

  • Flutter

    Google's cross-platform mobile framework, providing a shared codebase for iOS, Android, and Web. OKAXI uses it for rapid MVPs and B2B apps requiring consistent UI across every device.

  • React Native

    Meta's React-based cross-platform framework. OKAXI uses it for React-savvy teams, sharing 70–80% of code between iOS and Android with native modules when needed.

  • Kotlin

    Android's official language with native performance and seamless Java interop. OKAXI uses Kotlin for enterprise Android apps demanding high performance and long-term maintainability.

  • Swift

    Apple's language for iOS/iPadOS/macOS, which is type-safe and performance-optimized. OKAXI uses Swift when apps need native iOS performance or deep Apple ecosystem integration (Health, Wallet, ARKit).

Backend Infrastructure

Backend Infrastructure

Three runtime foundations powering every OKAXI system, each chosen by workload (AI/ML, enterprise, realtime).

  • Python

    The primary language for AI/ML, backend automation, and data pipelines. OKAXI builds FastAPI/Django microservices and LLM integrations with LangChain, LlamaIndex.

  • .NET Core

    Microsoft's enterprise platform for mission-critical systems. OKAXI delivers ASP.NET Core APIs and Worker Services for finance and retail clients with high-availability requirements.

  • Node.js

    High-performance runtime for realtime APIs, websockets, and AI service bridges. OKAXI uses Express/Fastify with TypeScript for end-to-end type safety.

Frontend Architecture

Frontend Architecture

A full frontend stack from SEO-friendly static sites to complex enterprise SPAs.

  • React

    React 18+ with Server Components, which is the leading UI framework for complex B2B applications. OKAXI pairs it with Next.js and Astro for fullstack delivery.

  • Vue.js

    Vue 3 with the Composition API, a progressive SPA framework that integrates incrementally into legacy systems. OKAXI uses it for retail POS and enterprise CRM.

  • JavaScript (ES6+)

    Core stack for the modern web, made type-safe with optional TypeScript. OKAXI defaults to TypeScript on every production codebase to reduce runtime bugs by roughly 40%.

  • HTML5 / CSS3

    Modern web standards that form the foundation for SEO, accessibility (a11y), and responsive design. OKAXI strictly follows semantic HTML5 and modern CSS3 features (Grid, Flexbox, Container Queries) on every project.

  • Tailwind CSS

    Utility-first CSS framework for rapid prototyping and production design systems. OKAXI uses Tailwind as the UI baseline on every new project, which reduces custom CSS by roughly 80% and ensures design consistency.

  • Bootstrap

    Reliable UI framework for admin dashboards and internal tools, cutting development time by 30–40% versus hand-rolled CSS.

  • Razor

    .NET view engine for server-rendered enterprise web apps. OKAXI uses Razor Pages for SEO-driven marketing sites and Blazor Server for complex internal admin tools.

Database & Storage

Database & Storage

Database choice driven by business need: RDBMS for transactional, NoSQL for flexible schema, wide-column for large-scale time-series.

  • PostgreSQL

    The strongest open-source RDBMS today, with JSONB, full-text search, and pgvector for RAG. OKAXI's default for transactional workloads.

  • Microsoft SQL Server

    Enterprise RDBMS for legacy systems and Power BI integration. OKAXI supports ongoing operations and migrations to PostgreSQL when clients need them.

  • MongoDB

    Document database for schema-flexible data, logs, and event stores. OKAXI uses it for AI Agent memory, conversation history, and unstructured metadata.

  • Apache Cassandra

    Wide-column NoSQL for large-scale retail systems, supporting realtime GPS tracking, time-series data, and horizontal scaling to billions of records.

Distributed Systems & Cache

Distributed Systems & Cache

Infrastructure for microservices and distributed systems: event streaming, high-performance caching, realtime pub/sub.

  • Apache Kafka

    Event streaming platform for microservices, async AI workflows, and data pipelines. OKAXI systems have handled ~100K events/sec in production.

  • Redis

    In-memory cache + message broker. OKAXI uses it for session storage, rate limiting, RAG vector cache, and realtime Pub/Sub with <1ms latency.

Cloud & DevOps

Cloud & DevOps

Cloud-native infrastructure and automation pipelines. OKAXI deploys on AWS/Azure with Kubernetes orchestration, Docker containerization, and GitHub Actions CI/CD.

  • AWS

    The world's leading cloud provider. OKAXI deploys EC2/ECS/Lambda/S3/RDS for clients needing global scale, with built-in access to 200+ managed services.

  • Microsoft Azure

    Microsoft's cloud platform for enterprises already on the Microsoft stack (.NET, Active Directory, SQL Server). OKAXI uses it for clients needing Office 365 and Power Platform integration.

  • Kubernetes

    Industry-standard container orchestration (K8s). OKAXI deploys K8s clusters for production microservices with load-based auto-scaling and zero-downtime deployment.

  • Docker

    The containerization standard. OKAXI packages every service in Docker containers to ensure complete consistency across dev, staging, and production environments.

  • GitHub Actions

    CI/CD platform natively integrated with GitHub. OKAXI automates build, test, security scan, and deploy with pipeline-as-code, so every commit to main triggers tests and a staging deploy.
