Our Modernization & AI Transformation Capabilities

Monolith-to-React Migration

Monolith-to-React Migration

We decouple monolithic WordPress builds into fast, headless React and Next.js frontends, rebuild legacy PHP interfaces into interactive React apps, and upgrade outdated Angular versions into clean, maintainable React libraries.

Backend & Data Engineering

Backend & Data Engineering

Core PHP algorithms shift to Python to power modern AI data pipelines, heavy enterprise Java platforms get streamlined into lightweight Python microservices, and Node.js logic moves to Python for analytics and native LLM integrations.

Mobile Codebase Consolidation

Mobile Codebase Consolidation

We merge separate native iOS and Android builds into one unified, high-performance React Native application, or convert legacy native mobile apps into pixel-perfect Flutter builds for a seamless experience across every device.

AI Integration & Core Systems

AI Integration & Core Systems

OpenAI models are added into your CRM and HRMS for automated reporting and smart assistance, Claude gets deployed across your ERP and workflows for complex document processing, and Gemini's multimodal capabilities go into your CMS.

Chatbots & Agentic AI Systems

Chatbots & Agentic AI Systems

We integrate conversational AI into your CRM, CMS, or HRMS via Botstream.co so your team can query internal databases in plain language, and deploy task-driven AI agents to run data syncs, invoice processing, and transactional workflows.

FAQs

It's the process of upgrading outdated software, infrastructure, or codebases without a full rebuild. We use specialized AI tools to analyze and refactor legacy code (PHP, Java) into modern stacks (Python, React), with senior engineers overseeing every output for production quality.

Not without review. AI tools can miss edge cases or security vulnerabilities. Every line of code we ship goes through mandatory human code audits.

No. We build and test in staging environments using modern API gateways, ensuring zero downtime for your active business operations.

Full rewrites are risky and expensive. Our application modernization services target specific bottlenecks (like decoupling a PHP backend to React) while preserving your proven business rules.

Frontend shifts or AI integrations take 3–6 weeks. Complex enterprise monolith modernizations typically take 8–12 weeks.
