Problem Solving

What can Codesiox help you solve?

Whether starting fresh, untangling years of technical debt, or eliminating repetitive operational bottlenecks.

01 • Build

Need new software for your business?

We design and engineer bespoke software mapped directly to your operational workflows, ensuring clean architecture, high performance, and future scalability.

Capabilities:
  • • SaaS platforms & custom web applications
  • • Custom CRM, ERP & internal business portals
  • • Executive dashboards & high-throughput APIs
  • • Automated backend workflow engines
02 • Modernize

Difficult to maintain legacy apps?

Modernize without tearing everything down at once. We untangle monolithic PHP, CodeIgniter, Laravel, and MySQL systems into clean, maintainable architectures.

Capabilities:
  • • Legacy PHP & CodeIgniter refactoring
  • • Monolith to API-first domain decoupling
  • • MySQL database indexing & performance tuning
  • • Automated testing & CI/CD pipeline setup
03 • Automate

Too much time on manual repetitive work?

Deploy targeted AI automation into your operations. We build autonomous agents, document intelligence pipelines, and automated copilots that eliminate human friction.

Capabilities:
  • • Specialized AI agents & workflow automation
  • • Document parsing, OCR & data extraction
  • • RAG systems for internal knowledge bases
  • • CRM & email inbound task automation
Capabilities

Core Engineering Disciplines

We combine software architecture, hands-on development, and AI engineering to solve tangible business challenges.

01 • Service

Custom Software Development

Off-the-shelf software rarely fits intricate business workflows. Codesiox develops tailored software applications engineered directly around how your company operates, from multi-tenant SaaS to high-availability back-office portals.

• SaaS Applications
• Custom CRM & ERP
• Business Portals
• REST / GraphQL APIs
architecture_spec.json REST / API-first
{
  "service": "Custom Business Platform",
  "architecture": "Modular Micro-domain / API-first",
  "frontend": ["Next.js", "TypeScript", "Tailwind CSS"],
  "backend": ["Node.js / Laravel API", "PostgreSQL"],
  "security": ["RBAC", "Audit Logging", "End-to-end Encryption"],
  "deployment": ["Docker", "Automated CI/CD", "Zero-downtime"]
}
02 • Key Differentiator

Legacy Software Modernization

Modernize legacy software without unnecessarily replacing everything at once. We specialize in taking fragile PHP monoliths, outdated CodeIgniter portals, and unindexed MySQL databases, incrementally refactoring them into resilient, high-speed applications while keeping business operations online.

✓ Assessment First: We evaluate existing code and data schemas before touching production.
✓ Strangler Fig Pattern: Incrementally migrate business logic to APIs without big-bang risk.
✓ Database Optimization: Query refactoring, indexing, and migration to modern engines.
Modernization Journey:
01. Legacy Monolith (PHP/MySQL) High Tech Debt

02. Architecture & Domain Boundary Assessment
↓
03. Decoupled REST API Layer + Modern Frontend
↓
04. Automated CI/CD & Cloud Containerization Scale Ready
03 • AI Operations

Practical AI Automation

We do not add generic chat bubbles. We engineer autonomous agents and workflow automations that parse invoices, classify incoming customer data, enrich CRM records, and automate high-friction business operations.

• AI Workflow Agents
• Document Intelligence
• Retrieval-Augmented RAG
• Inbound Lead Automation
Production Workflow Architecture:
Inbound Inquiry / Document Email, Webhook, S3
