What We Do

End-to-End Modernization & Integration

One partner covering strategy, build, cloud, security, quality, and support.

Legacy Monolith Modernization

Decompose legacy, tightly-coupled codebases into modular microservices or modular monoliths without halting live operations.

  • Strangler Fig migration methodology
  • Automated regression test coverage
  • Zero business downtime transition

Cloud-Native Replatforming

Upgrade legacy VMs and bare-metal servers into cloud-native, containerized environments on Kubernetes, AWS, or Azure.

  • Containerization with Docker
  • Serverless adoption where beneficial
  • Infrastructure as Code setup

Enterprise SaaS & Third-Party Integration

Connect disparate enterprise tools: Salesforce, SAP, HubSpot, Stripe, ERPs, and custom internal systems into a unified data flow.

  • Custom bi-directional connectors
  • Webhook handling with retry logic
  • Data transformation middleware

API-Led Connectivity & ESB Replacement

Replace cumbersome Enterprise Service Buses with lightweight API gateways and event brokers for real-time responsiveness.

  • Event-driven architecture (Kafka/RabbitMQ)
  • Lightweight API Gateway routing
  • Standardized RESTful and GraphQL endpoints

Code Refactoring & Security Hardening

Audit and refactor aging codebases to remove security vulnerabilities, deprecated dependencies, and compliance risks.

  • Dependency upgrade roadmaps
  • Static code security analysis (SAST)
  • Automated code formatting and linting

Scalability Re-Engineering

Re-engineer bottlenecks in data access, concurrency, and memory management so older applications can support 10x traffic.

  • Asynchronous worker offloading
  • Distributed Redis cache integration
  • Database read-replica offloading

Frequently Asked Questions

Key considerations regarding our technical execution and delivery models.

How do you modernize legacy software without causing downtime?

We use the Strangler Fig pattern, routing traffic through an API gateway and gradually replacing legacy functions with modern microservices one by one.

What if our legacy system lacks documentation?

Our engineers perform reverse engineering, dynamic code profiling, and automated architectural discovery to map data schemas and business rules thoroughly.
