The Core Engine: BTI Solution
Business Modeling-driven Enterprise Architecture Transformation
Migration EfficiencyIndustry Leading Index
Comprehensible by business
Empowers business stakeholders to approve modernized requirements through models translated from legacy code.
Accuracy via Scaffolds
Eliminates hallucinations with scaffolds that are base on legacy code structure, transactions, logs, and standards.
Leapfrog with Industry Leading Practices
Accelerates from reusable assets with only c.30% adjustments instead of starting from scratch.
Low-code for Agility
Bridges the gap between IT and business teams and enables organizations to quickly adapt to changing market needs.
Open and Enterprise-level Performance
Scalability, high availability, CI/CD, and resource optimization are enabled by enterprise-scale microservices architecture design for high performance.
BTI Key Capabilities
Leapfrog legacy systems into the future using and asset repository, \nAI-driven modeling, automated code generation, and enterprise integration.
AI-driven Modelling and Modernizing backends
Legacy codes (e.g., COBOL, RPG, 4GL, etc.) re- engineered into industry standardized models (e.g., BPMN, DMN, ERD, etc.) to modernized, enterprise- grade re-architected, re-factored system applications.
Modernized Integration Layer
Replacing legacy integrations (e.g., MOM, RPC, CORBA, DCOM, ETL, FTP, etc.) with real-time, open APIs supporting open-to-open, open-to-host, and host-to-host various integration patterns for online and batch transactions.
AI-driven Testing Automation
Automate white and black-box testing from unit test to functional and non-functional tests covering test outline, test cases, test scripts, test execution, and test reporting.
DevSecOps and Data Pipelines
Streamlines implementation and operations through collaborative CI/CD, automated build to deployment and data migration, quality and security gates, environment and configuration management, alongside with rolling-update releases.
Operational Observability and Governance
Centralized, proactive observability—including end- to-end tracing, real-time dashboards, fault attribution, and resource tracking. Combining stringent compliance, security measures, and comprehensive auditing, it upgrades enterprise operations into proactive firefighting to unified, auditable control.
Assets Repository
Maintains version-controlled, traceable artefacts from requirements to code and testing while enabling the reuse of harvested industry-best-practice assets across customer information, account management, deposits, loans, or other domain-specific work products.
