SI, From Business to Systems.

We turn customer requirements into stable, connected systemsto create more efficient business environments.

WHAT WE DO

SI · System Integration

We unite fragmented workflows and data in a single system.From requirements to launch and operations, we deliver through six stages.

Defining business requirements and system scope

Requirements · Business analysis

We examine workflows and bottlenecks first, then turn functional, performance, and security needs into measurable criteria.

Current-state analysis
Interviews document workflows, bottlenecks, and exceptions
Measurable requirements
Functional and non-functional criteria for performance, security, and availability
Schedule and risk
Transparent management through a WBS and milestones
Designing system architecture and user flows

Architecture · UX design

We choose a scalable structure for expected traffic and data, then validate real screen flows before development.

Architecture choice
Monolith or microservices selected for traffic and data scale
Early validation
IA, wireframes, and prototypes confirm flows before development
Accessible and responsive
KWCAG accessibility and responsive layouts considered from design
Designing data structures and system integrations

Data · System design

We define data, APIs, migration, backup, and recovery together to secure consistency and recoverability.

Data standards
Standardised ERD and data dictionary plus legacy migration strategy
Interfaces
Existing and external integrations documented as API specifications
Availability
Backup, redundancy, and disaster recovery included in the architecture
Developing and integrating business systems

Development · Integration

Code review, automated testing, and CI/CD manage quality while working releases show progress every cycle.

Built-in quality
Coding standards, reviews, and static analysis applied through CI
Automated testing
Unit and integration tests catch regression defects early
Cycle demonstrations
Working software keeps direction aligned with users
Validating system quality and security

Quality · Security validation

Real scenarios validate performance, security, and user acceptance criteria before launch.

Proven performance
Scenario and load tests verify response and concurrency targets
Security review
Vulnerabilities assessed and remediated against OWASP Top 10
Launch criteria
User acceptance testing secures business approval
Migrating the system and managing service levels

Migration · Operations · Service levels

Migration rehearsals and rollback plans reduce launch risk, while monitoring, SLAs, and improvement work sustain quality.

Minimal disruption
Migration rehearsals and rollback plans reduce service interruption
Operating model
Monitoring, alerts, and SLA-based incident procedures
Continuous improvement
Operational data defines and prioritises improvements
