01

Discovery & Architecture

We clarify workflows, roles, third-party APIs, performance requirements and fixed acceptance criteria.

02

UI/UX Design & Prototyping

High-fidelity interactive wireframes and UI components approved before code is written.

03

Bi-Weekly Sprints & CI/CD

Iterative bi-weekly sprints with live demo environments, CI/CD automated builds, and testable milestones.

04

Automated QA & Security Audit

Cross-platform device testing, concurrency stress testing, data encryption and security audit.

05

Code Handover & Deployment

Complete Git repository handover, production server rollout, app store submission, and ongoing SLA maintenance.
