EXECUTION METHODOLOGY

5-Phase Agile Delivery Lifecycle

Phase 1: Discovery & Architecture Blueprint
Days 1 – 5

We analyze your business objectives, map complex workflows into technical requirements, and formulate the complete Architecture Blueprint (ERD, data flow, API specs).

Deliverable: Software Requirement Specification (SRS) & System Architecture Diagram
Phase 2: High-Fidelity UI/UX & Interactive Prototype
Days 6 – 12

Our design team drafts click-through interactive prototypes in Figma, confirming user journeys and screen interactions before writing a single line of backend logic.

Deliverable: Approved Clickable Prototype & Design System Tokens
Phase 3: Sprint-Driven Agile Development
Weeks 3 – 6

Development takes place in structured 2-week agile sprints. You receive staging access with continuous continuous deployment so you can test features as they are committed.

Deliverable: Working Staging Environment & Bi-Weekly Sprint Demos
Phase 4: Rigorous QA, Security & Performance Benchmarks
Week 7

Automated unit testing, edge-case validation, SQL injection/XSS vulnerability audits, and high-concurrency load simulations to guarantee stable production execution.

Deliverable: QA Sign-off Report & Security Audit Clearance
Phase 5: Zero-Downtime Deployment & Handover
Week 8+

We orchestrate production server rollout with SSL, automated database backups, log monitoring, complete Git repository handover, and 30-day post-launch warranty.

Deliverable: Production Go-Live, Full Source Code Ownership & Warranty

Frequently Asked Questions

You retain 100% unencumbered intellectual property and copyright ownership. Upon project completion and final milestone sign-off, ExtremeCoder transfers the complete Git repository, database schemas, credentials, and documentation directly to your organization. We never lock clients into proprietary software licenses.

Yes, absolutely. We regularly integrate with existing on-premise ERPs, legacy SQL databases, third-party payment gateways (bKash, Nagad, Stripe, SSLCommerz), courier services, and custom RESTful/SOAP APIs. During Phase 1 Discovery, we map out every integration point to ensure zero data disruption.

Every custom service includes a complimentary 30-day post-launch warranty covering bug fixes, server performance monitoring, and critical issue resolution. Afterwards, we offer flexible SLA maintenance retainers that include monthly security patches, database backups, and feature enhancements.

We offer transparent, fixed-scope milestone billing based on deliverables approved during Phase 1. Typically, projects are structured into: 30% upon blueprint approval, 40% midway upon staging verification, and 30% upon final production deployment and code handover.
