How We Work
Our 5-Phase ASP.NET Core Delivery Process
A structured, transparent process built for on-time delivery, zero scope creep, and production-ready software from day one.
Every ASP.NET Core project at QllmSoft follows the same disciplined process — from the first discovery call to post-launch hyper-care. This is how we consistently deliver on complex technical requirements without delays or budget overruns.
Book a Discovery Call01
Discovery & Architecture Design
We start with in-depth business analysis and a detailed technical requirements workshop. Our architects then design a clean, scalable system architecture using ASP.NET Core best practices — with a documented project roadmap and fixed-price scope agreement before any development begins.
02

Our designers build responsive wireframes and interactive prototypes that validate user journeys before code is written. You review and approve every screen — ensuring zero design surprises during development.
03
Agile Development in Sprints
Development happens in 2-week sprints using ASP.NET Core, C#, Entity Framework Core, and SQL Server. Every sprint ends with a demo video, progress report, and your formal sign-off — so you're always in control.
04
QA, Security & Performance Testing
Comprehensive testing covers functionality, load performance, API response times, database optimization, and OWASP security checklists. We use automated regression testing to catch regressions before they reach production.
05
Deployment & 30-Day Hyper-Care
We deploy to your chosen environment (Azure, AWS, or on-premise) and provide a 30-day hyper-care period — covering performance monitoring, bug fixes, security patches, and team handover documentation.
